I've used Twin Labs nutritional yeast, but I take very small amounts, so that a 16 ounce jar lasts more than a year. As to BMs, for me, it seems to be totally related to the amount of fiber in the diet, so now I eat some bran flakes with each meal. When I was producing no or almost no stomach acid, there were pieces of undigested food in the fecal matter, so I don't think that can really be compared to anything, because it was an extreme situation that most people never encounter. |
