How much caffeine is in Celsius (Original)?
A 12 oz Celsius packs a serious 200 mg of caffeine, about two and a half Red Bulls in one sugar-free can. Marketed as fitness fuel, it hits well above the typical energy drink.

| 12 oz | 200 mg | 0 g |
≈ 2.5 Red Bulls; sugar-free.
Will Celsius (Original) affect your sleep?
Starting at 200 mg, Celsius needs around ten hours to fall under 50 mg, so a lunchtime can can still be active when you head to bed. Best kept to early in the day if you guard your sleep.
Heads up
At 200 mg, a second Celsius (Original) in a day pushes you toward the FDA’s 400 mg ceiling — and that’s before any coffee or tea. Log everything in the calculator to see your real daily total.
