Vitamins

Vitamins are organic molecules that are essential for the proper functioning of the human body. They cannot be synthesized by the body and must be obtained from the diet. There are 13 essential vitamins, each of which plays a specific role in maintaining health.

What are the different types of vitamins?

There are two main types of vitamins: water-soluble vitamins and fat-soluble vitamins.

Water-soluble vitamins dissolve in water and are easily absorbed by the body. They are not stored in the body, so they must be consumed regularly. The water-soluble vitamins include vitamin C, vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B7 (biotin), vitamin B9 (folic acid), and vitamin B12 (cobalamin).

Fat-soluble vitamins dissolve in fat and are absorbed by the body along with fat. They are stored in the liver and fatty tissues, so they do not need to be consumed as often as water-soluble vitamins. The fat-soluble vitamins include vitamin A, vitamin D, vitamin E, and vitamin K.
