Tart Cherry for Recovery: What the Sports Science Says

← Back to articles

Tart cherry (Prunus cerasus), and the Montmorency variety in particular, has become one of the more credible natural recovery aids in sports nutrition. Unlike many "natural anti-inflammatory" supplements that lean on cell-culture data, Montmorency tart cherry concentrate has been tested in well-designed human exercise-recovery trials — in marathon runners, strength athletes, and resistance-training protocols — with consistent positive results for muscle soreness, inflammation markers, and oxidative stress.

Marathon and Exercise Recovery Trials

Howatson and colleagues (2010, Scandinavian Journal of Medicine & Science in Sports; PMID 19883392) gave 20 recreational marathon runners Montmorency tart cherry juice or placebo for 5 days before, the day of, and for 48 hours after a marathon. The cherry group recovered isometric muscle strength faster, had significantly lower inflammation (IL-6, CRP, uric acid), and showed less oxidative stress (lower TBARS at 48 h, higher total antioxidant status). Bowtell et al. (2011, Medicine & Science in Sports & Exercise; PMID 21233776) tested Montmorency cherry concentrate in 10 well-trained men doing intensive single-leg knee-extension exercise (10 sets of 10 reps at 80% 1RM). Maximal voluntary contraction recovered faster at 24 and 48 h with cherry, and oxidative damage (protein carbonyls) was lower.

The Anti-Inflammatory Mechanism

Tart cherries are rich in anthocyanins (cyanidin and peonidin glycosides) and other polyphenols that inhibit cyclooxygenase-1 and -2 (COX-1, COX-2) — the same enzymes targeted by ibuprofen and aspirin, though much less potently. Cell-based work by Seeram and colleagues at Oregon Health & Science University placed cherry anthocyanin anti-inflammatory activity in the same general range as a standard ibuprofen dose. The advantage over NSAIDs for athletes is that cherry anthocyanins do not appear to blunt the adaptive response to training the way chronic NSAID use can.

Sleep Quality and Natural Melatonin

An unexpected line of research is sleep. Montmorency cherries are one of the few natural food sources of melatonin (roughly 13 ng/g). Howatson et al. (2012, European Journal of Nutrition; PMID 22038497) gave 20 healthy adults 30 mL of tart cherry juice concentrate twice daily for 7 days; total urinary melatonin rose significantly, and total sleep time and sleep efficiency improved versus placebo. A separate pilot in older adults with insomnia (Pigeon et al., 2010, Journal of Medicinal Food; PMID 20438325; n = 15, crossover) showed a significant reduction in wakefulness after sleep onset versus placebo, although other sleep measures (latency, total sleep time, efficiency) did not separate significantly. The sleep effect is real but modest compared with exogenous melatonin.

Dosing and Practical Use

The effective dose in the trials is about 30 mL of Montmorency concentrate twice daily, or 8–12 oz of juice twice daily, starting 4–5 days before the bout and continuing 2–3 days after. Capsulated powdered tart cherry extract (480–1,000 mg/day) has also shown effects, but with fewer trials. Pre-loading matters: a single post-exercise dose does not reproduce the multi-day protocol. Tart cherry combines well with sleep, protein, and other recovery basics, and does not interact with common medications at typical doses.
