Consumer Reports: Glucosamine supplements

Posted: Updated:
MEMPHIS, TN -

(WMC-TV) - Some doctors say nutritional supplements can help with arthritis pain. 

Chief Consumer Investigator Andy Wise looked into more than a dozen supplements to test which relieve join pain the best. 

Victoria Primavera says she likes to stay active, so when she started feeling achy she began taking nutritional supplements.  However, she still has paint in her joints, but not nearly as bad.  She credits glucosamine chondroitin.

Jamie Kopf with Consumer Reports says there is some research to back up her claim, however most research has come back inconclusive.  We know that a lot of people are buying these supplements, so we wanted to see whether they are getting what they paid for. 

Consumer Reports tested 16 popular glucosamine-chondroitin supplements evaluating three different types 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 with Consumer Reports says their tests show that none of the supplements contained worrisome levels of lead or other toxic metals.  And all of the products contained their labeled amounts of glucosamine.

However, only one, Nature Made Triple Flex Triple Strength, averaged 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 into the body.  They were Trigosamine Max Strength and 365 Everyday Value Extra Strength from Whole Foods.

Nine of the tested products did Consumer Reports' quality criteria.  The least expensive were Kirkland Signature Clinical Strength from Costco.
