Pyridoxal 5-Phosphate

by Klaire Laboratories


This water-soluble vitamin is involved in a number of metabolic reactions throughout the human body and functions as a coenzyme. The metabolism of sulfur-containing amino acids, such as the conversion of methionine to cysteine is also dependent upon the vitamin. P-5-P is also involved in the conversion of tryptophan to 5-hydroxytryptamine (5-HT).


Product details: Vitamin B6 may be administered in the form of pyridoxine hydrochloride, pyridoxal, or pyridoxamine. All forms are converted by the liver to pyridoxal-5-phosphate, or P-5-P, and is the form of vitamin B6 utilized by the body. This water-soluble vitamin is involved in a number of metabolic reactions throughout the human body and functions as a coenzyme.

P-5-P is also involved in the conversion of tryptophan to 5-hydroxytryptamine (5-HT).

The requirement for vitamin B6 in adult human nutrition has been set at 2 milligrams per day, however; studies with slightly higher amounts indicate a decrease in hypertension in humans and possible protective effects from myocardial ischemia. A deficiency of B6, while rare in Western countries, exhibits as facial skin lesions. Prolonged deficiencies can result in convulsive seizures as well as pain and swelling in carpal joints, similar to what is observed in carpal tunnel syndrome. Certain members of the population, such as women, dieters, adolescent girls, alcoholics, and the aged were consistently shown to take in less than the RDA of vitamin B6.

While found in meats, liver, whole grains, and vegetables, substantial amounts of B6 are lost in cooking and oxidation. For this reason, B6 is best taken as a supplement to insure adequate tissue concentrations of this vitamin.

Those persons taking levodopa or isoniazid should consult their physician before taking large doses (over 200 mg) of any form of vitamin B6.
