1. Is Glucosamine Really Effective?

There are various forms of glucosamine in the market. Only glucosamine in the form of glucosamine sulfate has been shown to be effective in reducing in pain and improving joint function for patient with osteoarthritis when compared with placebo. However, study results were not consistent. Most studies used preparations of glucosamine sulfate marketed in Europe by Rotta pharmaceutical company. Subgroup analysis showed that the Rotta preparation is more effective over placebo, whereas non-Rotta preparations did not. While studies have yet to ascertain that glucosamine is helpful, studies had showed that it is not harmful when taken at the recommended dose of 1500mg per day.

For consumers, glucosamine is safe to be taken as a supplement, but if you don’t experience any improvement after 3 months, you may consider switching brand or stopping taking it.
