DONA contains crystalline glucosamine sulfate, a naturally occurring substance found in cartilage to cushion joints. DONA helps in maintaining cartilage health so that you can actively participate in daily activities. What is Glucosamine? Glucosamine is a natural sugar made by the body and is responsible for the maintenance and synthesis of cartilage. Cartilage is present between joints and acts as a cushion between the joint bones, to maintain joint comfort and mobility. What is Crystalline Glucosamine Sulfate? Crystalline Glucosamine Sulfate is a specific Glucosamine Sulfate stabilized in the sodium chloride stabilization and is used in the DONA brand. It is used to identify the specific version used within DONA and within its major studies. How Crystalline Glucosamine Sulfate Works? Crystalline Glucosamine Sulfate provides a base for the production of glycosaminoglycans and proteoglycans, which are the building blocks of cartilage. It may act by managing the breakdown of muscles and cartilage around joints. When Should I Take DONA? DONA can be taken at any time of the day.

The one positive trial was by the Mayo Clinic. Well actually, it is two trials. They did a 3 year trial that showed Dona Glucosamine Sulfate helped, particularly with arthritic knees. Since they had several trials with glucosamine that did not have positive results, they repeated the test and again got positive results. They write that they don't know why this product seems to be effective when the other glucosamine have not. They theorize that it is either the quality since this brand is pharmaceutical quality versus the others they tested were not or it is that the Dona caps include sulfate which their other tests did not. I decided it doesn't matter which theory is correct. Dona caps worked in their trials. My knees were hurting so bad that I had trouble with stairs and my knee didn't hold me one time and I fell down the steps. I went to the Dr and found that I have less than 10% cartilage remaining. He gave me a steroid shot in each knee and said it might or might not work and that I'd likely need surgery before too long. The shots helped but I also started taking Dona caps to try to delay the surgery. I went in for my 6 month follow up and surprised the Dr. He pointed out that my swelling had not yet returned but the steroid shot should have been worn off. He thought the swelling should have returned. I told him "No, the swelling hasn't returned and I have no pain when I walk up or down stairs." He was pleased and told me to continue doing whatever I was doing. I mentioned glucosamine and he shrugged and said "If it works for you, go ahead." But when I mentioned that this particular brand had positive trials at the Mayo Clinic, he stopped me and wrote down the brand so he could investigate. My knees continue to feel fine, so I haven't seen him again. When I do, I will see what his research shows. My aunt has now started with these capsules and she reports some improvement, but not as significant as mine. ### ⭐⭐⭐⭐⭐ IT WORKS!!! *by on Reviewed in the United States September 30, 2018* I have been diagnosed with severe spinal stenosis and severe arthritis in my back, which makes surgery not an option. An old friend (a retired oncologist) and I were discussing our health problems, which turned out to be identical. He told me to use Dona, it was very important! I asked him what it was and when he said glucosamine sulfate, I laughed and said I'd been taking it for over 40 years! "Not like this!" he said and explained that it was pharmaceutical grade and in crystalline form. I was in terrible physical shape at the time, unable to straighten up until I had been up for 4 or 5 hours. My back pain was incessant. I said I would try anything. I immediately went home and ordered the Dona from Amazon. Because of severe reactions to prescription arthritis medicine I was surviving on Aleve and it was tearing up my stomach. I put the Dona in with my other vitamins and herbs and forgot about it. About 10 days later, I noticed a small improvement in my back. Then the next day a little more improvement. This continued by small degrees. When I refilled my vitamins I realized it was the Dona. As the weeks passed, I continued to improve and now I am pain free (if I use good sense) and am riding and doing ranch work again. I am 76 years old. I also take turmeric. ### ⭐⭐⭐⭐⭐ Great Product *by on Reviewed in the United States May 13, 2026* Incredible product and I have it delivered each month.
