Is Thorne 5-MTHF an "approved" brand for L-5_Methyltetrahydrofolate? I was going to supplement with Metagenics Folapro via the crush/water method, but I see that Thorne's folate is a capsule, so I would be able to omit the crush portion of the method. But I wasn't sure if Thorne is Metafolin and if so, if it is 100% Metafolin. I'm new to this and am trying to read up on everything as fast as possible, but from what I've retained so far, I believe Merck's Metafolin is the preferred source of folate and that some supplements may contain only partial Metafolin. Any clarification would be greatly appreciated!
