The Zolli line is an all-natural, gluten-free, dairy-free, vegan and non-GMO candy, and certified sugar-free by Sugarwise. It contains xylitol and erythritol to not only provide guilt-free sweetness, but to improve oral health. By helping raise the pH (a scale used to measure acidity and alkalinity) in the mouth, Zolli Candy neutralizes acid and helps reduce the risk of tooth decay, dental caries and future development of cavities.
