$43 for a 32 day supply, assuming your taking it every day works out to about $1.40 a day. I was told after 2 months to stop taking for a while until you feel problems again.
I am about 2 weeks into a 2 month cycle and already noticed my knees are quieter now. I really do not have any pain so this is more preventative for me. The knees make to o much noise to be o.k.
