There are 13 essential vitamins that our body need. They are categorized into 

1. Water soluble

2. Fat soluble

Water-soluble vitamins dissolve in water, which means these vitamins and nutrients dissolve quickly in the body. Unlike fat-soluble vitamins, water-soluble vitamins are carried to the body’s tissues, but the body cannot store them.

Water-soluble vitamins are Vitamin B1, B2, B3, B5, B12, B6, B7 & B9 and Vitamin C.


Fat-soluble vitamins are soluble in fats. They are absorbed by fat globules that travel through the small intestines and into the general blood circulation within the body. Unlike water-soluble vitamins, fat-soluble vitamins are stored in the body when they are not in use.

Fat-soluble vitamins are - Vitamin A, D, E and K.
