Seems to help my knee
These seem to have helped my knee, which was painfully arthritic. Originally the water soluble powdered form was prescribed for me in Europe by an orthopedist. As I really don’t like taking it that way, upon my return I found the tablets and have been taking those for the last few months. I researched this formula online and research has shown it to be effective for deteriorating joints. My orthopedist in New York has been skeptical about glucosamine supplements in the past, but what the heck - for the time being I will continue taking them. These supplements are a little expensive so try different options like Subscribe and Save and ordering the larger sized bottle. Also, give it a couple months before deciding if it is helping you.

They have tested to work
My Rheumatologist suggested Dona years ago bc it was that had actual trials with positive results. Since I started taking them, I hardly feel any pain & stiffness in my ankles, knees, or hands. I feel they have helped me & i will continue to take 1500mil a day

Open Bottle
My research has concluded Crystalline Glucosamine Sulfate is the only version of glucosamine that might offer relief of the pain and/or inflammation in my beat up knee. DONA, made by Madaus GmbH and distributed in the USA by Mylan Consumer Healthcare, Inc., appears to be the best option. Unfortunately, one of the bottles I purchased had a broken seal. The plastic shrink wrap around the cap was split, and the paper/foil seal on the bottle wasn't glued down. Therefore, I do not want to risk using this supplement. There is a "Questions or Comments" number listed on the box. However, calling it only led to a lengthy, frustrating call with someone who was difficult to understand, who didn't resolve the issue and only said she would send me an email address for me to send in a receipt and photos to someone else. So far, I have yet to receive even this information. Why doesn't Mylan just put the email on the packaging? While I understand the risk the product is contaminated is low, it's not one I feel is worth taking. It appears my $35 has been completely wasted, as has the half hour it took to get to the dead end of calling the help number.
