Erythritol is a sugar alcohol that is commonly used as a low-calorie sweetener in a variety of food and beverage products, including protein powders. It is derived from natural sources, such as fruits and vegetables, and is often used as a sugar substitute due to its low glycemic index and calorie content.
In protein powders, erythritol may be used as a sweetener to enhance the taste and flavor of the product. It is often used in combination with other sweeteners, such as stevia or monk fruit extract, to provide a more natural-tasting sweetness without adding calories.
Erythritol is generally considered safe when consumed in moderate amounts. It has been approved for use by the US Food and Drug Administration (FDA) and is generally recognized as safe (GRAS). It is also not metabolized by oral bacteria, which means that it does not contribute to tooth decay as regular sugar does. However, some individuals may experience digestive issues, such as bloating or gas, when consuming erythritol in large amounts.
