Bad breath can have many causes, from poor dental hygiene to the natural production of digestive gases. Brushing and flossing takes care of the first kind but not the second. That's why some bad breath odors like garlic are so hard to eliminate with mouthwashes, brushing or mints. Mint Asure from Rainbow Light was formulated on this principle, to freshen breath from the inside out. Unlike mouthwashes and mints that only add minty-ness to bad breath odor, Mint Asure attacks the root cause of the worst kinds of bad breath by using a mint-coated parsley oil capsule that your hold in your mouth before swallowing. Mint Asure immediately freshens your mouth before it goes to work neutralizing stomach gases - the source of the most difficult-to-eliminate bad breath odor.
