Ive been having some trouble with dosages for kpu. I have been tolerating 240mg of zinc ok. 10mg biotin is fine. I cant tolerate regular b6 so I must take p5p. Klinghart recommends 50mg a day and to take it only at night. This seems rather low and i dont understand why take it at night when I get energy from it. How high can you go with p5p? I also hear it can cause neuropathy but it only helps mine. He also says 60mg to 240mg of lithium orotate a day! Is that a typo?! He also says niacinamide 1000mg 3x a day. Wont this contradict any methylation protocol? Methylation seems to have helped me a ton so far.
