Tart Cherry Juice for Sleep
Tart cherry juice is a natural source of melatonin and tryptophan-sparing compounds. Clinical trials show it increases sleep time by ~84 minutes in adults with insomnia.
Dosage & Timing
Evidence Strength
3/5 — ModerateMultiple small RCTs support efficacy. Pigeon et al. (2010) and Losso et al. (2018) both showed significant improvements in sleep duration and quality in older adults with insomnia.
Overview
Drink 8 oz of tart cherry juice (Montmorency variety) twice daily — once in the morning and once 1-2 hours before bed. Tart cherries are one of the few natural food sources of melatonin and also contain procyanidins that inhibit tryptophan degradation, increasing its availability for serotonin and melatonin synthesis.
How To Do It
Choose the right juice
Use 100% Montmorency tart cherry juice concentrate (not cocktail blends). Brands like CherryActive or Cheribundi are commonly used in studies.
Morning dose
Drink 8 oz (or 1 oz concentrate diluted) in the morning.
Evening dose
Drink 8 oz 1-2 hours before bed.
Allow time to work
Most studies show benefits after 2 weeks of consistent use.
The Evidence
Each claim is linked to its source study. Confidence reflects the study design — systematic reviews and RCTs rank highest.

Measurable Outcomes
Related Protocols
Blue Light Reduction
Dim lights and avoid screens 2-3 hours before bed to protect melatonin production. Use warm/amber lighting and blue-light blocking glasses if screen use is unavoidable.
Two-Week Sleep Diary
Use a simple daily sleep diary to identify sleep timing, caffeine, alcohol, naps, and wakefulness patterns.
Stimulus Control Reset
Rebuild the bed as a cue for sleep by leaving bed during prolonged wakefulness and returning only when sleepy.
Jet Lag Light Plan
Use destination-timed light, darkness, and optional melatonin planning to shift faster across time zones.
