Tart cherry and exercise recovery
Tart cherries (often the Montmorency variety) are rich in anthocyanins, the polyphenols responsible for their deep red color, which have antioxidant and anti-inflammatory properties. Tart cherry juice or concentrate has been studied around strenuous, especially eccentric, exercise (such as downhill running or heavy resistance work) for its effect on delayed-onset muscle soreness (DOMS) and recovery.
What the evidence supports
Across several small trials and reviews, tart cherry supplementation is associated with modest reductions in perceived soreness, some markers of inflammation and oxidative stress, and faster recovery of strength after demanding exercise. Effects are generally described as small to moderate and somewhat inconsistent, and benefits appear clearest when supplementation begins a few days before and continues around the bout.
One nuance: blunting the inflammatory and oxidative response may slightly interfere with some training adaptations, so routine use is not universally recommended. This is general information, not medical or supplement advice; consult a qualified professional before adding supplements, particularly alongside medications.
