Vitamin A Part 2

Vitamin A may also be added to the diet by taking a dietary supplement; however, those taking vitamin A supplements should proceed with caution.

Side effects of too much vitamin A in the diet include hair loss, enlarged liver and spleen, anemia, and joint pain. Thus, it is thought safer for individuals to get the vitamin A they need from a well-balanced diet that includes foods rich in beta-carotenes.

Beta-carotenes are converted to vitamin A by the body as needed, and the only toxic side effect of consuming massive amounts of this substance is a yellowing of the skin, which subsides immediately upon reducing the dosage.

Vitamin A is a proven success in the fight against wrinkles and acne. Vitamin A derivatives such as Retin-A (applied topically) and Accutane (taken orally) are often effective treatments for acne, psoriasis, and other skin disorders.

The Recommended Dietary Allowance (RDA) of vitamin A is 5,000 International Units (IU) for adult men, and 4,000 IU for adult women (6,500 IU if nursing), though dietary supplements can contain up to 10,000 IU of vitamin A.
