How Vitamins Work

Taking vitamin D
Vitamin D is another simple nolecule that is incredibly important. We actually have the ability to produce vitamin D in our skin. To do it we have to have regular explosure to the sun's ultraviolet rays. Without enough sun exposure, people get different ailments depending on their age. Modern humans can often spend days at a time indoors, especially in the winter, with very little sun exposure. So we add vitamin D to milk and other foods.

A damaged gene?
You have probably noticed that dogs have no need for citrus fruit. They, like most animals, produce their own vitamin C molecules. Human beings lost this ability. Apparently, at some point, the vitamin C gene was damaged. We inherited this damaged gene from our gene, so humans must get vitamin C from food. We still have a lot to learn about vitamins. Many people believe that if you take massive amounts of vatamin C, there is a health benefit. Is this true? Recent research suggests that it probably is not true. There may be a few other vitamins lurking out there waiting to be discovered.
