FAQs
What does 2:1 mean?
It means two parts L-citrulline to one part malate. So a 3 g scoop of 2:1 citrulline malate contains roughly 2 g of L-citrulline. Check this ratio when you compare products, as some list pure L-citrulline instead of citrulline malate.
How much should I take before training?
ATP Science suggests 2 to 8 g of citrulline malate 30 to 60 minutes before a workout, which is roughly one to two and a half scoops. Starting at the lower end lets you see how you go before taking more.
Can I add it to my pre-workout?
Yes. It is unflavoured, so it mixes into water or a flavoured pre-workout. Check how much citrulline your pre-workout already contains so your total stays within the amounts on both labels. More options are in our L-citrulline range.
Is it suitable for vegans?
ATP Science lists it as vegan, gluten free, GMO free and sugar free. It is made by fermentation from non-GMO watermelon seeds, and it is sold unflavoured with citrulline malate as the only ingredient.
