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.

Mechanism Graph

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

Limitations

  • ⚠Limited number of studies (only seven interventional studies included)
  • ⚠Large heterogeneity in dose, duration of intervention, and population characteristics
