Tart cherry consumption improves sleep quality and duration in adults with sleep disorders
This systematic review of seven interventional studies found that tart cherry consumption significantly improved sleep indicators such as sleep duration, efficiency, and onset time in three studies, and increased melatonin levels in three studies. The evidence is limited and heterogeneous due to variations in dose, duration, and population characteristics.
This article is automatically generated from the structured evidence profile behind the claim above. Scores reflect the quality and quantity of available research, not clinical advice.

The Claim
Tart cherry consumption improves sleep quality and duration in adults with sleep disorders
This conclusion is most relevant to: Adults with sleep disorders or sleep complaints (specific demographics not detailed in abstract).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸The Effect of Tart Cherry on Sleep Quality and Sleep Disorders: A Systematic Review. (Food science & nutrition, 2025) —
How It Works
The proposed biological pathway:
- ▸Tart cherries provide exogenous melatonin
- ▸Anthocyanins in tart cherries reduce oxidative stress and inflammation
- ▸Reduced inflammation and oxidative stress may improve sleep regulation
- ▸Result: Improved sleep quality and duration
Who Might Benefit
Evidence fit by population:
- ▸Adults with sleep disorders or sleep complaints (specific demographics not detailed in abstract)
Recommended Dose
N/A (not specified in abstract)
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Limited number of studies (only seven interventional studies included)
- ▸Large heterogeneity in dose, duration of intervention, and population characteristics
