Optifast uses dry milk concentrate for the Protein not an isolate, Concentrates have much higher levels of lactose. Protein Isolates have little to none. It's possible you are having lactose issues with the high concentration. Try a different brand of protein / Meal Replacement that doesn't contain a protein concentrate, but rather has protein isolates as the protein source and see if that helps you any. Or you can keep taking the Optifast and try to see if taking some Lactaid helps relieve the symptoms. Share this post Link to post Share on other sites

Matt Z 4,139 Posted October 2, 2018 BariatricFusion is what we were told to use pre-op at my center. I also use Gold Standard Proteins, and Isopure proteins. The big thing to look for is the word "Isolate". ESP if you have lactose tolerance issues. Share this post Link to post Share on other sites
