How it works

Essential for protein metabolism, immune function, and neurotransmitter synthesis. Strong evidence supports its role in reducing PMS symptoms and morning sickness, with emerging evidence for anxiety reduction at high doses.

Acts as a coenzyme for over 100 enzymes, primarily in protein metabolism and the synthesis of neurotransmitters like GABA, serotonin, and dopamine.

Safety

  • Chronic intake above 100mg/day is associated with sensory neuropathy.
  • Symptoms of toxicity include tingling, numbness, and loss of balance.
  • Risk is higher with the pyridoxine HCl form than the active P5P form.
