Those with compromised liver function may have a problem converting B6 to this active form.

Description: Features Pyridoxal- 5- Phosphate (P- 5- P), the coenzyme form of Vitamin B6. P- 5- P does not have to be converted in the body and can go directly into metabolic cycles; P- 5- P may be more helpful as a Vitamin B6 Supplement than other forms. Vitamin B6 provides nutritive support for red blood cell synthesis and nerve tissue function as well as healthy protein metabolism and hormone synthesis. Size: 50ct Directions: As a dietary supplement, take 1 tablet up to two times daily. Serving Size: 1  Tablet    50 Servings per container

Pyridoxal-5'- Phosphate is an active co-enzyme form of vitamin B-6 required in amino acid metabolism, sphingolipid biosynthesis and degradation, hemebiosynthesis, neurotransmitter biosynthesis, collagen formation and glucocorticoid action. Sub-normal activity of the enzyme pyridoxal kinase, low levels of zinc or magnesium or impaired membrane transport can cause a deficiency of Pyridoxal-5-Phospate. For vitamin B-6 dysfunctions, intestinal malabsorption and amino acid deficiency conditions or increased need for B-6 due to toxicities, infections or metabolic impairments. A complete B-Complex supplement should also be taken.

This formula is a combination of pyridoxine hydrochloride and pyridoxal-5-phosphate (P-5-P, the coenzyme or "activated" form of B6). As P5P, vitamin B6 is extensively involved in the metabolism of amino acids, lipids and nucleic acids. Supplementation with vitamin B6 as P5P can be helpful for those unable to produce it efficiently from pyridoxine in the liver.* Excessive protein intake, alcohol or contraceptive use also indicates a greater need for vitamin B6. Vitamin B6 plays a crucial role in the multiplication of cells.
