Xylitol is truly the darling of sugar substitutes today. The American Dietetic Association touts its use, with this sugar alcohol sold alone and as a sweetener in a variety of processed foods. Health benefits include a reduced glycemic response compared with sucrose, increased absorption of B vitamins and calcium, and even a reduction in dental caries risk.
Consequently, people with blood sugar issues are flocking to processed foods containing this alternative sweetener as a way to satisfy that sweet tooth without the downside of exacerbating the risk factors for Metabolic Syndrome. This condition is known for the markedly increased likelihood of developing heart disease, stroke, and type 2 diabetes.
Even the healthfood community almost universally considers this sugar alcohol to be a healthy substitute for sugar. A primary reason is that it doesn’t directly contribute toward the growth of intestinal yeasts aka Candida.
Have you noticed that the check out aisles at health food stores are typically loaded with chocolates and other sweets containing at least some xylitol? The truth is that I have yet to talk with any health-conscious person who suggests to me any downside other than the potential for intestinal cramps if you get too much.
Xylitol is Naturally Found in Nature
Xylitol is, after all, a naturally occurring substance. Manufacturers of xylitol market it as derived from xylan. The fibers of many plants contain it, including berries, oats, beets, sugar cane and birch. Sounds pretty harmless at first glance.
The FDA has even granted xylitol GRAS (Generally Recognized As Safe) status. You can’t get any safer than that, right?
Manufacturing Process
It is true that xylitol is a naturally occurring substance. However, manufactured xylitol is another matter entirely. Food manufacturers produce it using the industrialized process of sugar hydrogenation. In order to hydrogenate anything, a catalyst is needed. In this case, Raney nickel is used which is a powdered nickel-aluminum alloy. (1, 2)
This poses the risk of heavy metal residue and contamination. Nickel, by the way, is a recognized carcinogen and aluminum is associated with the development of dementia. Heavy metals in the body are notoriously difficult to eliminate with frequent use of infrared sauna probably a good idea.
This alternative sweetener doesn’t seem quite so warm and fuzzy anymore, does it?
There is currently no literature on any detrimental health effects of consuming hydrogenated sugar. However, food manufacturers widely used hydrogenated fats for decades before the very damaging effects of cardiovascular health became widely known!
Given the violent industrialized process that is required to produce a hydrogenated sugar like xylitol, it would seem wise to avoid it based on the very poor track record of hydrogenated foods in general.
Most Xylitol Sourced from GMO Corn
While it is true that xylitol can be derived from the xylan of birch trees, xylan is also found in corn cobs. It is much cheaper to use corn instead of birch bark to derive xylitol and so what do you think manufacturers prefer? Corn, of course.
Therefore, unless the label of a xylitol-containing product specifically notes that it is from birch or another nonGMO source, xylitol is very likely from genetically modified corn or possibly GMO sugar beets.
This is the same problem as high fructose corn syrup (HFCS) and white sugar from beets. Food manufacturers rely heavily on these sweeteners in the production of sodas and sports drinks.
You get a dose of GMOs with every sip! More on GMO dangers including sterility and stomach holes at the provided link.
Usage Contributes to Gut Imbalance
The digestive process does not break down sugar alcohols like food. Rather, xylitol arrives intact into the intestines.
At that point, a process called “passive diffusion” takes place. This means that the xylitol draws water into the bowels. Only a partial breakdown is the end result. The unmetabolized portion ferments providing the perfect environment for undesirable bacteria to thrive and grow.
It is true that xylitol itself does not feed candida directly as sugar does. As a result, this artificial sweetener is even promoted as a useful part of the Candida Diet. Unfortunately, the fermentation of undigested xylitol in the gut most definitely can exacerbate yeast problems. Don’t be fooled by this argument!
This is exactly why consuming xylitol can make some folks so gassy and even trigger cramping and diarrhea. Gut pathogens having a heyday in your intestines give off a lot of smelly toxins!
Other Little Known Problems
Xylitol can contribute to acid reflux problems. As a result, those who have issues in this area should avoid it for that reason alone. Chronic acid reflux is a serious problem that can lead to cancer of the esophagus and larynx.
In addition, those who suffer from seizures of any kind should stay away from this alternative sweetener as it can increase the frequency of epileptic attacks.
Two Pieces of Xylitol Gum Can Kill a Rat?
According to unpublished lab tests, approximately 1.65 grams of xylitol kills a 100-gram rat half the time.
Two little pieces of xylitol gum contain about .7 – 1 gram. This is probably enough to meet the definition of rat poison.
Cavity Prevention
Many people are chewing xylitol gum due to compelling scientific evidence for cavity prevention. What about children, however?
Rami Nagel, author of Cure Tooth Decay, doesn’t even recommend xylitol gum for this purpose. His research for any long term safety data turned up the following:
- Epidemiology: No information found
- Teratogenicity: No information found
- Reproductive Effects: No information found
- Mutagenicity: No information found
- Neurotoxicity: No information found
In summary, using this modern substance officially renders you a guinea pig, my friend! It seems that any benefits of cavity prevention are outweighed by the fact that there is no actual safety data backing up its use.
Safe Uses of Xylitol
Given all the problems that consumption of xylitol can trigger, it seems best to bypass the use of this sugar substitute on a regular basis.
Can it ever be helpful? Does it have any benefits whatsoever?
Potentially so. The only time I personally would ever consider using xylitol is to help resolve a childhood ear or sinus infection in order to prevent the use of drug-based antibiotics.
There is evidence that this popular sugar alcohol can indeed help encourage a healthy balance of beneficial bacteria found in the ear canal and sinus cavities. Products like this incorporate xylitol for this purpose.
A therapeutic dose can help resolve infection in these areas quickly with no medication required.
Thus, if you choose to use it, make sure it is sparingly and therapeutically (not as food). Also, make sure it does not come from a GMO source like corn!

I did the same search and basically most are saying xylitol is the cure, not the problem.
I will test it on myself, but the science is very conflicting to me.
Many sites that promote xylitol as “the cure” do so as a covert marketing strategy to sell their xylitol based products. Beware!
I have suffered from chronic dry mouth for over a year. It can occur alongside rheumatoid arthritis, which I’ve had for 18.5 years. Oral medication helps somewhat, but the dry sensation in my mout and especially on my tongue never go away. I’ve been using over-the-counter lozenges and tablets several times a day for relief. They contain xylitol, which stimulates saliva. Lately I’ve been noticing an increase in heartburn symptoms, so today I googled “heartburn and xylitol”, which led me to your page. Are you or anyone out there aware of any alternate remedies for chronic dry mouth that do not contain xylitol?
If I have it around bed-time, I can’t sleep.
Dr. Tom O’Bryan put me on to researching Xylitol based on studies he had read.
Very surprised
Only heard good things about Xylitol from the local health food store.
If he has Juvenile Myoclonic Epliepsy, seizures often occur in the morning after waking up (or after waking up from a nap). If he gets these at night when he brushes as well as in the mornings, then it may be the tooth paste, but it might just be the nature of the seizures! Good luck with figuring it out!
I bought a bunch of the xylitol candy mints. I got it for the dental aspect mostly. it does not affect my stomach. it probably is a rip- off based on what the price is- do not know if it was a mistake to buy so much now. I learned recently that agave is just overpriced sugar and not good for you at all if you are using it regularly. Agave is very expensive, I am returning what I just bought- better off just buying honey or the cheap syrup. Agave can have long term problems and is to expensive- DR Axe says to avoid it- worse than regular pancake syrup. Basically we can not get around eating right and eating sugar substitutes will not work in the long term, we have to learn to just eat natural and good foods. Otherwise these companies make a huge mark-up on us and we could be hurting our health, if it is expensive and promising the moon, don’t buy it, you are being fleeced and maybe hurt health wise if you consume a lot of it. The thing that confuses this is the money, they will try to make money at any cost and they often do not know the truth themselves- or they plain lie- or they simply do not care because the money coming in is so good.
please refer to a study showing that xylitol contains heavy metals. What you have provided is nothing but speculation. Thanks.
I put two and two together this morning when my son with epilepsy had a seizure right after brushing his teeth. Tom’s of Maine toothpaste contains xylitol and 15 out of the last 32 seizures he’s had have been right around toothbrushing time, according to the tracker app I use. My mind is blown. I have an appointment with the neurologist in a couple of days and I’ve emailed Tom’s about it too. Can I ask your source for the connection between seizures and xylitol? I’m not finding a lot online other than in my epilepsy facebook group.
can only offer my 2 cents, but having read about the gum helping with general mouth health, I started chewing some after meals.
my teeth are actually starting to whiten in places where there were very small dark spots, and my mouth generally feels much cleaner too. I’m certainly not having any negative bloating or anything else, so, it works for me
Xylitol gum can be very helpful for some with oral health issues. It is therapeutic in some cases as mentioned in the post. It is best avoided in food though.
As an epileptic, aware of the neurotoxicity of the artificial sweeteners I’m shocked to hear xylitol is out as well, the epilepsy foundation members rave about it. How come this isn’t more well known. Could you explain the problem with it to me a little further please.
