    Need this product for my OA.

    Posted by iHerb Customer on Sep 28, 2017 | Verified Purchase

    Have been relying on NAG along with Glucosamine and Chondroitin Sulfates for many years with great results. Much preferred when NAG was available in 250 mg. dose for taking 2 x day more easily. The 500 mg. dose is not as convenient but is still a must have for me.

    This is a quality product. I have researched others. This one has fast and efficient transport. It works. The Tabs are even chewable for an option and have a decent taste. Great for repair and less pain of tissue.

    The body is able to meet its need for amino sugars under normal circumstances; but as the body ages, this changes. Research has revealed that under a variety of less-than-optimal conditions, the body's production of amino sugars - and their assembly into larger molecules - may be impaired. These conditions can include surgery and/or surgical recovery, severe stress, burns and major injuries, as well as aging. - - - - - - - - By supplementing your diet with N-A-G, there are key advantages that may be obtained. Numerous steps in the conversion of glucose and amino acids to amino sugars are eliminated. Amino sugar production may be enhanced. Tissue-building properties may increase.
