How It Works

Pyridoxal-5-phosphate (P5P) is a cofactor for over 150 enzymes, primarily in amino acid metabolism. Essential for neurotransmitter synthesis (serotonin, dopamine, GABA, norepinephrine), haemoglobin formation, homocysteine to cysteine conversion, and immune cell production.

25-100 mg P5P daily (do not exceed 200 mg long-term)

With meals, morning or afternoon preferred

Recommended Form

Pyridoxal-5-Phosphate (P5P active form)

Side Effects

Peripheral neuropathy at chronic high doses (>200mg/day). Tingling, numbness. Photosensitivity. Use P5P form for safety.
