G&C has been my knees' savior for about 7 years now. I once tried G & MSM and my pain partially came back, so went back to G&C.
I've had good success with Walgreen G&C, buy it on their 2 for 1 specials. But am currently taking Osteo Bi-Flex with all three plus joint fluid. Found it on a big sale and bought 3 large bottles.
This is probably our 10th or 12th thread on this same issue, over the past 2.5 years. Not surprising it is a popular topic, in a forum on 50+ cycling. There are controlled medical studies that have shown statistically significant benefits for people who have the right matching conditions.
