The Power Inside the Cherry
The secret to tart cherry juice's benefits lies in its rich nutritional profile. Specifically, Montmorency cherries—the variety most commonly used for juice—are packed with powerful plant compounds called anthocyanins. These are the antioxidants that
give the fruit its deep, ruby-red colour. Anthocyanins are believed to have potent anti-inflammatory and antioxidant properties, which are central to the claims about muscle recovery. Additionally, tart cherries are one of the few natural food sources of melatonin, the hormone that regulates our sleep-wake cycle. They also contain tryptophan, an amino acid that the body uses to produce its own melatonin.
Soothing Sore Muscles After Exercise
Delayed Onset Muscle Soreness (DOMS) is the familiar ache that sets in a day or two after an intense or unfamiliar workout. This soreness is a result of microscopic muscle damage and the subsequent inflammation. Research suggests that the anthocyanins in tart cherry juice can help manage this process. Studies have shown that athletes who supplement with tart cherry juice before and after strenuous events experience less muscle pain and faster recovery of strength. For instance, one study on marathon runners found that those who drank the juice had significantly reduced inflammation and recovered their strength more quickly compared to a placebo group. The antioxidants appear to help protect muscle cells from damage and modulate the body's inflammatory response, acting as a natural alternative to aid recovery.
A Natural Nudge Towards Restful Sleep
The connection between tart cherry juice and sleep is primarily linked to its melatonin content. While the amount of melatonin is lower than what you'd find in a typical supplement, studies suggest it can still have a positive effect. Research, although often conducted with small groups, has shown promising results. One 2018 study involving older adults with insomnia found that drinking tart cherry juice twice a day for two weeks increased their average sleep time by 84 minutes. Another study noted that participants who drank the juice for seven days not only had higher melatonin levels but also experienced longer total sleep time and better sleep efficiency. The combination of naturally occurring melatonin and tryptophan appears to gently support the body's own sleep cycle.
How to Use It: Dosage and Timing
For those looking to try tart cherry juice, consistency is key. Most studies involve a loading phase. A common recommendation for athletes is to drink 8 to 12 ounces (about 240-355 ml) of juice or 1 ounce (30 ml) of a concentrate, twice a day. This is often done for four to five days before a big event and continued for two to three days after to maximise recovery benefits. For sleep, drinking a serving about 30 minutes to two hours before bed is a common suggestion. It is crucial to choose 100% tart cherry juice with no added sugars, as extra sweeteners can negatively impact blood sugar levels and potentially interfere with sleep.
Are There Any Downsides?
For most healthy adults, tart cherry juice is considered safe. However, there are a few things to keep in mind. The juice contains sorbitol, a natural sugar alcohol that can cause digestive discomfort like gas or bloating in some people, especially in larger quantities. As mentioned, it's also important to be mindful of the natural sugar content, particularly for individuals with diabetes. While rare, some people who are sensitive to melatonin may feel groggy the next day. Additionally, because of certain compounds in cherries, it's wise to speak with a doctor before making it a daily habit if you take medications like blood thinners.
