Solgar Glucosamine/Chondroitin/MSM combines the three most researched joint-support nutrients in one product - glucosamine and chondroitin for cartilage structure, plus MSM for comfort and mobility. The 180-count size works out to a better per-dose value if you're committing to it long-term, which is really the only way joint supplements show their benefit. Give it 4-8 weeks before judging results, and check with your doctor first if you're on blood thinners or have a shellfish allergy.
