Montmorency tart cherry supplementation does not improve sleep time or quality in healthy adults

In a 30-day randomized trial with 44 healthy adults, Montmorency tart cherry juice or capsules did not significantly improve sleep time or quality compared to placebo. Both groups showed increased sleep over time, but no between-group differences were observed. Body mass decreased in capsule groups, but other outcomes like body composition, cellular health, and blood pressure were unaffected.
