<<People tell me that alternative natural healing can give far more

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.
