What is Chlorophyll?

In plain words

Chlorophyll is the green pigment that helps plants capture sunlight; many “liquid chlorophyll” products contain a modified form called chlorophyllin. Digestion changes chlorophyll into related substances, and only some of these are absorbed. Researchers study these substances for effects on body odors and the absorption of certain harmful chemicals in food. Evidence for broad “detox” or anti-aging benefits is limited, and supplements can cause stomach upset or green stools.

Technical definition

Chlorophyll is a class of magnesium-containing chlorin pigments that absorb light for photosynthesis in plants, algae, and cyanobacteria; chlorophyllin, commonly marketed as “liquid chlorophyll,” is a chemically modified, water-soluble derivative often containing copper instead of magnesium. Dietary chlorophyll undergoes digestive conversion into derivatives such as pheophytins, and neither chlorophyll nor chlorophyllin has an established human therapeutic receptor target; research includes their potential to bind certain dietary carcinogens and reduce their absorption. Regulatory status depends on formulation and intended use: products are sold as dietary supplements, while certain chlorophyllin formulations have specific color-additive or over-the-counter internal-deodorant uses in the United States.
