Fat-Reduced Cocoa Powder — present in chocolate-flavored variants for rich flavor and smooth texture.
Soy Lecithin (Emulsifier) — helps the powder mix smoothly and evenly in water, milk, or other liquids.
Sweeteners (Acesulfame Potassium, Sucralose) — sweeten the formula without adding significant sugar or calories.
