Vitamins are essential organic compounds which are needed in small quantities for our bodies to function properly.

We need to ingest certain amounts of vitamins daily, usually through our diet, because our bodies produce insufficient amounts of them, or they don’t produce them at all. Children and older adults especially have to make sure they are getting enough of them.

There are 13 vitamins overall, and they all have different functions. Vitamins are classified into water-soluble (vitamin B complex and vitamin C) or fat-soluble (vitamins A, D, E, and K).
