ISS Whey Matrix 5lbstar rating 3John CardinaliOctober 8, 2010Everything I wanted in a powder except---Acesulfame Potassium!!! WTF! Why make a product with a natural safe sweetener like Stevia--which is a key ingredient 4 me--and ruin it by putting in a GREATER amount of Acesulfame Potassium which has been linked to Cancer--and ruin the entire powder. I don't want to just single out ISS because they do a good job with 95% of this product--most manufacturers still don't get it--Artificial sweeteners Sucralose, Aspartame,Acesulfame Potassium, saccharin, etc--actually deceive the body w/artificial sweetness which just makes us crave more sweets--studies have shown they make u fatter! Cancer is also tied to sucralose and aspartame should never have gotten on the market unless you want dementia and parkinson's. GET A CLUE MANUFACTURERS!NO ARTIFICIAL SWEETENERS ARE GOOD FOR ANYONE--this goes for COMBAT to.
