Chlorophyll and Breath: What the Research Shows

Chlorophyll has been studied as an internal deodorizer since the 1950s. Westcott (1950) found chlorophyllin reduced body odors in hospitalized patients. The mechanism involves binding to odor-causing compounds and neutralizing them.

The honest gaps: Most studies used 100-200mg. NightSip contains 25mg, intentionally conservative for safe daily use. The studies addressed body odor, not specifically oral malodor.

We list this openly on our [dosage transparency table](/science#dosage). Even at a modest dose, chlorophyll is well-tolerated and has a plausible mechanism. Combined with zinc and aloe vera, it fills a specific role. It is not carrying the product alone.
