The row that matters is sugars: one can spends 61% of a whole day's reference intake. The calories are entirely carbohydrate — no fat, no protein — which makes Monster nutritionally closer to a melted dessert than to a drink that happens to contain caffeine.

The 500 ml can

The stealth factor is the can itself. At 500 ml it holds half as much again as a standard 330 ml soft-drink can, so "one can" of Monster means roughly a can and a half of cola's worth of liquid. People compare cans one-to-one; the cans aren't one-to-one.

Flavours and Ultra

Monster variants calories comparison (alt: "Monster flavours and Ultra calories comparison")

The sugared flavours cluster tightly, 44-48 kcal per 100 ml:

Picking a "lighter" sugared flavour saves 15 kcal at best. The only switch that changes anything is to the Ultra/Zero line at 1-3 kcal per 100 ml — single digits for a whole can. That's not a marketing rounding trick; sweeteners genuinely carry almost no energy, so the 227-kcal gap between Original and Ultra is real.

Sugar: 14 cubes a can

A green can carries 55 g of sugar — roughly 14 cubes. The NHS advises adults to stay under 30 g of free sugars a day, so one Monster spends nearly two days' allowance before breakfast, lunch or anything else gets a look in. The World Health Organization's healthy diet guidance draws the same line on free sugars globally.

There's caffeine in the can too, which is its own subject. But the calories and the sugar are the measurable bill, and water, tea and lower-sugar drinks are the comparison the NHS keeps pointing back to. If the Monster habit is daily and the goal is weight, the Ultra swap alone deletes almost 1,600 kcal a week.

How does Monster compare?

(alt: "Monster vs coke, latte and Red Bull calories comparison")

DrinkPer serving
Monster Ultra (500 ml can)~8 kcal
Latte (mug)68 kcal
Cappuccino (cup)68 kcal
Red Bull (250 ml can)80 kcal
Coke (330 ml can)139 kcal
Monster Original (500 ml can)235 kcal

The verdict: for an energy lift at the smallest calorie cost, a latte or cappuccino at 68 kcal beats every sugared can here — and a cup of tea does the caffeine job for 13. Monster Original tops this table mostly because its can is the biggest: per 100 ml it's 47 kcal against Red Bull's 32 and coke's 42, so it loses on both size and density, just not by the margin the can totals suggest.

Monster FAQ

How many calories in a 500 ml can of Monster?

235 kcal for Monster Original, from the label's 47 kcal per 100 ml. All of it is carbohydrate — 55 g of sugar and no fat or protein — plus a modest 0.25 g of salt. The fruit flavours sit within about 15 kcal of the same figure.

How many calories in Monster Ultra?

About 8 kcal per 500 ml can. The Ultra and Zero lines run 1-3 kcal per 100 ml because they're sweetened instead of sugared, and sweeteners contribute almost no energy. The 227-kcal gap to an Original is the biggest single saving on the energy-drinks shelf.

How much sugar is in a Monster?

55 g per 500 ml can of Original — roughly 14 sugar cubes, and nearly twice the 30 g of free sugars the NHS advises adults to stay under for an entire day. The Ultra line replaces the sugar with sweeteners and drops to effectively zero.

Is Monster bad for you?

One can delivers 235 kcal and almost two days' free-sugar allowance, alongside a substantial caffeine dose — that's the factual load. As an occasional drink it's a big treat; as a daily habit the sugar alone outpaces NHS guidance. The Ultra line removes the sugar issue but not the caffeine.

Monster or Red Bull — which has more calories?

Monster, on both counts. A 500 ml Original is 235 kcal against a 250 ml Red Bull's 80, and Monster is denser too: 47 kcal per 100 ml versus Red Bull's 32. Drink a Red Bull can and you've had about a third of a Monster's calories.

How many calories in Mango Loco?

48 kcal per 100 ml — about 240 per 500 ml can, making it the heaviest of the mainstream flavours by a whisker. Pacific Punch runs 46 per 100 ml (~230 a can) and The Doctor 44 (~220). The differences between sugared flavours are pocket change.

How many calories in Monster per 100 ml?

47 kcal per 100 ml for Original, with the sugared flavours spanning 44-48 and Ultra/Zero at 1-3. Per 100 ml, Original is denser than cola (42) — and the can is half as big again, which is why the per-can totals diverge so sharply.

Is Monster Zero really zero calories?

Close enough to count as zero: 1-3 kcal per 100 ml, so mid-single digits for a full can. UK labelling lets drinks that low describe themselves as zero, and the rounding hides nothing meaningful. Sugar-wise there's genuinely none to speak of.
