Chlorophyll [Intestinal] is the green pigment in plants that harnesses the sun�s energy in photosynthesis. Chlorophyll performs metabolic functions in plants such as respiration and growth. Interestingly, the chlorophyll molecule is chemically similar to human blood, except that its central atom is magnesium, whereas that of human blood is iron. Liquid Chlorophyll may help improve immune response and deodorize the body. The alfalfa plant, from which Nature�s Sunshine�s chlorophyll comes, is an excellent source of chlorophyll. Nature�s Sunshine offers chlorophyll in both liquid and capsules for varying needs.
