There are two primary forms of vitamin A: retinoids, which are found in animal products, and carotenoids, which are found in plant-based foods.

Why Vitamin A is a Must-Have for a Healthy Immune System

Vitamin A is critical for immune function, helping to maintain the integrity and function of the skin and mucous membranes that line the respiratory, gastrointestinal, and urogenital tracts. Low vitamin A levels are associated with an increased risk of infections, especially in children. Vitamin A deficiency can also impact the ability to respond to vaccines effectively.

From Skin to Bones: The Comprehensive Effects of Vitamin A on the Body

Vitamin A plays a critical role in maintaining healthy skin and mucous membranes throughout the body. It also helps support the formation and maintenance of bones and teeth. Vitamin A deficiency can lead to issues such as dry skin, acne, and a weakened immune system. It can also impact the development of fetal bones and teeth.
