Vitamin D is a type of secosteroid and its synthesis in the epidermis is dependent on sun exposure (UVB radiation). This vitamin is key to have normal growth and to properly absorb calcium, magnesium, and phosphate.
Melanin, on the other end, is a natural pigment also found on skin that is responsible for our skin color and protects our bodies from UVB radiation damage. On people with darker skin tones, the higher levels of melanin hinder Vitamin D synthesis since it acts as a natural protector against the sun.
For this reason, light-skinned people (low melanin levels, high vitamin D synthesis) live better in the poles, where they can absorb limited UV because of the weaker sunlight. Dark-skinned people are better off living in regions with the stronger sunlight, like the tropics.
