Vitamin A

Vitamin A is family of fat-soluble vitamins. Retinol is one of the most usable forms of vitamin A and is found in foods such as fish, liver, milk and eggs. Retinol (preformed vitamin A) can be converted to retinal and retinoic acid, other forms of the vitamin A family. Some plant foods such as carrots, kale, broccoli and spinach contain provitamin A carotenoids which the body can convert to vitamin A. Beta-carotene is a provitamin A carotenoid which is more efficiently converted to retinol than other carotenoids . Vitamin A is also a potent antioxidant. Studies have confirmed that it can help treat or prevent cancer and that it improves resistance to infection. It is essential for healthy vision, skin, teeth, bone growth, cell reproduction, wound healing, immunity and other crucial bodily functions.
