The Claim
Chlorhexidine mouthwash reduces salivary nitrite by over 80% and plasma nitrite by more than 70% compared to water by nearly eliminating the conversion of dietary nitrate to nitrite, and it is the most potent disruptor of the oral microbiome-dependent nitric oxide pathway among tested formulations.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Using chlorhexidine mouthwash reduces salivary nitrite by more than 80% and plasma nitrite by more than 70% compared to water, by blocking the conversion of dietary nitrate to nitrite, and it is the strongest known disruptor of this pathway among tested mouthwashes.
See the scientific wording
Chlorhexidine mouthwash nearly eliminates the conversion of dietary nitrate to nitrite, reducing salivary nitrite by over 80% and plasma nitrite by more than 70% compared to water, demonstrating it is the most potent disruptor of the oral microbiome-dependent nitric oxide pathway among tested formulations.
Chlorhexidine kills bacteria on the tongue that convert dietary nitrate into nitrite. Without these bacteria, nitrite does not form in the mouth, so it cannot enter the bloodstream. Lower nitrite in the blood means less nitric oxide is made, which prevents blood vessels from relaxing and raises blood pressure.
What the research says
1 studyThis study found that using chlorhexidine mouthwash after drinking beetroot juice almost stops the body from turning the juice’s natural compounds into nitrite, which helps lower blood pressure. Among all mouthwashes tested, chlorhexidine was the most effective at blocking this helpful process.
