Has anyone tried the Supple drink for arthritis, if so what were your results?

I give my son a drink from Walgreen's called Joint Juice, it comes in 6 packs of small cans his knees and joint hurt him daily, he says it works and the only thing that does. It has glucose in it there is also packets you can by of similar products, with this ingredient with more quantity. I also heard Sam-E was good.
