There is about 300 mg xylitol per chewie. To put it in context, you'll get that much xylitol from eating a few strawberries.
Xylitol is a sweetener found naturally in many fruits, berries, cauliflower, pumpkins, oats, and mushrooms. A small amount is also produced by the human body. It is commonly found in chewing gums and toothpaste.
Xylitol can also reduce bad bacteria in the gums (hence their use in dental products) and slightly improve the amount of healthy probiotics in the gut.
The amount of Xylitol that you would ingest from taking this Omega 3 gummy is comparable to consuming fruits and vegetables stated above.
There is no known risk for humans ingesting Xylitol at these levels. The only concern is if you ingest 50 grams or more per day, at which level, you may experience digestive distress. To ingest that much, you would have to consume dozens of boxes of this product in one sitting.
