Vitamin B Complex

Vitamin B complex or B-group are water soluble vitamins that aid in the metabolism of the body system. They help in the multiplication of cells for the formation of new DNA.The vitamin B complex consists of the following; vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (panthotenic acid), vitamin B6 (pyridoxine), vitamin B7 (biotin), folic acid and vitamin B12 (cyanocobalamin).

Vitamin B1 (first to be discovered) strengthens the immune system and enhances the ability of the body to undergo stressful conditions. Thiamine is needed by the body to form adenosine triphosphate (ATP) which provides energy to the body. It also tends to co-ordinate the activities of the nerves and the muscles and aids normal functioning of the heart activity.

Vitamin B2 is needed to protect the cells fro

m oxygen damage because of its roles in the metabolism of fats, carbohydrates and proteins. Riboflavin helps to keep the mucous membranes in a healthy conditions. Vitamin B2 is responsible for that yellowish colouration of the urine when vitamin tablets are administered.

Vitamin B3 is responsible for the conversion of proteins, fats and carbohydrates into energy that will be used by the body. Niacin aids in DNA repair, and the formation of the steroid hormones found in the adrenal gland.

Vitamin B6 enhances the metabolic rate of carbohydrates, fats and amino acids. Also known as Pyridoxine, Vitamin B6 aids the normal functioning of nerves and the formation of red blood cells in the body.

Folic acid is needed for the formation of red blood cells, synthesizing of DNA and normal development of the nervous system.

Vitamin B12 is responsible for the formation and maturation of red blood cells, normal nerve functioning and the synthesizing of DNA.
