What Makes Tart Cherry Juice Special?
Tart cherry juice, most commonly made from the Montmorency cherry, is distinct from the sweet cherries you might snack on. These sour cherries are packed with a high concentration of beneficial plant compounds, most notably anthocyanins. Anthocyanins
are powerful antioxidants that give fruits and vegetables their deep red, purple, and blue colours. It is these compounds, along with other vitamins and minerals, that are believed to be responsible for the juice's health-promoting properties. Beyond just juice, tart cherries are also available in concentrate, powders, and capsules, offering different ways to get their benefits.
Soothing Sore Muscles After Exercise
One of the most well-researched benefits of tart cherry juice is its role in aiding exercise recovery. Strenuous physical activity causes micro-tears in muscle fibres, leading to inflammation, oxidative stress, and the familiar feeling of delayed onset muscle soreness (DOMS). The anthocyanins in tart cherries act as potent anti-inflammatory agents, helping to manage this response. Several studies have shown that athletes who consume tart cherry juice before and after intense exercise experience less muscle pain and a faster recovery of strength. For example, one meta-analysis noted that supplementation significantly improved muscle strength recovery post-exercise. Another study found that runners who drank the juice for seven days leading up to a marathon reported three times less soreness than a placebo group. By reducing inflammation and oxidative damage, the juice helps protect muscle tissue and preserve function, allowing for a quicker return to training.
A Natural Way to Enhance Your Sleep
If you struggle with sleep, tart cherry juice might offer some help. Tart cherries are one of the few natural food sources of melatonin, the hormone that regulates our sleep-wake cycle. Montmorency cherries, in particular, contain significantly higher levels of melatonin compared to other varieties. But the effect isn't just from the melatonin content alone. Tart cherries also contain tryptophan, an amino acid that the body uses to create more melatonin. Furthermore, certain compounds in the juice may inhibit an enzyme that degrades tryptophan, allowing it to remain active in the body for longer. This dual-action mechanism—providing melatonin directly while also supporting the body's own production—is why research suggests it can increase total sleep time and improve sleep quality, especially for those with insomnia.
How to Add It to Your Routine
For the best results, consistency is key. Research protocols often involve drinking the juice for several days. For muscle recovery, many studies use a protocol of about 240ml of juice (or 30ml of concentrate) twice daily for a few days before and after a strenuous event. For sleep benefits, a similar amount taken once or twice a day, with one serving about an hour before bed, is often recommended. When buying juice, look for 100% unsweetened tart cherry juice to avoid added sugars, which can negate some of the health benefits. If you opt for a concentrate, a common serving is around 30ml mixed with water. Capsules and powders are also effective, convenient, and low-calorie alternatives.
Are There Any Potential Downsides?
While generally safe for most people, tart cherry juice does have a few potential side effects. The juice contains sorbitol, a type of sugar alcohol that can cause digestive discomfort, gas, or diarrhoea in some individuals. Due to its natural sugar content, those with diabetes should monitor their blood sugar levels, especially with sweetened varieties. Additionally, it's wise to speak with a doctor before making it a regular part of your diet if you are pregnant, have kidney disease, or are taking certain medications like blood thinners, as interactions are possible.
