I don't think that I've posted this before. It's from KClM - a company that's producing soy kefir products. Two small trials indicated benefits - if you took enough of their grains - in ME/CFS/FM patients. I must say though that their explanation of the benefits seem kind of strange to me; it focused on the efficacy of soy rather than the effects of the bacteria? They are available for questions; if anyone has any questions that they would like asked let me know - I'm going to send some in.
