How Monster Energy Zero affects Your Blood Sugar Level

Ever wonder if Monster Energy Zero spikes your blood sugar? I put it to the test with a continuous glucose monitor (CGM). I drank a full 500ml can—labeled sugar-free with zero carbs—and tracked my glucose response. My blood sugar started at 5.0 mmol/L (90 mg/dL) and rose mildly to 5.8 mmol/L (104 mg/dL) after one hour. That’s a gentle 0.8 mmol/L or 16% increase—well within the healthy range. If you’re looking for a sugar-free energy drink that doesn’t mess with your blood sugar, this might be a solid choice. Just don’t forget it still packs a caffeine punch!

Metabolic Health Insights 🔬

This CGM test highlights the potential of sugar-free drinks like Monster Energy Zero to support better postprandial glucose control. With no measurable carbs and only a slight rise in glucose, it’s a promising option for individuals managing insulin resistance or aiming to prevent type 2 diabetes. Maintaining stable blood glucose after eating—or drinking—is key for metabolic flexibility and gut health. Continuous glucose monitors help you understand your body’s response in real time, and drinks that avoid sharp glucose spikes can reduce glycemic stress. While caffeine can have individual effects, the absence of sugar makes Monster Zero metabolically friendly for most.
