NOW Foods BetterStevia Granulated Packets is a zero-calorie, low glycemic, alternative sweetener that makes a perfect substitute for table sugar and other sweeteners. Unlike chemical sweeteners, NOW Foods BetterStevia is a certified organic stevia extract. BetterStevia utilizes a whole leaf extract that retains the pure sweetness of real stevia, as opposed to other products that have only isolated fractions, such as Rebaudiana A (Reb A). Each packet sweetens just like a packet of sugar. BetterStevia Tastes Better, not Bitter!
