Frequently asked questions

What does citrulline do in pre-workout?
Citrulline raises nitric oxide levels, which widens blood vessels to improve blood flow and give a bigger, fuller muscle pump during training.
What's the difference between L-citrulline and citrulline malate?
L-citrulline is the pure amino acid, while citrulline malate binds it to malic acid; both boost the pump, but doses differ, so people compare labels carefully.
How much citrulline should you take?
Common effective doses are around 6-8 grams of L-citrulline or 8 grams of citrulline malate, taken roughly 30-60 minutes before training.
