I am bed-ridden with severe me/cfs. Have been doing rich van K's meth protocol abt 9 mths. Now newly diagnosed with homozygous C677t. I have read that (with this gene mutation) i should avoid folic acid because it blocks uptake of methylfolate. But the neurological health formula i take as part of protocol contains folic acid. 1) Should i stop taking it? 2) How important is it to stop ingesting folic acid? 3) It seems x difficult to find a multivit without folic acid!
