Honor Whiteman

Probiotics 'may help reduce high blood pressure and maintain healthy blood pressure'

FAB RESEARCH COMMENT:

Find the underpinning research here: Khalesi et al 2014 - Effect of Probiotics on Blood Pressure
Research led by Jing Sun, PhD, of the Griffith Health Institute and School of Medicine at Griffith University in Australia, suggests that consuming probiotics from food sources and dietary supplements may improve blood pressure.

To reach their findings, Sun and his team analyzed nine high-quality studies that assessed the probiotic consumption of 543 adults who had either normal or high blood pressure.

They found that on average, participants who had consumed probiotics daily for 8 weeks or more had a 3.5 mm Hg lower systolic blood pressure (pressure in the arteries when the heart beats) and a 2.38 mm Hg lower diastolic blood pressure (pressure in the arteries between heartbeats), compared with those who did not consume probiotics.

Such effects were strongest among participants with high blood pressure - defined as 130/85 mm Hg or more - and greater benefits were found from consumption of probiotic products that contained multiple bacteria.
