It seems like finding something to help with pain in my joints is a little like gambling. I just keep rolling the dice and hoping I will hit a jackpot that will bring pain relief. On one of my dashes through Costco I noticed a little something new on the shelves (I always check out the offerings in the supplement area where the glucosamine products are). It is called Celadrin and I bought it and have been taking it for two months. I read up on it and knew that I needed to commit to at least a month of taking it to see if it would be effective. It was worth the risk as I am feeling less pain and have more flexibility in my knees. It did take a few weeks before I noticed a significant difference. I recommend giving it a try.
