How mouth bacteria affect blood pressure
Altered Oral Nitrate Reduction and Bacterial Profiles in Hypertensive Women Predict Blood Pressure Lowering Following Acute Dietary Nitrate Supplementation
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
Mouth bacteria help turn dietary nitrate into substances that lower blood pressure. This study looked at how these bacteria work in women with and without high blood pressure.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Bacteria in the mouth help regulate blood pressure by converting nitrate to nitrite, which is part of the body's natural blood pressure control system.
Women with high blood pressure have much lower levels of nitrite in their saliva than women with normal blood pressure.
Women with high blood pressure have much less of the bacteria Veillonella in their mouths compared to women with normal blood pressure.
Whether a woman is pregnant or not doesn't seem to affect how well her mouth bacteria can convert nitrate to nitrite.
Women with high blood pressure tend to have slightly lower mouth bacteria activity for converting nitrate to nitrite compared to women with normal blood pressure, though this difference isn't quite statistically significant.
