"The issue you bring up about the sulfur amino acids (methionine, homocysteine, cysteine, glutathione, taurine, sulfate, etc) is maddeningly complex. So many of us have problems in this area.
People who have methylation problems will be affected in one way (I think too much homocysteine)."
But Joe, these are precisely the things that Andy Cutler addresses so vaguely, and I would suggest he does so because he's not up to speed on methylation issues at all.
Instead, his dated (and possibly dangerous) advice is to take b50 complex 3-4 times a day. B-complex vitamins are often impossible for many to tolerate, and also full of SYNTHETIC "folic acid", the type of folate that the body was never meant to metabolize. It can build up in folks with methylation problems, and block the body's ability to use active folates.
He's always dismissive of methylation problems, instead telling folks to chelate (for what, years and years?) while they may become dangerously deficient in b12 and folate in the process.
It's very telling that many on the overloaded FDC yahoo group have been chelating for 5-10 years without much progress, yet Andy did it in a year?
