In some cases, they can act as a precursor of Vitamin A, some act as antioxidants or have other important functions. The best known of the carotenoids is beta-carotene, but there are others, including alpha- and gamma-carotene, lutein, and lycopene.

No overdose can occur with beta-carotene, although if you take too much, your skin may turn slightly yellow-orange in color. Beta-carotene does not have the same effect as Vitamin A in the body and it is not harmful in larger amounts unless you cannot convert beta-carotene into Vitamin A. People with hypothyroidism often have this problem. It is important to take only natural beta-carotene or a natural carotenoid complex.
Betatene is the trade name for a type of caroteniod complex extracted from sea algae. It is used as an ingredient in various products by different manufacturers.
