The main active ingredient in our hum™ sugar-free gum is our 95% pure Stevita stevioside. Other natural ingredients are added to give texture, such as xylitol and beeswax. Studies have shown that the stevioside and xylitol prevent the formation of dental cavities in rats, therefore the regular use of hum™ could promote the maintenance of healthy teeth. It contains no petroleum products or artificial ingredients. Available in Mint or Cinnamon Flavor.
