Purchased these supplements for our Westie who suffers from a grumbling tummy, which was getting progressively worse. After consulting with our vet and being advised that purchasing through them would be around £100 for each tub of Digestive enzymes supplements, we decides that we would look around on the internet which is where we found Supplements Wise Ltd. By now our westies condition had become worse and he was in a bad way with indigestion (called borborygmus). Borborygmus is the gurgling sound made by normal bowels. The sound occurs when gas moves through the gut and is pushed along by waves of muscle contraction in the intestinal wall. This was happening about 4 or 5 times a week, until we gave him the supplement which we started at the beginning of April, since then he has been bothered once, which is why I've held off writing a review to make sure that the supplement works. So if your pet suffers from this condition, i can recommend these supplements, our westie has a new lease of life since starting on them. Thank you Supplements Wise Ltd.
