What Should Be in a Pre-Workout (and at What Dose)
Short answer: Most pre-workouts are built from a few ingredients: caffeine, citrulline, beta-alanine, betaine, and sometimes tyrosine and electrolytes. What separates a good label from a bad one is whether each ingredient is printed at a real dose or hidden inside a blend. If you cannot see the milligrams, you cannot know whether it is dosed at the amounts used in the research.
The usual ingredients
- Caffeine: the main stimulant. Common amounts run from about 100 to 300 mg. More is not automatically better.
- Citrulline, or citrulline malate: often used around 6 to 8 grams in studies.
- Beta-alanine: commonly around 3.2 grams a day. It can cause a harmless tingle (more below).
- Betaine: often around 2.5 grams.
- Tyrosine, electrolytes, and others: these vary by product.
The label trick to watch for
Many pre-workouts list these under a single blend total, so you see one big number and none of the individual doses. That lets a brand use a real dose of cheap caffeine and a pinch of the costly citrulline, and you cannot tell the difference. A clear label prints each ingredient with its own amount. If you want to weigh two tubs honestly, put their labels side by side and read the milligrams, not the marketing.
Why the tingle happens
Beta-alanine can cause a pins-and-needles feeling on the skin, called paresthesia. It is well documented and harmless. It is a sign the beta-alanine is present, not a problem.
FAQ
How much caffeine is in a pre-workout? Usually 100 to 300 mg. Check the label and your own tolerance.
What causes the tingle? Beta-alanine. It is harmless.
How do I know if a pre-workout is under-dosed? If the ingredients are hidden in a blend, assume you cannot verify the doses.
The Valenco take
Across our core lineup, Valenco prints the dose of every ingredient on the label, and you can check the numbers on our lab results. Whatever pre-workout you buy, find the milligrams next to each ingredient before you judge it. valenco.org.
