Women’s mouths have bacteria that turn nitrate into something else more efficiently than men’s, whether or not they’ve taken nitrate supplements—and this isn’t because their mouth bacteria are different kinds.
Claim Language
Language Strength
definitive
Uses definitive language (causes, prevents, cures)
The verb 'demonstrate' is used to assert a clear, observable difference between groups, implying certainty in the outcome rather than suggesting possibility or association. The phrase 'independent of differences' further reinforces a definitive causal separation from confounding variables.

Sex differences in the nitrate‐nitrite‐NO• pathway: Role of oral nitrate‐reducing bacteria
The study found that women’s mouths convert more nitrate to nitrite than men’s, both before and after taking nitrate supplements, and this isn’t because they have different bacteria — it’s just how their bodies work differently.
