Hi, I have had chronic zinc deficiency for a long time (I could tell because I've always had skin problems and white spots on my nails). I also had severe malabsorption problems and have been helped by taking enzymes with every meal for about 6 months along with probiotics. I think my absorption problems are a lot better now thanks to enzymes, probiotics, lots and lots of fiber. A recent amino acid analysis showed that I was also severely deficient in B6. I then began to suspect pyroluria was the root cause of my problems. But I just got back my results and the result is 15 which is supposedly within the normal range. My question is could the reading be much lower now than just a couple months ago because of the large amounts of antioxidants Ive been taking (I am currently taking 300mg ALA 3x per day, 1g vitamin C 3x per day, 400IU of natural High Gamma vitamin E, selenium 200mcg, amongst other herbal/mineral supplements) and also the Zinc (65mg along with a pretty high protein diet) and 50mg of P5P? My doctor wants me to get off all my supps for about a week and retest but I am hesitant because I have made so much progress. Anybody with experience can offer any advice on whether a reading of 15 could still be pyroluric and that its just controlled now by all the supps I take?
