Active Vitamin B6 Pyridoxal-5-Phosphate P5P Suppliers and Factory in China
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
01 Fast Onset, No Conversion Needed
Ordinary vitamin B6 (pyridoxine) needs to be converted to P5P by the liver before it can work, and conversion efficiency is affected by age, liver and kidney function, and genetic polymorphisms (such as ALPL gene mutations reducing conversion rate by 50%). P5P directly provides an active form, with bioavailability increased by more than 70% — especially suitable for people with metabolic disorders (e.g., the elderly and patients with liver disease).
02 Higher Safety at High Doses
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 carry this risk. Clinical studies have confirmed its safety at doses as high as 1000 mg/day (Eur J Clin Nutr, 2018).
03 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
-
1 Amino Acid and Homocysteine MetabolismAs 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.
-
2 Neurotransmitter Synthesis and Mood RegulationDirectly 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).
-
3 Hemoglobin and Immune SupportSynergizes with folic acid and vitamin B12 to promote hemoglobin synthesis and prevent iron deficiency anemia; activates T lymphocyte proliferation and antibody production to enhance anti-infection ability.
-
4 Glycogen Metabolism and Hormone BalanceRegulates glycogen decomposition and insulin sensitivity to assist blood sugar homeostasis; promotes estrogen metabolism to reduce the risk of breast hyperplasia and gynecological tumors.
-
5 Antioxidant and Skin HealthDelays skin aging by removing free radicals and inhibiting the production of advanced glycation end products (AGEs); regulates sebaceous gland function to improve acne and seborrheic dermatitis.

Frequently Asked Questions (FAQ)
Q What is the difference between P5P and regular vitamin B6 (pyridoxine)?
P5P (Pyridoxal-5-Phosphate) is the biologically active coenzyme form of vitamin B6, meaning the body can use it immediately without hepatic conversion. Regular pyridoxine must first be metabolized by the liver, a process that can be significantly reduced by age, liver conditions, or genetic variants such as ALPL gene mutations. P5P therefore offers superior bioavailability and faster action.
Q Is P5P safe to take at high doses over the long term?
Yes. Unlike conventional pyridoxine, which may cause peripheral neuropathy at doses exceeding 50 mg/day due to metabolite accumulation, P5P does not carry this risk. Clinical research published in the European Journal of Clinical Nutrition (2018) confirmed that P5P is safe at dosages up to 1000 mg/day.
Q How does P5P support heart health?
P5P acts as a coenzyme for cystathionine β-synthase, catalyzing the conversion of homocysteine — an amino acid associated with elevated cardiovascular risk — into cystathionine. Studies indicate that each 1 mg increase in P5P intake is associated with a 15% reduction in blood homocysteine (Hcy) levels, thereby helping to lower the risk of cardiovascular disease and cognitive decline.
Q Can P5P help with mood and mental well-being?
Yes. P5P is directly involved in the biosynthesis of key neurotransmitters including serotonin, dopamine, and GABA. Clinical trials have demonstrated that supplementing with 50 mg/day of P5P can reduce the emotional symptoms of premenstrual syndrome (PMS) by up to 40% (J Womens Health, 2016), and may also support general mood balance, reduce anxiety, and improve sleep quality.
Q Who is most likely to benefit from P5P supplementation?
P5P is particularly beneficial for individuals with metabolic sub-health conditions such as hyperhomocysteinemia or prediabetes, those experiencing high stress, sleep difficulties, or neurological concerns, women dealing with PMS or menopausal hormonal shifts, and athletes or individuals on high-protein diets who need enhanced amino acid metabolism and muscle recovery support.
Q Does P5P interact with other minerals or nutrients?
P5P is notably stable across a broad pH range, including in gastric acid, which ensures efficient intestinal absorption. Importantly, unlike some forms of vitamin B6, P5P does not exhibit antagonistic interactions when co-administered with essential minerals such as magnesium and zinc, making it well-suited for use in comprehensive multivitamin and mineral formulations.
