Method: The aim of this human randomized, double-blind parallel arm pilot study was to explore the impact of aqueous Wild Thyme extract, a food supplement, in a healthy but overweight study collective (N = 40). In detail, the impact on digestion, gastrointestinal symptoms, gut microbiome, and quality of life by employing an essential oil-free WThE preparation or a matching placebo was investigated. Results: The study results indicate that WThE has the potential to improve gastrointestinal symptoms and increase stool frequency, thus an improved quality of life was observed. The stool microbiome of study collective was characterized by a high Firmicutes to Bacteroidetes ratio. A decrease in the mean Firmicutes/Bacteroidetes ratio was seen in WThE group. Conclusion: The data support the potential applications of WThE as a food supplement with benefits on gut health.展开更多
