Two pre-workouts can look identical on the shelf and differ by more than double in caffeine per scoop. Because caffeine drives most of what people feel from a pre-workout, that one number should decide more of your purchase than flavor or branding.
Here is how to find it, what the typical ranges are, how it compares to coffee, and how to use the Fitnos catalog to compare listed doses.
Where to find the number
Look at the supplement facts panel for caffeine anhydrous (or a named caffeine source) with an amount in milligrams per serving. Brands that disclose it per ingredient are easier to compare. If caffeine is inside a proprietary blend with a single total weight, the individual dose is not disclosed.
Typical ranges
- Lower-stimulant products often list roughly 100–150 mg per serving.
- Mid-range products commonly list around 150–250 mg.
- High-stimulant products list 300 mg or more; some list much higher amounts per full serving.
- Stimulant-free products list none and rely on other ingredients.
For reference, a typical cup of brewed coffee is often cited around 80–100 mg, though it varies. A high-stimulant scoop can equal three or more cups at once.
Choosing a dose for you
Consider what else you drink during the day, how late you train, and how sensitive you are. Training in the evening with a 300 mg scoop is a common cause of poor sleep, which in turn hurts training. If in doubt, a lower-caffeine or stimulant-free product is the safer starting point. Anyone with a medical condition, who is pregnant, or who takes medication should ask a professional first.
Beyond caffeine
Citrulline and beta-alanine are the other ingredients shoppers commonly compare; beta-alanine is the source of the tingling sensation some products produce. Again, disclosed per-ingredient doses are what make comparison possible.
Compare listed caffeine, serving size, and price across two or three pre-workouts.
Frequently asked questions
- Is 200 mg of caffeine a lot for pre-workout?
- It sits in the middle of the range many products list. Whether it is a lot for you depends on tolerance and total daily intake.
- What if the label doesn't list caffeine?
- It may be inside a proprietary blend. If you want to know your dose, choose a product that discloses individual amounts.
- Does stimulant-free pre-workout do anything?
- It omits caffeine and relies on ingredients like citrulline and beta-alanine. See our stimulant-free guide for what to look for.
