    I have used this product for almost 10 years and it has helped giving some relief to the knees. It is nice to find a company that can provide the product. When I need them.

    My hip had gradually become extremely painful. decided to try Dona after reading about it. After about a month I knew the pain was subsiding. Now there is no pain whatsoever. So happy I discovered this supplement.

    Started 2 weeks ago so too early to give a full review but the creaking in my knee has stopped and it doesn't hurt as much going up stairs. After I did my research I called my Dr. with a few different supplement ideas and she recommended this supplement over the other reviewed products.
