Has anyone else's blood sugar gone up from taking Glucosamine & Chondroitin? My husband is diabetic and takes Glucophage, but he also started taking G/C. a few days ago and his sugar has been higher. Has this happened to anyone else. It could be a coincidence, but he's going to stop taking the Glucosamine/Chondroitin for a few days and see if his sugar goes down again.
