Ingredient research · Vitamin B6

Vitamin B6 is an essential nutrient that helps enzymes process amino acids and supports neurotransmitter, hemoglobin, and immune function. Supplementation reliably corrects deficiency and can reduce nausea during pregnancy; outside these uses, it is most relevant when intake or absorption is inadequate.

• Supports depressive-symptom measures in premenopausal women with hormone-related contexts.

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 · L-Tyrosine

L-Tyrosine is an amino acid the body uses to make dopamine, norepinephrine, and thyroid hormones. Supplementation may help preserve attention, working memory, and mental performance during acute stressors such as sleep loss or cold exposure, but it is not a reliably effective everyday cognitive or mood enhancer.

• Supports cycling endurance during exercise in the heat.

Ingredient research · Mucuna Pruriens

Mucuna Pruriens is a tropical legume whose seeds naturally contain levodopa, a direct precursor to dopamine. Extracts can improve movement symptoms in Parkinson’s disease and are also taken with the aim of supporting mood, libido, or fertility, but their effects and drug-like interactions depend heavily on levodopa content.

Ingredient research · Rhodiola rosea root extract

Rhodiola rosea root extract is a botanical “adaptogen” used to make physical and mental strain feel more manageable. It may modestly reduce fatigue, stress-related exhaustion, or perceived effort during demanding periods, but effects depend on the extract, and distinct benefits for mood, cognition, and exercise performance remain uncertain.

Ingredient research · Grape Seed Extract

Grape Seed Extract is a concentrated source of proanthocyanidins, polyphenols that influence antioxidant defenses and blood-vessel function. Supplementation may modestly support circulation and healthy blood pressure, with possible relevance to swelling and skin health; it is distinct from resveratrol-rich grape products and their associated claims.

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.
