Yogurt Could Lower Your Blood Pressure: New Study

We all have heard that eating probiotics – “good” bacteria – keeps us healthy by aiding digestion, intestinal function and protecting against harmful bacteria. But the new research published in the American Heart Association journal Hypertension suggests that eating probiotics could help lower blood pressure as well.

Probiotics, the naturally present live microorganisms in our gut, are also present in live-cultured yogurt, some fermented vegetables and aged cheeses.

Based on the past research that probiotics are good for our health, many supplement manufacturers have developed products containing different and multiple strains of probiotics.

In a new research at Griffith Health Institute and School of Medicine at Griffith University in Australia, Jing Sun, PhD, and her team analyzed nine high-quality studies that assessed the probiotic consumption of 543 adults who had either normal or high blood pressure. Based on his analysis, Sun suggests that consuming probiotics from food sources and dietary supplements may improve blood pressure. Sun and his team found that:

  1. Probiotic consumption lowered systolic blood pressure (the top number, which is also the higher of the two numbers, measures the pressure in the arteries when the heart beats — when the heart muscle contracts) by an average 3.56 millimeters of mercury (mm Hg) and diastolic blood pressure (the bottom number, which is also the lower of the two numbers, measures the pressure in the arteries between heartbeats — when the heart muscle is resting between beats and refilling with blood) by an average 2.38 mm Hg, compared to adults who did not consume probiotics.
  2. The positive effects from probiotics on diastolic blood pressure were greatest in people whose blood pressure was equal to or greater than 130/85, which is considered elevated.
  3. Consuming probiotics for less than eight weeks didn’t lower systolic or diastolic blood pressure.
  4. Probiotic consumption with a daily bacteria volume of 109-10 12 colony-forming units (CFU) may improve blood pressure. Consumption with less than 109 CFU didn’t lower blood pressure. CFU is the amount of bacteria or the dose of probiotics in a product.
  5. Probiotics with multiple bacteria lowered blood pressure more than those with a single bacterium.


This chart reflects blood pressure categories defined by the American Heart Association.

Blood Pressure
mm Hg (upper #)
mm Hg (lower #)
Normal less than 120 and less than 80
Prehypertension 120139 or 8089
High Blood Pressure
(Hypertension) Stage 1
140159 or 9099
High Blood Pressure
(Hypertension) Stage 2
160 or higher or 100 or higher
Hypertensive Crisis
(Emergency care needed)
Higher than 180 or Higher than 110

Commenting on the team’s findings, Sun says:

“The small collection of studies we looked at suggest regular consumption of probiotics can be part of a healthy lifestyle to help reduce high blood pressure, as well as maintain healthy blood pressure levels.”
