Details Sweetness is meant to be enjoyed. That's why Truvia created products meant to reduce sugar, not taste. The clean, sweet flavor contained in Truvia Original Calorie-Free Sweetener packets comes from nature in the form of the stevia leaf. Leaves don't dissolve well in beverages or baked goods, so we extract the sweetness from the stevia leaf. Because stevia leaf extract is 200x sweeter than sugar, we balance the sweetness with erythritol, a sweetener produced by fermentation. Erythritol is also found in fruits like grapes and pears. This gives you the white crystals you're used to without the calories. This 400-count box is perfect for coffee shops, restaurants, at work or in the office.
