Tart Cherry's Sleep Reputation Isn't Its Strongest Evidence

Montmorency tart cherries are one of the few natural foods that contain measurable melatonin, and they're rich in anthocyanins that work through an anti-inflammatory pathway similar to over-the-counter NSAIDs. That's produced two separate research threads — sleep and exercise recovery — and they don't have equally strong evidence behind them.

What the sleep research actually shows

A January 2025 systematic review examined seven interventional studies on tart cherry and sleep. Three reported significant improvements in sleep duration, efficiency, or onset time, and three found increased melatonin levels after tart cherry intake.¹ But a 2022 trial testing 30 days of Montmorency tart cherry in healthy adults — people without existing sleep problems — found no measurable sleep effect at all. The pattern across the research: benefits show up most reliably in people who already have poor sleep, not as a universal nightly effect.

The stronger, more consistent evidence: exercise recovery

Multiple meta-analyses — 2021, 2022, and 2023 — found small-to-moderate but consistent benefits for reducing exercise-induced muscle soreness and lowering inflammatory markers like CRP after tart cherry supplementation.² This is described in the research literature as the single most robust body of evidence for tart cherry of any kind, sleep included.

The practical takeaway

• If you're already a poor sleeper, tart cherry has some real (if inconsistent) trial support
• If you're using it as a general "sleep aid" despite already sleeping fine, the evidence doesn't back that use case well
• Post-workout is the better-supported reason to reach for it — the recovery research is more consistent than the sleep research
