<<People tell me that alternative natural healing can give far more better results, but no-one seems to know what exactly would be a good treatment.>> Chondroitin does indeed suport your body's ability to repair cartilege. It does not affect blood sugar. As far as people not being able to tell you exactly what would be a good treatment - this is because different people respond differently to the same treatment. This is not unlike some people finding a pharmacetical drug helpful, while others with the same condition get less or no help from it. Siobhan
