Quick answer: Yes, Pepsi Max has caffeine. How much depends on where you buy it — a US can (sold as Pepsi Zero Sugar) has 38 mg, a UK/Australian 330 ml can has about 42.6 mg, and in Canada it can run as high as 69 mg per 355 ml can. That’s a bigger gap than most people expect from the “same” drink, and it trips up almost everyone searching for a straight number — so let’s clear it up region by region.
Wait — Is It “Pepsi Max” or “Pepsi Zero Sugar”?
Both. Same drink, different name depending on where you live, and this is honestly the #1 source of confusion around its caffeine content.
- In the US, PepsiCo renamed Pepsi Max to Pepsi Zero Sugar back in 2016. The name changed; the zero-calorie, zero-sugar cola stayed.
- In the UK, Europe, Australia, and New Zealand, it’s still sold as Pepsi Max.
- In Canada, you’ll find it labeled either way, and — this is the part most articles get wrong — it appears to use a different, higher-caffeine formula than the current US version.
So “how much caffeine is in Pepsi Max” doesn’t have one universal answer. It has three or four, depending on the can in front of you.
Caffeine by Region (12 oz / 355 ml equivalent)
| Region | Product name | Caffeine (12 oz / 355 ml) |
|---|---|---|
| United States | Pepsi Zero Sugar | 38 mg |
| UK / Europe / Australia / NZ | Pepsi Max | ~42.6 mg (per 330 ml can, scaled) |
| Canada | Pepsi Max / Zero Sugar | ~69 mg (higher-caffeine formula) |
A note on the Canadian figure: PepsiCo doesn’t publish per-country caffeine breakdowns the way US labels do, so this number comes from independent lab-tested trackers rather than an official spec sheet. If you’re in Canada and caffeine-sensitive, check your can’s label directly — formulas can and do change.
Caffeine by Can and Bottle Size
Since a lot of people are searching for specific sizes rather than the standard 12 oz can, here’s the breakdown across common serving sizes:
US (Pepsi Zero Sugar):
- 12 oz (355 ml) can: 38 mg
- 16.9 oz (500 ml) bottle: ~53 mg
- 20 oz (591 ml) bottle: ~63 mg
- 2 L bottle: ~215 mg total (about 38 mg per 12 oz serving)
UK / Australia (Pepsi Max):
- 250 ml can: ~32 mg
- 330 ml can: 42.6 mg
- 375 ml can (AU/NZ standard): ~48 mg
- 500 ml bottle: ~64.5 mg
- 600 ml bottle: ~77 mg
- 750 ml bottle: ~97 mg
These per-size figures are scaled from the disclosed per-can amount and can vary slightly by market and bottling run — always a good idea to check the label if you’re counting precisely.
Does Pepsi Max Come in Different Flavors — and Does Caffeine Change?
Yes. Pepsi Max Cherry, Pepsi Max Vanilla, and other flavor variants generally carry the same caffeine content as the standard Pepsi Max/Zero Sugar in that market — flavoring doesn’t typically add or remove caffeine. If you’re drinking a flavored variant, use the regional figure above as your baseline, but double-check the can, since limited-edition flavors occasionally use a different base formula.
How Pepsi Max Compares to Other Drinks
| Beverage | Serving Size | Caffeine (mg) |
|---|---|---|
| Pepsi Max (US, as Zero Sugar) | 12 oz | 38 |
| Pepsi Max (UK/AU) | 330 ml | 42.6 |
| Pepsi Max (Canada) | 355 ml | ~69 |
| Regular Pepsi | 12 oz | 38 |
| Coke Zero Sugar | 12 oz | ~34 |
| Brewed Coffee | 8 oz | 80–95 |
| Red Bull | 8.4 oz | ~80 |
Even at the higher Canadian figure, Pepsi Max still lands well below a cup of coffee or an energy drink — it’s a moderate lift, not an energy-drink substitute.
Will Pepsi Max Actually Make You Feel More Awake?
For most people, yes, a little. At 38–69 mg depending on region, one can is roughly a third to two-thirds the caffeine of a cup of coffee — enough to take the edge off an afternoon slump or help you feel more alert during a drive, but not enough to produce the jittery, wired feeling a stronger energy drink might. How noticeable the effect is depends heavily on your personal tolerance, how recently you’ve had other caffeine, and your body weight.
How Many Cans Can You Drink Per Day?
The FDA’s general guideline for healthy adults is up to 400 mg of caffeine per day. Here’s what that looks like in Pepsi Max terms:
- US formula (38 mg/can): up to ~10 cans before hitting the guideline — though drinking that much soda for other reasons (sugar substitutes, carbonation) isn’t advisable regardless of caffeine.
- UK/AU formula (42.6 mg/can): around 9 cans.
- Canadian formula (69 mg/can): around 5–6 cans.
These are ceiling numbers, not targets — they assume zero caffeine from any other source that day (coffee, tea, chocolate, medication). Most people feel the effects of caffeine well before reaching these limits.
Pregnant? Caffeine-Sensitive? Here’s What to Know
- Pregnancy: Health guidelines generally recommend capping caffeine at 200 mg/day. One can of Pepsi Max, in any region, fits comfortably within that — but it adds up fast alongside coffee or tea, so track your total daily intake rather than treating each drink in isolation.
- Teens and children: Should have considerably less caffeine than adults; sensitivity is higher and effects on sleep and focus are more pronounced.
- Sleep-sensitive drinkers: Caffeine can linger in your system for 5–6 hours. A can in the early afternoon is generally fine for most people; one in the evening is more likely to interfere with falling asleep.

Frequently Asked Questions
Does Pepsi Max have caffeine? Yes — every standard version does. The exact amount ranges from about 38 mg (US) to 69 mg (Canada) per 355 ml can, depending on region.
Is Pepsi Max the same as Pepsi Zero Sugar? Yes, in the US. Pepsi Max was renamed Pepsi Zero Sugar in 2016; it’s the same drink under a different name. Outside the US, it’s still sold as Pepsi Max.
Why does Pepsi Max have more caffeine in some countries? PepsiCo uses region-specific formulas. The US version was adjusted in 2023 to match regular Pepsi’s caffeine level, while some other markets — notably Canada — appear to have kept a higher-caffeine formula.
How much caffeine is in a 2L bottle of Pepsi Max? Scaled from the 12 oz/355 ml figure, a 2 L bottle works out to roughly 215 mg total in the US formula, or higher in markets using the stronger formula — check your local label for the precise per-serving amount.
Does Pepsi Max have more caffeine than coffee? No. An 8 oz cup of brewed coffee has 80–95 mg of caffeine, which is more than even the highest regional Pepsi Max figure.
Can drinking Pepsi Max affect my sleep? It can, especially if consumed within 5–6 hours of bedtime. This is more relevant for the higher-caffeine regional formulas (like Canada’s) than the 38 mg US version.
