Article Summary:

Lipoic acid, also known as alpha-lipoic acid (ALA), is a naturally occurring antioxidant synthesized in the human body. It exists in two chemical forms: R-lipoic acid and S-lipoic acid. Of these, R-lipoic acid is the biologically active form, endogenously produced in the body, and present naturally in many foods. In both animal and plant cells, R-lipoic acid serves as an essential cofactor for mitochondrial enzyme complexes, highlighting its role in cellular energy production.* The extensive biological activities of R-lipoic acid translate to numerous benefits for overall health and wellness.* 

Below, we discuss R-lipoic acid’s many benefits and why you should consider an R-lipoic acid supplement in your routine to realize its beneficial potential.

R-Lipoic Acid Benefits — An Overview

The antioxidant properties of R-lipoic acid and its ability to help maintain the body’s natural inflammatory response help mitigate several adverse health conditions characterized by oxidative stress.* The following table highlights the benefits of R-lipoic acid and how it supports various health functions.*

Benefits of R-Lipoic Acid 

a. Antioxidant support
  • The chemical structure of R-lipoic acid supports the elimination of reactive oxygen species.* Lipoic acid and its reduced form, dihydrolipoic acid, can neutralize both reactive oxygen species (ROS) and reactive nitrogen species (RNS).*
  • Dihydrolipoic acid is a potent reducing agent that reduces the oxidized forms of several antioxidants, including coenzyme Q10 and glutathione.*
  • Lipoic acid can inhibit iron- and copper-induced oxidative damage and limit heavy metal toxicity.*
  • Lipoic acid promotes the activation of antioxidant signaling pathways, particularly enhancing glutathione synthesis in cells.*
b. Immune support
  • Clinical evidence suggests1 lipoic acid exerts beneficial effects on the adaptive and innate immune systems.*
  • Lipoic acid up-regulates the function of T cells, B cells, macrophages, and natural killer (NK) cells, which helps maintain balanced immune responses.*
  • Lipoic acid is involved in multiple cell signaling pathways that down-regulate imbalanced inflammatory responses.*
c. Endocrine health support
  • Lipoic acid modulates2 insulin sensitivity and secretion, thereby benefiting glucose metabolism and glucose uptake in cells.*
  • Lipoic acid3 beneficially influences the levels of thyroid hormones — triiodothyronine (T3) and thyroid stimulating hormone (TSH).*
d. Cardiovascular health support
  • Lipoic acid supports the functioning of vascular endothelium, the inner lining of blood vessels, thus playing a critical role in cardiovascular health.* Lipoic acid4 enhances endothelial function by increasing the bioavailability of endothelium-derived nitric oxide (NO).*
  • The antioxidant properties of lipoic acid help limit age-related oxidative stress on the cardiovascular system.* 
e. Neurological health support
  • Lipoic acid exerts neuroprotective effects on neuronal cells, which helps to limit the progression of age-related cognitive impairment.*

The chemical structure of naturally occurring R-lipoic acid in food sources is bound to the amino acid, lysine, within proteins. In contrast, lipoic acid in supplement formulations is not bound to protein, allowing for significantly higher concentrations of this compound compared to dietary sources. 

The safety profile of lipoic acid is well-established, with  daily doses ranging from  200 mg to 2,400 mg generally being well-tolerated and free from adverse side effects. However, due to limited data available on the prolonged usage and potential contraindications of lipoic acid with prescription medications, it is recommended to consult with your healthcare provider before including a lipoic acid supplement in your routine.

The immune system is designed to provide rapid, specific, and protective responses against foreign pathogens while also eliminating toxic or allergenic compounds that may enter through mucosal surfaces. When immune function is compromised, the body’s defense mechanisms weaken, increasing susceptibility to various health conditions.     

Supporting immune function is essential for maintaining overall health. Regular intake of vitamins, minerals, and antioxidants through a balanced diet has been found to promote optimal immune function. However, dietary gaps can occur, and targeted immune health supplements can help fill these nutritional deficiencies.  

What are the most effective supplements and top nutrients for immune system support, and how do they work? In this article, we address these questions–exploring the science behind immune health supplements and their role in supporting overall wellness. Use the links below to jump ahead to different topics on the page.

The Role of Immune Health Supplements

Immune responses are orchestrated by various immune cells, including T cells, B cells, neutrophils, macrophages, dendritic cells, and natural killer cells, among others. These responses are regulated through complex signaling pathways and transcription factors, such as nuclear factor-κB (NF-κB). Although weakened immune responses can increase susceptibility to infections, an overactive immune response may lead to damage of the body’s own tissues, contributing to autoimmunity or an unhealthy inflammatory response.

Immune health supplements come into play as they can strengthen the body’s defense mechanisms against invading pathogens, toxins, and allergens.* These supplements are also instrumental in helping to maintain the body’s normal inflammatory responses and suppressing the overactivation of immune cells by modulating critical cell signaling pathways.*

Common Immune Health Supplements

Vitamins and minerals–including vitamins A, C, D, and E, and selenium and zinc–are common immune health supplements that promote optimal immune function.* Clinical deficiencies of these micronutrients have been associated with weakened immune function.* The following table highlights how these supplements work to promote immune health.* 

Common Immune Health Supplements

Vitamin A 
  1. It is required to form and maintain epithelial tissue that acts as a barrier to pathogens. 
  2. It is involved in the differentiation, maturation, and function of immune cells and in regulating inflammatory cytokines — the signaling molecules secreted by immune cells that promote inflammation. 
  3. Vitamin A deficiency can cause altered immune responses with increased susceptibility to infections. 
Vitamin C
  1. It is an essential nutrient that is critical in influencing both innate and adaptive immunity.*
  2. It exerts antioxidant effects on immune system modulators and helps maintain epithelial integrity.*
  3. Vitamin C enhances the differentiation and proliferation of B and T cells, normalizes cytokine production, and lowers histamine levels —  a signaling chemical often associated with allergic responses.* 
Vitamin D
  1. Almost all immune cells express the vitamin D receptor, which helps vitamin D modulate innate and adaptive immune responses.*
  2. Vitamin D helps maintain a normal inflammatory response and enhances the level and activity of T-regulatory cells — a specialized sub-population of T-cells that suppresses adverse immune reactions.*
  3. Vitamin D deficiency impacts the body’s susceptibility to infections by weakening tissue barriers and impairing macrophage functions.* 
Vitamin E 
  1. It is an antioxidant that helps maintain cell membrane integrity and epithelial barriers. 
  2. Vitamin E enhances antibody production, lymphocyte proliferation, and natural killer cell activity. 
  3. It helps maintain the body’s natural inflammatory response by inhibiting the production of proinflammatory cytokines. 
Selenium
  1. Selenium plays a role in T-cell maturation and function and in natural killer cell activity to support innate and adaptive immune responses. 
  2. Selenium is one of the critical components of antioxidant enzymes, and it helps limit the systemic inflammatory response. 
Zinc
  1. Zinc is necessary for the catalytic activity of several enzymes and plays a role in innate and adaptive immune responses.*
  2. Zinc helps maintain the integrity of tissue barriers, such as the respiratory epithelia.*   

3 Important Botanicals that Promote Immune Health 

Botanicals are plants or plant-derived compounds recognized for their beneficial effects on health and wellness. Many botanicals contain active ingredients that exhibit antioxidant and immunomodulatory properties that promote optimal immune function.* Some common botanicals that benefit immune function include elderberry, garlic, ginseng, green tea, turmeric, barberry, onion, and others. Interestingly, some of these botanicals may already be a part of your diet, contributing to supporting immune function naturally. 

The following sections discuss the immune function benefits of the plant-derived compounds curcumin, quercetin, and berberine.*

Curcumin and Immune Health

Curcumin is a polyphenol extracted from the roots and rhizome of turmeric (Curcuma longa). Curcumin has been shown to target multiple signaling molecules to exert numerous health benefits.* Curcumin is mainly known for exerting antioxidant effects and helping to maintain the body’s natural inflammatory response.* The following table summarizes how curcumin benefits immune health.*

Curcumin’s Beneficial Effects on Immune Health*

Interacting with various immune cells: Curcumin helps to up-regulate various immune cells, including the macrophages, dendritic cells, B, T, and natural killer cells, to strengthen the body’s defense capacity.* 
Altering circulating concentrations of pro-inflammatory cytokines: The intake of curcumin supplements has been found1 to downregulate the activity of pro-inflammatory cytokines, such as IL-1β, IL-4, and vascular endothelial growth factor (VEGF).*
Modulating metabolic pathways: Curcumin inhibits cytokine production and cell proliferation by inhibiting NF-κB target genes involved in inducing immune responses.*

Quercetin and Immune Health

Food rich in quercetin

Quercetin is the most abundant dietary flavonoid in several fruits, green leafy vegetables, and tea. The compound is an antioxidant that scavenges free radicals to protect cellular components from oxidative stress. The antioxidant properties of quercetin help balance various cell signaling pathways to exert therapeutic effects on immune health. 
The following table highlights how quercetin influences immune functions.  

Quercetin’s Benefits for Immune Health*

Inhibiting histamine release: Quercetin helps stabilize mast cells that release histamine, a signaling chemical involved in local immune response communication.*
Inhibiting proinflammatory cytokine production: Quercetin downregulates2 the NF-κβ1 and Iκβ cell signaling pathways, which inhibits the production of proinflammatory cytokines.*
Inhibiting the production of leukotrienes: Quercetin downregulates the production of leukotrienes, the mediators produced in white blood cells that cause adverse immune responses, such as the tightening of airway muscles.*
Enhancing Th1/Th2 balance: Quercetin enhances the balance between T-helper (Th) cell types—Th1 and Th2—critical to beneficial adaptive immune responses.*
Down-regulation of antigen-specific IgE antibody formation: Quercetin inhibits the formation of Immunoglobulin E (IgE) antibodies that trigger antigen-specific allergic reactions.*

 

Berberine and Immune Health

Berberine is one of the primary active ingredients extracted from the roots, rhizomes, and stems of European barberry, goldenseal, Oregon grape, and tree turmeric. It has been traditionally used across cultures for its antioxidative and immunosupportive effects on various health functions.* The following table summarizes how berberine supports immune health.* 

How Berberine Supports Immune Health*

Suppressing pro-inflammatory responses of Th cells: Berberine helps3 suppress functions and differentiation of pro-inflammatory Th1 and Th17 cells, which helps limit cell-mediated inflammatory responses.*
Modulating immune function: Berberine upregulates the functioning of beneficial immune cells, such as dendritic cells, macrophages, and regulatory T cells, which helps to down-regulate adverse immune responses and lower risks of autoimmunity — the condition when the immune system mounts an attack against its own cells.*
Influencing cell signaling pathways: Berberine beneficially interacts with immune cell signaling pathways to inhibit the production of pro-inflammatory cytokines.*

Delivery Technology in Advanced Immune Health Supplements

Although the beneficial health effects of curcumin, quercetin, and berberine are well-established, their poor bioavailability and absorption can hinder their efficacy. The pharmacological properties of these compounds contribute to their limited bioavailability in the body. The distinct bitter taste of unformulated curcumin and berberine further complicates oral ingestion, potentially challenging patient compliance. 

Various approaches have been used to enhance the palatability, solubility, and absorption of these nutrients. Different formulation techniques, such as co-administration with adjuvants, incorporation into micelles, nanoparticles, micro/nanoemulsions, liposomes, and solid dispersions, have been implemented to improve their efficacy. Encapsulation techniques are often preferred to protect the integrity of the nutrient molecules and enhance their functional properties, such as stability, solubility, and controlled release.   

Among encapsulation techniques, nano-delivery systems are considered the most effective in encapsulating the active ingredient and gradually releasing it at the target site.

Antioxidants play a vital role in protecting your body from oxidative stress, a key contributor to aging and chronic health concerns. While starting your day with a nutrient-packed green smoothie or having a colorful salad for lunch are great habits, is it providing your body with all the antioxidants it needs? And when diet alone falls short, what are the best antioxidant supplements to consider? 

In this article, we’ll explore the answers to common questions about antioxidant supplements, including how they counter oxidative stress, promote healthy aging, and leverage advanced antioxidant supplement formulations for optimal absorption. Use the links below to jump ahead to different topics on the page.

What are Antioxidants?

Different types of berries

During normal cellular metabolism, our body produces unstable and reactive molecules known as free radicals. Free radicals are also produced when our body responds to external factors, such as pollution, tobacco smoke, and radiation. An accumulation of free radicals can adversely alter lipids, proteins, DNA, and other cellular components, potentially leading to degenerative conditions. 

‘Antioxidants’ is a broad term for any compound that neutralizes free radicals, preventing their harmful effects. The antioxidants produced by our body (endogenous antioxidants) are classified into enzymatic and non-enzymatic types. Vitamins, minerals, carotenoids, and polyphenols are exogenous antioxidants derived from dietary sources or supplements. The following diagram highlights the classification and examples of antioxidants.  

How do Antioxidants Counter Free Radicals?

Chemically, free radicals contain an unpaired electron in their molecular structures that they can either donate or accept, thus acting as an oxidant or a reducing agent. Reactive oxygen species (ROS), reactive nitrogen species (RNS), reactive chlorine species, and reactive sulfur species are common free radicals generated both during normal cellular metabolism and in response to external soucees like pollution, UV radiation, and smoking.   

Because free radicals lack a full complement of electrons, they can “steal” electrons from other biomolecules, such as lipids, proteins, and DNA. This process, known as oxidative damage, compromises the structure and function of these biomoleculates, potentially leading to cellular dysfunction and disease. Antioxidants give up some of their electrons to neutralize free radicals, thereby breaking the chain reactions that perpetuate oxidative stress at the cellular level. 

Oxidative stress arises when there is an imbalance between free radicals and antioxidants, tipping the scale in favor of free radicales. This imbalance is a critical factor  in the development of numerous adverse health conditions, including cardiovascular diseases, neurodegenerative disorders, and premature aging. 
Notably, antioxidants differ in their capacity to scavenge free radicals, and their activities are significantly correlated with the presence of specific active groups, such as hydroxyl (OH) and amine (NH2) groups. The following table summarizes some common mechanisms through which antioxidants counter free radicals.

How do Antioxidants Counter Free Radicals?

Scavenging free radicals: Primary antioxidants actively inhibit oxidation reactions by scavenging ROS/RNS.
Sequestering transition metal ions: Chelators are a class of secondary antioxidants that bind to transition metal ions and marginalize their reactivity.
Decomposing hydrogen peroxides or hydroperoxides: Some preventative antioxidants reduce hydroperoxides and hydrogen peroxide to alcohol and water without generating free radicals.
Enhancing endogenous antioxidant defense: Endogenous antioxidants, such as reduced glutathione (GSH), regenerate vitamin C from its precursor dehydroascorbic acid (DHA).
Repairing cellular damage: Antioxidant activities include activating transcription factors, such as Nrf2, that activate endogenous antioxidant enzymes to repair cellular damage.

Secondary antioxidants indirectly counter free radicals, including maintaining the body’s natural inflammatory response, inducing protective factors, inhibiting ROS-inducing enzymes (such as xanthine oxidase), and regulating redox-sensitive signal transduction pathways. 

Antioxidants and Healthy Aging

Aging is characterized by a progressive decline in physiological functions, increasing vulnerability to chronic diseases and contributing the natural aging process. One of the key drivers of age-associated changes, including physical impairment and cognitive decline, is mitochondrial dysfunction triggered by oxidative stress. When oxidative stress disrupts their function, it accelerates cellular aging and impairs overall health

Research1 highlights that free radical damage to cells is a major factor behind these undesirable changes associated with aging. By enhancing the body’s antioxidant defense systems, it is possible to mitigate free radical damage, protect mitochondrial integrity, and promote healthy aging. Incorporating adequate antioxidant support into a health regimen may help improve quality of life and slow age-related decline.     

 Antioxidants in Food

Food rich in antioxidants

Research2 has demonstrated that conditions related to oxidative stress can be ameliorated by consuming foods rich in antioxidants. Many natural foods, especially those with at least 0.1% antioxidant content, offer significant properties and may be considered beneficial dietary sources of antioxidants. A well-rounded diet that emphasizes fruits, vegetables, whole grains, teas, and even moderate amounts of wine provides an abundant array of antioxidants, including vitamins, minerals, carotenoids, and polyphenols. 

The following table highlights some common food sources with high antioxidant properties.

Food Sources with High Antioxidant Properties

Fruits: Cranberries, blueberries, strawberries, raspberries, red currants, cherries, figs, guava, pears, oranges, mango, apricots, watermelons, and papaya contain vitamin C, anthocyanins, lycopene, and carotenoids.
Dried fruits: Dried fruits with reduced water content have higher antioxidant capacity than fresh fruits. Dried plums, pears, peaches, apples, figs, dates, and raisins are rich in flavonols such as quercetin and phenolic acids.
Vegetables: Spinach, broccoli, carrots, squash, pumpkin, beetroot, radish, kale, tomatoes, asparagus, avocados, sweet potatoes, bell peppers, and collard greens are high in carotenoids (beta-carotene, lutein, lycopene), sulforaphane, and vitamin C.
Cereals and nuts: Wholegrain cereals contain phenolic compounds, while nuts like walnuts, pecans, and chestnuts are particularly high in polyphenols and vitamin E.
Spices and herbs: Oregano, cinnamon, turmeric, cumin, ginger, pepper, paprika, cardamom, garlic, thyme, sage, and basil not only add flavor to meals but are also rich in antioxidants like curcumin and allicin.
Beverages: Green tea, black tea, apple cider, and red wine have high polyphenol content, including catechins and resveratrol.

Considerations for  Antioxidant Supplements in Your Routine

When endogenous antioxidant defenses are insufficient to protect the body against ROS, supplementation with exogenous antioxidants may help bridge that gap. As we age, the body’s natural antioxidant defense mechanisms are interrupted by elevated ROS production, leading to oxidative stress and its associated health impacts. Nutritional supplements can help replenish the depleted levels of endogenous antioxidants and counter the adverse effects of ROS on cellular and physiological functions.*   
Supplementing with antioxidants has shown potential to delay or ameliorate lifestyle- or age-related health conditions driven by oxidative stress.* The safety and efficacy of antioxidant supplements are well-established with synthetic forms of antioxidants, such as chemically synthesized L-ascorbic acid and RRR-α-Tocopherol, being bioequivalent to their natural forms, vitamins C and E, respectively. 

Absorption of Antioxidant Supplement Formulations

A wide range of factors, including molecular structure, temperature, physiological properties, and the presence of synergistic and pro-oxidant compounds, determines the efficacy of antioxidant compounds. The low molecular weight of certain antioxidants can lose their ability to scavenge free radicals inside cells. 

Antioxidant activities are limited by absorption, distribution, metabolism, excretion, and toxicology processes. The poor absorption of antioxidant supplement formulations is primarily caused by:

  1. Limited permeability into cell membranes.
  1. Degradation in the stomach and intestines. 

Delivery Technology in Advanced Antioxidant Supplements

Various approaches can enhance the bioavailability and absorption of antioxidants to maximize their effectiveness. There are several ways of encapsulating antioxidants, and selecting the appropriate delivery system is critical to optimize antioxidant absorption and activity. 

Among all antioxidant delivery systems, lipid emulsions are commonly preferred owing to their biocompatibility, biodegradability, and relative stability. Emulsions, nanoemulsions, and microemulsions are considered excellent delivery systems for enhancing the bioavailability of antioxidants and minimizing their undesired actions on other cells and tissues. 

Antioxidant supplements formulated with nano-delivery systems are among3 the most effective in encapsulating the active ingredient and gradually releasing it at the target site. 

What are the Top Antioxidant Nutrients?

Not all antioxidant supplements are the same, and each one plays a role in supporting various health functions. So, what are the top antioxidant nutrients? The following table highlights some of the common, commercially available, and top antioxidant nutrients that have been observed to limit oxidative stress and boost the body’s antioxidant defense mechanism.*

Article Summary:

Curcumin is widely recognized for its powerful antioxidant and immunomodulatory properties. However, the low stability and poor systemic bioavailability of curcumin significantly hinders its absorption and effectiveness, posing a challenge for most curcumin nutritional supplements. 

The body breaks down curcumin in the liver before it achieves its active byproduct metabolite, tetrahydrocurcumin (THC), through a process called hydrogenation. As the primary metabolite of curcumin, tetrahydrocurcumin shares many of curcumin’s physiological and pharmacological benefits but stands out as the most potent antioxidant among naturally occurring curcuminoids. With greater stability and bioavailability than curcumin, tetrahydrocurcumin delivers enhanced benefits under physiological conditions, making it a superior option for supporting antioxidant status, immune health, and overall well-being. 

Below, we discuss the benefits of tetrahydrocurcumin, how its benefits differ from curcumin, and why you should include a tetrahydrocurcumin supplement in your diet.   

Why Tetrahydrocurcumin Outshines Curcumin: Key Benefits Explained

The differences in the molecular structures of curcumin and tetrahydrocurcumin result in the functional differences of the two compounds. Tetrahydrocurcumin is more soluble in an aqueous medium, while curcumin is more lipid-soluble. These properties allow THC to achieve high concentrations in the bloodstream and tissues, resulting in higher systemic bioavailability and more pronounced biological effects. The following table summarizes tetrahydrocurcumin’s benefits compared to those of curcumin, highlighting THC’s role as an active ingredient in nutritional supplements.

Tetrahydrocurcumin Benefits Are Superior to Curcumin

a. Tetrahydrocurcumin is a more potent antioxidant agent.* THC is superior to curcumin for upregulating the activity of GSH peroxidase, glutathione-S-transferase, and NADPH quinone reductase — key antioxidant and detoxification enzymes. Studies1 show that THC lowers the levels of lipid peroxidation markers in the blood, liver, and kidney induced cholesterolemia in animal models. This makes THC a more potent antioxidant than curcumin to quench free radicals.*
b. Tetrahydrocurcumin exerts enhanced hepatoprotective effects.* In situations of liver injury, THC displays2 better hepatoprotective effects than the parent compound, curcumin.* THC exerts its beneficial effects on the liver by activating the Keap1-Nrf2 anti-oxidation pathway — a principal protective response against oxidative stress.*
c. Tetrahydrocurcumin exhibits better inhibitory action against inflammatory signaling pathways.* THC has been found3 to be more effective in ameliorating adverse immune responses than curcumin.* It downregulates the IL-4Rα/Jak1/STAT6 pathway—a critical inflammatory signaling pathway–to exhibit better inhibitory action against adverse immune cell responses.*

The body’s inability to convert curcumin into tetrahydrocurcumin rapidly enough results in curcumin being cleared from the bloodstream before it can deliver its full range of benefits. By introducing tetrahydrocurcumin directly into the body, this metabolic conversion step is bypassed, ensuring more effective results.  

Tetrahydrocurcumin is often regarded as a more accessible form of curcumin because of its superior stability and bioavailability, offering enhanced health benefits with greater efficiency. Unlike traditional curcumin supplements, which require higher doses to achieve desired effects, tetrahydrocurcumin supplements provide comparable benefits at much lower quantities. Advanced formulations utilizing nutrient delivery nanotechnology can further enhance the overall solubility and absorption of tetrahydrocurcumin.      

Including A Tetrahydrocurcumin Supplement in Your Diet

Article Summary:

Autism Spectrum Disorder (ASD) refers to a class of conditions associated with delayed development, repetitive/ stereotyped behavior, and impaired language communication, thereby affecting social interaction. Although the exact cause of ASD remains unknown, it is believed that several genetic, metabolic, neurologic, and immunologic factors contribute to the neurodevelopmental condition. 

In children, food selectivity and unusual eating patterns are often associated with ASD. Food selectivity can lead to inadequate nutrient intake, resulting in nutritional deficiencies that further aggravate the condition. Hence, both dietary supplements and medical foods are considered relatively safe and effective ways to fill nutritional gaps in the diets of children with ASD. 

Below, we discuss how both dietary supplements and AuRx®, a medical food developed by Tesseract Medical Research, provides nutritional support to children with ASD.        

How do Dietary Supplements Work for Autism Support? 

As stated above, dietary supplements play a supportive role in managing ASD by addressing nutritional deficiencies, promoting gut health, and supporting neurological function. These targeted interventions may complement other therapies to help improve overall quality of life and alleviate specific symptoms in children with ASD. 

Research has identified  deficiencies in vitamin D1 and omega-3 fatty acids2 among children with ASD. Supplementation with vitamin D3, omega-3 fatty acids, vitamin B12, probiotics, digestive enzymes, butyric acid, folinic acid, and sulforaphane may offer promising benefits, with varied success in alleviating ASD-related symptoms. 

The following table highlights how these dietary supplements can promote neurological and gastrointestinal health in children with ASD, providing clinical insights into their potential therapeutic roles.        

Key Dietary Ingredients & Supplement Nutrients for Autism Support

  • Vitamin D3:
    1. Vitamin D3 is critically involved in neurodevelopment, including neural cell proliferation, neurotransmission, immune function, and addressing oxidative stress.
    2. Vitamin D deficiency during pregnancy and early childhood may significantly impact the developing brain, resulting in adverse neuropathologies, including ASD.
    3. Vitamin D supplementation helps maintain normal inflammatory responses in the brain.
  • Vitamin B12:
    1. Vitamin B12 plays a significant role in inhibiting the toxicity of nitrous oxide (N2O), an air pollutant considered to be a risk factor of ASD.
    2. Studies3 indicate that intramuscular B12 injections and oral folinic acid supplementation can counteract depleted plasma antioxidant concentrations in children with ASD.   
  • Omega-3 fatty acids:
    1. EPA and DHA are the two omega-3 fatty acids critical for brain structure and function. These omega-3 fatty acids are substrates for the production of lipid-based signaling molecules that are necessary for cellular communication and immune regulation. 
    2. Because reduced concentrations of omega-3 fatty acids have been observed in ASD children, supplementation might help alleviate ASD-related symptoms. 
  • Probiotics and digestive enzymes:
    1. The high prevalence of gastrointestinal disturbances in children with ASD indicates the role of the gut-brain axis in influencing both GI and neurological health.
    2. Dietary supplementation of probiotics and digestive enzymes helps restore normal gut microbiota and limits the production and absorption of toxins in the gut.
  • Butyric acid:
    1. The gut microbiomes of children with ASD differ significantly  from those of neurotypical children. A high acidic pH level in their stools indicates an imbalance in the microbiota that can lead to downstream adverse effects on the gastrointestinal and nervous systems through the gut-brain axis. 
    2. Butyric acid is an intracellular signaling molecule and immunoregulator. Studies4 indicate the beneficial role of butyric acid in gene expression in ASD. 
    3. Butyric acid supplementation can enhance gut health by upregulating the beneficial activity of white blood cells in the colon of children with ASD, thereby generating a more normal inflammatory response.
  • Folinic acid:
    1. Dysregulation of the circulating concentrations of homocysteine,an important intermediate in folate and vitamin B12 metabolism, is associated with ASD, reflecting potential impairments in methylation and detoxification pathways. Additionally, ASD is also accompanied by circulating low levels of key antioxidant, glutathione.
    2. Because folic acid is closely related to the metabolism of homocysteine and glutathione, disruptions in folate-related metabolism can increase the risk of ASD.
    3. Supplementation with folinic acid, the reduced form of folate, helps stabilize cerebrospinal fluid folate concentrations, which can improve the neurological symptoms associated with ASD.  
  • Sulforaphane:
    1. A phytonutrient derived from cruciferous vegetables, it is well tolerated, with no toxicity reported in children with ASD.
    2. Sulforaphane exerts beneficial effects against some of the potential causes of ASD, including oxidative stress, DNA damage, and adverse inflammatory responses. 

The efficacy of an autism dietary supplement depends on the bioavailability and absorption of its active nutrients. Before selecting the most suitable supplement for ASD, it is important to consider the active nutrients and delivery system used in the formulation.

Article Summary:

The gut microbiome is a complex and diverse ecosystem of trillions of microorganisms that play a role in maintaining gastrointestinal (GI) homeostasis and supporting numerous metabolic processes. Clinical studies indicate the close association of the health of our gut with our mood, emotions, sleep, and immune system. An imbalance in the gut’s microbial community can contribute to adverse cardiovascular conditions, insulin resistance, metabolic disorders, and dysregulated inflammatory responses. 

Supplements designed to support the gut microbiome can help restore microbial balance and positively influence health functions. But what specific ingredients in these supplements exert therapeutic effects on the body? Below, we discuss several common ingredients found in gut health supplements and their role in promoting normal physiological functions.  

What are the Ingredients in Gut Microbiome Supplement Formulations?

Gut microbiome supplements are categorized into probiotics, prebiotics, and postbiotics. Although food sources, such as yogurt, sauerkraut, and kimchi, can be rich sources of probiotics (good bacteria like Lactobacillus), prebiotics are the fibers and sugars the good bacteria feed on, but the body cannot digest. Postbiotics are bioactive compounds, such as short-chain fatty acids (SCFAs), released by healthy bacteria feeding on their prebiotic food sources. 

The following table highlights common prebiotic and postbiotic ingredients in gut microbiome supplement formulations. 

Common Ingredients of Gut Microbiome Supplements

Butyric Acid: This SCFA is fuel for colon cells (or colonocytes). Research1 shows that butyrate is absorbed into the portal vein and influences vital metabolic processes, including lipid metabolism, glucose homeostasis, and immune responses.*

Ginger: Ginger supplementation has been found2 to benefit the composition of gut microbiota, thereby addressing insulin resistance and limiting the build-up of excess fat in the liver.*

Cinnamon: Cinnamon essential oil helps3 maintain normal inflammatory responses in the GI tract and helps improve the richness and diversity of the intestinal microbiota.* 

Citronella: Citronella essential oil has been found4 to benefit the gut microbiota–inhibiting the growth of harmful bacteria, such as Bacillus sp., E. coli, and Listeria monocytogenes.*

Orange: Bioactive compounds, such as hesperidin and naringin, found primarily in citrus fruit peels enhance the homeostasis of the gut microbiota.*  

Lavender: Lavender oil3 protects the gut microbiota against gastrointestinal insults.*  

Bitter orange: Bitter orange contains bioactive compounds, such as flavonoids, that display antioxidant properties that can mitigate gastrointestinal injury caused by free radicals.* 

Clove: Eugenol, a major compound derived from clove oil, has been found5 to mitigate disruptions to the gut microbiome caused by a high-fat diet (HFD).*

Oregano: Studies indicate6 that oregano essential oil exerts a beneficial effect on the gut’s mucosal barrier and enhances the intestinal microbiota of animal models.* Human studies7,8 have indicated that oregano oil can positively influence the gut microbiome by reducing harmful bacteria and supporting a healthy inflammatory response in the gut.*

Thyme oil: Prolonged intake of a HFD disturbs the composition of gut microbiota. Thyme essential oil can mitigate HFD-induced metabolic disruptions and enhance the gut environment.* 

Marjoram oil: Animal studies9 suggest the potential beneficial activity of marjoram extract against harmful bacterial strains in the gut microbiota.* 

Nigella seeds: Thymoquinone, the primary constituent of black seed oil derived from Nigella sativa, can correct imbalances in the intestinal flora and enhance the diversity of intestinal microbial composition.* 

Turmeric oil: The curcumin in turmeric oil can downregulate adverse inflammatory reactions in the intestine by modulating several cell signaling pathways and beneficially influencing the diversity of gut microbiota.* 

Although the beneficial effects of the above ingredients are well-established, their limited natural bioavailability can hinder the efficacy of most gut microbiome supplement formulations. Fortunately, advanced nutrient delivery technologies, including nanotechnology, enhances the absorption of these ingredients to make them a therapeutic reality.

Article Summary:

Alpha-lipoic acid (ALA) is a critical component in the mitochondria and is necessary for multiple enzymatic functions. Chemically, ALA is present as R- and S-lipoic acid – enantiomers. Although R-lipoic acid is present naturally and is endogenously produced by living organisms, the low quantities of ALA synthesized by the body are insufficient to fulfill the body’s cellular energy requirements. Thus, ALA is mainly obtained from food sources, particularly fruits, vegetables, and meat. Nutritional supplements can also increase the naturally low levels of lipoic acid in the body. 

Below, we discuss how R-lipoic acid acts as an antioxidant and exerts beneficial effects on endocrine health and why you should consider including an advanced lipoic acid supplement in your diet.*

R-Lipoic Acid as An Antioxidant*

ALA plays a vital role in mitochondrial dehydrogenase reactions, which drive cellular energy production.* It also serves as an enzymatic co-factor involved in glucose and lipid metabolism and contributes to the regulation of gene transcription.* Discovered in the 1950s for its antioxidant properties, ALA, along with its reduced form, dihydrolipoic acid (DHLA), is recognized as an excellent antioxidant and free radical scavenger.*

R-lipoic acid, the naturally occurring ALA, has a broad spectrum of action toward boosting the endogenous antioxidant system. One unique characteristic of ALA over other antioxidants is its ability to react as both a lipid-soluble and water-soluble compound. This versatility allows it to protect cellular components across diverse biological systems. The following table summarizes how R-lipoic acid acts as an antioxidant and contributes tooverall health and wellness.*  

How Does R-lipoic Acid Work as An Antioxidant?

  • Restoring the intrinsic antioxidant system: R-lipoic acid protects cellular membranes from the harmful effects of free radicals by interacting with vitamin C and glutathione, which, in turn, recycle vitamin E.* R-lipoic acid also increases the expression of antioxidant enzymes, strengthening the intrinsic antioxidant system, which is the reason it is often called the ‘universal antioxidant.’*  
  • Acting as a chelating agent: Lipoic acid increases glutathione levels in cells that chelate and excrete various toxins, especially toxic metals, from the body.* Lipoic acid is suggested for heavy metal detoxification1, particularly for detoxifying mercury.*   
  • Modulating various signaling pathways: Lipoic acid functions as a redox regulator of proteins, including prolactin, myoglobin, thioredoxin, and NF-kappa B transcription factor.* Lipoic acid upregulates several cell signaling pathways, including oxidant (Nrf2) and insulin signaling.*
  • Acting as a detoxification agent: R-lipoic acid can work2 as a potential first agent for protection from mycotoxins — the toxic compounds produced by fungi or molds.* 
  • Neutralizing reactive oxygen species (ROS): Lipoate, or its reduced form dihydrolipoate, reacts with reactive oxygen species, such as hydroxyl radicals, superoxide radicals, peroxyl radicals, hypochlorous radicals, and singlet oxygen to mitigate oxidative stress.*

The therapeutic benefits of ALA are diminished due to its pharmacokinetic profile, which includes poor bioavailability triggered by its degradation in the liver, reduced solubility, and instability in the stomach. Although R-lipoic acid is more bioavailable than its S-enantiomer, its overall poor bioavailability dictates advanced formulations to enhance its absorption. 

Including An Advanced R-Lipoic Acid Formulation in Your Diet

RLA Pro SR is an innovative R-lipoic acid formulation developed by Tesseract Medical Research. This hypoallergenic formulation contains the R-isomer of lipoic acid for optimized therapeutic efficacy.* The proprietary CyLoc® – DexKey® nutrient delivery nanotechnology further enhances the bioavailability and absorption of lipoic acid, making it a therapeutic reality. 

The CyLoc® technology encases individual R-lipoic acid molecules in its dextrin fiber matrix to protect them from degrading during their transit through the gastrointestinal tract. The accompanying DexKey® reactors release the active nutrient molecules at the desired point in the intestinal tract for maximum absorption. The unprecedented absorption of R-lipoic acid through the gut wall enables micro-dosing — using lesser amounts of active nutrients than previously required to achieve the desired therapeutic outcome. With this revolutionary nutrient delivery smart system, a single capsule of RLA Pro SR can achieve a powerful and immediate physiological response.

Article Summary:

Healthy lungs are critical to your overall health and wellness. Although your body has a natural defense system designed to protect your lungs, continuous exposure to poor air quality, pathogens, and unhealthy lifestyle and dietary habits can compromise lung function. Promoting respiratory health involves creating a cleaner environment (such as allowing for more fresh air circulation), adopting healthier lifestyle choices, and consuming  a nutrient-rich, balanced diet. Nutritional supplements designed to promote respiratory health can help address potential nutritional gaps and provide targeted support for maintaining optimal pulmonary function. 

So, what should you look for when considering supplements that can support your respiratory health? 

Below, we discuss some of the common plant-derived ingredients used in respiratory health supplements and how a proprietary smart delivery system developed by Tesseract Medical Research enhances the absorption of active nutrients. 

Common Ingredients in Respiratory Health Supplements

A diet high in fruits, vegetables, and nutritious beverages is often recommended for respiratory health. Food sources, such as dark leafy vegetables, broccoli, pumpkin, peppers, tomatoes, blueberries, fatty fish, oysters, olive oil, coffee, and green tea, benefit lung function. The therapeutic effects of healthy dietary patterns on respiratory health are largely attributed to the presence of antioxidants in fruits and vegetables. 

Studies indicate that antioxidants exert protective effects against free radicals and limit the extent of cellular damage and inflammation caused by oxidative stress on your respiratory system, especially the lungs. Vitamin C and E, carotenoids, plant polyphenols, and flavonoids are several well-known antioxidants that promote healthy lung function.* Additionally, minerals with antioxidant activity, including selenium, copper, manganese, and zinc, are critical co-factors in supporting the activity of antioxidant enzymes, such as glutathione peroxidases.* Non-enzymatic antioxidants, such as glutathione and coenzyme Q10, can also improve the functional performance of your respiratory system.  

The following table highlights some common plant-derived active ingredients in respiratory health supplement formulations.

Ingredients to Look for in Supplements that Support Lung Health

Article Summary:

Aging is a complex process associated with a progressive decline in cellular and physiological function, accumulation of damaged cells, and an increased risk of adverse chronic health conditions. One of the primary drivers of aging-related changes is the accumulation of cellular damage inflicted by free radicals, particularly reactive oxygen species (ROS). These highly reactive molecules are byproducts of normal metabolic processes but can cause significant harm when their production exceeds the body’s antioxidant defenses. This imbalance, known as oxidative stress, contributes to mitochondrial dysfunction, cell death, and adverse inflammatory responses–key mechanisms underlying aging and age-related disorders. 

Quercetin, a naturally occurring flavonoid found in a variety of fruits and vegetables, offers potential benefits for addressing oxidative stress.. As a lipophilic molecule with potent antioxidant properties, quercetin helps neutralize free radicals and maintain the body’s natural inflammatory responses.* Although the body cannot synthesize  quercetin, dietary intake or supplementation of this flavonoid can play a critical role in mitigating oxidative stress and promoting cellular resilience, thereby supporting healthy aging.* 

Below, we discuss quercetin’s benefits that help slow the progressive decline of essential health functions and support healthy aging.*

How does Quercetin Benefit Healthy Aging?

Quercetin is a bioactive compound commonly present in most diets. Found in different fruits and vegetables, such as apples, red grapes, citrus fruits, cherries, berries, onions, asparagus, and red-leaf lettuce, quercetin is one of the most abundant dietary flavonoids. Its diverse biological activities make quercetin a valuable nutrient for promoting healthy aging and supporting overall cellular health by functioning as an:

The following table highlights the mechanisms through which quercetin exerts its benefits on aging. 

How does Quercetin Support Healthy Aging? 

  • Limiting bone mass and bone mineral loss: Bone degeneration is a major aging-related condition. Quercetin benefits bone structure and the conformation of bone morphogenetic proteins (BMPs) through the upregulation of bone mineralization.* 
  • Up-regulating SIRT1 cell signaling pathway: SIRT1 protein promotes mitochondrial function, and its up-regulation inhibits cell death, promotes cell survival, and prolongs the lifespan of cells. Research1 indicates quercetin targets SIRT1 to regulate cellular senescence and multiple aging-related cellular processes.* 
  • Mitigating the effects of aging: Senescence-associated secretory phenotype (SASP) — a set of characteristics displayed by aging or senescent cells, includes the secretion of high levels of inflammatory cytokines, growth factors, immune modulators, and proteases. Quercetin helps limit the expression of senescent cell markers and inhibits the production of SASP.* 
  • Exerting benefits on the central nervous system: A study2 indicated that quercetin protects against age-related neurodegeneration.* Quercetin regulates the SIRT1/Nrf2/HO-1 cell signaling pathway, which counteracts and limits oxidative stress-mediated neuronal death.*
  • Limiting glutathione depletion: Quercetin enhances the activity of superoxide dismutase and catalase in the body, thereby inhibiting glutathione depletion.* By maintaining mitochondrial glutathione levels, quercetin protects against free radical damage to multiple cellular components.*  
  • Addressing immunosenescence: Quercetin has a direct beneficial effect on up-regulating the positive functions of immune cells, including inhibiting histamine and serotonin release from intestinal mast cells.* 
  • Inhibiting the activity of NF-κB signaling pathway: Quercetin inhibits3 the activity of the NF-κB signaling pathway, which protects cardiac tissues from damage caused by free radicals.* 

Although quercetin’s benefits and safety profile are well established, the poor natural bioavailability of quercetin in the gastrointestinal tract hinders its efficacy. Various pharmacological approaches, including nanotechnology, are aimed at enhancing quercetin’s solubility and subsequent absorption. 

Including Quercetin Benefits in Your Diet

Tesseract’s QuerciSorb® is an innovative quercetin formulation developed for optimal bioavailability and absorption. The proprietary CyLoc® – DexKey® nutrient delivery nanotechnology protects the integrity of quercetin molecules during their transit through the stomach and ensures targeted delivery.
