Chondroitin

Chondroitin is a natural powder supplement for arthritic help and joint inflammation. This chondroitin is manufactured using fish cartilage (shark) vs bovine cartilage. Chondroitin is most often used with Glucosamine HCL. There is also anecdotal evidence for tumor reduction and allergies. 

One half (1/2) of a teaspoon equals 1650 mg - which is the daily dose for a dog 50 lbs and over.
