My gut is pretty messed up so I can't tell you of the amazing difference this might have. What I do know is that I am on a high dose antibiotic for 3 months and I haven't had any of the typical negative side effects that are expected with it. I plan to continue to take this during the rest of my antibiotic use and after to heal my gut. This tastes great in coffee and I love it in ice water. This is the only product available with this much L-Glutamine. I know these supplements are what is recommended to heal the gut and I'm glad I can get them all in 1 tasty powder!
Length of Use: 3–6 months
Bottom Line: Yes, I would recommend this to a friend
