    Dona

    Posted by Mary on 13th Sep 2020

    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.

    DONA Crystalline Glucosamine Sulfate

    Posted by Kris on 10th Aug 2020

    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.

    KEEPS ME FROM CRYING.

    Posted by Cathy, Verified DONA Customer on 3rd Apr 2017

    Keeps me from crying when I walk up stairs. True story, and I live on the 2nd floor. My doctor recommended Dona because they actually put in as much glucosamine as they say they do. A lot of brands don't, I've tried a few others and they were worthless. If it wasn't for Dona I wouldn't have been able to move in with my husband because of the stairs.

    First time I have seen a difference using glucsominer!!

    Posted by Linda, Verified DONA Customer on 15th Nov 2014

    I have just finished my first box of DONA and I can really FEEL the difference. I have osteoarthritis and I have had injections, pills, and there was no change in my condition! Since I have been taking DONA, I have much more mobility and less stiffness after only two weeks. So, I am sold on it, so far. I am very optimistic about using my second box. I really have faith in this product! Everyone should try it! I think you will be amazed as I was. And this is only the start!

    It was a very positive first interaction with this company. Their price was very competitive, they kept me updated on the status of my order, and it arrived as promised.

    Love this product!!

    Posted by Unknown on 30th Mar 2014

    I have used this stuff for years! I recommend it to everyone I know. If for some reason I am without it for a couple of days I can really tell the difference in my joints. I have RA and this was recommended to me by a Rheumatoligst. It is the best recommendation I ever received from a doctor.

    Many years of relief from Dona

    Posted by Unknown on 23rd Mar 2014

    I have used your product for many years for pain relief from arthritis and help for other chronic pain on the advice of my orthopedic surgeon who also takes Dona glucosamine sulfate. Knowing your product is pure and was a prescription medicine in Europe builds my confidence in Dona. I am a very satisfied customer!
