Metabolic Nutrition Citrulline is a single-ingredient pump powder: 5,000mg of citrulline malate per scoop, unflavored, in 100g and 300g tubs. Citrulline is the go-to stim-free ingredient for supporting blood flow and training endurance, and 5g is a common pre-workout dose.† With no fillers, binders, preservatives or artificial ingredients, it adds to any pre-workout or plain water without changing the flavor much. It is made without gluten, dairy, egg, peanut, soy, shellfish, wheat or yeast, in a facility that processes those allergens.

About Metabolic Nutrition
Metabolic Nutrition is a sports nutrition brand known for its clean single-ingredient amino acids and its ultra cold-pressed line. The brand says it makes its supplements in its own manufacturing facility. Single ingredients like this one let you build your own pre-workout or top up a formula that runs light on citrulline. Plenty of popular pre-workouts carry well under 5g, so a scoop of this closes the gap.
Citrulline Malate 5,000mg
L-citrulline is an amino acid your body converts into L-arginine, which is then used to make nitric oxide. Nitric oxide relaxes blood vessels, which supports blood flow and the pump you feel during training.† Citrulline malate pairs citrulline with malic acid, which plays a part in cellular energy production. It has been studied for supporting repetitions to fatigue and reducing post-workout soreness in resistance training.†
Frequently Asked Questions
-
When should I take citrulline?
Metabolic Nutrition suggests taking 1 scoop 15 to 20 minutes before training. That gives it time to absorb before your first working set. Some people also take it on rest days for consistency, though most use it pre-workout only. Stick to the label's daily directions.† -
Can I add it to my pre-workout?
Yes, and that's one of the most common ways to use it. Check how much citrulline your pre-workout already has, then add this to reach your target. Because it's stimulant-free, it doesn't add any caffeine to your stack. It also works on its own for evening sessions when you want to skip stimulants entirely.† -
What does unflavored citrulline taste like?
Citrulline malate is tart and slightly sour on its own. Most people mix it into a flavored pre-workout, juice or an EAA drink to hide it. Mixed into plain water, it's drinkable but noticeably tangy. It dissolves easily with a quick shake. -
Is citrulline safe for tested athletes?
Citrulline is not on the WADA prohibited list. This product is a single ingredient with no stimulants listed. Tested athletes should still check with their sport's governing body, since this product doesn't advertise a third-party sport certification. When in doubt, ask before you compete.
