Vitamins are essential substances required by the body to maintain the basic functions and health.

Vitamins can be classified into two types: fat-soluble ( A, D, E, and K) and water-soluble ( C vitamin and B vitamins). Unlike fat-soluble vitamins, the water-soluble vitamins need constant replacement because they are not stored inside the fatty tissue or liver as fat-soluble do, but instead are carried to the body’s tissues.

Vitamin Categories

Vitamins could be identified into two main categories, which are Water-soluble and Fat-soluble. Each of them has its own unique ways of storing and excreting in our body. Unlike fat-soluble, human needs to take water-soluble daily as supplements because of the fast absorption.
