3D Energy vs Celsius: which has more caffeine?

3D Energy carries more total caffeine per serving (200mg per 16 oz can vs 200mg per 12 oz can), but ounce for ounce Celsius is actually the stronger drink at about 17mg per fluid ounce against 12. Which one "has more caffeine" depends on whether you measure the container or the concentration.

3D Energy vs Celsius: the numbers

Sources: 3D Energy's figure is verified in our 3D Energy caffeine guide against Caffeine Informer (source); Celsius's figure is verified in our Celsius guide against Celsius essential facts (source).

Which one should you pick?

Pick Celsius when you want the lighter dose or a slower ramp, and 3D Energy when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.

For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.

Every drink in this comparison against Celsius

Barista Life runs a separate page for each of these matchups. This table puts all of them in one place so you can see where Celsius sits against the whole set, rather than one drink at a time.

Per serving or per ounce: which number answers your question

Per serving tells you what one container puts in you, and it is the number that matters if you are counting your day against a reference like the FDA's 400mg. Per fluid ounce tells you how concentrated the drink is, which is what decides how fast it arrives.

The two numbers disagree constantly, because serving sizes in this category run from under 2 oz to 16 oz. A drink can carry less caffeine in total and still be the stronger thing in the glass. Both columns are in the table above so you do not have to pick one.

Reaching the 400mg reference

The last column divides 400 by the caffeine in one serving, so it is the number of servings of that one drink to reach the FDA reference amount with nothing else in the day. Coffee, tea, soda and chocolate all count against the same total.

For context, the FDA cites 400mg of caffeine a day as an amount not generally associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
