Perplexity One 16 fl oz can of Monster Energy Zero Sugar, the green-and-black can, has 10 calories, 0g sugar and 160mg of caffeine. The US label lists 6g of carbohydrate, which includes the erythritol it is sweetened with alongside sucralose and acesulfame potassium, plus 380mg of sodium. It is a different can from Monster Zero Ultra (the white can), which has about 137 to 150mg of caffeine.

Macronutrient Breakdown
NUTRITIONIST'S INSIGHT
Treat the can as 160mg of caffeine with almost no calories. For most adults one can is fine, but two cans reach 320mg before any coffee, and the drink has no protein or fiber to slow anything down. The 380mg of sodium is about 17% of the daily limit, which matters if you drink several a week. If you drink it daily, watch the caffeine total and the sweeteners rather than the calories: erythritol is the one with an open cardiovascular question.
Myth Busters
MYTH #1: Zero sugar means it has no effect on blood sugar
TRUTH: The label shows 0g sugar and 10 calories, so the drink gives you almost no glucose. The 6g of listed carbohydrate is mostly erythritol, which the body absorbs poorly. Caffeine can still raise blood sugar a little in some people, so people with diabetes should check their own readings.

MYTH #2: Zero Sugar is the same as Zero Ultra
TRUTH: They are two cans. Zero Sugar is the green-and-black can with 160mg of caffeine per 16 fl oz, and Zero Ultra is the white can, which retailers and third-party tests list at about 137mg per can. Sweeteners overlap, so the calories and sugar match. Monster Energy Zero Sugar; Monster Energy Zero Ultra 473 ml ingredients
MYTH #3: A zero-calorie energy drink is safe to drink all day
TRUTH: Calories are not the limit here. The FDA puts 400mg of caffeine a day as the level most healthy adults can handle, and each can has 160mg, so three cans pass it. Spilling the Beans: How Much Caffeine is Too Much?; Caffeine: How much is too much?
MYTH #4: Sugar-free energy drinks help you lose weight
TRUTH: Swapping a 54g-sugar original can for this one cuts about 200 calories. The WHO found no lasting body-fat benefit from non-sugar sweeteners in the long run, so it helps only if it actually replaces a sugared drink.

NutriScore by Health Goals
| Health Goal | NutriScore | Why This Score? |
|---|---|---|
| Weight Loss |  | 10 calories per can replaces about 210 calories in the sugared original. It stops at B because the WHO found no lasting weight benefit from sweeteners and the drink gives no fullness. Monster Energy Zero Sugar; WHO advises not to use non-sugar sweeteners for weight control |
| Blood Sugar Control | | 0g sugar and 10 calories mean little glucose reaches the blood. It is B, not A, because caffeine affects some people's glucose and erythritol has an open cardiovascular question. Monster Energy Zero Sugar 16 fl oz label and ingredients; The artificial sweetener erythritol and cardiovascular event risk |
| Heart Health |  | 380mg of sodium per can is about 17% of the daily value, and a 2023 Nature Medicine study linked high blood erythritol to cardiovascular events. The study was observational, so it signals a question rather than proof. Monster Energy Zero Sugar 16 fl oz label and ingredients; The artificial sweetener erythritol and cardiovascular event risk |
| Hydration |  | The 160mg of caffeine and 380mg of sodium make it a poor stand-in for water. Mayo Clinic notes caffeine's mild diuretic effect is small, but the can adds no benefit that water lacks. Caffeine: How much is too much?; Monster Energy Zero Sugar 16 fl oz label and ingredients |
| Daily Energy | | 160mg of caffeine is a standard dose and is within the FDA's 400mg daily limit for one can. The B reflects that a second can starts to crowd that limit. Monster Energy Zero Sugar; Spilling the Beans: How Much Caffeine is Too Much? |

Blood Sugar Response - Monster Zero Sugar (1 can / 473 mL)
With 0g sugar and 10 calories, one can of Monster Zero Sugar gives the body almost no glucose to absorb, so a healthy adult's blood sugar stays near its fasting baseline for the 2-hour window. Caffeine can cause a small rise in some people, and the 6g of listed carbohydrate is mostly poorly absorbed erythritol, so count the can as close to 0g of carbs.

Estimated Blood Glucose Response (mg/dL)
Illustrative curve for a healthy adult drinking one can on an empty stomach. Meals eaten with it and individual insulin sensitivity change the real curve.
How to flatten the spike
- Log it as about 0g of usable carbs and carb-count the food you drink it with.
- Drink it with a meal that has protein and fiber so the meal's carbs rise more slowly.
- Use it to replace a sugared energy drink, not on top of one.
- If you have diabetes, check your glucose 1 to 2 hours after your first can to see how caffeine affects you.
- Stop at two cans a day at most to stay under 400mg of caffeine.
Cultural Significance
Monster Energy Zero Sugar is the sugar-free version of the original green-and-black Monster that Hansen Natural launched in 2002. It sits between the full-sugar original and the lighter-tasting Ultra line, and it is a staple at gyms, gaming desks and night shifts. Shoppers often confuse it with the white Zero Ultra can, which is why the two have separate pages.
