Ingredient research · Vitamin A

Vitamin A is an essential fat-soluble nutrient that enables normal vision, especially in dim light, and helps maintain immune defenses, skin and other epithelial tissues, growth, and reproduction. Supplementation can prevent or correct deficiency when intake or absorption is inadequate, benefiting visual, immune, and developmental health.

• Supports maternal and breast-milk vitamin A status, particularly where baseline stores are low.
• Supports hemoglobin response in some anemic or vitamin A-deficient populations, including when added to iron and folate.
• Supports reducing bacterial-vaginosis incidence and prevalence during pregnancy and postpartum follow-up in a studied deficient setting.

Ingredient research · Vitamin C

Vitamin C is an essential water-soluble nutrient that supports collagen production, antioxidant defenses, and the normal function of immune cells. Supplementation reliably prevents or corrects deficiency, can improve absorption of plant-based iron, and may modestly shorten the duration of common colds when taken regularly.

• Supports lower common-cold risk during brief periods of severe physical exercise or cold stress.
• Supports circulating Vitamin C status across studied healthy and clinical populations.
• Supports short-term blood-pressure and endothelial-function outcomes in studied adults.
• Supports fasting-glucose and HbA1c outcomes in adults with type 2 diabetes.

Ingredient research · Vitamin E

Vitamin E is an essential fat-soluble antioxidant that protects cell membranes from oxidative damage and supports normal immune and nerve function. Supplementation is most useful for preventing or correcting deficiency, particularly when fat absorption is impaired; routine use has not shown broad protection against cardiovascular disease or cancer.

• Supports improvement in liver histology in adults without diabetes who have biopsy-confirmed nonalcoholic steatohepatitis.
• Supports lower CRP and malondialdehyde in studied adult populations, including people receiving hemodialysis.
• Supports short-term improvements in fasting glucose and HbA1c in adults with type 2 diabetes.

Ingredient research · Zinc

Zinc is an essential mineral needed for hundreds of enzymes, DNA and protein synthesis, immune defense, wound healing, and normal growth. Supplementation corrects low zinc status and helps restore these functions; certain zinc lozenges may also modestly shorten a common cold when used early, though this benefit depends on the formulation.

Ingredient research · Selenium

Selenium is an essential trace mineral used to make antioxidant enzymes and regulate thyroid hormone activity, linking adequate intake to thyroid, immune, and reproductive function. Supplementation can correct low selenium status, but more is not necessarily better because excessive intake can be toxic.

• Supports selected thyroid-autoantibody and TSH markers in studied people with autoimmune thyroiditis.
• Supports selected antioxidant-defense biomarkers in studied metabolic, cardiovascular, and selenium-status populations.
• Supports depression-symptom measures across a small selenium-specific randomized evidence base.

Ingredient research · Copper

Copper is an essential trace mineral used by enzymes that support iron metabolism, connective-tissue formation, energy production, antioxidant defense, and nervous and immune function. Supplementation can correct low copper status and related anemia or neurologic problems, but extra copper offers no established benefit when intake and status are adequate.

Ingredient research · L-Cysteine Hydrochloride

L-Cysteine Hydrochloride is a salt form of the sulfur-containing amino acid cysteine, which contributes to protein synthesis and production of the antioxidant glutathione. It is used to supply cysteine in nutritional and medical formulations, but the hydrochloride form has no well-established health advantage over other cysteine sources.

Ingredient research · Quercetin

Quercetin is a plant flavonoid with antioxidant and inflammation-modulating activity, commonly taken for immune, cardiovascular, and allergy-related support. Human benefits appear modest and context-dependent: it may slightly improve blood pressure and some inflammatory markers, while its usefulness for preventing infections or relieving allergy symptoms remains uncertain.

• Supports LDL and total-cholesterol markers in adults with metabolic disorders.
• Supports selected insulin-sensitivity and adipokine markers in women with polycystic ovary syndrome.
• Supports disease-activity and joint-symptom measures in women with rheumatoid arthritis.
• Supports neuromuscular recovery and selected muscle-damage markers after eccentric exercise.

Ingredient research · Green Tea Leaf Extract

Green Tea Leaf Extract concentrates tea catechins, often alongside caffeine, and is mainly used for modest support of weight management and cardiometabolic health through effects on energy expenditure and fat metabolism. Its composition varies, and concentrated extracts are not equivalent to drinking green tea; some products have been linked to liver injury.

Ingredient research · CoQ10

CoQ10 is a vitamin-like compound that helps mitochondria make cellular energy and also acts as an antioxidant. Supplements can modestly improve symptoms and exercise capacity in some people with heart failure, and may help prevent migraines or ease statin-associated muscle symptoms, though these uses are less consistent.

• Supports fatigue-related symptom outcomes.
• Supports migraine frequency, duration, and severity outcomes.
• Supports blood-glucose and insulin-related markers.
• Supports heart-failure functional-class and hospitalization outcomes.
• Supports sperm count, motility, morphology, and fertility-related outcomes.
