I saw that he uses the Thorne curcumin called meriva. My ob/gyn suggested I try this for a shoulder issue I have. I tried some other brand along time ago but it gave me heartburn and was not excited to try Thorne's. But Thorne's did not cause any problems. So that's a good thing.

Thorne is very reputable and in the past was only available to practitioners. But now you can get it online from iherb.com. Thorne has a few different combinations of the B vitamins. There's one called methyl guard plus that has the folate and B12.
We use Thorne, Life Extension and Jarrow (and some others).
The one thing I caught, and I need to research further, is finding the adequate dose of folate. Sounds like it varies by individual. I need to check out this site on MTFHR and see if I can find something about it:
