Tart Cherry Supplementation & Gut Microbiome and Inflammation

Completed · Not applicable · Has a placebo group

Conditions studied: Inflammation, Glucose Regulation, Sleep

In brief

There has been a rapid increase in researching the use of tart cherry supplements in the past 5 years, particularly for inflammatory conditions. Many formulations of cherry supplements exist, however there has been no comparison between these different types. This is particularly important in the realm of inflammation research because sugar is known to increase the inflammatory response. The pill form of cherry supplementation has no added sugar and is naturally low in sugar (\< 1g) while the juice form is higher from added sugar. Recent work indicates tart cherry consumption can change gut microbiota, which may modify inflammation. The purpose of this study is to look at the effects of taking a cherry supplement, either in capsule or juice form, on the gut microbiome, inflammation, and health-related variables such as blood pressure, glucose regulation and sleep quality.
