Different Types of Vitamins and their Functions

Published on Monday, February 22, 2016
Dear Readers,
Vitamins are nutrients for human body needs to function and fight off disease. Human body cannot produce vitamins itself, so we must get them through food you eat or in some cases supplements.

Vitamin was invented by Sir Frederick Gowland Hopkins. The term vitamin was coined by Casimir Funk.

There are 13 vitamins that are essential to our body working well. Knowledge of the different types and understanding the purpose of these vitamins are important for good health.

Types and Examples of Foods

On the basis of solubility, there are two types of vitamins: fat-soluble vitamins and water-soluble vitamins.

A. Fat-soluble Vitamins are stored in your fat cells, consequently requiring fat in order to be absorbed.

The fat soluble vitamins: Vitamin A, Vitamin D, Vitamin E & Vitamin K

B. Water-soluble Vitamins are not stored in your body; therefore, they need to be replenished daily. Your body takes what it needs from the food you eat and then excretes what is not needed as waste. Here is a list of vitamin types and some common food sources:

The water soluble vitamins: Vitamin B1, Vitamin B2, Vitamin B3, Vitamin B5, Vitamin B6, Vitamin B7, Vitamin B9, Vitamin B12 and Vitamin C.
