What made me choose this product? The purity/quality standards and the amount of hyaluronic acid per serving. There's something special with that amount. My first dose was November 1, 2017. After 28 days of using this joint supplement: left knee doesn't hurt,crack or pop anymore and I'm able to put weight resistance again to those joints. My facet joint is continuing to feel better each day and the pain has decreased by about 50% which does wonders for my mood. I'm off the daily use of muscle relaxers, and have reduced my daily opiate pain medication by half. I actually am getting some of my life back!! Will I continue to use this joint supplement? Yes!
