Vitamin B6 Pyridoxine

Vitamin B6 (Pyridoxine)

comprises 3 forms (vitamers): pyridoxine, pyridoxal and pyridoxamine, and has a central role in the metabolism of amino acids. It is involved in breaking down glycogen and has a role in the modification of steroid hormone action. It is also essential for the formation of red blood cells and the metabolism and transport of iron. Together with folate and vitamin B12, vitamin B6 is required for maintenance of normal blood homocysteine levels. Raised homocysteine is a risk factor for cardiovascular disease.

Deficiency :

Deficiency of vitamin B6 is rare because it is widely distributed in foods and is synthesised by the body’s gut flora. Deficiency may only occur as a complication of disease or prolonged administration of certain drugs.
