I hear ya regarding supplements. Everybody has different recommendations, so it's almost impossible to feel good about actually taking a supplement, and then on top of it finding the best form of it.

Before embarking on the PS starch, I had stopped all supplements (curcumin with piperine was the last to go as I had seen a couple theories that it could harm my helminths).

Thanks for the link to Dave's supplement guide! I eat quite a bit of meat (lamb in particular), so I'm not deficient in the traditional sense for B12. But the daily intake recommendations for B12 vs folate are quite a bit different

B12: http://ods.od.nih.gov/factsheets/VitaminB12-HealthProfessional/#h2
Folate: http://ods.od.nih.gov/factsheets/Folate-HealthProfessional/#h2

I personally got this guy http://www.pureencapsulations.com/folate-400.html mostly based off of Chris Kresser's recommendation http://chriskresser.com/folate-vs-folic-acid. If you were interested in taking the 2 in conjunction, they do have this http://www.pureencapsulations.com/b12-folate.html. I'm also following his general dosing advice. I figure I'll take either 1 or 2 400 mcg capsules a day.

Because it was a mouse study, I certainly wouldn't put a lot of weight in it, and don't know if there's any dosing information that you could take from it.

There was another mouse study that had similar results http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0032094#pone-0032094-g005

I don't have any expectations for the B9, but it seemed like a relatively harmless supplement to throw into the mix.

Also Chris Kresser just did a podcast with the guy who started Taymount clinic, not a lot of new info, and not that much specific to AI disease, but worth a listen. I'd like to think he hints that he's toying with the idea of making pills.
