Nutritional supplements are immensely popular and consumed worldwide. In the United States alone, it is estimated that more than half of all adults consume one or more nutritional supplements regularly or occasionally. Nutritional supplements are available in several different types of formulations for individuals to choose from– including capsules, softgels, tablets, powders, gelcaps, bars, gummies, and liquids. But which is the better format?
In this post, we will focus on comparing the most popular forms: gummies versus capsules. This article will additionally highlight several bioequivalence studies that compare gummies and tablets, and explain why you should consider including an advanced supplement formulation in your diet. The links below can be used to jump ahead to different topics on the page.
Gummy supplements is any type of chewable supplement that has been fortified with a specific vitamin, mineral, botanical compound, or a combination of such. The base ingredients of these chewable gummies are gelatin (or agar agar as a common vegan alternative), sugar, cornstarch, water, and added flavor and/or colorings. With appealing flavors, colors, and shapes, their texture and taste are similar to gummy candies, and hence, gummy supplements are more palatable than supplements in capsule, tablet, and powder formats.
Gummy supplements contain vitamins, minerals, or other nutrients that your body can need if you are not eating a balanced diet. However, certain drawbacks to gummy supplements can negatively impact your health.
Pros: Unlike supplements in powder or tablet form, which are not always palatable, the fruity flavors and candy-like taste of gummy supplements make them very user friendly. The flavors and shapes of gummy supplements make them appealing to children and adults alike. They are easy to chew and are preferred over swallowing supplements in capsule or tablet forms.
Cons: The appealing taste of gummy supplements is due to the presence of added sugar. It is estimated that most gummy supplements contain 2-8 grams of sugar per serving, and hence, they can become an unexpected source of added sugar in the diet. Even sugar-free gummy supplements can contain sugar alcohols that are listed under Total Carbohydrates on the product label. Over-consumption of sugar alcohol can cause diarrhea and bloating, and the safety of the artificial food colorings used in many gummy supplements is still being investigated.
There are also many added ingredients in gummy forms of supplements, making it difficult to tailor to one’s religious or dietary food restrictions.
The appealing flavors of gummy supplements can lead to over-consumption, which, in turn, can cause side effects such as vomiting and diarrhea, or worse, mineral toxicity and the potential risk of liver damage.
Therefore, it is critical to pay attention to the recommended use when taking a gummy supplement to avoid the risks of overdosing.
Before comparing gummy supplements versus capsule supplements, let’s first understand the bioavailability of nutrients in supplement formulations.
The bioavailability of a nutrient refers to the amount that enters the bloodstream. After a nutrient enters the bloodstream, it should then cross the targeted cell membranes so it can exert its beneficial effects. However, the low natural absorption and bioavailability of certain nutrients can adversely affect their beneficial potential. And taking a supplement in higher amounts does not necessarily increase its absorption; instead, it can cause adverse side effects.
The extent of a nutrient’s absorption and bioavailability directly impacts its beneficial effects. When considering gummy supplements versus capsule supplements, you might wonder which is more bioavailable. The bioavailability of any supplement is partially dependent on the eventual dissolution in the body of the supplement preparation, which determines its absorption. The supplement’s coating can also affect its dissolution.
Gummies are chewed and their dissolution begins in the mouth when combined with saliva. The process of dissolution continues in the stomach, with further dissolution in the small intestine.
In contrast, capsules have a shell typically made of gelatin. The active nutrients inside the capsule can be in the form of powder, granules, or liquid. The gelatin shell dissolves in the stomach or bowel and the nutrient molecules are released then. Time-release capsules are designed to release their active ingredients slowly.
Bioequivalence is the property where two supplement types with identical active ingredients display similar bioavailability and produce the same effect at the site of their physiological activity.
The following table highlights several bioequivalence studies that compare the efficacy of gummy supplements versus capsule supplements.

Although studies do show increased bioequivalence of nutrients when in a gummy form, here are some important considerations for capsule supplements beyond just availability: stability and shelf life, dosage accuracy, low sugar content, fewer additives, versatility in formulation, and reduced risk of dental issues.
Whether it is a gummy, a capsule, or a tablet, the absorption and bioavailability of the nutrients in the nutritional supplement depend on how well the supplement is formulated. Whereas, conventional supplement formulations often fail to enhance nutrient bioavailability, advanced formulations can improve the absorption and solubility of the active nutrients by utilizing innovative nutrient delivery approaches, such as:

The following are frequently asked questions (FAQs) about considering including a nutritional supplement in your diet.
Consult your healthcare provider to determine which format works best for you. Gummies or capsules, when taken according to the suggested use, can be equally effective with similar plasma absorption profiles. However, gummy supplements typically have a shorter shelf life than capsules or tablets because of their susceptibility to absorbing moisture, which degrades them faster.
Some nutritional supplements can cause a prescription medication to break down faster than usual, making it less effective. Some nutritional supplements can slow down the breakdown of a medication, making it stay in the body longer and causing side effects. Consult with your healthcare provider before taking a gummy or capsule supplement with a prescription medication.
Read the product label to determine the active nutrients present in the supplement, whether it’s a gummy or a capsule. The product label will also provide information about the inactive ingredients, such as colors and flavors, as well as the expiry date. Always choose a nutritional supplement manufactured by a trusted and reputable manufacturer.
The enhanced bioavailability and absorption of the active nutrients are critical indicators of a supplement formulation’s efficacy.

More than two-thirds of U.S. adults take some form of nutritional supplement. Growing awareness about nutrition and lifestyle and the marketing of nutritional supplements as an option to promote health and wellness have contributed to their popularity. The U.S. nutritional supplements market is flooded with products, including vitamins, minerals, botanicals, amino acids, enzymes, and probiotics. From conventional capsules, tablets, and powders to mass-appealing gummies, drinks, and energy bars, nutritional supplements are available in multiple formats.
When you are considering a nutritional supplement to promote your health and wellness, the obvious question is how to choose a supplement brand. Therefore, in this post, we will explain the key factors you should consider when choosing an excellent supplement brand, and why you should always choose an advanced supplement formulation. Use the links below to jump ahead to a topic of interest.
What Makes A Trusted Supplement Brand? | The Basics of Bioavailability |
Understanding Delivery Technologies | How to Choose A Supplement Brand? A Checklist |
Selecting an Advanced Supplement Formulation |
Before considering including any nutritional supplement in your diet, you should remember that the U.S. Food and Drug Administration (FDA) does not regulate nutritional supplements in the same way as over-the-counter and prescription medications. Supplement manufacturers may sell products without first submitting to the FDA evidence of safety and efficacy of a supplement’s ingredients. This makes it difficult to choose a supplement brand that addresses your nutritional support needs.
Whether you are browsing the websites of online supplement retailers or shopping the aisles at your local pharmacy to find the right supplement for you, the following pointers will help you determine a reliable brand.
Now that we’ve looked at how to determine a reliable brand, let’s look deeper into how supplements interact with your metabolism.
No nutrient is completely absorbed in the body. The proportion of a nutrient that is digested, absorbed, and metabolized through normal body pathways is called its bioavailability. So, the amount of a nutrient present in a supplement formulation does not ensure its efficacy. Instead, the bioavailability of the nutrient makes the difference in its efficacy.
A nutrient’s bioavailability depends on several factors, including:
For example, the naturally low molecular stability of curcumin results in its poor oral bioavailability. As a result, a standard curcumin supplement might provide only minimal health benefits. In contrast, a highly bioavailable curcumin supplement offers significant health-promoting benefits even when a comparatively smaller amount is used.
The following table highlights the importance of nutrient bioavailability in formulating better supplements.

Of course, enhancing nutrient bioavailability and manufacturing supplements with bioavailable ingredients is expensive. This is why not all nutritional supplements are effective. You should always choose a supplement brand that is committed to creating nutritional supplements with optimally bioavailable nutrients.
Ineffective bioavailability through nutrient co-supplementation might improve their bioavailability but sacrifice the formulation’s tolerability and safety. For example, piperine, a component of black pepper, makes curcumin more bioavailable; however, excessive piperine can cause side effects, such as loose stools.
The following table highlights advanced pharmacological approaches that can avoid ineffective bioavailability enhancements.

Although not commonly found on many menus in the West, you may want to consider adding natto to your diet to support heart health and optimal blood flow after reading this article.*
Those new to this traditional Japanese breakfast of fermented soybeans often notice a distinct texture and nutty smell and flavor they may not be familiar with. However, natto is considered a ‘superfood’ owing to its high natural content of vitamins, minerals, protein, and dietary fiber. Studies indicate that natto may be one of the factors that contributes to the longevity of the Japanese population, where it has been consumed as a dietary staple for more than a thousand years.
Recent research has established the health-promoting benefits of nattokinase—the enzyme released by the bacteria during the fermentation of soybeans. In this article, we’ll discuss nattokinase and vascular health and why you should include an advanced nattokinase supplement in your diet. Use the links below to jump ahead to different topics on the page.
Nattokinase, the most active ingredient in natto, is produced by the bacterium Bacillus subtilis during the fermentation of soybeans. Natto’s fermentation biproducts are glutamic acid and polyglutamic acid, both known for their vascular health-promoting benefits.* Chemically, nattokinase is a serine protease enzyme that displays strong fibrinolytic activity—meaning it helps prevent blood clots, enhances vascular permeability, and promotes heart health.*
Nattokinase was first extracted from fermented soybeans in 1987. In commercial nattokinase production, fermentation conditions are optimized, including the temperature, pH, and fermentation time, to enhance its yield. Several other nutrients, including yeast extract, glycerol, shrimp shell powder, and soy peptone, have also been investigated for their ability to enhance nattokinase yield.
Because nattokinase is considered a safe and all-natural supplement for supporting vascular health,* commercial nattokinase supplements are widely used in Japan, Korea, China, the European Union countries, Canada, and the United States for its beneficial fibrinolytic activity and to enhance blood circulation.*
The following table highlights some of the key pharmacological properties of nattokinase.
Pharmacologic Properties of Nattokinase | |
---|---|
Fibrinolytic activity* | Fibrin, an insoluble protein, is produced in response to bleeding. Fibrin helps stop bleeding by forming blood clots. However, an excess of fibrin can form excessive blood clots that could adversely affect heart or brain functions. Nattokinase degrades fibrin directly.* Indirectly, it also increases the release of tissue plasminogen activator (t-PA)—an enzyme that converts plasminogen into its active form, plasmin, which breaks down blood clots.*1 Nattokinase also activates other fibrinolytic enzymes, such as pro-urokinase.* |
Enhancing Blood Flow* | The formation of a blood clot (thrombus) inside a blood vessel is called thrombosis. Thrombosis can obstruct blood flow and is a common underlying cause of several adverse cardiovascular conditions.In an animal study on a thrombus in the common carotid artery, the activity of nattokinase in inhibiting clot formation was stronger than that of other thrombolytic agents, such as plasmin or elastase.*2 |
Antioxidant activity* | Nattokinase exerts beneficial effects on oxidative injury-mediated arterial thrombosis and inflammation-induced thrombosis3 and helps maintain a healthy inflammatory response.* |
Lipid-lowering activity | Nattokinase exerts a direct antioxidant effect, inhibiting the oxidation of low-density lipoprotein (LDL), reducing lipid peroxidation, and enhancing lipid metabolism.*4 |
Neuroprotective activity | The neuroprotective activity of nattokinase is associated with its ability to relax vascular smooth muscle, to protect endothelial cells through enhanced fibrinolytic activity, and to facilitate thrombolysis.*5 |
Prior to the 1980s, there was limited knowledge about the mechanism of action by which nattokinase exerted its cardioprotective effects.* Extensive research now shows that the fibrinolytic activity of nattokinase, in addition to its antioxidant, lipid-lowering, and neuroprotective activities, contributes to its role as a cardioprotective agent. The following table highlights how nattokinase promotes heart health.*
Nattokinase and Heart Health* | |
---|---|
It helps maintain normal blood pressure.* Angiotensin II, a peptide hormone, causes the muscular walls of small arteries to constrict, which can increase blood pressure. Nattokinase contains relatively strong natural inhibitors of angiotensin-converting enzyme (ACE) — a key enzyme responsible for the production of angiotensin II.*6 | |
It helps maintain smooth and supple arteries. Nattokinase’s natural beneficial thrombolytic activity is associated with helping to maintain healthy blood flow in the arteries.*7 | |
It helps maintain normal platelet aggregation.* Although aspirin is commonly prescribed as a blood thinner to restrict blood clotting, the long-term use of aspirin can be associated with serious gastrointestinal side effects. Nattokinase has no such adverse effects on gut health and shows an excellent ability to help maintain normal platelet aggregation.*8 | |
It helps improve lipid metabolism. In a clinical study on the effect of nattokinase on individuals with an excess of fat or lipids in their blood, nattokinase helped maintain normal levels of total cholesterol, triglycerides, and LDL cholesterol.*9 |
Various human and animal trials have shown the correlation between nattokinase and vascular health and how the enzyme provides cardiovascular support by helping to thin the blood and maintain normal blood clotting.
Notably, unlike other common fibrinolytic proteases (uPA and t-PA), nattokinase has no adverse side effects, such as bleeding, which makes it a potent fibrinolytic enzyme for helping to maintain normal blood flow and clot formation.*
Because nattokinase can resist high temperatures (up to 50 degrees Celsius) and high pH (up to 10), it remains intact in the gastrointestinal tract. Unlike most proteins, nattokinase is relatively resistant to the highly acidic gastric fluids in the stomach, so it can be absorbed in the later sections of the digestive tract.
In a human study on the serum pharmacokinetics of nattokinase, intact nattokinase was detected in the blood of healthy participants after they were administered a single oral dose of nattokinase (2000 FU/ 100 mg) in a capsule.10 Furthermore, it has been observed that nattokinase’s oral intake enhances its fibrinolytic activity in the blood.*11 Nattokinase’s oral intake promotes the beneficial release of tissue plasminogen activator from vascular endothelial cells and inhibits the level of plasminogen activator inhibitors.*
However, nattokinase’s large molecular size can make it susceptible to chemical oxidation and subsequent inactivation in the gastrointestinal tract. As a result, various nano-delivery methods have been explored to enhance its stability. An advanced nattokinase supplement formulation can optimize its absorption and bioavailability to achieve nattokinase’s many health-promoting benefits.*
There has been extensive research on nattokinase and vascular health, establishing the cardioprotective effects of the compound. The following are frequently asked questions (FAQs) about nattokinase supplements for vascular health.
In human clinical studies, the no-adverse-effect level (NOAEL) of nattokinase is 10 mg/kg for daily oral intake for 28 days.12 Currently, the recommended use of nattokinase as a nutritional supplement is two capsules (100 mg/capsule) daily.
Although nattokinase is considered safe for oral intake, its potential contraindications with prescription drugs, such as blood thinners, and resulting side effects are relatively unknown. Consult your healthcare provider before taking a nattokinase supplement alone or with a prescription medication.
A nattokinase supplement formulation should optimize its absorption and bioavailability. Look for a supplement formulation that utilizes advanced nutrient delivery nanotechnology and is developed through advanced production and purification technologies.
Tesseract Medical Research has developed an innovative formulation, NattoGuard, which contains a potent combination of nattokinase and two plant terpenes, borneol and trans-cinnamaldehyde, to support optimal heart health.* Tesseract’s proprietary CyLoc® —DexKey® nutrient delivery nanotechnology enhances nattokinase’s bioavailability by protecting it from degradation during transit through the stomach and ensuring its targeted delivery at the desired point in the intestinal tract. The resulting unprecedented absorption and optimal bioavailability make NattoGuard a cardiovascular health-promoting reality.*

Article Summary:
Oxidative stress is an underlying cause of age-related cognitive function decline. It slowly builds up as a result of the aging process, exposure to chemical stressors, parasympathetic nervous system activation, and unrepaired stress damage. Antioxidants that help the brain cope with oxidative stress, such as glutathione, are, therefore, excellent candidates for helping to maintain cognitive function.*
Because the level of glutathione depletes with aging, cognitive functions can be adversely impacted. Glutathione is involved in various metabolic processes, including regulating cellular division and differentiation, detoxification, immune cell function, and scavenging circulating reactive oxygen species (ROS).* Glutathione directly interferes with the oxidation of cellular proteins and limits oxidative stress.* Owing to the close relationship between cognitive function and oxidative stress, glutathione is a well-indicated candidate for helping to maintain cognitive function during aging.*
This article explains the benefits of glutathione for brain health and how Tesseract’s glutathione formulation enables optimal absorption and bioavailability of the body’s ‘master antioxidant’.
Extensive research has studied the role of glutathione in brain health. The following table highlights studies that have established the beneficial correlation between glutathione and neurological health.*

Although glutathione supplementation presents a potentially promising method of maintaining healthy cognitive function, the compound is aggressively and rapidly metabolized by the liver, and dietary glutathione rarely makes it into the bloodstream to capture ROS. Highly bioavailable glutathione supplements contained in sophisticated delivery systems can traffic the molecule through the first pass of metabolism to increase its bioavailability.
The most modern nutrient delivery systems incorporate nanotechnology that encapsulates glutathione in a sphere of fat molecules. After surviving first-pass metabolism, the glutathione supplement needs to find a way to cross the blood-brain barrier so it can scavenge ROS and benefit cognitive function.*
With the right glutathione supplement, the brain’s concentrations of glutathione can be sufficient to help maintain healthy cognitive function.* SafeCell®, developed by Tesseract Medical Research, is an innovative glutathione supplement that solves glutathione’s bioavailability and absorption challenges.
SafeCell’s acetylated glutathione formula utilizes Tesseract’s proprietary CyLoc® – DexKey® nutrient delivery technology to achieve the benefits of glutathione for brain health.* The CyLoc® technology encases glutathione molecules for safe passage through the stomach, and the accompanying Dextrin® reactors release the active glutathione molecules at the desired point in the gastrointestinal tract to achieve their optimal absorption.

The cardiovascular system comprises the heart, arteries, veins, and capillaries and provides blood supply throughout the body. The parasympathetic and sympathetic nervous systems help the circulatory system respond to various stimuli to control the amount and velocity of blood carried through the vessels.
Various factors, such as genetic conditions, infections, lifestyle, and aging, can impact the optimal functioning of the circulatory system. Circulatory dysfunction adversely affects the heart and blood vessels, restricts blood flow throughout the body, and can be the underlying cause of several cardiovascular conditions.
In this post, we discuss the circulatory system, factors that affect its functions, how certain nutrients can support it, and why you should include the best circulation supplements in your diet to promote heart health. Use the links below to jump ahead to different topics on the page.
The cardiovascular system is categorized into two loops:
Let’s understand how the various components of the cardiovascular system work.
Smaller arteries, such as arterioles, have more smooth muscles for contraction and relaxation to regulate blood flow to different body parts. Arterioles face relatively smaller blood pressure and account for most of the resistance in the pulmonary circulation.
Further, micro-circulation consists of a network of small blood vessels—arteries, arterioles, capillaries, venules, and veins. The micro-circulatory network, along with the interstitium and lymphatic vessels, helps maintain the homeostasis of tissues and the entire circulatory system.
Several risk factors can affect the optimal functioning of the cardiovascular system and accordingly increase the risks of adverse cardiovascular conditions. The following table highlights various risk factors that can compromise the cardiovascular system.
Risk Factors Affecting Cardiovascular Functions |

Your dietary choices significantly impact your cardiovascular system. Food sources that are high in sodium, sugar, unhealthy fats, and low in fiber can compromise venous function.1 A balanced diet for circulatory health should consist of fruits and vegetables, fiber-rich foods, and foods that contain omega-3 fatty acids and vitamin E. Adequate hydration is also critical to maintaining cardiovascular health.
A research study has highlighted that nutritional supplements, such as folate, omega-3 fatty acids, vitamin D, and calcium, are beneficial for achieving positive cardiovascular outcomes.2 Furthermore, regular intake of probiotics enhances cardiovascular health by minimizing oxidative stress.
The following table highlights several key nutrients that support circulation, the food sources that are rich in those nutrients, and their benefits.

Quercetin, mainly as Quercetin-3-O-glycoside, primarily serves as a natural pigment in fruits, vegetables, and flowers. Key dietary sources of quercetin include:
Quercetin concentrations can vary from one plant to another and even vary in different parts of the same plant. Onions, tea, and apples contain a significantly higher amount of quercetin.
Flavonoids like quercetin are more powerful antioxidants than vitamins C and E. As a potent antioxidant that supports the body’s natural inflammatory responses, quercetin extends beneficial effects by inhibiting kinases, oxidative damage, and cell cycle growth, and supporting neuronal survival.* The following table lists potential applications for quercetin:

Evidence suggests that the oxidative stress caused by reactive oxygen and nitrogen species plays a critical role in the development of various adverse skin disorders.1 The molecular characteristics of quercetin make it a potent scavenger of these reactive oxygen species (ROS) and reactive nitrogen species (RNS).* Quercetin’s ability to quench free radicals and support the skin’s cutaneous antioxidant defense system makes quercetin a preferred choice for extensive skin care applications.*
Quercetin helps maintain the body’s normal natural inflammatory responses by:
The potential benefits quercetin offers for skin health can be condensed into two main functions: protection and restoration.*

Although quercetin can be obtained in the diet from various fruits and vegetables, it has poor natural absorption in the body.
Studies show that only one percent of quercetin is absorbed naturally when it is ingested orally.5 |
Quercetin’s low natural absorption, extensive metabolism, and rapid elimination from the body contribute to its low bioavailability in nutritional supplements.
Quercetin is primarily absorbed in the upper segment of the small intestine. Post-absorption, quercetin is metabolized in various organs, including the liver, small intestine, colon, and kidney, with the aid of biotransformation enzymes specific to the liver and small intestine. Finally, the kidney excretes quercetin and its metabolites in the urine.
Key factors affecting quercetin’s absorption in the body are:
Conventional approaches used to enhance quercetin’s absorption include consuming the better-absorbed glycosylated form of quercetin, consuming sources with higher quercetin content, and consuming quercetin with dietary components.
The ideal strategy for enhancing quercetin’s bioavailability is to protect its integrity in the upper gastrointestinal tract and release it in the colon with prolonged sustained release. |
Alternative delivery systems, including nanoformulations, help overcome bioavailability-related issues in quercetin supplements. Nutritional supplements formulated at the nanoparticle level achieve a larger surface area compared to their typical raw material counterparts. They can be customized for targeted delivery of quercetin molecules while protecting their integrity against metabolizing enzymes and other physiological conditions. Nanoparticles also enable a controlled release of quercetin molecules at the desired point in the intestinal tract.
The solubility of different forms of quercetin varies. Quercetin aglycones or glycosides in apples, tea, and red wine have lower solubility compared to quercetin glucosides from onions, which appear to have the highest absorption rate.
Quercetin glucoside — the naturally occurring form of quercetin — displays an estimated absorption rate of 3%-17% per 100 mg of ingested quercetin.7 |
Because of its low water solubility, unformulated quercetin ranks low in terms of health-promoting benefits. Although dietary sources support the body with lower concentrations of quercetin, consuming a higher concentration can require taking quercetin in nutritional supplement form. Strategies like structural transformation, absorption enhancers, carrier complexes, and nanotechnology help develop highly bioavailable quercetin supplement formulations for benefits including:
Various formulations of quercetin offer multiple delivery modes, including:
Quercetin intake as a nutritional supplement at one gram daily3 is considered safe; adverse side effects from quercetin supplementation have rarely been reported. However, the clinical results of long-term quercetin use at levels at or above one gram daily for longer than 12 weeks are yet to be determined.
It is always recommended to consult a healthcare provider before including a quercetin nutritional supplement in your diet or taking one with a prescription medicine.
The desired efficacy of a quercetin supplement formulation lies in enhanced bioavailability and absorption of the active nutrient molecules. Tesseract Medical Research’s QuerciSorb Immuphore SR®, an innovative quercetin supplement complex, contains four ingredients — quercetin, zinc, vitamin C, and vitamin D — to support the immune system’s optimal functioning, which includes healthy skin.*
Tesseract’s proprietary CyLoc® – DexKey® technology is a revolutionary nanomolecular nutrient delivery system that enhances the absorption of quercetin molecules by releasing them at the desired point in the intestinal tract. The unprecedented levels of absorption and bioavailability in each quercetin molecule enable micro-dosing of this formulation to achieve quercetin’s skin benefits.*

Hangovers are an all-too-common consequence of both social drinking and binge drinking, and no definitive remedy exists to cure them. Do hangover pills work? Although several products claim to cure hangovers, there is no substantial evidence for their efficacy.
Glutathione is a ‘master antioxidant’ that strengthens immune function, helps maintain a normal inflammatory response, and enables the body to compensate for cellular stress.* Glutathione also plays a key role in detoxification processes in the liver, the organ that works overtime during a hangover. Glutathione’s pharmacological properties make it a potent supplement to address a hangover.
This post discusses the anatomy of a hangover, how glutathione can address a hangover, and why you should include an advanced glutathione supplement in your diet if you do drink. Use the links below to jump ahead to different topics on the page.
The Anatomy of A Hangover | Do Hangover Pills Work? |
Addressing Hangovers by Targeting Oxidative Stress | How does Glutathione Address Hangover? |
Frequently Asked Questions About Glutathione Supplements |
Let’s understand the physiological basis of a hangover. Although a hangover is commonly thought of as simply the body’s reaction to excessive alcohol consumption, the medical basis of a hangover is more nuanced because of the multiple ways in which drinking alcohol affects the body.
The symptoms of hangovers are diverse and can include:
The spectrum of hangover symptoms spans different organ systems. Hangovers have at least four separate pathologies:
A review of hangover research concluded that alcohol’s effect on immune function is the largest contributor to hangover severity and incidence.1 However, that doesn’t mean treating immune function alone is sufficient to minimize a hangover; each pathology produces a different subset of hangover symptoms, and there is no simple way to address all of them at once.
Do hangover pills work? There is no definite answer. The best way to prevent a hangover is to consume alcohol in moderation and ensure adequate hydration when drinking. As people age, their ability to process alcohol decreases, leading to an uptick in unexpected hangovers and individuals seeking hangover remedies, including hangover pills. The following table highlights various hangover remedies.
Common Remedies for Hangover |

The most promising hangover therapies seek to augment the body’s ability to compensate for cellular stress. Rather than simply providing pain relief or restoring lost nutrients, these therapies improve the ability of the immune system to function in the wake of overindulgence in alcohol. Strengthening the immune system is critical because hangover-associated inflammation is a result of immune dysregulation caused by oxidative stress.Significantly, oxidative stress has recently been implicated as one of the primary mechanisms of the immunologic pathology of hangovers.2 In general terms, oxidative stress is a process by which free radicals bond to critical enzymes and cellular molecules, thus preventing them from performing their intended purpose and causing damage. New therapies, such as glutathione supplementation, address hangover pathology by limiting oxidative stress.
Glutathione is a molecule produced by the body that protects cells from oxidative stress by bonding to free radicals with great efficiency, thus preventing damage to cellular machinery.*
In a study evaluating the physiopathological state of alcohol hangovers in the brain cortex of animal models, it was found that glutathione-related enzymes were most affected in nerve terminals.3 When mice were artificially induced to have the conditions of a hangover, the researchers found that 17.5 percent more free radicals were present in their blood than in healthy controls, indicating high levels of oxidative stress. In contrast, glutathione concentrations were found to be 43 percent lower than in controls, and the activity of certain critical enzymes was 40 percent lower.
As oxidative stress increased with the severity of the hangover, the glutathione level of the mice became further depleted. As glutathione levels decreased, the free radicals more easily damaged enzymes, reducing their activity and causing harm to the mice. This harm included a 57-percent increase in the incidence of enzymes responsible for recycling neurotransmitters, suggesting broadly detrimental and wide-ranging mood disturbances. The results of the study imply that a glutathione shortage is a large part of the problem when it comes to the molecular basis of a hangover.
There has also been a randomized double-blind placebo-controlled crossover clinical trial that demonstrated that glutathione supplementation significantly lowered serum acetaldehyde concentrations after alcohol consumption.4 Although it did not significantly affect serum alcohol levels, the reduction in acetaldehyde is crucial, as it is a major contributor to hangover symptoms.4
The following table highlights several studies exploring the effects of glutathione on alcohol metabolism.

Research indicates that glutathione could be an effective hangover therapy by:
A glutathione supplement can act as a safe, effective, and easily accessible alternative to traditional hangover pills. For acute hangovers, glutathione administered intravenously acts faster compared to oral glutathione supplements.
Recently, glutathione supplements have been formulated using nutrient delivery nanotechnology that addresses the metabolic challenges that impact the efficacy of the ‘master antioxidant’. Such formulations enhance the bioavailability of glutathione to better address hangover symptoms and achieve positive outcomes.
Limited data exist on the safety and efficacy of prolonged glutathione supplementation. Because glutathione supplementation in high doses might cause toxicity, consult a healthcare provider before including a glutathione supplement in your diet for long periods.
Limited data exists on the potential contraindications of glutathione with prescription medicines. Consult your healthcare provider before taking a glutathione supplement with a prescription medicine.
Enhanced bioavailability and absorption of glutathione are critical indicators of a supplement formulation’s efficacy.
Tesseract Medical Research’s SafeCell® is an innovative, hypoallergenic S-Acetyl-Glutathione complex formulated for optimal bioavailability and absorption. Tesseract’s proprietary CyLoc® – DexKey® nutrient delivery nanotechnology encases each glutathione molecule, protecting it from early degradation during transit through the stomach. The accompanying DexKey® reactors enable targeted delivery of the active ingredient molecules for enhanced absorption. The result is unprecedented absorption of glutathione in lesser amounts than previously required to support liver health.*
Finally, answering the question, do hangover pills work? There is no definite answer. While glutathione is sometimes included in hangover remedies due to its role in supporting liver detoxification, it should not be considered merely a “hangover pill”. Glutatione plays a much broader role as the body’s “master antioxidant” by supporting liver function, cellular health,and overall physiological balance.
The power of Tesseract’s nutritional supplements lies in enhancing palatability, maximizing solubility, absorption, and bioavailability, and micro-dosing multiple nutrients in a single, highly effective capsule.

Article Summary:
Glutathione, referred to as “the master detoxifier”, is an essential antioxidant present in every cell of the body. It plays a critical role in:
However, several factors can lead to reduced levels of glutathione in the body, such as:
Unfortunately, dietary intake of glutathione-rich foods may not be sufficient to maintain optimal levels. For this reason, glutathione supplementation may be necessary to adequately support various health functions in the body.
But can glutathione be effectively taken as a nutritional supplement? Are there potential side effects? What is the recommended daily intake of glutathione? This article answers frequently asked questions about glutathione supplementation.
Glutathione is commercially available in various delivery forms:
Each of these delivery forms has its advantages and limitations, but oral supplementation remains a widely used and accessible option for most practitioners and patients.
The most common forms of oral glutathione supplements are powders, tablets, and capsules.
Notably, oral glutathione supplements have not been considered the most effective in terms of absorption. Co-supplementation of glutathione with other nutrients can enhance its solubility. For example, one clinical study showed that taking glutathione along with vitamin C can enhance glutathione’s concentration in the blood.*1
Recent research suggests that oral glutathione formulations in liposomal or sublingual forms might be more bioavailable.
The recommended daily oral intake of glutathione is 500mg—1,000 mg. In a balanced diet, fruits and vegetables can contribute up to 50 percent of the recommended intake, while meat consumption typically contributes less than 25 percent.
A glutathione supplement is usually best taken before or after breakfast or dinner. Consult with your healthcare provider to determine the right time to take one.
Glutathione is naturally a difficult-to-absorb molecule; therefore, its health-promoting benefits can be significantly limited due to its poor natural bioavailability and absorption. The following are the common absorption challenges of glutathione:
Common Absorption Challenges of Glutathione |
|
---|---|
|
|
|
Glutathione supplements generally contain between 150 mg and 1,000 mg of glutathione. Consult your healthcare provider to determine the right amount of daily glutathione your body needs to support the targeted health functions.
The safety profile of glutathione supplements is well established, with only minimal side effects reported, such as:
There is limited safety data on prolonged usage of glutathione beyond two months and above 500 mg daily intake. And, if pregnant or breastfeeding, always consult your healthcare provider before including a daily glutathione supplement in your diet.
Various innovative approaches have been explored to enhance glutathione’s absorption and bioavailability, including:
Tesseract Medical Research’s SafeCell® is an S-Acetyl-Glutathione complex that utilizes Tesseract’s proprietary CyLoc® – DexKey® nutrient delivery technology. This nanomolecular nutrient delivery technology addresses the natural bioavailability challenge of glutathione by enabling the unprecedented absorption of billions of glutathione molecules at the optimal point in the intestinal tract — one molecule at a time. This technology unlocks the significant health-promoting potential of this ‘master antioxidant’ molecule to optimally support your health and wellness goals.*

Social media touts berberine as ‘nature’s Ozempic’ and a quick weight-loss solution but what exactly is it? Berberine is bioactive compound derived from plants, such as barberry, Oregon grape, and golden seal, and has a long history of usage in Ayurvedic and Chinese medicine. Although the health-promoting benefits of berberine are well-established, its role as a weight management aid is still being investigated.
This post explains the benefits of adding berberine to your weight management program, why you should consider berberine as a supplement to promote endocrine health, and how Tesseract’s proprietary berberine supplement formulation overcomes berberine’s bioavailability challenges. Use the links below to jump ahead to different topics on the page.
Misinformation about berberine has led to its popularity as an alternative to prescription medications for weight management. But this misinformation about berberine poses risks of its overconsumption or contraindications with prescription medications for weight management, which can result in adverse side effects.
Let’s examine some of the misinformation that surrounds this potent phytochemical.
Misinformation: Berberine is an appetite suppressant.
Fact: There is no conclusive evidence that establishes berberine as a appetite suppressant. Berberine is an antioxidant, its primary mechanism of action is to help maintain normal inflammatory responses in cells.* However, because berberine also promotes normal glucose metabolism and lipid metabolism, it can indirectly promote healthy weight management.*
Misinformation: Berberine is a weight loss agent.
Fact: Berberine does moderate the intestinal absorption of glucose and limits exercise-induced exhaustion and muscle damage, and these effects translate to healthy weight management. More research is required to explore berberine’s role as a weight loss agent. As an antioxidant, berberine can limit oxidative stress post-exercise and lower muscle soreness and physical stress to counter exercise-induced exhaustion.*1 Berberine can also enhance skeletal muscle mass and exert cardioprotective effects.*2 These benefits of berberine enhance physical endurance, which indirectly supports weight management.*
Poor weight management is characterized by abnormal glucose metabolism, which leads to reduced glucose disposal in adipose tissues. Unhealthy weight gain often leads to elevated levels of blood sugar, lipids (fats), and insulin, as well as insulin resistance.
Several studies have investigated berberine’s ability to promote glucose metabolism, and thereby contribute to healthy weight management,* although the exact mechanism of berberine’s action on glucose metabolism is not fully understood. The following table highlights studies that have explored berberine’s role in promoting glucose and lipid metabolism.*
Berberine and Glucose Homeostasis | |
Promoting Insulin Secretion and Addressing Insulin Resistance* | As an antioxidant, berberine protects the insulin-producing cells in the pancreas.* It promotes insulin secretion and reduces insulin resistance through various cellular signal transduction pathways, such as the cyclic adenosine monophosphate (cAMP) pathway.*3 |
Stimulating Glucose Breakdown* | Berberine-induced activation of signaling pathways stimulates the breakdown of glucose into pyruvic acid, thereby releasing energy.*4 |
Inhibiting Glucose Synthesis from Non-carbohydrate Components* | Berberine regulates mitochondria-related pathways, which inhibits glucose synthesis from non-carbohydrate components in liver cells.*5 |
Limiting Digestion of Carbohydrates in the Intestine* | By limiting carbohydrate digestion in the intestine, berberine inhibits intestinal absorption of glucose.*6 |
Promoting Lipid Metabolism* | Insulin is integral to lipid metabolism because it promotes cholesterol biosynthesis and uptake.* Berberine is a known activator of adenosine monophosphate-activated protein kinase (AMPK), which contributes to fatty acid oxidation and limits lipid accumulation, particularly that of low-density lipoprotein cholesterol (LDL-C).*7 |
Although the direct effects of berberine on weight management are still unclear, berberine does influence several mechanisms that indirectly promote weight management. The following are some of the pathways that berberine influences to support weight management.
Berberine promotes the distribution of brown adipose tissue and thermogenesis, and adipose tissue remodeling.*10
The short-term safety profile of berberine is well-established, although there is limited data about its effects on pregnant or breastfeeding women. Berberine can cause mild or infrequent side effects or potential contraindications when taken with certain prescription medications. The following table highlights some of the common side effects of berberine supplements:
Berberine’s Side Effects |
|
---|---|
|
|
|
|
|
The side effects of berberine supplements depend on the delivery route (type of formulation) and the duration of intake. Therefore, it is always recommended to consult your healthcare provider before including a berberine supplement in your diet or taking one with a prescription medication.
Unformulated berberine poses three key challenges that can adversely impact its efficacy:
Most commercially available berberine nutritional supplements contain 400-500 mg of berberine per capsule, with berberine hydrochloride being the primary ingredient. Berberine supplements are usually in the form of tablets, capsules, and fluid extracts.
Compared to unformulated berberine, novel berberine supplement formulations use innovative approaches, such as nanotechnology, to enhance berberine’s palatability and bioavailability to achieve its health-promoting benefits. However, the safety and efficacy of berberine varies greatly depending on the type of formulation.
Here are frequently asked questions (FAQs) about using berberine for weight management:
Berberine can promote healthy weight management,* but it should not be considered as a supplement to achieve quick weight loss. Consult your healthcare provider before including a berberine supplement in your weight management program.
Clinical studies have established that berberine is safe and well-tolerated for short-term use. However, as mentioned earlier, side effects such as flatulence, nausea, constipation, and diarrhea can occur.
Berberine may cause potential contraindications with prescription medications. Always consult with your healthcare provider before including a berberine supplement in your diet or taking it with a prescription medicine for weight management.
The efficacy of a berberine supplement lies in enhanced palatability, bioavailability, and absorption of the berberine molecules. Tesseract Medical Research’s BerberActiv®, an innovative, hypoallergenic berberine supplement formulation, achieves optimal absorption of berberine while enhancing its palatability to achieve user compliance.
Tesseract’s proprietary CyLoc® – DexKey® nutrient delivery nanotechnology ensures unprecedented absorption of berberine molecules in the intestinal tract — one molecule at a time to maximize berberine’s benefits. The CyLoc® matrix encases each berberine molecule in its smart delivery system and masks berberine’s bitter taste. The DexKey® reactors release each berberine molecule at the desired point in the intestinal tract to achieve maximum absorption. Enhanced absorption enables micro-dosing — the ingestion of a lesser amount of berberine to achieve the desired powerful and rapid physiological response.
With better delivery of berberine to the body’s tissues, BerberActiv® supports healthy blood glucose metabolism and lipid metabolism, optimal gastrointestinal and cardiovascular health, healthy weight management, and normal inflammatory and immune responses.*

Are you struggling to manage your weight? Do you feel like no matter what you do, it’s still difficult to meet your health goals? Successful weight management efforts are critical to limiting the cardiovascular risks associated with being overweight, as well as addressing related metabolic, pulmonary, and gastrointestinal conditions. However, many of us are unable to balance our food intake and activity levels due to a variety of both individual and broader reasons. Underlying metabolic conditions further make popular weight management strategies ineffective while medications for weight management often carry the risk of potential side effects. So, is there a natural compound with minimal side effects that can be included in the diet to support weight management efforts?
Research suggests that curcumin is a promising, natural bioactive compound that displays multiple mechanisms of action that beneficially affect cellular biochemical and physiological regulation. The health-promoting benefits of curcumin can address metabolic conditions and the associated unintended weight gain. This post discusses the correlation between gut microbiota and metabolism, the role of curcumin in weight management, and why you should include an advanced curcumin supplement in your diet. Use the links below to jump ahead to different topics on the page.
A healthy gut microbiota is an essential part of maintaining the body’s metabolism and energy balance. A healthy gut microbiota also plays a key role in maintaining immune and metabolic homeostasis and providing protection against pathogens. An imbalance in the gut microbiota can adversely affect the metabolic, immune, and endocrine systems, as well as energy homeostasis and lipid metabolism, all of which can result in weight gain.
Furthermore, the relative lack of diversity in the gut microbiota can disturb the structure and function of the gut’s intestinal barrier, which can cause metabolites and microbes to enter the bloodstream and cause adverse inflammatory responses. This, in turn, may lead to several undesirable metabolic pathways to be over-activated, leading to1:
Beneficial gut bacteria, such as Lactobacillus, Bifidobacterium, and Akkermansia, are traditional probiotics that play an important role in balancing the human intestinal microecology. Supplementation with Akkermansia muciniphilia has been found to enhance metabolic parameters and promote weight loss.2
Curcumin, the polyphenolic active ingredient in turmeric, is an antioxidant known to exert beneficial health effects through multiple mechanisms and biochemical targets.* Curcumin limits oxidative stress and maintains normal inflammatory responses in cells by downregulating the secretions of the pro-inflammatory cytokines, such as the interleukins or TNF-α.*
Research indicates that curcumin can directly regulate the intestinal microflora.* The reciprocal interaction between curcumin and the gut microbiota involves two different phenomena:
Oral intake of curcumin leads to its distribution throughout the intestines, where it benefits the gut microbiota through microbial richness, diversity, and composition.* In diet-induced obese animal models, curcumin supplementation exerted protective metabolic effects by downregulating adverse immune responses in adipose tissues, mediated by alterations in the composition of gut microbiota and the metabolism of curcumin into curcumin-o-glucuronide.3
Curcumin promotes a healthy gut microbiota through:
Curcumin is a safe, natural, and well-tolerated botanical compound. A growing body of evidence suggests that curcumin can be an effective weight management aid. The following table highlights how curcumin exerts its beneficial effects in weight management.

Curcumin has naturally low bioavailability and absorption, which hinders its efficacy in weight management. Curcumin’s chemical instability and water insolubility result in its rapid metabolism in the gastrointestinal tract and systemic elimination from the body. The bioavailability and absorption of free curcumin are reflected in:
Most orally consumed curcumin is eliminated from the body after only minimal systemic absorption. As a result, advanced delivery systems, such as nano-delivery, are often used to improve curcumin’s absorption and efficacy.
The following table highlights the key features you should consider when selecting an advanced curcumin supplement to support your weight management efforts:

TetraCumin® is an advanced supplement formulation developed by Tesseract Medical Research, and is considered one of the best curcumin supplements for supporting weight management.* TetraCumin contains tetrahydrocurcumin and utilizes Tesseract’s proprietary CyLoc® – DexKey® technology — a revolutionary nutrient delivery system that enhances the palatability of the tetrahydrocurcumin molecules, maximizes their absorption and bioavailability, and enables their micro-dosing.
Tesseract’s CyLoc® technology encases each tetrahydrocurcumin molecule in a dextrin fiber delivery cage to mask its unpleasant taste while maintaining its molecular integrity during transit through the stomach. The accompanying DexKey® reactors release the tetrahydrocurcumin molecules at the desired point in the intestinal tract, allowing for their optimal absorption and bioavailability.
The following are frequently asked questions about the usage, safety, and efficacy of utilizing a curcumin nutritional supplement to support weight management:
Unlike unformulated curcumin, a nutritional supplement formulated with a highly absorbable and bioavailable form of curcumin, such as tetrahydrocurcumin, achieves maximum absorption. The enhanced absorption and bioavailability of curcumin in an advanced formulation can achieve curcumin’s benefits for supporting weight management.
Curcuminoids are approved as ‘Generally Recognized as Safe’ (GRAS) by the U.S. Food and Drug Administration and are widely used as a food additive. Curcumin is well-tolerated and safe, up to doses between 4,000 – 8,000 mg daily for 3 months, although doses of 500 mg – 2,000 mg are typically recommended for routine supplementation.
Although curcumin’s safety profile is well-established, consult with your healthcare practitioner before taking it for weight management or taking it with a prescription medicine.
