Tart Cherry for Better Sleep: What Science Really Says
Tart cherry has gained popularity as a natural sleep aid, with many claiming it helps improve sleep quality. But what does the medical evidence actually say? Let's dive into the science behind this superfood and whether it truly deserves a place in your bedtime routine.
What Makes Tart Cherry Special for Sleep?
Tart cherries, also known as Montmorency cherries, contain naturally high levels of melatonin - the hormone that regulates your sleep-wake cycle. Unlike sweet cherries, tart varieties pack significantly more of this sleep-promoting compound.
Research published in the Journal of Medicinal Food found that tart cherry juice contains melatonin concentrations ranging from 13.46 to 0.14 ng/mL, depending on the variety. This is notably higher than most other fruits and vegetables.
Key Finding:
Studies show that consuming tart cherry juice can increase your body's melatonin levels by up to 85%, potentially improving both sleep duration and quality.
The Scientific Evidence
A landmark study from Louisiana State University examined 7 older adults with insomnia who drank 8 ounces of tart cherry juice twice daily for 2 weeks. The results were promising:
- •Sleep time increased by an average of 84 minutes
- •Sleep efficiency improved significantly
- •Participants reported feeling more rested upon waking
Another study published in the European Journal of Nutrition found that tart cherry juice consumption led to significant increases in sleep time and sleep efficiency in adults with chronic insomnia.
However, it's important to note that most studies have been small-scale, and larger clinical trials are needed to confirm these findings conclusively.
Beyond Melatonin: Other Sleep-Promoting Compounds
Tart cherries don't just rely on melatonin for their sleep benefits. They also contain:
Tryptophan
An amino acid that helps produce serotonin and melatonin in your body
Anthocyanins
Powerful antioxidants that reduce inflammation and may improve sleep quality by reducing pain and discomfort
Procyanidins
Compounds that may help prevent the breakdown of tryptophan, allowing more to be converted into serotonin
This combination of compounds creates a synergistic effect that may be more powerful than melatonin alone.
How to Use Tart Cherry for Sleep
If you want to try tart cherry for better sleep, here's what the research suggests:
Timing
Drink 8 ounces of tart cherry juice or concentrate twice daily - once in the morning and once 1-2 hours before bedtime
Consistency
Benefits may take 3-7 days of regular consumption to appear. Be patient and consistent
Form
Choose 100% tart cherry juice or concentrate without added sugars. Fresh or frozen tart cherries can also work, though juice provides more concentrated benefits
Amount
Most studies used approximately 240 mL (8 oz) servings containing the equivalent of 90-100 tart cherries
Important Considerations and Side Effects
While tart cherry juice appears safe for most people, there are some things to keep in mind:
Tart cherry juice contains natural sugars - about 25g per 8 oz serving. Those with diabetes should monitor blood sugar levels carefully
Each serving adds approximately 140 calories to your daily intake
Tart cherry may interact with blood thinners and certain medications. Consult your doctor if you're on prescription medications
Some people experience mild digestive upset when first consuming tart cherry juice
It's also worth noting that tart cherry is not a magic solution. While it may help improve sleep, it works best as part of a comprehensive sleep hygiene routine.
Who Might Benefit Most?
Research suggests tart cherry may be particularly helpful for:
- ✓Older adults with age-related sleep difficulties
- ✓People with mild to moderate insomnia
- ✓Athletes looking to improve recovery sleep after intense training
- ✓Those seeking natural alternatives to melatonin supplements
However, if you have severe insomnia or diagnosed sleep disorders, tart cherry should complement, not replace, professional medical treatment.
The Bottom Line
The medical evidence supporting tart cherry for sleep is promising but still emerging. Studies consistently show improvements in sleep duration and quality, likely due to its natural melatonin content and anti-inflammatory compounds.
While it's not a miracle cure, tart cherry juice appears to be a safe, natural option worth trying as part of a healthy sleep routine. Just remember to choose unsweetened varieties, be consistent with consumption, and maintain good sleep hygiene practices.
If you decide to try it, give it at least a week of regular use before evaluating its effectiveness. And as always, consult with your healthcare provider if you have any concerns or underlying health conditions.
