What is the healthiest energy drink?

After 12 weeks of testing, Drink Reboot came out on top for everyday health. It contains zero sugar, just 5 calories, and pairs microencapsulated caffeine with functional ingredients like creatine, Alpha GPC, L-Tyrosine, and L-Theanine — a formula closer to a functional beverage than a traditional energy drink.

Which energy drink has the least sugar?

All of our top picks are zero-sugar formulas. Drink Reboot, Celsius, Alani Nu, Ghost, C4, Red Bull Sugarfree, Monster Zero, Reign, and Rockstar Zero all contain 0g of sugar. Prime Energy also contains zero sugar.

Which energy drink gives the smoothest energy?

Drink Reboot delivered the smoothest experience in our tests, thanks to microencapsulated caffeine that releases gradually, combined with L-Theanine to take the edge off. Most reviewers reported a clean lift with no crash.

Is Drink Reboot good for everyday use?

Yes. At 140mg of caffeine per can, Drink Reboot sits well within FDA's recommended daily limits for healthy adults and is one of the lowest-calorie options in our ranking. Its functional ingredients (creatine, Alpha GPC, L-Tyrosine, L-Theanine) are designed for daily use rather than occasional spikes.

How much caffeine is in Drink Reboot?

Each can of Drink Reboot contains 140mg of microencapsulated caffeine — comparable to a strong cup of coffee but released more gradually, which most testers reported as a smoother and longer-lasting lift.

Celsius

Fitness-focused thermogenic energy
