Tart Cherries

"Tart cherry extract is an excellent source of flavonoids, which
help strengthen the capillaries, collagen, eyes, joints and arteries.
The anthocyanidin and proanthocyanidin flavonoids in cherries help fight
free radical damage in the body. Tart cherry extract also has anti-
inflammatory benefits. It is well accepted as a supplement for gout, but
most of us don't realize that cherries also help decrease inflammation
in the body (not just joints). Add in the collagen support, and you are
getting a double benefit for your joint health issues."
