Ok, I'd like to share this collagen product I've been taking for about 2 yrs now. A friend put me on to it as her friends told her about it. There are 1000's of reviews online and I'm realizing now that I haven't been taking enough...suggested dose is 2T two times per day, but people do take more depending on their joint conditions. One lady on another health group takes 9T per day and claims she has no stiffness in her knees now. She worked up to this dose...I'm going to start moving up and see if I can reduce this knee stiffness and if back stiffness is reduced, even better.

Just about every online supplement company sells it and health food stores, I think...never looked for it there as online is always less cost.
I know you will all do your research. C
