I am 72 years old . I have had joint problems most of my life . After 5 days on this product , the popping & cracking in my joints has almost disappeared . Improvement continues . I will use Liquid Hydraluronic Acid for the rest of my life ' By the way , I walk 10 miles a day . Joint problems were a problem , but no longer .
