Pre-workout blend
Also known as: pre-workout stimulant, pre-workout shot
A pre-workout is a blend taken before training, typically containing caffeine, beta-alanine, citrulline, creatine, betaine, tyrosine and electrolytes. Its effect comes mainly from individual ingredients at adequate doses, so quality depends on the label.
What it is used for
- alertness and performance from caffeine – strong evidence for caffeine
- endurance in high-intensity efforts (beta-alanine) – moderate evidence
- blood flow and performance (citrulline) – weak to moderate evidence
Forms and how they differ
stimulant
contains caffeine, often 150–300 mg per serving – check the label
caffeine-free (stim-free)
suits evening training, relies on citrulline, beta-alanine etc.
shot
smaller liquid serving, usually with caffeine
proprietary blend
without listed amounts its effectiveness cannot be judged
Pairs well with
Water, a light pre-training meal; good hydration.
Do not combine / separate
Do not combine with coffee, energy drinks or other stimulants. Beta-alanine may cause harmless skin tingling.
Watch out for
Not suitable during pregnancy, breastfeeding or for adolescents. With high blood pressure, heart disease, anxiety, kidney or liver disease, or when taking medicines, consult your doctor.
Safety
Total caffeine should not exceed 400 mg per day (EFSA, healthy adults) and 200 mg at once; do not exceed the label dose.
Practical tip
Start with half a serving and do not use it before every session to avoid tolerance.
