Although there was no difference in timing of the melatonin circardian rhythm, there was a trend to a higher mesor and amplitude. There were significant increases in time in bed, total sleep time and sleep efficiency total (P < 0.05) with cherry juice supplementation. Total melatonin content was significantly elevated (P < 0.05) in the cherry juice group, whilst no differences were shown between baseline and placebo trials. Tart cherry juice is available as a traditional juice, although the medicinal value is said to be less than the concentrated form. Though in different forms, the concentrate and the capsules are still commonly referred to as juice.
#TART CHERRY PILLS OR JUICE TRIAL#
Trial differences were determined using a repeated measures ANOVA. Choosing the best juice largely depends on what you plant to use it for, and so the form it comes in will be key. In addition, total urinary melatonin content was determined over the sampled period. If you’re looking for a natural way to treat your gout, tart cherry extract may be worth a try. You can take it in capsule form or mix it into water or juice.
Sequential urine samples over 48 h were collected and urinary 6-sulfatoxymelatonin (major metabolite of melatonin) determined cosinor analysis was used to determine melatonin circadian rhythm (mesor, acrophase and amplitude). However, most experts recommend taking 500-1000 mg of tart cherry extract per day.
Measures of sleep quality recorded by actigraphy and subjective sleep questionnaires were completed. In a randomised, double-blind, placebo-controlled, crossover design, 20 volunteers consumed either a placebo or tart cherry juice concentrate for 7 days. It is possible that unknown interactions exist. The aim of our investigation was to ascertain whether ingestion of a tart cherry juice concentrate would increase the urinary melatonin levels in healthy adults and improve sleep quality. As of the last update, we found no reported interactions between this supplement and medicines. Tart Montmorency cherries have been reported to contain high levels of phytochemicals including melatonin, a molecule critical in regulating the sleep-wake cycle in humans.
