A new survey conducted by the National Health and Nutrition Examination shows that regular use of glucosamine, chondroitin, or fish oil supplements may reduce inflammation. The study was published in the American Journal of Epidemiology.
Inflammation is now recognized as a factor in cancer, cardiovascular disease as well as many rheumatoid diseases, and a large number of dietary supplements are being marketed for the purpose of reducing inflammation. Elizabeth D. Kantor, from the Division of Public Health Sciences, Fred Hutchinson Cancer Research Center, Seattle, Washington, and colleagues analyzed data on dietary supplements and hs-CRP in 9947 participants.
Researchers report that regular use of glucosamine, chondroitin, or fish oil significantly reduced serum hs-CRP by 16% to 22%, a marker of inflammation. In participants who regularly used a supplement, the researchers found hs-CRP reductions of 17% (95% confidence interval [CI], 7% – 26%) with glucosamine, 22% (95% CI, 8% – 33%) with chondroitin, and 16% (95% CI, 0.3% – 29%) with fish oil compared with participants who did not take the supplements.
