How does pre-workout work?
A pre-workout supplement is a combination of ingredients that affect different body systems:
- Energy and focus — caffeine and other stimulants increase alertness and motivation
- Durability — beta-alanine and citrulline help delay fatigue and perform more repetitions
- Pump (muscle pump) — nitric oxide (NO) precursors dilate blood vessels, bringing more blood to the muscles
- Power — creatine and betaine support the growth of strength indicators
Main ingredients and their effects
Caffeine (150-400mg)
The main ingredient in pre-workout. Increases energy, focus and endurance. The optimal dosage is 3-6mg per kg of body weight (~200-400mg for a 70kg person). If you are sensitive to caffeine, choose a stim-free option.
Beta-alanine (2-5g)
An amino acid that buffers muscle acidification. Delays fatigue and helps you do more reps. Causes a characteristic tingling sensation on the skin (paresthesia) — this is safe and normal.
L-citrulline / Citrulline malate (4-8g)
A precursor to nitric oxide, which dilates blood vessels. Result: better muscle pump, more nutrients to the muscles and improved endurance. Citrulline malate also contains malic acid, which supports energy production.
L-arginine (3-6g)
Another NO precursor. Citrulline is actually better in terms of bioavailability, but arginine is cheaper and works just as well. Best for pumps.
Keep an eye on it. on ingredient dosages, not just their presence. Many cheap pre-workouts contain the right ingredients, but in too small amounts. For example, less than 4g of citrulline or less than 2g of beta-alanine will not produce a noticeable effect.

How to use pre-workout?
Dosage and timing
- 20-30 minutes before training — mix one serving (~200-300ml with water) and drink
- Start with half a portion when you try a new product — assess your caffeine tolerance
- Do not exceed the recommended dose. — more does not mean better results
When not to use
- 6 hours before sleep — caffeine disrupts sleep even if you don’t realize it
- On an empty stomach — may cause nausea. Eat at least a light snack 30-60 minutes before
- Every day — your body gets used to caffeine. Take a break for 1-2 weeks from time to time to regain sensitivity
If you train in the evening (after 6pm), choose stim-free pre-workout like OstroVit Arginine or ICONFIT CREA Shortcut . Caffeine affects sleep even 6+ hours after consumption, and poor sleep means worse recovery and results.
Frequently asked questions
Is pre-workout dangerous?
A quality pre-workout in moderate doses is safe for healthy adults. The main risk is caffeine overdose — so always start with half a serving when trying a new product. If you have heart problems, high blood pressure, or other health concerns, consult your doctor.
Does a beginner need a pre-workout?
A beginner can do just fine without it for the first few months. But if you feel your energy is low and your motivation needs a boost, try a moderate option like OstroVit PUMP 300g (14.90€) or stim-free ICONFIT CREA Shortcut (€17.90).
Why do I feel a tingling sensation on my skin?
This is the beta-alanine effect (paresthesia). Completely safe and normal — it means the beta-alanine has started working. The tingling usually goes away within 15-20 minutes. If it bothers you, choose a product with a lower beta-alanine content.
Does pre-workout need to be used in cycles?
Yes, it is wise to take a break of 1-2 weeks from time to time for pre-workouts containing caffeine. The body builds up a tolerance to caffeine and the effect decreases. The break restores sensitivity. Stim-free products can be used continuously.
Can pre-workout replace coffee?
Pre-workout contains caffeine, but it’s not just ”stronger coffee.” In addition to caffeine, there are ingredients that specifically support exercise performance (citrulline, beta-alanine, etc.). Don’t drink coffee and pre-workout together — that’s too much caffeine.
