Pre-Workout Supplements: What Works and What's Just Marketing

Most pre-workout labels have 10-15 ingredients on them. Maybe four of those actually do anything at the dose they’re using. The rest is there to make the label look good.

What Actually Works

Caffeine — The best-proven ingredient in all of sports nutrition. Studies keep showing it helps with strength, power, and endurance. 200-400mg, taken 30-60 minutes before training, is the effective range for most people.

Creatine — Works great, doesn’t need to be taken pre-workout specifically. Timing barely matters. Still a fine thing to have in a formula.

Beta-alanine — Helps you push through the burn in sets that last 1-4 minutes. Causes a harmless tingly feeling at higher doses — that’s normal, not a bad reaction. You need to take it every day, not just before workouts, for it to build up and work.

Citrulline malate — Decent evidence it reduces how tired you feel and lets you squeeze out a bit more volume in a session.

What’s Mostly Filler

“Proprietary blends” — If a label hides ingredients behind a blend name with no individual doses shown, be skeptical. It’s usually a way to list something cool-sounding at a dose too small to matter.

BCAAs — If you’re already eating enough protein, adding BCAAs on top does nothing extra. This one gets way oversold.

Random “focus” ingredients — Most fancy-sounding focus blends don’t have real, dosed research behind them.

How to Pick One

Skip anything with a proprietary blend. Look for a label that shows the actual dose of each ingredient. A good pre-workout is really just caffeine, beta-alanine, and citrulline malate (maybe creatine too), each at a real dose. That’s it.

Bottom Line

You don’t need pre-workout to train hard — caffeine alone covers most of the benefit. If you do use one, check that it shows real doses instead of hiding behind a long ingredient list.
