Whereas many research conclude that glucosamine has no advantages for osteoarthritis, others point out that it could relieve joint ache and different signs over time.

Nevertheless, these research have been probably industry-influenced since Rottapharm financed all three. At present, no massive, long-term, industry-independent research on the effectiveness of glucosamine can be found.
An unbiased evaluation of a number of high-quality research concluded that the “Rotta formulation” improved sure measures of ache and performance greater than a placebo, whereas different types didn’t present any important advantages (10).
That stated, the advantages of taking glucosamine sulfate are small and a few researchers contemplate them clinically irrelevant (11).
