Vitamin C Bioflavonoids

Ingredient research · Annatto

Annatto is a red-orange pigment-rich preparation from the seeds of Bixa orellana, best established as a food colorant rather than a nutrient supplement. Although its carotenoid constituents, chiefly bixin and norbixin, prompt interest in antioxidant and metabolic effects, meaningful human health benefits from annatto itself remain unestablished.

Ingredient research · Grapefruit Extract

Grapefruit Extract is a loosely defined supplement made from the fruit, peel, or seeds, so its flavonoid and furanocoumarin content can vary widely. It is mainly taken for proposed antioxidant, metabolic, or antimicrobial effects, but no broad benefit is well established; some preparations may also share grapefruit’s important interactions with certain medicines.

Ingredient research · Lemon

Lemon is a citrus fruit used in supplements as juice or fruit powder, peel extract, or essential oil—preparations that differ substantially in composition. Its vitamin C, citric acid, and flavonoids motivate interest in antioxidant, cardiovascular, and urinary health, but practical benefits depend heavily on the preparation.

Ingredient research · Tangerine Seed

Tangerine Seed is a whole citrus seed ingredient, sometimes used as a powder, oil, or extract for its fatty acids and plant compounds such as limonoids. Interest centers on possible antioxidant and metabolic effects, but it has little established supplementation use and no clearly demonstrated human benefit.
