Active Vitamin B6 Pyridoxal-5-Phosphate P5P Suppliers and Factory in China - High Quality Derivatives
C8H10NPO6·H2O
Description
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.
Core Advantages Compared to Ordinary Vitamin B6
-
⚡
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).
-
🛡️
High 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).
Core Nutritional Health Effects
01
Amino Acid & Homocysteine Metabolism
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.
02
Neurotransmitter Synthesis & Mood Regulation
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).
03
Hemoglobin & Immune Support
Synergize folic acid and vitamin B12 to promote hemoglobin synthesis and prevent iron deficiency anemia; activate T lymphocyte proliferation and antibody production to enhance anti-infection ability.
04
Glycogen Metabolism & Hormone Balance
Regulate glycogen decomposition and insulin sensitivity to assist blood sugar homeostasis; promote estrogen metabolism to reduce the risk of breast hyperplasia and gynecological tumors.
05
Antioxidant & Skin Health
Delay skin aging by removing free radicals and inhibiting the production of advanced glycation end products (AGEs); regulate sebaceous gland function to improve acne and seborrheic dermatitis.

Frequently Asked Questions (FAQ)
QWhat is Pyridoxal-5-Phosphate (P5P) and how does it differ from regular vitamin B6?
P5P is the bioactive, coenzyme form of vitamin B6. Unlike regular vitamin B6 (pyridoxine), which must be converted by the liver into P5P before it can be used, P5P is immediately available to the body. This means faster onset, higher bioavailability (over 70% greater), and better suitability for individuals with impaired liver function or genetic conversion limitations.
QIs P5P safe to take in high doses?
Yes. Clinical research has confirmed that P5P is safe at doses up to 1000 mg/day (Eur J Clin Nutr, 2018). Unlike standard pyridoxine, long-term high-dose use of P5P does not carry the risk of peripheral neuropathy, making it a safer choice for individuals who require higher supplementation levels.
QHow does P5P support cardiovascular health?
P5P acts as a coenzyme for enzymes involved in homocysteine metabolism. Elevated homocysteine is a known risk factor for cardiovascular disease and cognitive decline. Research shows that for every 1 mg increase in P5P intake, blood homocysteine (Hcy) levels decrease by approximately 15%, helping to lower cardiovascular risk.
QCan P5P help with mood and mental health?
Yes. P5P is directly involved in the synthesis of key neurotransmitters including serotonin, dopamine, and GABA. Clinical trials have demonstrated that supplementing P5P at 50 mg/day can reduce emotional symptoms associated with premenstrual syndrome (PMS) by up to 40% (J Womens Health, 2016), and may also help manage anxiety, depression, and poor sleep quality.
QWho can benefit most from P5P supplementation?
P5P is especially beneficial for individuals with metabolic sub-health conditions (e.g., hyperhomocysteinemia, prediabetes), those experiencing high stress or sleep issues, women dealing with PMS or menopausal hormone fluctuations, athletes and high-protein dieters seeking faster amino acid metabolism, and elderly or liver-compromised individuals who may have reduced conversion efficiency from standard B6.
QDoes P5P interact with other supplements or minerals?
P5P is highly compatible with other nutrients. Unlike some forms of vitamin B6, P5P has no antagonistic effects when combined with minerals such as magnesium and zinc. It also works synergistically with folic acid and vitamin B12 to support hemoglobin synthesis and overall metabolic health. Its broad pH stability ensures it remains effective even in the acidic environment of the stomach.
