Have taken it daily for several years, "in case" it has a benefit. I can't ascribe any specific relief to it and wonder whether it's just superstitious behavior on my part. My mother had rather severe arthritis, beginning at a younger age than my current tally, and my father developed it later in life as well, so I'm willing to continue with my supersition, at least until somebody completes a study concluding it makes one's toenails drop off or somesuch.

[This would be a great time for my standard rant on how the "supplement" industry remains basically unregulated and under studied, so they're free to make wild claims with abandon, but I'm an adult so no rant.]

I know this much: I have plenty of body parts that hurt from time to time for no good reason, other than harvesting the mistakes of my impetuous youth (yut).

Cheers,
