Nothing ever helped but I kept trying. The apparent difference is that DONA uses crystalline versus regular glucosamine...don't know what that means, but it works. This stuff has noticeable effects: my very painful hands - especially the base of my thumbs - feel much better now. The pain was so bad that even without moving my hands the constant ache was excruciating. Now, with this DONA supplement, they only hurt slightly when I lift something the wrong way. This is a dramatic change. I noticed my pain lessening after two weeks. My husband's knee pain didn't change until he'd been on DONA for about two months now. He's just barely feeling an improvement; we'll see when more time has elapsed. It's sure worth a try. Shipping is very prompt and the oblong tablets are easy to swallow. We take two at the same time, daily with food. (I don't know if taking on an empty stomach would be a problem - I just take with food since that's easier to remember.) Review: works for me!!! - my friend told me to try and so glad i did works better than my pain pills. took a couple weeks to really kick in but i have much less pain ## Features - PROMOTE HEALTHY CARTILAGE - Crystalline glucosamine sulfate is a naturally occuring substace found in cartilage to cushion joints and bones.
