New population research shows that taking both glucosamine and chondroitin supplements is associated a reduced risk of developing colorectal cancer. Data from two cohort studies evaluated glucosamine and chondroitin use from 2002 to 2010. One study included female nurses 30-55 years-old, and the second included male health professionals 40-75 years-old. Accounting for other factors, including sex, BMI and physical activity, taking both supplements regularly was linked to a 23% reduced risk of developing colorectal cancer. Use of either chondroitin or glucosamine alone was not associated with a significantly reduced risk of colorectal cancer. Study authors hypothesized that the anti-inflammatory effects of glucosamine and chondroitin might reduce cancer risk.
