Pre-workout
A pre-workout is a powder or capsules taken 20–40 minutes before training. A typical recipe: caffeine, citrulline or arginine, beta-alanine, taurine, tyrosine, sometimes creatine and vitamins. Recipes differ a lot, so look at the contents, not just the name.
The key number is caffeine per serving, from 0 to 400 mg. Every product with caffeine carries the mandatory warning with its amount. Stimulant-free products have their own section.
FAQ
How much caffeine is in a pre-workout?
Usually 150–400 mg per serving. The exact figure is on the card and the product page.
Can I take a pre-workout in the evening?
Caffeine products are best not taken late in the evening. There are stimulant-free options.
Why does my skin tingle?
That is beta-alanine. The feeling is harmless and passes in about an hour.
Can it be combined with coffee?
Better not: count the whole day's caffeine. EFSA considers up to 400 mg a day safe for healthy adults.
Who should not take pre-workouts?
Children, pregnant or breastfeeding women, people sensitive to caffeine, with heart rhythm problems or high blood pressure.
