Metabolics mixed carotenoids are a combination formula containing alpha and beta-carotene, lycopene and zeaxanthin. Both alpha and beta-carotene can only be synthesised by plants and are only soluble in fats.
They are provitamins being safe biological precursors of Vitamin A (Retinol). They differ in the position of the double bond in their ring structure. Alpha carotene is found in fruits and vegetables such as leafy greens, avocados, broccoli and green beans. The more orange the vegetable, the greater the amount of beta-carotene, such as in carrots. Carotenoids are converted in the body to Vitamin A as a regulated process protecting the body from excessive Vitamin A intake that can be toxic.
Vitamin A is required for the normal maintenance of skin and vision and normal function of the immune system. It is also important for normal mucus membranes and plays an important part in the process of cell differentiation and iron metabolism.

The other carotenoids contained in this formula are lycopene and zeaxanthin. Lycopene is a bright red carotenoid found in tomatoes and other red fruits and vegetables. After it is ingested lycopene is incorporated into the lipid micelles in the small intestine allowing the fat-soluble carotenoid to be absorbed effectively. It is found predominantly in the liver, kidneys, adrenals and testes.
Zeaxanthin is also a carotenoid found in many vegetables and marigold flowers. Zeaxanthin is one of the two major components of the macular pigment of the retina and the lens of the eye.
