Xylitol Chewing Gum
Gum makes a great choice as a xylitol source. It's convenient to use and it creates an exposure that lasts for an extended period of time. As a bonus, the act of chewing it provides an anti-cavity effect on its own.
More studies have evaluated the use of gum than any other type of xylitol product.
Look for brands that offer 1 or more grams per piece.
The best gums usually list xylitol first in their ingredient list. (More about how to read labels.)
