text: It works I'm writing this review to help others.
  
  I'm an avid senior softball player at the age of 62 but I became frustrated because of knee pain which was preventing me from playing or playing with excruciating pain. I've tried many different brands and I received limited relief this Puritan brand literally worked to eliminate joint pain in my throwing shoulder and my knees it was so evident. i recall that it started working within two weeks, it's now fun and enjoyable playing w/out pain . I'm going on my second year of taking it and I'll continue for the rest of life. For me, taking two at once in the morning works.....Aloha.
