Beta carotene is the precursor to vitamin A. The body converts beta carotene into vitamin A.

The retinoids (vitamin A) and the carotenoids ( precursors to vitamin A) are closely related. Beta carotene,one of many carotenoids, is easily converted into vitamin A and has been researched more than the other carotenoids.

Beta carotene may be preferable because unlike vitamin A it is non toxic. Vitamin A is stored in the liver and when taken in high doses over time (1000,000IU for months) it may become toxic. Beta carotene is non-toxic and does not pose the same risks to the liver that vitmain A does.

Beta carotene is an immune system booster. It may be helpful in reducing the bodys susceptability to infection thereby preventing sore throats, coldsand flu. Beta Carotene may be helpful in preventing heart disease by preventing the oxidation of LDL.

Increased levels of beta carotene have been associated with lower risks of cancer. Beta carotene may be helpful in HIV infection by increasing white blood cells and CD4 cells, both are important in immune function. Beta carotene may be a treatment for skin disorders such as severe dry skin, acne (even severe acne not helped by medical treatment), eczema and psoriasis.
