Vitamin A
Essential fat-soluble vitamin important for vision, immunity, and cell health; excess intake can cause toxicity, especially from supplements.
Vitamin A is a group of fat-soluble compounds that play key roles in vision, immune function, reproduction, and cellular communication. It is obtained from animal-derived retinol and plant-based carotenoids (provitamin A), with requirements varying by age, sex, and physiological state (e.g., pregnancy).
Benefits for vision, immunity, and cell health are well established; risks with excess intake, especially from preformed vitamin A, are well documented.
