Folic Acid Thanks, Freddd. I think you are probably right about the Thorne. They told me their product is from merk but would not reveal if it is the patented metafolin. I have not had the obvious die off, detox effect from it like I did with the metagenics products. If the Deplin site is right, there the MTHFr conversion or lack there of takes place between 5 methyl THF and the production of l- methyl. Metafolin is supposed to be l-methyl as is the deplin product, which I am assuming is and all are metafolin. OK. So that would probably mean that MTHFr is at least slow even though I have heterogenous mutations (I think every MTHFr gene yasko tests, I am hetero on). What do you think about a potential need for folicin? I know yasko includes some in as does Rich. B Right has folic acid.. I know Rich does not use folic acid and yasko limits i feel pretty certain because the folates compete with each other and that potentially FA will block the active forms from cells. What do you think of this idea? You are dosing metafolin much higher, so thats different as well. What do you think of the lower doses of about 300mcg 5-methyl THF (0r really l- methyl) and 100 folicin?
