Your question: Do darker skin tones need more vitamin D?

Melanin is the pigment that provides skin color, and individuals with darker skin have more of it than those with lighter skin. Having more melanin reduces your ability to synthesize vitamin D from the sun, resulting in lower 25-hydroxyvitamin D levels, according to the ODS.

Does skin color affect vitamin D levels?

Studies have shown that individuals with darker skin pigmentation require longer or more intense ultraviolet radiation exposure to synthesize sufficient levels of vitamin D. In other words, if you have darker skin, you tend to make less vitamin D in the sun than people with lighter skin.

Can dark skin people get vitamin D from the sun?

Among Americans of color, the vitamin D deficiency rate jumps to 70%. Pigment in persons with darker skin blocks sunlight absorption, a key process for vitamin D production.

Does lighter skin absorb more vitamin D?

Vitamin D production depends on exposure to sunlight. Humans living at latitudes far from the equator developed light skin in order to help absorb more vitamin D. People with light (type II) skin can produce previtamin D3 in their skin at rates 5–10 times faster than dark-skinned (type V) people.

Does having more melanin and thus darker skin color help or hurt my folate levels?

A higher level of melanin allows normal folate synthesis by absorbing the UV radiation, and can allow for normal gestation and fetal development. Essentially, evolution allowed for a feature (darker skin) that would allow healthy and successful reproduction.

Why do dark people have vitamin D deficiency?

The body naturally produces vitamin D in response to the skin’s exposure to sunlight. People with darker skin pigmentation, like African-Americans, are at greater risk for vitamin D deficiency or insufficiency because the higher presence of melanin reduces the body’s ability to produce vitamin D.

Why is vitamin D important for dark skin?

As necessary as melanin is for protection against the effects of UV radiation, it also acts as blocker preventing dark-skinned people from producing the amount of vitamin D required for their wellbeing.
