The pigment melanin, which is more prevalent in people with darker skin, reduces your body’s ability to make vitamin D in response to sunlight exposure. Essentially, this means that people who have pale skin produce vitamin D more quickly than people with darker skin.

What role does vitamin D play in the evolution of skin color?

The vitamin D–folate paradigm proposes that skin pigmentation evolved as a balancing mechanism to maintain levels of two key vitamins in human health: vitamin D and folate. In maintaining levels of these vitamins, the roles of these nutrients during reproduction would be preserved.

What is the relationship between skin color and vitamin D?

Circulating vitamin D concentrations differ by skin color: Individuals with darker skin produce less vitamin D with the same amount of sunlight exposure than individuals with lighter skin color [10,12].

Would a darker skinned person have a harder or an easier time making vitamin D?

Vitamin D synthesis is highly dependent on the concentration of melanin in the skin as melanin absorbs and scatters UVR-B, resulting in a less efficient conversion of 7-dehydrocholesterol to previtamin D3[3]. Therefore, dark-skinned individuals will experience slower vitamin D synthesis than light-skinned ones.

Does vitamin D increase melanin?

Melanin has photoprotective action and protects the skin from harmful effects of ultraviolet radiations. High melanin level inhibits the production of vitamin D in the skin. Vitamin D is a prohormone that helps in the absorption of calcium from the gut. Deficiency of vitamin D leads to many threats.
