How Much Caffeine Is in a Can of Sprite? | Zero, Actually

If you’re scanning a soda can for caffeine content, you might assume every fizzy drink gives you a little jolt. Sprite breaks that pattern — and has since its debut in 1961.

The short answer is simple: Sprite has no caffeine at all. But the longer answer touches on why you may have thought otherwise, how it stacks up against other sodas, and what you’re actually getting from that crisp, lemon-lime can.

Why Some People Think Sprite Has Caffeine

Sprite is made by The Coca‑Cola Company, a brand best known for its flagship cola, which packs 34 mg of caffeine per 12‑ounce can. Because Coke and Sprite sit side by side on shelves and share a corporate parent, it’s easy to assume the caffeine carries over. It doesn’t.

Another reason: many clear sodas — like Mountain Dew — do contain caffeine. But Sprite belongs to the smaller group of lemon-lime drinks that are intentionally caffeine‑free, alongside 7UP and Starry.

The confusion is understandable, but the manufacturer has always marketed Sprite as a caffeine‑free, 100% natural‑flavor beverage. You won’t find any stimulant in the ingredient list.

How Much Caffeine Is in a Can of Sprite Compared to Other Sodas

Placing Sprite on the soda caffeine spectrum makes its zero‑mg status stand out. Most popular sodas contain at least some caffeine, often in amounts that can add up over the day.

• Coca‑Cola (12 oz): 34 mg of caffeine — the classic cola that started the comparison.
• Pepsi (12 oz): 38 mg, slightly more than Coke.
• Mountain Dew (12 oz): 54 mg, one of the highest among mainstream sodas.
• Dr Pepper (12 oz): 41 mg, another cola‑like option with a caffeine punch.
• Sprite, 7UP, Fresca, A&W Root Beer (12 oz): All 0 mg — the caffeine‑free crowd.

Sprite ranks at the very bottom of caffeine charts for popular sodas. If you’re avoiding caffeine for medical reasons, sleep sensitivity, or personal preference, it’s a safe choice.

What You Actually Get in That Can — Sugar and Calories

Even without caffeine, a 12‑ounce can of Sprite delivers 140 calories, all from sugar (about 38 grams). That’s roughly 9–10 teaspoons of added sugar — the same amount found in a can of Coca‑Cola. The energy you feel after drinking Sprite comes purely from that sugar spike, not from any stimulant. Healthline’s deep dive into soda nutrition notes that the much caffeine the form of sugar‑fueled alertness, which fades faster and can lead to a crash later.

The American Heart Association recommends limiting added sugar to no more than 36 grams per day for men and 25 grams for women. One can of Sprite already exceeds the daily limit for women and comes close for men. If you’re watching your sugar intake, the caffeine‑free label doesn’t mean calorie‑free.

Sprite Zero, the diet version, offers the same zero‑caffeine profile with no sugar and fewer calories. It’s also made with 100% natural flavors but uses artificial sweeteners (aspartame and acesulfame potassium) to stay sweet.

Beverage (12 oz)	Caffeine (mg)	Calories
Sprite	0	140
Coca‑Cola	34	140
Pepsi	38	150
Mountain Dew	54	170
7UP	0	140
Fresca	0	15

As the table shows, caffeine content varies widely, while calorie counts cluster around 140–170 for regular sodas. The main difference between Sprite and most other caffeine‑free sodas is its brand recognition and availability.

Who Should Consider Going Caffeine‑Free With Sprite

Choosing a caffeine‑free soda like Sprite makes sense for several specific groups. Here’s who may benefit most.

1. People with caffeine sensitivity: If even moderate caffeine (30–50 mg) makes you jittery or disrupts sleep, Sprite is a safe option.
2. Anyone on certain medications: Some drugs interact with caffeine. A zero‑mg soda avoids that risk entirely.
3. Pregnant or breastfeeding women: Health authorities often recommend limiting caffeine during pregnancy. Sprite fits within a low‑caffeine lifestyle.
4. Those managing anxiety or heart conditions: Caffeine can exacerbate palpitations or anxiety. Zero caffeine means one less variable.

For these groups, Sprite offers the familiar soda experience without the stimulant. The trade‑off is the high sugar load, so the diet version may be more appropriate for regular consumption.

Caffeine‑Free but Not Stimulant‑Free — Understanding the Full Picture

Sprite contains no caffeine, but it still delivers a quick energy burst through its sugar content. Mayo Clinic’s comprehensive caffeine chart confirms that Sprite caffeine content is zero, but its nutrition panel shows 38 grams of sugar per can. That sugar enters your bloodstream rapidly, causing a rise in blood glucose followed by an insulin spike — and often a subsequent energy dip.

For comparison, a 12‑ounce can of unsweetened iced tea has 0–5 mg of caffeine and 0–2 grams of sugar, while a typical energy drink (8 oz) contains 80–100 mg of caffeine plus 20–30 grams of sugar. Sprite falls into a middle category: no stimulant but high sugar. If your goal is reducing caffeine without increasing sugar intake, Sprite Zero or plain sparkling water may be better options.

The bottom line on Sprite’s effects: you won’t get a caffeine lift, but you will get a sugar rush. That distinction matters for anyone trying to manage energy levels or blood sugar.

Drink Type	Caffeine (12 oz)	Sugar (g)
Sprite (regular)	0 mg	38
Sprite Zero	0 mg	0
Unsweetened iced tea	0–5 mg	0
Energy drink (8 oz)	80–100 mg	20–30

The Bottom Line

A 12‑ounce can of Sprite contains 0 mg of caffeine, making it a true caffeine‑free soda. Its energy comes entirely from 38 grams of sugar, which adds up quickly. If you’re avoiding caffeine, Sprite is a fine option — but if you’re also watching sugar, the Zero version or sparkling water might serve you better.

Your choice depends on what you’re after: a familiar lemon‑lime soda without the stimulant, or a lower‑sugar alternative that still skips caffeine. Check the nutrition facts on any new soda, because sugar loads vary even among caffeine‑free drinks.
