Vitamin D is a prohormone that helps in the absorption of calcium from the gut. Deficiency of vitamin D leads to many threats.

Do all humans have melanin?

Special skin cells called melanocytes make melanin. Everyone has the same number of melanocytes, but some people make more melanin than others. If those cells make just a little bit of melanin, your hair, skin and the iris of your eyes can be very light.
