Got my results back from the metabolic analysis urine test. How do these results look to you? I would be grateful if Rich could take a look. FIGlu 1.4 (range <1.5) Methylmalonic acid 0.9 (<1.9) FIGlu is borderline and MMA is within the normal range. Does this mean there is no methylation block? I know from previous blood tests that glutathione is very low. I have been following Rich's simpified protocol for a couple of weeks now (with the supplements he recommends) and have had no start up symptoms. I did feel a little better (from usual malaise) when I switched to taking my morning doses to bed time. I was expecting some reaction to the supplements, but not noticed much difference. I do have significant mercury levels and I believe mercury toxicity can affect this protocol; I suspended metal chelation with DMSA/ALA (Cutler method) before starting this, and I quite miss it as I usually feel better on chelation. Is it OK to continue with chelation whilst doing the methylation protocol? I would be grateful for any comments. Many thanks.
