1500 mg and 1200 mg are the magic numbers associated with joint nutrients glucosamine and chondroitin. That's because these were the doses that produced the most robust joint-rejuvenating results in research studies. So you'll see these potencies again and again in glucosamine and chondroitin in many products, but depending on what else the brand's put in there, it can take 3, 4 or more tablets to get your 1500 and 1200. NOW Foods has the right idea with this two tablet per day glucosamine chondroitin formula. Just one tablet in the day, and one tablet at night. You can do this! Start protecting your joints today if you want to enjoy a comfortable active life tomorrow - don't wait until wear and tear have worn and torn.
