Hi Dave,
In what respect are you thinking of it? I haven't personally ever needed to try it but it seems to have been around for some time as a natural remedy for abdominal bloating, acid indigestion and constipation.
I have big reservations about the manufacturers recent claims that it also benefits diabetics because the vitamin B it contains turns sugars and starches into water and carbonic acid gas (which can leave the body via the lungs, bowel and kidneys). An interesting claim since there is absolutely no record of vitamin B having this ability! Incidentally vitamin B is one of many vitamins that have been added to the basic whey product, so you could get the same results by simply taking a vitamin supplement!
