Quick Take

Worth trying for athletes seeking faster recovery or adults with occasional sleep issues; effects are modest.

Tart cherry extract comes from Montmorency sour cherries (Prunus cerasus), a bright-red fruit rich in anthocyanins and polyphenols. It also provides trace amounts of natural melatonin and tryptophan. The primary mechanism involves anthocyanins reducing oxidative stress and modulating inflammatory pathways such as COX activity, which may attenuate exercise-induced muscle damage and joint inflammation. Evidence-backed benefits include faster recovery of muscle strength after strenuous exercise, modest improvements in sleep duration and quality, and potential relief of osteoarthritis discomfort.

02
Improves sleep quality
03
Lowers serum uric acid
04
May reduce osteoarthritis pain
05
May lower inflammatory markers
06
May improve endurance performance

Protocol

Amount
500-1000 mg
Frequency
Once or twice daily
When
Evening, 1-2 hours before bed for sleep; pre-workout or post-workout for recovery benefits.

Onset Time

2-7 days for exercise recovery benefits; 1-2 weeks for sleep effects.

Who Should Consider

Endurance or strength athletes
Adults with disrupted sleep patterns
People with osteoarthritis knee pain
Individuals with elevated uric acid or gout risk
Older adults with muscle recovery concerns

Food Sources

  • Montmorency tart cherries, fresh or frozen (~50-80 mg anthocyanins per 100g)
  • Tart cherry juice, unsweetened (~300-600 mg anthocyanins per 240 mL)
  • Dried tart cherries (concentrated sugars, lower polyphenol density by weight)

How It Works

Anthocyanins and other polyphenols in tart cherry inhibit cyclooxygenase enzymes and scavenge reactive oxygen species, dampening exercise-induced inflammation and muscle protein breakdown. The natural melatonin and tryptophan content may also support sleep-wake regulation by influencing melatonin receptor activity and serotonin metabolism.
