Chlorophyll is a green pigment naturally produced by plants and algae and gives them their characteristic green color. Chlorophyll is critical for photosynthesis, the process by which sunlight is converted into chemical energy. Chlorophyll can function as a free radical neutralizer, may help to support the body's detoxification processes and has been traditionally used as an internal deodorizer. This water-soluble extract is in the form of sodium copper chlorophyllin.
