I have been taking p5p for about 1 1/2 years now for pyroluria issues. My liver is weak so I have been taking this product instead of regular b6. Dream recall returned for a few days when I first started taking this product and then each time I have increased the dose. I am currently taking 150 mg of p5p a day. My concern is that over the time I have been taking p5p my phosphorus level has been gradually increasing as measured by hair analysis. It is now in the abnormally high range (300 ug/g with a reference range of 120-190. About three months after I first began taking it, it was at 200. I am wondering if it is the phosphate component of the p5p which might be leading to the high phosphorus level. Keeping in mind my weak liver, would it be better to take regular b6 instead? Would my body then have the excess phosphorus to do the converting on its own? Or is the high phosphorus level a non-issue?
