Energy Drinks Compared: Caffeine, Sugar & Price Per Can

Most of what's in Canned Energy & RTD is already zero sugar — brands like Alani Nu, Ryse and Ghost build their whole RTD range sugar-free. Use the Zero sugar column above to check any specific can before you buy, since a few carbonated and RTD-protein crossover lines still carry sugar.

Caffeine per can splits into rough bands. 80–120mg sits closer to a strong coffee — good for study or a work session without the crash. 150–200mg is a proper training dose, similar to a Moderate Stim pre-workout. 200mg+ is max territory, on par with our Strong Stim and Max Stim ranges — check the Caffeine column above before stacking a can with a pre-workout.

A canned energy drink is the RTD shortcut — no scoop, no shaker, just crack it and go. A pre-workout is dosed powder you mix yourself, usually with a wider ingredient stack (citrulline, beta-alanine, creatine) built specifically for training. If you're chasing gym performance rather than a caffeine hit, a scooped pre-workout will out-dose almost every can on this list.

For a desk session, look lower on the Caffeine column and toward the Zero sugar ticks — a can in the 80–150mg band is plenty without derailing an afternoon. Before training, most people reach for the 150mg+ cans or step up to a dedicated pre-workout from our Pre-Workout range for the pump and endurance ingredients a plain energy drink doesn't carry.

Several lines here — Ryse, Ghost and the Nexus PER4M RTD — come in 12-packs priced close to case RRP, which is where the $/serve column pays off: buying the case usually works out cheaper per can than singles. Check the Pack options column to see which flavours have a 12-pack, and compare $/serve rather than sticker price when deciding between a single can and a case.
