What is Xylitol used for?

Xylitol is a white substance that tastes sweet with only 2.4 kcal/gram (as compared to the value of almost 4 kcal/gram for sucrose). Its calories is about 40% lesser than sugars.

As such, this “sugar-free” sweetener is a common ingredient used to make chewing gum, mints, candies, diabetic friendly foods and even oral care products.

On food labels, it is loosely classified as a carbohydrate or “sugar alcohol”.

Xylitol has been approved for safety by the U.S. Food and Drug Administration as a non-nutritive sweetener.

Products with xylitol

As you shop through the supermarket, there will be shelves of food stuffs that will contain xylitol.

Where does Xylitol come from?

Xylitol is found in small amounts in many fruits such as plums and raspberries, and also vegetables, mushrooms and cauliflower.

It is also present naturally in your bodies – in fact, an average size adult manufactures up to 15g of xylitol daily during normal metabolism.

Xylitol comes from 2 main sources

Sources of Xylitol

Both processes start from xylan (hemicellulose) extracted from hardwoods or corncobs, which is hydrolyzed into xylose and catalytically hydrogenated into xylitol.

a. Corn-derived sources and corncobs

Corncobs as a source is more sustainable and environmentally friendly. Corncobs are a renewable resource that take about 5 months to regrow and the process uses hydrogen, hydrochloric acid and steam.

Look out for sources where their corn farmers remain strictly and proudly non-GMO (genetically modified organisms) and use no chemical fertilizers or pesticides.

They hand plant their corn between rows of vegetables and trees, rotating crops every season – ensuring top soil quality.

The extraction process has to go through strict standards with many levels of checks and filtrations to ensure that the finer crystallized xylitol is the purest.


b. Birch based xylitol

Using birch based process takes more effort and resources as birch takes up to 20 years to regrow. This drives up the price of Xylitol.

Also in this method of extracting the bark of birch, sulphuric acid is used and the waste products cannot be reused.

This is also less environmentally friendly because to harvest the birch, trees will have to be chopped down.

What is Xylitol in Toothpaste called?

What Other Names is Xylitol Known by?

Other names of xylitol include Birch Sugar, E967, Meso-Xylitol, Méso-Xylitol, Sucre de Bouleau, Xylitol, Xylit, Xylite, Xylo-pentane-1,2,3,4,5-pentol.


How does Xylitol work?

Xylitol cannot be fermented by bacteria such as Streptococcus mutans (the bacteria responsible for tooth decay and bad breath). 

The environment in your mouth when you eat food will become acidic and xylitol helps to reduce that acidity. That is why xylitol is always given after meals or sweet snacks. 

To start a plaque build-up, bacteria will feed on sugars from the foods that you eat, then as a by-product, plaque is formed. 

But because when Streptococcus mutans meet xylitol, they are not able to break the xylitol down, therefore plaque is reduced. Xylitol can also make plaque slippery so that it is easier to slip off when brushing. 


How can you use Xylitol?

Is Xylitol Bad for Teeth?

Besides being beneficial as a sugar alternative, xylitol also helps to boost dental health and helps prevent the buildup of plaque.

Plaque is formed when sugars in food interact with the bacteria in your mouth.

If you use xylitol, it is useless to these bacteria and they will have no resource to turn into plaque.

Even when you digest xylitol, the bacteria in your mouth will be starved to death because they absorbed xylitol and are unable to take in any more sugars.

That being said, xylitol is highly dangerous to dogs, so be sure to keep any xylitol away from pets and dogs.

For some exceptions, xylitol is quite well accepted by human bodies. The recommended consumption is 5 to 10 g per day, though a maximum limit could be 45g per day.

Some exceptions could be stomach upsets and diarrhea.

What are the benefits of using xylitol?

When used properly, xylitol can have the following benefits.

  • Reduces the growth of bacteria that cause cavities, by preventing bacteria from sticking to your teeth
  • Prevent plaque from forming
  • Increase the pH value in the mouth
  • Strengthen tooth enamel.

It does not break down as sugars do, so the bacteria party cannot start because there is no food (broken down sugars)  for them.

Can Xylitol help to remineralize your teeth?

Your saliva has the ability to remineralize your teeth naturally by replacing the minerals from your body.

When xylitol increases your saliva production, the basic amino acids and ammonia in saliva increases in PH value, and calcium and phosphate salts in saliva will repair weak enamel and make it harden.

Summing Up: Xylitol is safe in Toothpaste

So yes xylitol, derived from corncob or birch has been approved by FDA for use in many products like chewing gum, mints, and also toothpaste.

As a consumer, you make your decision to use xylitol after your own research.
