Probiotics may lower blood pressure

A systemic review of nine clinical studies examining blood pressure and probiotic consumption in 543 adults with normal and elevated blood pressure has concluded that probiotic supplementation was associated with reduced blood pressure.

The probiotics need to be taken for at least two months.

Probiotics may help lower blood pressure by having other positive effects on health, including improving total cholesterol and low-density lipoprotein, or LDL, cholesterol; reducing blood glucose and insulin resistance; and by helping to regulate the hormone system that regulates blood pressure and fluid balance.

The effect on blood pressure is modest, however, probiotics has many other benefits including better intestinal health.
