Research published in the journal Hypertension analyzed the results of nine other probiotic studies (over 540 adult participants). The researchers found that, compared to participants who did not consume probiotics, individuals who consumed probiotics (including the ones found in yogurt) on a regular basis lowered their systolic blood pressure on average by 3.56 mm Hg (mercury) and diastolic blood pressure by 2.38 mm Hg. The results were only found in the consumption of probiotics that had at least 109 colony-forming units (commonly called CFU). Any probiotics with fewer colonies were not found to be beneficial in lowering blood pressure.
