I took up running a few months ago but an old knee injury flared up badly and I was only able to tolerate the pain after a run with ice and an antiinflammatory. I was always limping and really believed I would have to give up running. I completed the Blackmores Bridge Run and was given some free samples of Blackmores joint formula at the finish. I also confiscated my husband and daughters supply and took them for 2 weeks. I did notice an improvement so I bought a bottle and have taken the capsules religiously for about a month now and I honestly have no pain ever after I run. I haven't had an antiinflammatory for weeks and even if I forget to ice my knee, I don't have any pain the next day!! It is a fantastic product and I reccommend it to everyone.
