Beta-carotene (β-carotene) is a red-orange pigment found in plants and fruits, particularly carrots and other colorful vegetables. It is a carotenoid and is a precursor to Vitamin A. The human body converts beta-carotene into retinol, which is a form of Vitamin A. This conversion primarily occurs in the liver. Vitamins C, D, and K have different precursors or are synthesized differently (e.g., Vitamin D synthesized in the skin upon sunlight exposure).

Beta-carotene is a carotenoid pigment found in plants that the body can convert into Vitamin A.

Vitamin A is essential for vision, immune function, reproduction, and cell growth. Other carotenoids like alpha-carotene and beta-cryptoxanthin can also be converted to Vitamin A, but beta-carotene is the most efficient precursor. Vitamin C is an ascorbic acid. Vitamin D is synthesized in the skin from cholesterol derivatives upon UV exposure. Vitamin K is involved in blood clotting and bone metabolism and is synthesized by gut bacteria or obtained from leafy greens.
