The honest truth about pre-workout supplements (without the marketing hype)
The pre-workout aisle is a marketing minefield. Every label screams "extreme energy" and "explosive pumps" — but most products quietly underdose the ingredients that actually work. Here's a clear-headed guide.
Ingredients that genuinely work
1. Caffeine (clinical dose: 150–300 mg)
The most studied performance enhancer on the planet. Improves focus, perceived effort, and endurance. Effective dose is 3–6 mg per kg bodyweight — for most adults, that's 150–300 mg. Many pre-workouts list "caffeine blend" without disclosing the actual mg. Avoid those.
2. Creatine monohydrate (clinical dose: 3–5 g daily)
The most well-researched supplement after caffeine. Boosts strength, power output, and recovery. Best taken daily — not just on training days. 5 g per day for two weeks "loads" your muscles to peak; after that, 3 g daily maintenance is enough.
3. L-Citrulline (clinical dose: 6–8 g)
Increases nitric oxide for better blood flow ("the pump") and reduces muscle soreness. Most products dose at 1–2 g — completely ineffective. Look for 6 g or more.
4. L-Carnitine (clinical dose: 2–3 g)
Helps your cells use fat as fuel — particularly useful for cardio and fat-loss phases. Our L-Carnitine effervescent delivers 500 mg per tablet — take 2 tablets pre-workout for the clinical dose.
5. Beta-Alanine (clinical dose: 3–5 g)
Buffers lactic acid build-up so you can squeeze out more reps. Causes that harmless tingling sensation. Effective at 3–5 g daily.
Ingredients that are overhyped
- "Proprietary blends": If you can't see the exact mg of each ingredient, the dose is almost certainly too low to work.
- BCAAs: Useful if you train fasted; otherwise redundant if you eat enough total protein.
- "Nootropic" blends: Tyrosine and L-theanine have evidence — most "brain blends" do not.
- Glutamine: Marketed for recovery but very weak evidence in healthy lifters.
The simple, evidence-based stack
For most people, a pre-workout doesn't need to be complicated:
- 200 mg caffeine (or a strong coffee)
- 3–5 g creatine monohydrate (daily)
- 6–8 g L-citrulline OR 1 g L-carnitine + 1 g L-arginine (taken together pre-workout)
That's it. Save your money on the rest.
