Pyridoxal-5-Phosphate (P5P) Active Vitamin B6 - High-Quality Factory Suppliers in China
C8H10NPO6·H2O
Pyridoxal-5-phosphate (P5P) is the active coenzyme form of vitamin B6 (pyridoxine) in the body (no need for liver conversion), directly involved in more than 100 enzymatic reactions, showing significant advantages in metabolic regulation, neuroprotection and anti-oxidation, and becoming the preferred ingredient for modern nutritional supplements.

No Need for Metabolic Conversion — Fast Onset
Ordinary vitamin B6 (pyridoxine) needs to be converted to P5P by the liver before it can work, and the conversion efficiency is affected by age, liver and kidney function and genetic polymorphism (such as ALPL gene mutations — the conversion rate decreases by 50%). P5P directly provides an active form, and its bioavailability is increased by more than 70%, which is especially suitable for people with metabolic disorders (such as the elderly and patients with liver disease).

Higher Doses Are Safer
Long-term high-dose supplementation of ordinary B6 (>50 mg/day) may cause peripheral neuropathy (due to accumulation of pyridoxine metabolites), while P5P does not have this risk. Clinical studies have confirmed that its safety is as high as 1000 mg/day (Eur J Clin Nutr, 2018).
-
Broad Spectrum pH Stability
P5P remains stable in gastric acid (ordinary B6 is easily degraded in an acidic environment), ensuring efficient intestinal absorption, and has no antagonistic effect when combined with minerals (such as magnesium and zinc).
As a coenzyme of transaminase and cystathionine β-synthase, P5P catalyzes the conversion of homocysteine to cystathionine, reduces the homocysteine level in the blood (for every 1 mg increase in P5P, Hcy decreases by 15%), and reduces the risk of cardiovascular disease and cognitive decline.
Directly participates in the synthesis of serotonin, dopamine, and GABA, improving anxiety, depression, and sleep quality. Clinical trials have shown that P5P (50 mg/day) can reduce the emotional symptoms of premenstrual syndrome (PMS) by 40% (J Womens Health, 2016).
