Cheribundi is a not-from-concentrate tart cherry juice made from a proprietary juicing process developed by food scientists at Cornell University to yield peak antioxidant levels. Regular consumption of tart cherry juice is clinically proven to reduce post-exercise muscle soreness. Tart cherries’ anti-inflammatory benefits may reduce pain from gout and arthritis. They also contain significant levels of melatonin that is believed to promote deeper, more restful sleep.
