Now Foods XyliWhite toothpaste is fluoride free. Now Foods Xyliwhite toothpaste is completely safe for users of every age. Now Foods XyliWhite Toothpaste is a remarkable new toothpaste gel from NOW Foods that uses Xylitol, a natural sugar alcohol that looks and tastes similar to conventional sugar with one major exception - it has 40% fewer calories! Unlike many of the chemicals found in other fluoride based, whitening toothpastes, xylitol is a natural, well-tolerated substance commonly found in fruits, berries and other natural sources. In fact, the human body even manufactures its own supply - up to 15 grams, everyday. Xyliwhite is an all-natural “refreshmint” toothpaste made from select materials and guaranteed to be of superior quality. NOW's decision to introduce new Xyliwhite toothpaste was not made overnight. Rather, it was the result of intense worldwide research and official endorsements from 6 international dental associations. Though it was discovered in the 1800's, xylitol research has surged over the last 50 years. Some of the most notable studies (including those conducted at Finland's Turku University) have tested xylitol's ability to fight cavities, plaque, gingivitis, dry mouth and bad breath. Others have tested its ability to help neutralize plaque acids, assist in the re-mineralization of tooth enamel and attack the bacteria that can cause tooth decay. At the end of the day, this research ultimately suggests that xylitol may help promote a smile that is whiter, brighter and far more healthy.
