In its natural form, chlorophyll is a chemical that gives green plants their color. In addition to leafy green plants, you'll also find chlorophyll in some supplements.1
Chlorophyll is sold as a tablet, capsule, or liquid with a dropper for dispensing the green solution. You may see fans of the liquid chlorophyll supplement swirl it into water.
Some evidence suggests that liquid chlorophyll may help with weight loss, prevent some cancers, and treat certain skin concerns. Although, as of 2023, researchers have not fully studied those possible benefits. More research is needed to figure out the efficacy and safety of liquid chlorophyll.
