Organic tart cherry comes from sour cherries (Prunus cerasus) farmed without synthetic pesticides or fertilizers. It concentrates anthocyanins and other polyphenols into a juice, powder, or capsule, and supplies a small amount of naturally occurring melatonin. Sour cherries carry more of these compounds than sweet varieties.
People often take it in the evening to ease into rest or after hard training to manage muscle soreness. Doses vary by form. Stick to the label instructions on your product.
**Key cautions:** Tart cherry can mildly thin the blood. Anyone on anticoagulant or antiplatelet medications (like warfarin, clopidogrel, or aspirin) should speak with a healthcare provider before using it. Stop taking it at least two weeks ahead of any scheduled surgery. Large servings may upset a sensitive stomach.
