Research-driven nutrients and strategies that support longevity.

Introduction

As we age, the body undergoes natural biological changes that affect cellular repair, circulation, immune function, and overall vitality. Research over the past several decades has shown that certain nutrients can help support these systems and promote healthier aging.

Science-based nutritional supplementation has emerged as an important strategy for maintaining cardiovascular health, protecting vision, supporting cognitive function, and strengthening immune resilience. When properly formulated, these nutrients can help the body maintain normal physiological balance as we grow older.

For more than two decades, Longevinex® has focused on the scientific study of longevity-supporting nutrients, particularly transresveratrol, one of the most researched plant compounds associated with healthy aging. Rather than following short-term supplement trends, Longevinex formulas are designed around carefully studied biological mechanisms that influence circulation, cellular defense systems, and metabolic stability.

Since its introduction in 2004, Longevinex® has become widely recognized for its research-driven approach to resveratrol supplementation. The flagship formulas Longevinex® and Advantage™ were developed to support cardiovascular health, cellular protection, and long-term vitality while also providing nutritional support for individuals concerned about age-related vision changes, including macular degeneration.

Alongside these resveratrol formulas, complementary products including Garlinex™, Garligest™, and T-Cell Zinc™ were developed to address additional aspects of healthy aging, including circulation, digestion, and immune resilience. Together, these formulas form a coordinated nutritional system designed to support multiple biological pathways involved in long-term health.

Longevinex®: The Foundation of the Formula System
A Patented Nutraceutical Matrix

At the center of the Longevinex® system is transresveratrol, a naturally occurring polyphenol widely studied for its potential role in supporting healthy aging. Transresveratrol is found in plants such as Japanese knotweed (Polygonum cuspidatum), one of the richest natural sources of this compound.

However, resveratrol presents several formulation challenges. It is sensitive to light, oxygen, and heat, which can reduce stability and biological activity if not properly protected. For this reason, Longevinex® was developed using a patented nutraceutical matrix designed to enhance the stability, absorption, and bioavailability of transresveratrol.

This formulation approach has been described in a U.S. patent, which outlines methods for improving the molecular stability of resveratrol and supporting its effective delivery within the body.

Stabilized Transresveratrol

Each capsule of Longevinex® provides 100 mg of transresveratrol derived from Japanese knotweed. The patented formulation helps protect this sensitive polyphenol while supporting its absorption and biological activity.

Supporting Nutrients Within the Matrix

In addition to transresveratrol, the Longevinex® formulation includes several complementary nutrients designed to support cellular function and metabolic balance.

Fisetin

Fisetin is a naturally occurring plant polyphenol found in foods such as strawberries. It has attracted scientific interest for its potential role in cellular protection and research exploring age-related cellular processes.

Quercetin

Quercetin is a flavonoid widely studied for its antioxidant properties and its role in supporting vascular health and cellular defense systems.

Benfotiamine (Vitamin B1)

Benfotiamine is a fat-soluble form of thiamine that supports glucose metabolism and nerve health.

Nucleotides

Nucleotides are fundamental components of DNA and RNA. During periods of cellular repair and regeneration, the body’s supply of these building blocks may become limited. Supplemental nucleotides may help support normal cellular repair processes.

Beta-Cyclodextrin

Beta-cyclodextrin is included to support the solubility of resveratrol and help protect sensitive polyphenols within the formula.

A System Designed for Cellular Support

Together, these ingredients form a coordinated formulation designed to support several biological systems associated with healthy aging, including:

• vascular function and circulation
• cellular protection against oxidative stress
• metabolic balance
• normal cellular repair processes

These mechanisms help explain why transresveratrol and related polyphenols continue to attract attention in longevity research.

Nutritional Support for Vision Health

Healthy circulation plays an important role in maintaining the delicate blood supply that nourishes retinal tissue. Because transresveratrol supports vascular function, Longevinex® has often been used by individuals seeking nutritional support for maintaining normal vision and retinal health as they age.

Advantage™: Enhanced Longevity & Vitality Support

For individuals seeking broader nutritional support for healthy aging, Advantage™ builds upon the scientific foundation of Longevinex® by incorporating additional nutrients that support vision, connective tissue, and cellular resilience.

Each capsule contains carefully selected compounds designed to complement transresveratrol’s role in supporting circulation, cellular protection, and metabolic balance.

Key Nutrients in Advantage™

Hyaluronan (Hyaluronic Acid)

Hyaluronan is a naturally occurring component of connective tissue found in the skin, joints, and eyes. It plays an important role in maintaining tissue hydration, elasticity, and structural integrity. Supplemental hyaluronan may help support joint comfort, skin hydration, and healthy connective tissue as the body ages.

Lutein and Zeaxanthin

These carotenoids are concentrated in the macula of the eye, where they help filter blue light and support the health of retinal tissue. Adequate intake of lutein and zeaxanthin has been associated with supporting visual performance and maintaining normal macular health as individuals age.

When combined with the circulation-supporting effects of transresveratrol, these nutrients provide additional nutritional support for individuals concerned about age-related vision changes.

A Complement to Longevinex®

Together, Longevinex® and Advantage™ provide a coordinated approach to nutritional longevity support. While transresveratrol helps support cellular defense systems and vascular health, the additional nutrients in Advantage™ contribute targeted support for connective tissue integrity and visual health.

This complementary design reflects the broader philosophy behind Longevinex formulas — supporting multiple biological systems involved in healthy aging rather than relying on a single nutrient approach.

Garlinex™: Enzyme-Activated Allicin for Circulation and Cellular Defense

Garlic has been used for centuries as both a food and a medicinal plant. Modern research has identified allicin as one of garlic’s most biologically active compounds, responsible for many of its circulation-supporting and antimicrobial properties.

However, producing meaningful amounts of allicin from garlic supplements is technically challenging. Allicin forms only when specific garlic enzymes are activated, and many garlic preparations fail to generate significant levels of this compound.

Garlinex™ was developed to address this challenge using a patented Alkemy™ buffered garlic delivery system designed to generate enzyme-activated allicin under physiological conditions.

Enzyme-Activated Allicin

When the garlic compounds within Garlinex™ are activated, they produce allicin, a sulfur-containing molecule studied for several important biological effects.

Allicin has been investigated for its ability to:

• support healthy blood circulation
• help maintain blood pressure within the normal range
• provide antimicrobial and germ-fighting activity

Unlike some antimicrobial agents, allicin has been observed to exert germ-fighting activity without contributing to microbial resistance.

Support for Vascular Function

Garlinex™ may also support vascular health through the temporary production of signaling molecules such as hydrogen sulfide and nitric oxide, both of which are known to help relax and widen blood vessels.

These mechanisms can contribute to improved circulation and healthy vascular function.

Activation of Cellular Defense Pathways

Compounds within garlic have also been studied for their ability to activate the Nrf2 genetic pathway, an important regulatory system that stimulates the body’s production of natural internal antioxidants such as:

• glutathione
• catalase
• superoxide dismutase

These protective enzymes help the body manage oxidative stress and maintain cellular resilience.

Complementary Botanical Ingredients

Garlinex™ also incorporates several complementary botanical compounds traditionally associated with antimicrobial and digestive support.

These include extracts from:

• allspice
• clove
• ginger

These ingredients are combined within a base of IP6 rice bran extract, contributing additional antioxidant support.

The formula is packaged to protect stability and maintain product freshness throughout its shelf life.

Garligest™: Supporting Healthy Digestion as We Age

Targeted Nutritional Support for Digestive Function

Healthy digestion plays an essential role in overall well-being. As individuals age, the body’s natural production of stomach acid and digestive secretions may gradually decline. This change can make it more difficult to properly break down food, particularly fats and proteins, and may contribute to symptoms such as bloating, gas, and digestive discomfort.

Garligest™ was developed to help support normal digestive processes by providing nutrients that assist stomach acid balance, bile flow, and nutrient breakdown.

Supporting Stomach Acid Balance

One of the key ingredients in Garligest™ is betaine hydrochloride, which helps support the natural acidity of the stomach. Adequate stomach acid plays an important role in the digestion of proteins and in the body’s defense against unwanted microbes that may enter through food.

Buffered garlic included in the formula has also been studied for its ability to support microbial balance in the digestive system, helping maintain a healthier digestive environment.

Supporting Bile Flow and Fat Digestion

Efficient digestion of fats requires healthy bile production and flow from the liver and gallbladder. Garligest™ includes several ingredients traditionally associated with supporting this process.

These include:

• Taurine – involved in bile salt formation
• Apple pectin – a soluble fiber that supports digestive balance
• IP6 rice bran extract – known for antioxidant and metabolic support
• Vitamin C – contributes to overall digestive and metabolic health

Together, these ingredients help support the body’s natural ability to process fats and oils efficiently.

Enzyme Support for Dairy Digestion

For individuals who experience difficulty digesting dairy products, Garligest™ includes lactase, the enzyme responsible for breaking down lactose. This can help support normal digestion of dairy-containing foods.

Botanical Support for Digestive Comfort

The formula also contains fennel powder, a botanical traditionally used to support digestive comfort and help reduce gas formation.

A Comprehensive Digestive Support Formula

By combining stomach acid support, bile flow nutrients, digestive enzymes, and botanical ingredients, Garligest™ provides a multi-faceted approach to supporting digestive function.

Healthy digestion supports more than comfort—it also plays a crucial role in nutrient absorption, metabolic balance, and overall vitality.

T-Cell Zinc™: Essential Immune Support

Supporting the Body’s Immune Defense System

A strong immune system depends on the proper function of specialized white blood cells known as T-cells, which play a central role in identifying and responding to potential threats to the body.

These immune-regulating cells are produced and matured in the thymus gland, an organ located behind the breastbone. One of the most important nutrients required for healthy thymus function is the trace mineral zinc.

Zinc deficiency has been associated with reduced thymus activity and weakened immune responsiveness. As individuals age, zinc status can decline, which may contribute to a gradual reduction in immune efficiency.

Zinc and the Thymus Gland

Zinc plays an important role in supporting the thymus gland and the production of T-cells that help regulate immune responses. Adequate zinc intake helps maintain normal immune signaling and supports the body’s ability to respond effectively to infections.

Research has shown that insufficient zinc intake can impair immune function, while restoring adequate zinc levels helps support normal immune activity.

Supporting Immune Resilience

T-Cell Zinc™ provides 12 mg of highly bioavailable zinc citrate, along with complementary nutrients that help support zinc utilization within the body.

These include:

• Selenium – supports antioxidant defense and assists with zinc metabolism

• Vitamin B6 – helps support zinc absorption and immune regulation

• Vitamin C – contributes additional antioxidant and immune support

• Royal jelly – a nutrient-rich natural compound associated with cellular vitality

• Beta-cyclodextrin – included to support nutrient delivery and stability

Together, these ingredients help support the body’s natural immune defenses and contribute to overall resilience as the body ages.

Zinc and Healthy Aging

Zinc plays roles beyond immune support. Adequate zinc levels are also associated with:

• healthy skin, hair, and nails
• cognitive function
• metabolic balance
• cellular repair processes

Research on exceptionally long-lived individuals has also noted that many maintain strong immune function well into advanced age, highlighting the importance of nutrients that support immune regulation.

Complementing the Longevinex® System

When used alongside Longevinex® resveratrol formulas, T-Cell Zinc™ supports another critical component of healthy aging: immune resilience.

While transresveratrol supports cellular protection and vascular health, zinc contributes to the proper function of immune cells responsible for protecting the body against environmental stressors.

Together, these nutrients support multiple biological systems involved in maintaining long-term health.

Science & Design Behind the Longevinex® Formulas

The Longevinex® family of formulas was developed with a systems-based approach to supporting healthy aging. Rather than focusing on a single nutrient, each formula was designed to support one or more biological processes associated with long-term health.
