The Zero Sugar and Low-Calorie version of Original Monster Energy. People have been blowing up our inbox for years asking for a low-calorie Monster. We got it, but this isn’t soda pop, dude. Making a low-calorie, zero sugar drink that’s good enough to earn the Monster ‘M’ isn’t that easy. Finally, with a re-tooled energy blend, new sweetener system and after hundreds of failed flavors, we absolutely got it right. Monster Energy’s proprietary energy blend has the ideal combo of the right ingredients in the right proportion to deliver just the right kick. Monster Zero Sugar helps fight fatigue, improves mental performance and focus, and motivates you to work (play) harder, so generally, you feel pretty damn good.
