What Is Tart Cherry?

As the name implies, tart cherry is a type of cherry, scientifically classified as Prunus cerasus. It's the deep red cherry that tastes sour; hence they're also known as sour cherries. Of those, Montmorency tart cherry is the most popular type grown in the U.S. and potentially the most beneficial.

Types of Tart Cherry Products

Tart cherry products come in a wide variety of forms, making it easy to find an option that fits your lifestyle and preferences. Prized for its rich flavor and considerable concentration of beneficial compounds, Montmorency tart cherry is most commonly used in these products.

One of the most renowned choices is tart cherry juice, which is enjoyed both on its own and as part of a tart cherry juice blend. You’ll also find tart cherry juice concentrate, which can be diluted with water or added to smoothies for a potent boost, as well as tart cherry powder, which is perfect for mixing into shakes or recipes.

And if you enjoy baking or cooking, sour cherries or tart cherry juice can add a tangy twist to your favorite baked goods or dishes, while still delivering the wellness benefits associated with tart cherry.

For those seeking to maximize convenience and minimize sugar intake, tart cherry capsules offer a simple way to get the benefits of tart cherry without drinking tart cherry juice.

Tart cherry fruit extract is another concentrated option, often found in nutritional supplements.

What Are Tart Cherry Supplements?

Tart cherry supplements come in various forms, including capsules, tablets, and powders, all featuring extracts of tart cherry.

Capsules are a convenient and easy-to-swallow option, whereas powders can be mixed with water or juice. Some supplements may also include other herbal supplements or vitamins.

You’ll see tart cherry supplements marketed for everything and anything—and it’s crucial to keep in mind that not all uses have a scientific basis. Anecdotal evidence may suggest potential benefits that science hasn't yet determined.

However, it's also worth noting that research into tart cherry is ongoing and new discoveries are being made every day.

For now, though, we’re going to err on the side of caution and only cover the potential benefits and uses of tart cherries that have been studied and show promise.

Why Is Tart Cherry Extract So Popular?

Tart cherries are packed full of useful nutrients—we're talking vitamins, minerals, essential amino acids, and even melatonin (the sleep hormone).

Tart cherries contain vitamin A, vitamin B6, and vitamin C, as well as the minerals potassium and magnesium, which are essential nutrients in food. Again, tart cherries have more of these than sweet cherries, including 20 times more vitamin A. (1)

They're also a strong source of fiber, which may help keep you fuller for longer—useful if you're on a diet.

But it's the antioxidant and inflammation-soothing qualities that really give tart cherries their healthy punch. Scientists have found they may offer protective benefits that could promote cardiovascular health, lower blood pressure, soothe joint aches and stiffness, ease muscle soreness, help sleep, reinforce memory, and more. (2, 3)

Let's examine the science behind each potential benefit and use.

The Benefits and Uses of Tart Cherry Supplements

In the interest of full disclosure, we should point out that some of the scientific trials we’re mentioning use cherry juice or a concentrated cherry beverage, while others use the powdered version—likely what you'd find in tart cherry pills or capsules.

Studies don't seem to show a great difference between the two; they are similarly beneficial, which is great news for those who don't want to drink sour cherry juice and would prefer capsule or pill form instead.

So, let's take a look at what science says about the potential benefits of tart cherries....

Joint Health

If you contend with stiff and achy joints, you may have already heard of tart cherry. The lovely pigments that give cherries their deep red color (also known as anthocyanins) act as potent antioxidants and help to modulate inflammation.

Antioxidants tackle free radicals that cause damage to cells and tissues in the body. As such, they work against oxidative stress and discourage inflammation. (4)

It's important to note that acute short-term inflammation is often a reaction to injury, where the body seeks to repair itself. Chronic inflammatory response, however, where inflammation continues beyond its intended duration, has been shown by research to contribute to ongoing health conditions such as cardiovascular disorders, type-2 diabetes, some types of arthritis, and more. (5, 6)

So how can tart cherry potentially help?

Here are some examples provided by scientific research:

• Tart cherry juice may help to decrease inflammation in chronic conditions, though more research is needed. (7)

• A 2023 meta-analysis found that regular consumption of cherry juice could manage inflammation throughout the body, though it did depend on finding the right dose. (8)

• A four-week study concluded that overweight or obese people who took 320mg of anthocyanins daily showed significantly lower markers of inflammation, leaving the authors to conclude that anthocyanin supplementation "may be effective in countering overweight/obesity-induced inflammation." (9)

• A 2019 study showed that the antioxidants in tart cherry juice may help reduce inflammation and joint pain from osteoarthritis. Participants who drank two cups of cherry juice a day for four months experienced less knee pain as a result. The authors concluded that drinking the juice daily helped to improve pain relief, quality of life, mobility, and "selective markers of cartilage health." (10)
  

Muscle Recovery and Athletic Performance

As an extension of its aforementioned antioxidant qualities, tart cherry fruit has also been shown to help reduce muscle inflammation and soreness after exercise, particularly in combination with other recovery strategies, protecting against muscle damage and aiding faster recovery. (11, 12, 13, 14)

Sleep Support

A third of adults in America struggle with insomnia, with a tenth describing it as chronic. We're crying out for effective natural sleep aids, and the good news is that tart cherries could potentially be one of them. (15)

Cherries contains natural melatonin, the "sleep hormone" that lets our bodies know when it's time to wind down for bed. Melatonin is crucial to our sleep/wake cycle, helping us to sleep at night and be awake and alert during the day.

Unfortunately, our modern lifestyle—including artificial light and blue light from televisions, computers, tablets, and phones—often interrupts this. An extra source to improve sleep—and a natural one at that—is always welcome.

Tart cherries also contain an amino acid called tryptophan that the body can convert into serotonin (the “feel good” hormone) and more melatonin. Because of certain enzymes, they allow that tryptophan to stay in the body for longer, working harder. (16)

Tart cherries contain up to 50 times more melatonin than sweet cherries, (17) and Montmorency cherries offer up to six times more melatonin than other forms of tart cherry. (18)

Let's look at some sleep facts about tart cherries, as proven by scientific trials.

Tart cherries may help your sleep by:

• Increasing the time spent asleep while in bed, known as sleep efficiency.

• Enhancing overall sleep time across all age groups. (19)

• Potentially helping to manage disturbed sleep. (20)

One study focused on people over 50 struggling with insomnia showed that tart cherry improved sleep time by up to 84 minutes. Researchers noted that tart cherry “may be partially responsible for improvement in insomnia.” (21)

Heart Health

We already know that fruits and vegetables are good for us, but it seems tart cherries (or Prunus cerasus) may be beneficial for our heart health. Once again, that's due to their inflammation-modulating and antioxidant properties.

Tart cherries have been shown to encourage cardiovascular wellness (22) by:

Lowering Cholesterol Levels

• One 12-week study of older adults taking tart cherry juice demonstrated that it helped to reduce low-density lipoprotein (LDL) cholesterol, also known as “bad” cholesterol. (23) Lowering LDL cholesterol helps to reduce cardiovascular disease risk. (24)

• Other studies have shown that anthocyanins may help to increase high-density lipoprotein (HDL) cholesterol (or “good” cholesterol) while lowering LDL cholesterol. (25, 26, 27)

Decreasing Blood Pressure 

The high levels of potassium in tart cherry juice concentrate and supplements may help to lower blood pressure (BP), which can help to reduce the risk of cardiovascular disease. (28, 29)

The science:

• A 12-week study of older people over 70 with mild-to-moderate dementia showed that drinking 200ml of cherry juice a day reduced both their systolic and diastolic BP. (30)

• Another study of adults drinking 300ml of anthocyanin-rich juice showed a significant drop in BP. This occurred in all age groups but was more obvious in older adults. (31)

• A 2018 systematic review of tart cherry research on BP concluded that it has the potential to reduce both systolic and diastolic BP in certain subjects, but perhaps not in others. This may be related to their health status to begin with. Dosage and time between doses may also play a role in the results. (32)

More research into all of these areas is welcome.

Limited Research for Other Health Benefits

There is also limited research for the following:

• Taking tart cherry may support memory in those experiencing age-related cognitive decline. A 12-week study suggested that people with mild-to-moderate dementia saw an improvement in short- and long-term memory as well as verbal fluency after taking cherry juice. (33)

• The anthocyanin content may help to protect the immune system. (34)

• Several studies have suggested that tart cherries may help to reduce uric acid, implicated in gout symptoms. However, research is at the very early stages, and more studies are needed. The Arthritis Foundation stops short of recommending a specific cherry regimen but does state that a handful of cherries a day "can't hurt." (35, 36)

Who Should and Shouldn’t Take Tart Cherry Supplements?

Most people won't have a problem taking tart cherry supplements. Indeed, taking cherry in supplement form is easier and more convenient than trying to eat enough cherries to compete with the dosage (around 100!) commonly used in clinical trials.

Likewise, cherry supplements help to avoid the extra sugar often found in cherry juices.

However, tart cherry may interact with certain medications, such as blood thinners, and may cause problems for people with certain medical conditions, such as kidney disease or gout. (37)

Please consult with a healthcare professional if you have a medical condition or are taking any medication.

If you have an allergy, you should also avoid them.
