the bottle says it helps with the motility of your stomach which is also good for IBS and any stomach related issues. It is all natural. I am beginning to wonder if that is why I can eat quite a few things...more than most people here...and don't have any vomiting or bowel issues. Sometimes I feel fuller faster than other times but I find it's because I've eaten something about 3pm before dinner. But 6 meals a day is not an option for me. So Equate is my go-to protein supplement. Get it at Walmart. Recommended by my dietician because it tastes better than Ensure, same as Ensure for ingredients and proteins/vitamins/minerals, and is cheaper.
