When I first took creatine from an Amazon dealer I had gut problems. I later bought a "micronized" creatine (similar to https://bulevip.com/es/3418-optimum-nutrition-creatina-powder-300-gr-5060245605397.html?utm_medium=cpc&utm_source=google&utm_campaign=pmax-top&gad_source=1&gad_campaignid=21460194675&gbraid=0AAAAA97b22I12_SZTsXA6AfcodFuqB3Va&gclid=Cj0KCQjw2IDFBhDCARIsABDKOJ6Uhxk3lxgVFig2JPoM6UQyD82ZlW8m4Re7W1F6Vezsp9WsyO3Gi4AaAtcqEALw_wcB https://bulevip.com/es/3418-optimum-nutrition-creatina-powde...) and did not experience any gut problems. Taking the same product now for 3 years. Inbetween I used some other variant from time to time and have the theory that some vendors sell a not clean product that interferes with your gut.
