Quick Answer: Sour cherry juice -- particularly from Montmorency tart cherries -- contains natural melatonin and tryptophan that measurably improve sleep quality. A 2010 clinical trial found that 240 ml taken twice daily reduced insomnia severity and increased total sleep time by an average of 84 minutes per week.

If you have been searching for a natural way to improve your sleep without reaching for a prescription, sour cherry juice may be worth a closer look. This tart, deep-red juice has become one of the more studied food-based sleep remedies, backed by controlled trials rather than just anecdote. At Mattress Miracle, we help Brantford families improve their sleep from the ground up -- and that means looking at both the surface you sleep on and the habits that support good rest.
Why Sour Cherry Juice Works for Sleep
Sour cherries -- especially the Montmorency variety grown in North America and parts of Europe -- are one of the few whole foods that contain measurable amounts of naturally occurring melatonin. Melatonin is the hormone your brain produces in response to darkness to signal that it is time to sleep. Most adults produce less melatonin as they age, which partly explains why sleep quality often declines with age.
Sour cherry juice supports sleep through three overlapping mechanisms:
- Melatonin content: Montmorency cherries contain between 13 and 17 nanograms of melatonin per gram of fresh fruit. While this is a smaller dose than most supplements, it is delivered alongside other compounds that may enhance its absorption.
- Tryptophan: Cherries contain tryptophan, an amino acid your body converts into serotonin and then into melatonin. Tart cherry juice also contains procyanidin B-2, which is thought to inhibit the enzyme that breaks down tryptophan before it can be converted.
- Anti-inflammatory anthocyanins: The pigments that give tart cherries their deep colour are potent antioxidants. Inflammation is increasingly linked to poor sleep, and reducing systemic inflammation may help the body settle into deeper, more restorative sleep stages.
Sleep Science: Melatonin does not force sleep the way a sedative does. It shifts the timing of your internal clock, making you feel sleepy at an appropriate time. Foods that support your body's own melatonin production work with your biology rather than overriding it.
The Pigeon et al. 2010 Study
The most frequently cited clinical evidence for sour cherry juice and sleep comes from a randomised crossover trial published in the Journal of Medicinal Food in 2010. Researchers Wilfred Pigeon, Michael Carr, Colin Gorman, and Michael Perlis recruited 15 older adults with chronic insomnia and assigned them to drink either tart cherry juice or a placebo beverage for two weeks, then switch.
Participants who drank tart cherry juice showed statistically significant improvements in several sleep measures compared to placebo:
- Insomnia severity scores dropped meaningfully on the Insomnia Severity Index.
- Total wake time after sleep onset was reduced.
- The treatment group gained an average of 84 minutes of sleep per week compared to placebo.
While the sample size was small, the crossover design -- where each participant serves as their own control -- strengthens the findings. Subsequent research has supported the core conclusion: tart cherry juice has a modest but real effect on sleep quality, particularly for older adults and those with mild to moderate insomnia.
Research Note: A 2018 study published in the American Journal of Therapeutics (Losso et al.) found that Montmorency tart cherry juice increased total sleep time by 84 minutes and sleep efficiency in adults with insomnia, corroborating the Pigeon findings with a larger sample.
Dosage and Timing
The protocol used in the Pigeon 2010 trial -- and replicated in follow-up studies -- used 240 ml (approximately one cup or eight ounces) of tart cherry juice taken twice per day: once in the morning and once about one to two hours before bed. If you are comparing viral bedtime cups, our look at lettuce water and its mouse-study science makes a useful contrast.
Key points on dosage:
- 240 ml twice daily is the evidence-based dose. Taking it only at night may still be helpful, but the morning dose supports overall tryptophan metabolism throughout the day.
- Concentrate vs. whole juice: Many products sold in Canada are concentrates. If using concentrate, follow label instructions -- typically 30 ml diluted in water to achieve equivalent potency.
- Timing the evening dose: Take your evening serving 60 to 90 minutes before your target bedtime. This allows time for tryptophan conversion and melatonin release.
- Consistency matters: Benefits tend to build over one to two weeks of daily use. Do not judge effectiveness after just one or two nights.
Practical Tip: If the tart flavour is strong, dilute your sour cherry juice in an equal part of water. Avoid adding sugar, as a blood sugar spike before bed can disrupt sleep onset and overnight stability.
Montmorency vs Other Cherries
Not all cherries are equal when it comes to melatonin content. Montmorency cherries (a variety of Prunus cerasus, the sour or tart cherry species) contain significantly higher concentrations of melatonin and anthocyanins than sweet cherry varieties like Bing.
When shopping for sour cherry juice for sleep purposes, look for:
- Products labelled specifically as Montmorency tart cherry juice
- No added sugar or minimal added ingredients
- 100% juice or concentrate from tart cherries, not blended sweet cherry products
In Canada, Montmorency tart cherry juice and concentrates are available at most health food stores and increasingly at mainstream grocery retailers. Brands like Cheribundi, Dynamic Health, and Lakewood carry tart cherry juice that fits the criteria used in clinical research.
What to Expect
Sour cherry juice is not a sleep sedative. It will not knock you out or produce the heavy drowsiness that some sleep medications cause. What most people notice over one to two weeks of consistent use is:
- Falling asleep more easily (shorter sleep latency)
- Waking less often during the night
- Feeling more rested in the morning without grogginess
Dorothy, Sleep Specialist at Mattress Miracle: "I often recommend tart cherry juice as a starting point for customers who want to improve their sleep naturally. The research is solid, the risk is very low, and it pairs well with other sleep hygiene improvements -- like making sure your mattress is actually supporting your body properly."
It is worth noting that sour cherry juice is not a substitute for medical treatment of serious sleep disorders like sleep apnea or severe insomnia. If you have persistent, disruptive sleep problems, speak with your doctor or a sleep specialist.
Also keep in mind that even the best natural sleep remedy works better on a comfortable, well-suited mattress. If you are lying on a worn-out spring system or a mattress that does not match your sleep position, no amount of cherry juice will fully compensate.
Tart cherry juice before bed? Mattress Miracle at 441½ West Street in Brantford supports anything that helps you sleep better. But natural melatonin boosters work best when the physical sleep environment is already optimized. If you are drinking cherry juice and still tossing, the mattress might be undoing the benefit.

How long does it take for sour cherry juice to help with sleep?
Most clinical trials show measurable improvements after 7 to 14 days of consistent twice-daily use. Some people notice lighter, easier sleep within a few days, but the full benefit typically takes one to two weeks to develop as tryptophan metabolism and melatonin timing normalise.
Can I take sour cherry juice with melatonin supplements?
There is no known harmful interaction between tart cherry juice and melatonin supplements. However, combining them may result in more melatonin than you need, which can cause vivid dreams or morning grogginess in some people. Start with just the cherry juice before adding supplements.
Is sour cherry juice safe for seniors?
Yes, and the Pigeon 2010 trial was conducted specifically with older adults. Tart cherry juice is generally well tolerated. People taking blood thinners or medications metabolised by the liver should check with their doctor, as cherry juice can affect drug metabolism in some cases.
Does sour cherry juice have a lot of sugar?
Pure, unsweetened Montmorency tart cherry juice contains natural fruit sugars -- roughly 18 to 22 grams per 240 ml serving. This is comparable to other fruit juices. Choose unsweetened varieties and avoid those with added cane sugar, especially if you have blood sugar concerns.
Can I use tart cherry concentrate instead of juice?
Yes. Concentrate is more portable and economical. Look for products where 30 ml of concentrate is equivalent to 240 ml of juice. Dilute in water before drinking. The same Montmorency variety and no-added-sugar rules apply.
