Flavor concentrates are a great alternative to traditional syrups and sweeteners. They come in liquid form or powder, and they're lower in calories, carbs and sugars than their sugary counterparts. Flavor concentrates can be used to flavor beverages like coffee or tea (or even water!) without adding any calories or carbs.
Some of the most popular flavors include vanilla extract, hazelnut syrup and almond syrup--but there are hundreds of others available depending on your preferences!
