Vitamins are organic molecules that require a small amount for the proper functioning of our body’s metabolism. They are necessary for growth, vitality, health, general well being, and for the prevention and cure of many health problems and diseases. the vitamin cannot produce energy for our bodies. The all-natural vitamin is organic food substances found only in living things, that is, plants and animals. With few exceptions, the body cannot manufacture or synthesize the vitamin. we can usually get all our vitamins from our food and also by supplements, our body can also synthesize vitamin D and vitamin K. Our body can’t synthesize any other vitamin. Every vitamin has a specific function in our body, so the deficiency of a certain vitamin can cause a certain health problem. Vitamins are classified by their biological and chemical activity, not their structure. There are many vitamins our body needs, they are following-
Classification of best natural Vitamins
Vitamin and Their Chemical Name
1. Retinol (Vitamin A)
2. Vitamin B Complex
- Thiamine (Vitamin B1)
- Riboflavin (Vitamin B2)
- Niacin and Nicotinic acid (Vitamin B3)
- Pantothenic acid (Vitamin B5)
- Pyridoxine (Vitamin B6)

3. Ascorbic acid (Vitamin C)
4. Vitamin D
- Ergocalciferol (Vitamin D2)
- Cholecalciferol (Vitamin D3)
5. Tocopherol (Vitamin E)
6. Phylloquinone or Menaquinone (Vitamin K)
Type of Vitamins
Vitamin is divided into two parts according to their solubility that is-
These vitamins can dissolve with water, the water-soluble vitamin is carried to the body tissues but we can not store them in our body. Many types of water-soluble vitamins are synthesized by bacteria. The water-soluble vitamin is vitamin B complex and vitamin C.
Fat-soluble vitamin is absorbed through the intestinal tract with the help of lipids (fats). This vitamin can dissolve with fat, fat-soluble vitamin is stored in the body for a long period. Fat-soluble vitamin is vitamin A, D, E, K.
Vitamin is also divided into two groups according to Heat response-
1. Heat stable –
These are can’t destroy by cooking, because they are heat resistant so this vitamin called Heat stable vitamin. Heat stable vitamin is Vitamin A, D, E, K, and some B vitamins.
2. Heat unstable –
These vitamins can destroy by cooking. Heat unstable vitamin is Vit A, C, and some B group vitamin.
Anti Oxidant Vitamin – These vitamins destroy the free radicals found in our bodies.
