Xylitol: Main Image

Xylitol is the alcohol form of xylose, which is used as a sweetener in chewing gums and other dietetic products. Xylitol has less effect on blood sugar or insulin levels compared with sucrose,1 so it may be a useful sugar substitute for diabetics.2 In addition, xylitol inhibits the growth of several types of bacteria, including those that cause tooth decay and ear infections.3, 4, 5, 6

  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
