Xylitol is a naturally occurring sugar alcohol that is commonly used as a sweetener in food products. It is found naturally in certain fruits and vegetables, and is also produced by the human body in small amounts.
In protein powders and other food products, xylitol is used as a low-calorie alternative to sugar. It has a similar sweetness profile to sugar, but contains fewer calories and does not raise blood sugar levels as much as sugar does. Xylitol is also known to have dental health benefits, as it helps to reduce the risk of tooth decay and cavities.
Xylitol is generally considered safe for consumption, but it can cause digestive issues such as bloating, gas, and diarrhea in some individuals when consumed in large amounts. It is important to note that xylitol is toxic to dogs and can cause severe health issues or even death, so it should be kept away from pets.
