I think if you take enough of it you can get some gastric distress but of course you take enough of any powdered substance uh mix in water you're going to get a a gastric distress response and I what I've noticed about gastric distress with things like uh creatine glutamine and even protein powders for that matter is that if you build up to it over the course of a few days then can get away with using much higher dosages without any issue
