VITAMINS are grouped into water soluble and fat soluble vitamins.
The water soluble vitamins are Vit C, B1, B2, B3, B5, B6, B12, biotin, and folic acid.
These vitamins need to be supplied to the body via food and, if necessary, supplements on a daily basis since the body doesn’t store them. Whatever the body doesn’t need on any one day, it excretes it in the urine.
Vit B12 is the exception. It can be stored in the liver for several years. Thus, a Vit B12 deficiency may not develop after years of a diet deficient in this vitamin.
