Hey guys, since being diagnosed with celiac disease, I've spent a ton of time researching gluten free sports supplements. My favorite protein is called Nectar and its produced by Syntrax. It's a whey protein isolate with no carbs or sugar. I'm very sensitive to the gluten content of foods, yet I can supplement my diet twice a day (pre and post workout) with the protein powder with no problems. There are a variety of flavors, and the ones that are gluten free are labeled clearly right on the front. You can find it at any Vitamin Shoppe or even online. hope this helps.
