I just read that more than 100 mg of Pyridoxine (B6) per day could be dangerous. I also remember reading about some users facing issues with 40 mg per day - that seemed to have causing toxicity symptoms. Personally, B6 suits me better than P5P. In your experience, how much do you consider a safe dosage? Is the serum Vitamin B6 (Pyridoxine) worth getting done?
