Xylitol

Alternative Medicine
The following information is specific for alternative and complementary medicine. For additional evidence-based information on diseases, conditions, symptoms, diagnosis, treatment and wellness issues, continue searching the Healthwise Knowledgebase.

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

Where is it found?

Xylitol occurs naturally in straw, corncobs, fruit, vegetables, cereals, mushrooms, and some seaweeds. For use in food manufacturing, xylitol is extracted from birch wood chips. Xylitol may be found in many foods labeled as "sugar-free," including hard candies, cookies, chewing gums, soft drinks, and throat lozenges.

Health Concerns

Xylitol has been used in connection with the following conditions (refer to the individual health concern for complete information):

Rating	Health Concerns
	Ear infections Tooth decay
Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. An herb is primarily supported by traditional use, or the herb or supplement has little scientific support and/or minimal health benefit.

Deficiency Symptoms

Who is likely to be deficient?

Xylitol is not an essential nutrient; therefore, no deficiencies are possible.

Dosage

How much is usually taken?

For prevention of dental caries (cavities), 7 to 20 grams per day are given, divided into several doses in candies or chewing gum. For prevention of ear infections, 1.7 to 2.0 grams are given fives times per day in gum, lozenges, or syrup.

Side Effects

Are there any side effects or interactions?

Xylitol is recognized as a safe food additive by the U.S. government.⁷ Large amounts (30 to 40 grams) taken all at once can produce diarrhea and intestinal gas.

At the time of writing, there were no well-known drug interactions with xylitol.
