Hi, I am on 3 x 500g daily. The doctor started me on 2 a day to ease me in for a week. Initially I did have very smelly farts (frankly, was happy to pay my husband back for all those years!!!! and sometimes loose bowels but it settled quite quickly. Again, not sure how much it actually helps my blood sugars but I had a very high reading at first so doctor didn't really give me an option! No harm in giving it a try.
