I’ve been struggling with IBS, slow digestion and GERD for several years now. Recently, my gastro doctor had me try L-Glutamine. First, I started the dose at 500mg 3 times a day on an empty stomach. I’ve increased the dose up to 3grams a day, dosing 1000mg 3 times a day on an empty stomach. The goal that my Dr and I set was to reach 12grams a day. At the 3 gram dose, I’ve had some considerable improvement in symptoms with bloating and acid reflux, but I noticed I getting some serious joint pain in my hands, feet and knees. I think I need to stop because the pain is getting worse. Can someone tell me why my joints are aching in response to the L-Glutamine treatment?
