Regular intake of probiotics, such as those found in certain yogurts or supplements, may have the potential to lower high blood pressure. A study involving 543 adults with either normal or elevated blood pressure found that probiotic consumption resulted in an average decrease of systolic blood pressure of 3.6 mmHg and a 2.4 mmHg decrease in diastolic blood pressure. The authors of the study also note that probiotics with multiple types of bacteria lowered blood pressure more than those with a single type of bacteria.
