Vitamin B6 (Pyridoxine)

Vitamin B6 (Pyridoxine) Description and Overview:

Vitamin B6, also known as pyridoxine, is a water-soluble B vitamin. Vitamin B6 actually describes several different compounds, including pyridoxine, pyridoxal, and pyridoxamine.

Vitamin B6 (pyridoxine) acts as a coenzyme and plays a role in the metabolization of protein and carbohydrates into energy. It is also required for the production of insulin, as well as both red and white blood cells. Pyridoxine is particularly vital for keeping nerve and muscle cells healthy. Vitamin B6 is needed for the creation of DNA and RNAl. Risk of vitamin B6 deficiency is quite rare, because the vitamin is contained in the majority of foods. A deficiency most often results from poor absorption of nutrients via the intestines (as in the case of chronic alcoholism or chronic diarrhea). Read more about the benefits and functions of vitamin B6 and signs of vitamin B6 deficiency.

Good food sources of vitamin B6 are whole grains, liver, fortified cereals, spinach, bananas, beans, nuts, and legumes. Vitamin B6 can actually be found in varying amounts in nearly every food. Pyridoxine requirements is proportional to the amount of protein one consumes. Read more about sources of vitamin B6 and the daily requirement of vitamin B6.

Vitamin B6 toxicity is rare, and the vitamin is safe at intakes of about 200 milligrams per day for adults. Toxicity can result in neurological problems, including numbness in the legs and loss of balnce, when ingested in high doses (over 200 milligrams a day) for extendied periods.

Vitamin B6 (pyridoxine) is the label that actually describes 6 specific compounds, including pyridoxine, pyridoxal, pyridoxamine, as well as their respective phosphate derivatives, pyridoxine 5-phosphate, pyridoxal 5-phosphate, and pridoxamine 5-phospate. The phosphate compounds play the most active role in many processes which involve the metabolization of amino acids and proteins. Pyridoxal 5-phosphate is the form most critical to metabolic processes.

Vitamin B6 is located mainly in the liver and in the muscles. The liver uses it to produce pyridoxal phosphate. pyridoxal phosphate acts as coenzymes which are integral to metabolizing both amino acids and glycogen. Pyridoxal phosphate also acts as a coenzyme in the production of niacin (vitamin B3) and the production of various neurotransmitters, including serotonin, norepinephrine, dopamine, and gamma-aminobutyric acid (GABA)..

Pryridoxal 5-phosphate and pyridoxamine 5-phosphate are the primary types of vitamin B6 which originate from animal sources. Pyridoxine, pyridoxine 5-phosphate generally originate from plant sources.
