I have been looking at joint supplements and noticed that there 
is a huge difference in the ingredients AND the amounts included
from one product to the next.  Yet they all claim to do the same 
thing!  hmmm. Some have glucosamine as the main ingredient with a
smaller amount of chondroitin sulfates and others are just the 
opposite.  I am looking at a catalog with 3 full pages of joint
supplements products. Does anyone have an idea of what you really
need as far as ingredient and dosage?  Thanks--Mary
