The Power Packed Into a Small, Sour Fruit
Unlike the sweet cherries you might snack on, tart cherries (specifically the Montmorency variety) are known for their sharp flavour and, more importantly, their dense nutritional profile. They are loaded with vitamins and minerals, but their real claim
to fame in the fitness world comes from their high concentration of phytochemicals, particularly anthocyanins. These are powerful antioxidant compounds that give the cherries their bright red colour. It's these anthocyanins that are believed to be responsible for the juice's potent anti-inflammatory and antioxidant effects, which are central to its benefits for exercise.
Tackling Post-Workout Muscle Soreness
Delayed Onset Muscle Soreness (DOMS) is the pain and stiffness felt in muscles several hours to days after unaccustomed or strenuous exercise. This soreness is a result of micro-tears in the muscle fibres and the subsequent inflammation. The anthocyanins in tart cherry juice appear to help by reducing this inflammation and combating oxidative stress caused by intense activity. Multiple studies on athletes, including marathon runners and weightlifters, have shown promising results. Research suggests that regular consumption of tart cherry juice can lead to a noticeable reduction in muscle pain and a faster recovery of strength after exercise. It essentially helps your body manage the inflammation process more efficiently, allowing you to get back to your training with less discomfort.
An Unexpected Secret to Better Sleep
Quality recovery isn't just about managing sore muscles; it's also about getting enough restorative sleep. This is where tart cherry juice offers a compelling two-for-one benefit. Tart cherries are one of the few natural food sources of melatonin, the hormone that regulates our sleep-wake cycles. While the amount of melatonin is modest, it's complemented by another compound: tryptophan. Tryptophan is an amino acid that the body uses to produce its own melatonin. Some research suggests tart cherry compounds may even help the body preserve its available tryptophan, further supporting this process. Studies have shown that drinking tart cherry juice can increase sleep time and improve sleep quality, particularly for those with mild insomnia. For an athlete, this means more time in the deep sleep stages where muscle repair and growth hormone release are at their peak.
How to Use It in Your Fitness Routine
To get the benefits, consistency is key. Most studies use a protocol of drinking it daily, not just on workout days. The common recommendation is to have about 240ml of juice or a 30ml shot of concentrate, often taken twice a day—once in the morning and once in the evening. For best results in reducing muscle soreness, many athletes start drinking it several days before a big event or an intense training block and continue for a couple of days after. When choosing a product, look for 100% tart cherry juice without added sugars, as many commercial juices can be high in sweeteners, which can add unnecessary calories and counteract some of the health benefits. The unsweetened concentrate is often a more cost-effective and lower-sugar option.
Are There Any Downsides?
For most people, tart cherry juice is safe. However, it's worth being aware of a few things. As mentioned, be mindful of added sugars. The juice also contains sorbitol, a type of sugar alcohol that can cause digestive discomfort, like gas or diarrhoea, in some individuals, especially when consumed in large quantities. Furthermore, due to its plant compounds, it could potentially interact with certain medications, such as blood thinners. People with existing health conditions, especially related to the kidneys, should consult a doctor before making it a regular part of their diet.
