Vitamins are a group of substances that are needed for normal cell function, growth, and development.
There are 13 essential vitamins. This means that these vitamins are required for the body to work properly. They are:
Vitamin A
Vitamin C
Vitamin D
Vitamin E
Vitamin K
Vitamin B1 (thiamine)
Vitamin B2 (riboflavin)
Vitamin B3 (niacin)
Pantothenic acid (B5)
Biotin (B7)
Vitamin B6
Vitamin B12 (cyanocobalamin)
Folate (folic acid and B9)
Vitamins are grouped into two categories:
Fat-soluble vitamins are stored in the body’s fatty tissue. The four fat-soluble vitamins are vitamins A, D, E, and K. These vitamins are absorbed more easily by the body in the presence of dietary fat.
There are nine water-soluble vitamins. They are not stored in the body. Any leftover water-soluble vitamins leave the body through the urine. Although, the body keeps a small reserve of these vitamins, they have to be taken on a regular basis to prevent shortage in the body. Vitamin B12 is the only water-soluble vitamin that can be stored in the liver for many years.
