Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Sour cherry (Prunus cerasus), especially in the form of tart cherry juice, has been investigated for its effects on sleep quality and duration. The primary mechanism believed to underlie its sleep-supporting properties is its natural content of melatonin, a hormone that helps regulate the sleep-wake cycle. Several small clinical studies have examined the impact of sour cherry or tart cherry juice on sleep in adults. For instance, randomized controlled trials have found that consumption of tart cherry juice can modestly increase total sleep time and sleep efficiency in both healthy adults and older adults with insomnia. These improvements are thought to be due to both melatonin and other phytochemicals (such as polyphenols) with potential anti-inflammatory effects that may support sleep.

While the evidence base is not large, and some studies have methodological limitations (such as small sample sizes), there appears to be moderate scientific support for the use of sour cherry for improving sleep, especially in those experiencing disturbed or restless sleep. Systematic reviews and meta-analyses suggest a positive but not dramatic effect. Traditional use of sour cherry for sleep is less well documented compared to the scientific literature. Overall, sour cherry is considered a promising but not definitive aid for sleep, warranting further high-quality research.
