Tart Cherry, also known as sinyang-aengdu or Prunus cerasus, is a variety of cherry that is notable for its tart and sour taste, distinguishing it from the more commonly found sweet cherries. Tart Cherries have a vibrant and intense red color compared to the regular cherries typically seen in the market. Recently, Tart Cherries have garnered significant attention from individuals worldwide who struggle with insomnia, as they have been discovered to promote restful sleep.

Abundant Melatonin Content in Tart Cherry

Tart Cherries are known for their high melatonin content. Melatonin, a hormone that regulates the body's biorhythm and offers anti-aging benefits, plays a crucial role in improving sleep quality. Sleep aid products in the United States typically contain melatonin ranging from 2 mg to 10 mg. A study published in the Journal of the Korean Society of Food Science and Nutrition in 2002 revealed that Tart Cherries contain approximately 7 mg of melatonin per 1 kg, providing a significant sleep-enhancing effect when consumed. Another clinical trial conducted by the European Journal of Nutrition showed that participants who consumed 30 ml of Tart Cherry juice daily for a week experienced an increase in melatonin levels and a corresponding 5-6% improvement in sleep efficiency. The sleep-promoting effects of Tart Cherries have been extensively supported by researchers worldwide in various studies.

Furthermore, Tart Cherries are not only rich in sleep-promoting properties but also contain abundant anti-inflammatory compounds. These compounds contribute to alleviating chronic inflammation and are known for their high levels of antioxidants, which help eliminate reactive oxygen species and aid in preventing obesity. It's no wonder Tart Cherries are often referred to as "red diamonds."

How should it be consumed? 

Using natural foods like Tart Cherries for sleep rhythm improvement can be a great method for individuals struggling with sleep disorders. Since Tart Cherries have a soft texture and a strong sour taste, they are commonly consumed in the form of juice, concentrate, or dried products rather than as fresh fruit.

However, buying Tart Cherries and juicing them regularly can be inconvenient and difficult. Moreover, commercially available concentrated juices often go through a prolonged heating process to extract the concentrate from diluted Tart Cherries, leading to the loss of nutrients due to heat. Recently, sleep aid beverages have emerged that not only contain a rich amount of melatonin found in Tart Cherries but are also made exclusively from natural ingredients. These sleep beverages are becoming a promising alternative to traditional sleep aids for individuals struggling with insomnia.

The sleep beverage Sleeping Bottle is enriched not only with Tart Cherries but also with 10 natural ingredients, including Ecklonia extract and Hawthorn Berry, known to promote better sleep. Unlike prescription sleep medication, Sleeping Bottle is made from natural ingredients, alleviating concerns about potential side effects and making it suitable for long-term consumption by people of all ages. For those considering Tart Cherry intake for improved sleep, choosing convenient sleep beverages like Sleeping Bottle can be a beneficial alternative.
