Re: O/T: Methylation expert needed?

I don't know. From what I read it's more to do with your genetic build. I can't find any information on it. Besides, so many sites use "folate" and "folic acid" as if they were the same thing. Sometimes it's hard to find out of which form they are talking.

I did find this:
http://www.doctorsresearch.com/folic-acid.html
An Irish study found that the body has trouble converting more than 266 mcg of folic acid per day [2]. “(C)onsumption of more than 266 mcg of synthetic folic acid (PGA) results in absorption of unreduced PGA, which may interfere with folate metabolism for a period of years” [2]. A 2004 paper from the British Medical Journal confirmed what many natural health professional have known all along: since folic acid is unnatural and the body cannot fully convert large amounts of it into usable folate, this artificial substance can be absorbed and may have unknown negative consequences in the human body [4]. One of the biggest scientific concerns about folic acid is that even in amounts close to official daily recommendations, some of it is absorbed in unreduced form into the bloodstream with potentially dangerous results
