*3.4. Tart Cherry Juice*

Interventions utilizing tart cherry juice resulted in a universal increase across studies in TST (range from 29–39 min). The studies also showed modest improvements in SE (2.7–3.7%), and slight reductions in SOL (3.6–9.1 min) and WASO (16.8 min). The tart cherry juice studies were all performed in general population cohorts (both healthy and poor sleepers).
