I always give my patients B vitamins to help them with the “it is” conditions and to help fight gut-inflammation generally. The B vitamins also helps counteract an extremely inflammatory substance called homocysteine that can build up in the body. Particularly important are B6, B9 and B12. Whole grains are excellent sources of the B vitamins, except B12, which is found in meat and eggs, so vegans need to supplement with this. You need 1.5 mcg a day.
