Question

WHAT IS THE IMPORTANCE OF THE VITAMIN A ?

Answer 1

Vitamin A is a fat-soluble vitamin that is naturally present in many foods. Vitamin A is important for normal vision, the immune system, and reproduction. Vitamin A also helps the heart, lungs, kidneys, and other organs work properly.

The best form: Two forms of vitamin A are available in the human diet: preformed vitamin A (retinol and its esterified form, retinyl ester) and provitamin A carotenoids [1-5].


Is it safe: The tolerable upper intake levels of a supplement are the highest amount that most people can take safely. Higher doses might be used to treat vitamin A deficiencies. But you should never take more unless a doctor says so. * There is no upper limit for vitamin A from beta-carotene.

Can u take vitamin A every day: If you take vitamin A for its antioxidant properties, keep in mind that the supplement might not offer the same benefits as naturally occurring antioxidants in food. The recommended daily amount of vitamin A is 900 micrograms (mcg) for adult men and 700 mcg for adult women.
