Her dosage is (max.) 500mg.
Glucosamine, and 200 Chondroitin. I found a supplier of
tablets (a reputable shop ) on ebay UK where the tablets only contain these two supplements, and in this amount (apart from a few usual things which are added to pills in manufacture, and these substances are harmless enough to her, I checked this with the vet) Occasionally I have to buy tablets which contain Glucosamine 500 and Chondroitin a slightly lesser amount.
