Tart Cherry Juice Drink Touted as Sleep Aid The "Sleepy Girl Mocktail" has gained popularity on TikTok, but experts are skeptical about its effectiveness. The mocktail combines magnesium, seltzer, and tart cherry juice, with claims of improving sleep. However, research on tart cherry juice as a sleep aid is limited, and the amount of melatonin it contains is relatively low. Similarly, the impact of magnesium on sleep is not conclusively proven. While the mocktail may offer a placebo effect, some believe its ritualistic preparation could contribute to better sleep. Despite skepticism from experts, the mocktail may appeal to those seeking an alcohol-free alternative for better rest.
