What are Vitamins? Explain their functions and types.


Vitamins are a group of essential nutrients that enable our body to function properly and to stay healthy, by fighting off with diseases.

Our body cannot produce vitamins itself, so we must get them through the food we eat or in some cases through the supplements.

 

The nutrients that we get from vitamins help our body to carry out essential functions such as:

1.Production of skin, muscle, and bone

2.Converting food into energy

3.Maintenance and repairing of cells, tissues, and organs

4.Strengthening the immune system

Vitamins are divided into two parts :

1. Fat-Soluble: These vitamins are stored in our fat cells, so it requires fat in order to be absorbed.

2. Water-Soluble: These vitamins are not stored in our body, which means the body needs a continuous supply of them, therefore they need to be replenished daily.
