Good stuff
I find triflex to work very well I have arthritis in my knees and I had stopped taking it for several weeks and had an increase in discomfort. After taking triflex regularly again the discomfort has definitely decreased.

Big tablets
The glucosamine/chondroitin does its job. However, in this formulary, it requires 3 rather large tablets daily. If you have any difficulty swallowing pills, this is not for you.
