Some benefits of taking chlorophyll as a dietary supplement include reducing bad breath, minimizing constipation and speeding up the rate of healing, according to WebMD. There is little research to support these claims and prove the actual effectiveness of chlorophyll in humans.
As a dietary supplement, chlorophyll is available in liquid form, but people can obtain it through the consumption of green vegetables such as green beans, parsley and spinach, notes WebMD. People typically take chlorophyll by mouth, but they can inject it intravenously as well. Chlorophyll obtained through an IV alleviates various levels of pain and treats symptoms of chronic pancreatitis.
