Supplements prove ineffective
Sept. 30, 2008 For two years, doctors at the University of Utah School of Medicine studied the supplements. They say there is no evidence they slow disease. The popular combination tablet Glucosamine Chondroitin Sulfate is the sixth-top selling supplement. It had annual sales of $831 million in 2007, according to the Nutrition Business Journal. Some doctors would like to see more research. Others say they won't recommend the supplement anymore unless patients believe they work. The study was funded by the National Center for Complementary and Alternative Medicine at the National Institutes of Health.
