Scroll through wellness content right now and tart cherry juice keeps surfacing as the drink of the moment for anyone chasing better sleep. The interest is not just marketing. Registered dietitians and a handful of small clinical studies point to real compounds in the fruit that may influence how the body settles down at night, which is why the humble bottle of Montmorency juice has become a fixture on wellness nightstands.
For readers weighing whether to add another pricey drink to their routine, the science offers a measured yes, with caveats worth understanding before the first sip.
How Tart Cherry Juice May Support Sleep
Tart cherries, especially the Montmorency variety, contain small amounts of naturally occurring melatonin, the hormone the body uses to signal that it is time to wind down. Drinking the juice can slightly raise melatonin availability. The fruit also contains compounds that may help support levels of tryptophan, an amino acid the body converts into serotonin and then melatonin.
That layered effect is why dietitian Debbie Petitpain, MBA, RDN, told Martha Stewart the drink’s potential comes from a combination of melatonin, anti-inflammatory effects and support of the body’s natural sleep processes rather than any single ingredient.
You also do not need much. Most studies used about 8 ounces of 100 percent tart cherry juice, usually consumed in the evening. Petitpain says drinking it consistently over time likely matters more than a single serving, because the potential benefits tend to show up only after regular use.
What Studies Say About Tart Cherry Juice and Sleep
The research base is small but consistent. In a small study of adults with insomnia conducted by researchers at the Louisiana State University Agricultural Center and Pennington Biomedical Research Center, drinking tart cherry juice was associated with about 84 additional minutes of sleep per night compared with placebo.
A separate small study of older adults with insomnia linked tart cherry juice to better sleep quality and fewer insomnia symptoms. Researchers suggested the effects may relate to tart cherries’ natural melatonin content and anti-inflammatory compounds, though they cautioned that larger trials are needed to confirm the findings.
Mackenzie Burgess, RDN, a registered dietitian nutritionist and recipe developer at Cheerful Choices, spoke with Lauren Thomann for Real Simple about the appeal. “Tart cherry juice is naturally rich in antioxidants, which studies show may help increase sleep time and efficiency,” Burgess said.
Search interest in sleep supplements has spiked as more people look for alternatives to prescription sleep aids and endless doomscrolling.

How to Try Tart Cherry Juice for Sleep
If you want to test it, look for 100 percent Montmorency tart cherry juice rather than sweetened cocktails or blends. Aim for roughly 8 ounces in the evening, in line with the amounts used in the studies. Petitpain notes that consistency likely matters more than any single pour, so a nightly routine is more likely to show results than an occasional glass.
None of this makes tart cherry juice a replacement for treating chronic insomnia. Researchers behind both small studies have called for larger trials, and dietitians frame the drink as a supporting player rather than a cure. Anyone struggling with persistent trouble sleeping should raise it with a doctor before betting on a nightly bottle.
