Vitamin B6 health

Vitamin B6 is a family of chemically-related compounds including pyridoxamine and pyridoxal which are found in animal products, and pyridoxine which is found in plants. The form most commonly used in fortified foods and supplements is pyridoxine.



Like the other B complex vitamins, vitamin B6 is involved in the functioning of enzymes involved in the release of energy from food. The coenzyme forms of vitamin B6 are pyridoxal 5' phosphate and pyridoxamine 5' phosphate, and these are necessary for nearly 100 enzymatic reactions. These include the synthesis and breakdown of amino acids, the conversion of amino acids to carbohydrate or fat, and the conversion of one type of fat to another. Thus, it is involved in the manufacture of most protein-related compounds and plays a role in almost all bodily processes.

Cardiovascular system

Vitamin B6 is essential for the manufacture of fat-derived substances known as prostaglandins which are involved in processes such as blood pressure regulation and heart function. Vitamin B6 is also necessary for red blood cell formation.

Vitamin B6 healthImmune system

Vitamin B6 plays a vital role in maintaining a healthy immune system by affecting functions such as cell multiplication and antibody production.

Nervous system and brain

Adequate vitamin B6 is vital to the healthy development and function of the nervous system. It is involved in the manufacture of several neurotransmitters including serotonin, GABA, dopamine and noradrenaline, and plays an important role in regulating mental processes and mood. Concentrations of vitamin B6 are up to 25 to 50 times higher in the brain than in the blood.

Skin and hair

Vitamin B6 is important in maintaining healthy hair and skin.


Vitamin B6 plays a role in modulating the effects of hormones, including male and female sex hormones and adrenal hormones.

Other functions

Vitamin B6 is also involved in the manufacture of the genetic material of the cell, sodium-potassium balance, histamine metabolism, the conversion of tryptophan to niacin, absorption of vitamin B12 and the production of hydrochloric acid.
