🍒Cherries
One of the only foods with naturally occurring melatonin, cherries are a uniquely powerful fruit for sleep, exercise recovery, inflammation and joint health — all backed by clinical research.
What It Is
Cherries are stone fruits from the genus Prunus, available in sweet (Prunus avium) and tart (Prunus cerasus) varieties. Tart cherries in particular have been the subject of extensive clinical research and are among the most scientifically validated fruits for athletic recovery, sleep quality, and inflammation reduction.
Both varieties are rich in anthocyanins — the same antioxidant pigments found in blueberries — but cherries are unique in also containing naturally occurring melatonin, making them one of the only foods that can directly support the body's sleep-wake cycle. Tart cherry juice and concentrate are among the most studied functional food products in sports nutrition.
Nutritional Highlights
Health Benefits
- Tart cherry juice increases melatonin levels and significantly improves sleep duration in clinical studies
- Participants drinking tart cherry juice slept an average of 84 minutes longer per night in one RCT
- Also increases tryptophan availability, supporting serotonin and melatonin synthesis
Why it works: Cherries contain both melatonin and tryptophan — the precursor to serotonin and melatonin — alongside compounds that inhibit tryptophan breakdown, creating a multi-pathway sleep support effect.
- Tart cherry supplementation significantly reduces muscle soreness and strength loss after intense exercise
- Marathon runners consuming tart cherry juice recovered faster and reported less pain post-race
- Reduces exercise-induced oxidative stress and inflammatory markers including CRP and IL-6
Why it works: Anthocyanins inhibit COX-1 and COX-2 inflammatory enzymes — the same pathway targeted by ibuprofen — reducing the inflammatory response to exercise-induced muscle damage.
- Regular cherry consumption reduces gout attack frequency by up to 35% in observational studies
- Lowers serum uric acid levels — the primary driver of gout inflammation
- Anthocyanins reduce joint inflammation and associated pain in arthritis
Why it works: Cherry anthocyanins inhibit xanthine oxidase — the enzyme responsible for uric acid production — while also enhancing uric acid excretion through the kidneys.
- Among the highest anti-inflammatory activity of any fruit tested in laboratory research
- Cyanidin-3-glucoside directly inhibits NF-kB — a master regulator of inflammatory gene expression
- Regular intake associated with reduced systemic inflammation markers across multiple studies
Why it works: Cherry anthocyanins target multiple inflammatory pathways simultaneously, blocking both the production of pro-inflammatory cytokines and the enzymes that amplify the inflammatory response.
- Tart cherry juice consumption reduces systolic blood pressure in clinical trials
- Anthocyanins improve endothelial function and reduce arterial stiffness
- Potassium content supports healthy blood pressure regulation
Why it works: Cherry polyphenols increase nitric oxide bioavailability in blood vessels, causing vasodilation and reducing peripheral resistance — a direct mechanism for lowering blood pressure.
- Anthocyanins cross the blood-brain barrier and reduce neuroinflammation
- Associated with improved memory and cognitive performance in older adults
- Melatonin provides neuroprotective effects against oxidative brain stress
Why it works: Cherry polyphenols reduce neuroinflammation and oxidative stress in brain tissue while melatonin's antioxidant properties provide additional neuroprotection — particularly relevant as we age.

Safety & Considerations
- Generally safe for most people in normal dietary amounts
- Tart cherry juice is high in natural sugars — those managing blood sugar should opt for the whole fruit or concentrate diluted in water
- May interact with blood-thinning medications due to salicylate content — consult your doctor if on warfarin
- High doses of tart cherry concentrate may cause digestive discomfort in some individuals
- Those with gout should consult a healthcare provider before using cherries as a therapeutic intervention
