It maintains certain amounts of phosphate and serum calcium, which allows the body to receive additional minerals. Vitamin D is also important for bone growth and development.
In cases of vitamin D deficiency, one is susceptible to hypocalcemic tetany, rickets (in children), osteomalacia and osteoporosis (adults). This deficiency can also result in misshapen, thin, or weak bones.

1. stratum corneum: 20-30, horny layers (most superficial layer of the epidermis)
2. stratum lucidum: only in thicker layers of skin like palms of hands and feet
3. stratum granulosum: thin layer of cells in the epidermis 
4. stratum spinosum: most layers; location of keratinocyte 
5. stratum basale: actively mitotic stems cells; as cells age they become part of superficial layers

Vitamin D is synthesized by the skin. When the skin comes in contact with sunlight, the vitamins go through the blood stream to your liver and kidney and then it becomes activated (calcitriol) and it's circulated to all the bones in your body.

Yes, fair skinned people absorb less ultraviolet-B (UVB) becuase they don't have enough melanin in their skin than those with darker skin. Therefore, people with darker skin tones require at least five times longer sun exposure to make the same amount of vitamin D as someone with fair skin.

People closest to the equator is going to be darker and more intense deep color. Melanin at the poles solar rays are weaker sunlight was available to collect vitamin D.

Anyone can get skin cancer regardless of their race, although, cases of melanoma in caucasions is higher studies have proven. Most skin cancers are associated with ultraviolet radiation from the sun or from tanning beds, says Dr. Perez. Darker skin produces more of the pigment called melanin that does help protect skin — but only to a certain extent. People of color can still get sunburned, and they can also develop skin cancer from UV damage. Anyone can get skin cancer regardless of their skin color.
