Can Tart Cherry Juice Promote Better Sleep?

There is no shortage of sleep aids, be they natural or chemical. That doesn’t come as a surprise, especially when you consider that an estimated 50-70 million Americans experience sleep disorders. Restless leg syndrome, insomnia, and sleep apnea, among others, can make it difficult to fall or stay asleep. Some people don’t have a sleep disorder; rather, their lifestyle or dietary habits prevent them from shutting their eyes at bedtime with ease. 

What Is Tart Cherry Juice?

Extracted from cherries from the Montmorency cherries, or sour cherries, tart cherry juice is a natural source of antioxidant compounds. According to recent medical research, tart cherries offer a list of potential health benefits. Some preliminary studies found that sour cherries may help improve exercise recovery and improve sleep. It may also reduce total inflammation in the body, although more research is still necessary on that. 

How Can Tart Cherry Juice Promote Better Sleep?

Researchers believe that tart cherry juice is a safe and effective sleep aid. The theory behind this is that tart cherries contain the following sleep-inducing ingredients:

• Tryptophan: This amino acid converts into serotonin and melatonin in the body. Both of those hormones can influence mood, behavior, and sleep cycles. 
• Melatonin: Tart cherry juice is naturally rich in melatonin, a hormone that the body naturally secretes. Researchers note that it regulates the body’s sleep cycles and many supplements that contain melatonin help increase the duration and quality of sleep. 
• Antioxidants: Naturally rich in antioxidant and anti-inflammatory compounds, tart cherry juice may help reduce muscle soreness or aches, which can make you more comfortable and relaxed during the night. 

What Does The Research Say?

Up until this point, there have only been four studies that looked at tart cherry juice’s efficacy on improving sleep. Those four studies were:

• In 2010, a study included 15 adults over the age of 65, all of whom had insomnia. They were asked to drink one cup of a tart cherry-apple juice blend or a placebo drink first thing every morning. They drank the same amount again one to two hours before bed. After two weeks, the participants who drank the tart cherry juice displayed slightly better sleep index and reduced insomnia symptoms. 
• A 2012 study included 20 volunteers, who either consumed a placebo or tart cherry juice concentrate for a week straight. Study authors noted that melatonin was significantly higher in the tart cherry juice group. Plus, they increased sleep duration and quality. 
• A two-week study from 2018 consisted of eight adults over age 50. Participants who drank 240 milliliters (ml) of tart cherry juice twice per day sleep more than participants who drank a placebo. 
• In 2022, study authors followed 19 elite female field hockey players for five days. They were separated into two groups, one of which consumed 200 ml of tart cherry juice in the morning and 200 ml in the evening. The other group consumed the same amount of a placebo. The group that consumed tart cherry juice experienced improved sleep quality. 

How Much Should You Drink For Better Sleep?

If you are interested in experimenting with tart cherry juice for better sleep, you can start out with the doses from the aforementioned studies. Most of the referenced studies instructed participants to consume two eight-ounce servings of tart cherry juice per day. The participants drank one glass in the morning and one glass in the evening. When you buy tart cherry juice, make sure to get the one without added sugar. Consuming sugar before bedtime will interfere with sleep, rendering the cherry juice ineffective. If you want to try tart cherry juice in powder or pill form, you can take about 480 milligrams (mg) per day. 

The last thing to remember is that most of the participants in the studies experienced improvements after supplementing with tart cherry juice for seven to 10 days. If you do not see results after two weeks, you can assume that tart cherry juice is not the right sleep aid for you.
