Victoria Primavera likes to stay active. So when she started feeling achy, she began taking nutritional supplements. Victoria Primavera "I still have pain in my joints, but it's not so bad since I've been taking the glucosamine chondroitin." "Some research suggests that the combination of glucosamine and chondroitin might reduce pain in some people who have osteoarthritis in their knees, but the evidence is still inconclusive. However, we know that a lot of people are buying these supplements, so we wanted to see whether they're getting what they're paying for." Consumer Reports tested 16 popular glucosamine-chondroitin supplements -- evaluating three different samples of each. First the samples were tested to see if they contained the amount of glucosamine and chondroitin the label indicated. And they tested for heavy metals, like mercury and lead. Jaime Kopf "Our tests show that none of the supplements contained worrisome levels of lead or other toxic metals. An all of the products contained their labeled amounts of glucosamine." But one -- Nature Made Triple Flex Triple Strength -- averaged only 65 percent of the labeled amount of chondroitin. Six others averaged 79 to 87 percent. And of the 16 tested, two did not dissolve sufficiently -- indicating the ingredients might not be fully absorbed in the body. They were the Trigosamine Max Strength and 365 Everyday Value Extra Strength from Whole Foods. However, nine did meet Consumer Reports' quality criteria. The least expensive - Kirkland Signature Clinical Strength tablets from Costco. ."
