I had no idea that glucosamine was bad for Type 2 diabetes. I was just diagnosed in May, but it is still reversible at this point so I'm doing my best. Anyway, I can't take glucosamine either because I'm allergic to shellfish. One other supplement you may have researched that I do take- MSM. It's a biological sulfur. I've noticed it really helps me with pain, and it helps joints, the liver, and the digestive tract too.
