Okay, time for your input!
At my age, I have a lot of joint pain, HOWEVER, a few months ago in an article my husband read, it said: That pure dark grape juice such as Welches, one gallon to one package of Certo, drink one or two glasses a day for joint pain.
What a difference this has made in my life.
google " Certo and grape juice " for details.
For those of you who might not know what Certo is, its that stuff you make geletin with, you get it at any grocery store.
