Glucosamine may slow arthritis patients' bone turnover

Supplementing their diet with glucosamine, people with arthritis may slow their bone turnover and help build cartilage, according to a new animal study published in Arthritis and Rheumatism.

The study by Suanne Wane and colleagues from the University of Toronto in Ontario, Canada examined a building block of proteins known as glycosaminoglycans, which the body uses to build cartilage, in rabbits with arthritis.

In the study, rabbits were given 100 mg of glucosamine a day for eight weeks and the researchers compared two groups of rabbits with arthritis, one given glucosamine and the other given a placebo for the bone turnover rates.

Wang and team found rabbits supplemented with glucosamine had a bone turnover rate around the knee joint similar to that of normal animals while untreated rabbits had a higher rate.
