High-Potency Retinyl Form

Benefits and Features

• 7,500 mcg
• 25,000 IU
• Facilitating the support of visual and immune systems effectively

Detail Overview

Vitamin A, provided in the forms of retinyl palmitate and fish liver oil, is an indispensable nutrient with wide-ranging benefits for bodily health. Retinyl palmitate is a chemically stabilized ester form of retinol, which is an active form of vitamin A. This form is particularly beneficial as it is more stable and less susceptible to oxidation, making it a preferred choice in dietary supplements for ensuring consistent and reliable dosage. It is easily absorbed and utilized by the body, facilitating the support of visual and immune systems effectively.

Vitamin A's role in maintaining vision is paramount; it is crucial for the proper functioning of the retina, particularly in converting light into neural signals which enable vision in low-light conditions. This function is mediated by retinal, a specific form of vitamin A that interacts with protein opsin to form rhodopsin, a molecule integral to the vision process in dim lighting. Beyond its vision-enhancing capabilities, vitamin A is vital for the growth and development of cells lining the eyes. By supplementing with retinyl palmitate or fish liver oil, individuals can support their ocular health robustly, preserving and enhancing vision functionality.

The immune-enhancing properties of vitamin A are equally critical. It supports immune health by maintaining mucosal surfaces by helping in the production and function of white blood cells, which play a crucial role in capturing and clearing pathogens from the bloodstream and lymphatic system. This includes the lining of the airways and digestive tract, which are the body's first line of defense against disease-causing organisms. Vitamin A also influences the function of immune cells, including T-cells, B-cells, and cytokines, which coordinate the body's response to pathogens and inflammation. Moreover, it is integral to the skin's defense system, promoting the turnover of skin cells and maintaining the integrity of skin that serves as a barrier against environmental threats. By fostering these barriers and cellular functions, vitamin A plays an essential role in defending the body against infections and maintaining overall immune resilience.

SUPPLEMENT FACTS

Bioavailable, micronized form

Benefits and Features

DHEA is the most abundant androgen produced by the adrenal glands and supports many functions including:

• Healthy immune cell function
• Emotional wellbeing
• May promote a healthy ratio of lean muscle to fat mass

Detail Overview

Pure DHEA that has been micronized to very small particle sizes to facilitate absorption is provided in vegetarian capsules. Levels of this adrenal hormone begin to decline by your 30s. Supplementation may support immune function, metabolic health, and emotional well-being.

Supports insulin function and glucose regulation

Benefits and Features

D-chiro-inositol has been studied for its role in supporting healthy insulin and glucose metabolism, maintaining normal lipid profiles, and promoting healthy cardiovascular and ovarian function.^†

Detail Overview

This stereoisomer of inositol is a critical second messenger mediating cellular responses to insulin. Embedded in cell membranes, D-chiro-inositol is part of a glycosyl phosphatidylinositol complex that is hydrolyzed into two bioactive molecules upon exposure to insulin. These molecules regulate glucose disposal by activating pathways in which glucose is either converted to glycogen for storage or oxidatively metabolized to produce energy.^† Studies show D-chiro-inositol is involved in proper insulin and glucose metabolism and may have a role in maintaining normal lipid profiles, cardiovascular function, and ovarian function.^† It may also help regulate inflammatory stress and modulate serotonin activity.^† Derived from carob pods, D-Chiro-Inositol is recommended to support normal insulin function and blood sugar metabolism.

Supports gut barrier health

Benefits and Features

• Helps protect your stomach and small intestine lining.
• Promotes digestive comfort.

Detail Overview

Zinc carnosine has been shown in multiple clinical trials to help protect the stomach lining and promote gastrointestinal comfort.^† Studies show zinc carnosine promotes healthy mucus secretion, exerts antioxidant properties, and modulates cytokine expression, thus helping protect the stomach and small intestine.^† L-glutamine promotes small intestinal cell function and mucosal integrity to further support gastric function and protect tissues.^† 

Research 

This patented, 1:1 chelate of zinc and l-carnosine provides a unique configuration that accounts for this compound's unique functions in the GI tract. Zinc-carnosine has a slow dissociation rate and adheres to the stomach lining, allowing for prolonged protection.¹ When zinc and carnosine are separated, they provide synergistic antioxidant protection, support the stomach's mucosal defenses, buffer gastric acid, and maintain healthy cytokine release.² According to studies, this combination is more effective than either ingredient alone in maintaining the integrity of the gastric lining.³ A Japanese multi-center, double-blind study involving 299 subjects found improvements in objective and subjective parameters of normal gastric health and repair, particularly after 8 weeks of daily supplementation.⁴ Seven additional clinical trials involving over 550 volunteers yielded similar results. In vitro and in vivo studies show that zinc-carnosine promotes cellular repair in the intestine by promoting healthy cell reproduction and villous function.⁵ Zinc-carnosine maintained healthy gut barrier function in a double-blind, randomized, crossover trial.⁶ This zinc-carnosine combination has been extensively researched and used in Japan, and it has an excellent safety profile.
