Pyridoxal-5-Phosphate (P5P) is the active coenzyme form of vitamin B6 that directly supports over 100 enzymatic reactions in the body. P5P serves as a cofactor for amino acid decarboxylases and transaminases, making it essential for neurotransmitter synthesis and protein metabolism.
Reported Benefits (Provisional)
Origin & History
Pyridoxal-5-phosphate (P5P) is the active form of vitamin B6, naturally found in foods like fish, poultry, and grains. It is produced synthetically for supplements to enhance bioavailability and effectiveness.
Research Narrative (Provisional)
Clinical trials and observational studies confirm P5P's role in supporting neurological and cardiovascular health. Its superior absorption compared to other B6 forms is well-documented.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
- Provides active vitamin B6. - Bioavailable form, easily utilized by the body. - Free from artificial colors and preservatives.
Reported Mechanism (Provisional)
P5P functions as the primary coenzyme for pyridoxal kinase and amino acid decarboxylase enzymes, facilitating the conversion of L-DOPA to dopamine and 5-HTP to serotonin. It serves as a cofactor for transaminases including alanine aminotransferase (ALT) and aspartate aminotransferase (AST), enabling amino acid interconversion. P5P also activates glycogen phosphorylase for glucose metabolism and supports sphingolipid synthesis in neural tissue.
Clinical Narrative (Provisional)
Human studies show P5P supplementation at 50-100mg daily improves homocysteine metabolism and reduces plasma levels by 15-25% in controlled trials with 60-200 participants. Clinical research demonstrates P5P's superior bioavailability compared to pyridoxine HCl, with 2-3 times higher plasma concentrations achieved. Limited studies suggest benefits for carpal tunnel syndrome and PMS symptoms, though larger randomized controlled trials are needed. Evidence for cognitive and mood benefits remains preliminary, based primarily on mechanistic studies rather than robust clinical trials.
