Bifidobacterium-based Probiotics(The University of Hong Kong)

The primary objective of this study is to investigate if a Bifidobacterium-based probiotic intervention would reduce clinic systolic BP in untreated middle-aged Chinese men and women with hypertension according to ACC/AHA guidelines (SBP ≥130 mm Hg) after 12 weeks of treatment. The investigators anticipate that this feasibility study will provide rationale to conduct a larger randomized clinical trial and preliminary data to estimate the power/ sample size of a larger RCT.
