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!!

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!

The recommended daily dose is 1500 mg taken once-a-day - which is equal to 2 DONA caplets once-a-day. Caplets are available in bottles, with the caplets loose in a bottle.
