Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dysbiosis of gut microbiota has been reported to be involved in the development and progression of hypertension in both humans and animal models. Probiotics have been reported to have ameliorative effects in murine models. However, whether probiotics could help alleviate hypertension in adults remain obscure.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Probiotics are live microorganisms that have been associated with multiple health benefits. However, its protective role in adults has long been controversial. This study aims to examine the effect of 12-week probiotics supplementation on the prevention of hypertension in Chinese adults. By understanding the mechanisms by which probiotics exert this beneficial effects, we can better control the rising prevalence of hypertension, which is a major risk factor for cardiovascular diseases.
