Vitamin A

Vitamin A is a fat-soluble vitamin that includes a group of compounds such as retinol, retinoic acid, retinal, and provitamins like beta-carotene. It plays a crucial role in various physiological functions in the body, including vision, immune system health, skin integrity, and hair health.

Vitamin A is essential for maintaining healthy vision, particularly in low-light conditions. It also supports the normal function of the immune system, helps maintain the health of the skin and mucous membranes, and plays a role in cell differentiation and growth.
