Tart cherry juice is juice made from sour cherries, a fruit distinctly different from the sweet cherries you’d find in a grocery store produce section. It has a sharp, tangy flavor and a deep red color, and it’s gained popularity as a functional drink linked to better sleep, exercise recovery, and reduced inflammation. Most commercial tart cherry juice comes from Montmorency cherries, which have bright red skin and clear flesh, though some is made from Balaton cherries, a darker, more burgundy variety with a slightly sweeter flavor profile.
What Makes It Different From Sweet Cherry Juice
Tart and sweet cherries are actually two different species. The key differences go beyond taste. Tart cherries contain higher amounts of vitamin A, beta-carotene, and total polyphenols (plant compounds with antioxidant activity) than sweet cherries. Sweet cherries, on the other hand, contain more anthocyanins, the pigments responsible for deep red and purple colors in fruit. Tart cherries are also notably higher in hydroxycinnamates, a type of antioxidant compound, while sweet varieties like Bing cherries are richer in a different class of antioxidants called flavan-3-ols.
This higher concentration of certain plant compounds is the main reason tart cherry juice, not sweet, is the one studied for health benefits. You’ll rarely find fresh tart cherries in stores because they’re too sour to eat on their own. Instead, they’re processed into juice, concentrate, dried fruit, or powder.
Nutrition in One Cup
An 8-ounce (236 mL) serving of unsweetened tart cherry juice contains about 159 calories and 36.9 grams of carbohydrates, nearly all of which come from natural sugars. That sugar content is comparable to orange juice or grape juice, so it’s worth factoring in if you’re watching your intake. The juice also contains small amounts of melatonin (roughly 0.135 micrograms per 100 grams of cherries) and the amino acid tryptophan, which your body uses to produce both melatonin and serotonin.
Sleep Benefits
Sleep improvement is probably the most well-known reason people reach for tart cherry juice. The mechanism involves two things working together: the melatonin in the juice helps regulate your sleep-wake cycle, while tryptophan gives your body raw material to make more melatonin and serotonin on its own. What makes tart cherries particularly interesting is that they contain enzymes that slow the breakdown of tryptophan in your body, keeping it active longer. That can help you fall asleep faster and stay asleep.
Small studies suggest tart cherry juice can improve both sleep duration and quality, particularly in people who already have trouble sleeping. The effects are modest compared to a sleep medication, but for people looking for a food-based approach, the evidence is more consistent here than for most other natural sleep aids.
For sleep, the typical approach used in studies is 30 mL (about 1 ounce) of tart cherry juice concentrate or 237 mL (8 ounces) of regular tart cherry juice, taken twice a day. One dose in the morning and a second dose one to two hours before bed.
Exercise Recovery
Athletes and regular exercisers are another major audience for tart cherry juice. The idea is that its antioxidant compounds reduce muscle soreness and speed recovery after hard workouts. Study protocols typically have people drink tart cherry juice daily for three to seven days before a hard exercise session, then continue for two to four days afterward.
The evidence here is more mixed than the marketing suggests. A 2025 study on repeated sprint exercise found no significant changes in key inflammatory markers (C-reactive protein, IL-6, or TNF-alpha) between people taking tart cherry supplements and those taking a placebo. Some earlier studies have reported reductions in perceived muscle soreness, but the objective blood markers don’t always move in the same direction. If you’re an endurance or strength athlete, tart cherry juice isn’t likely to hurt recovery, but it may not deliver the dramatic anti-inflammatory effect some brands promise.
Gout and Joint Inflammation
Tart cherry juice has a longer history as a folk remedy for gout, and there’s some real science behind it. A case-crossover study of 633 gout patients found that cherry consumption was associated with a 35% reduction in the risk of gout flares. Gout is driven by uric acid crystals building up in joints, and the anti-inflammatory compounds in tart cherries appear to help manage that process. Many people with gout drink tart cherry juice daily as a complement to their standard treatment, though it isn’t a replacement for prescription gout medication in moderate to severe cases.
How Much to Drink
Tart cherry juice comes in two forms: regular juice and concentrate. The concentrate is thicker, more potent per ounce, and lower in volume per dose.
- Concentrate: 30 mL (1 ounce) twice daily, totaling 60 mL per day. This is the most practical option since it’s a small amount you can mix into water or take straight.
- Regular juice: 237 to 355 mL (8 to 12 ounces) twice daily, totaling 474 to 710 mL per day. This adds up to significant calories and sugar over the course of a day.
If you’re using it for sleep, timing matters: one dose in the morning and one dose one to two hours before bed. For exercise recovery, start supplementing several days before a hard event and continue for a few days after.
Side Effects to Know About
Tart cherry juice is generally well tolerated, but it contains sorbitol, a naturally occurring sugar alcohol found in cherries. Sorbitol can cause stomach pain, gas, diarrhea, and occasionally nausea in some people, especially at higher doses. If you have a sensitive digestive system or irritable bowel syndrome, start with a smaller amount and see how you react.
There’s also some evidence that tart cherry juice may interact with blood-thinning medications. If you take blood thinners, it’s worth discussing with your prescriber before adding it to your routine. And because even unsweetened tart cherry juice delivers close to 37 grams of carbohydrates per cup, people managing blood sugar should account for it the same way they would any other fruit juice.
