Tart cherry extract is a concentrated form of sour cherries. It supplies natural melatonin along with antioxidant compounds called anthocyanins.
People take tart cherry extract in capsules or as a liquid concentrate. Many use it in the evening for sleep. Others take it after a workout to help with muscle soreness and recovery. Dosing varies based on the concentration and form, so check your product label for directions.
Cautions: Tart cherries contain salicylates, which can thin the blood slightly. If you take blood thinners like warfarin or have a bleeding disorder, talk with your doctor before using it. Stop taking it ahead of any surgery. Safety for pregnant or breastfeeding women has not been established.
