With a sweetness almost 600 times that of regular sugar, the sucralose in Yellow Ecosticks is an excellent zero calorie sweetener made from table sugar. Extracted from sugar but not sugar itself, sucralose won't spike blood sugar and has no calories.

Uniquely shaped, Ecostick sugars and sweeteners are designed to use less packaging materials than traditional packets, while still delivering the same amount of sweetness to beverages. 100% non-GMO, Ecosticks are an easy way to make an environmentally friendly change, helping to save space and reduce waste.
