Dark skinned people may be less efficient at making vitamin D because melanin in the skin hinders vitamin D synthesis however, a recent study has found novel evidence that low vitamin D levels among Africans may be due to other reasons.

Vitamin D The human body can synthesize vitamin D when skin is exposed to ultraviolet radiation from the sun.

Some, such as vitamin D, have hormone like functions as regulators of mineral metabolism, or regulators of cell and tissue growth and differentiation (such as some forms of vitamin A).

It's very destructive, but it also catalyzes the production of vitamin D in the skin, vitamin D being a molecule that we very much need for our strong bones, the health of our immune system, and myriad other important functions in our bodies.

Retinyl palmitate is an antioxidant and a source of vitamin A added to low fat milk to replace the vitamin content lost through the removal of milk fat.
