As a supplement

Talk to your doctor or pharmacist.

Roll Call does not check drug interactions or assess personal safety.

The green pigment that plants use to capture light for photosynthesis, extracted and sometimes chemically stabilized (as chlorophyllin) for use in supplements.

Why it’s used

Taken by some for general wellness claims, including as an internal deodorizer for body or breath odor, or for antioxidant support.

What the evidence says

Human evidence is limited and mostly old or small in scale. There is no NIH Office of Dietary Supplements fact sheet on chlorophyll, and claims around detoxification, odor control, or antioxidant benefit in humans have not been established through robust clinical trials.

This says what this database holds under these terms. It is not a finding that no research exists.

Context

Where studied, research has more often examined chlorophyllin (a semi-synthetic derivative) rather than natural chlorophyll, and doses and outcomes vary widely across the small existing literature.

Insufficient dataToo little has been studied to say either way.
