"I have been drinking the tart cherry juice for about 2 years now. All I know is I no longer have aching hands and knees. My knees used to make a crunching noise when walking but that is gone now. My hands used to hurt too much to crochet. I went on vacation last year and did not take the juice with me. At the end of the week, my hands were starting to bother me. After two days home and drinking the juice again the pain went away. I swear by the juice. My son calls it the "Jesus Juice". Thanks for all your hard work in producing this wonderful product!"
