L-Citrulline - Effects, Benefits, and Citrulline Powder from MST Nutrition
What is L-Citrulline?
L-Citrulline is a non-proteinogenic amino acid found in large quantities in watermelons. In the human body, it is converted into L-Arginine and subsequently into nitric oxide (NO) - a gas responsible for widening the blood vessels. This mechanism is crucial for blood flow, oxygen supply, performance, and the characteristic pump effect during strength training.
Unlike arginine, L-Citrulline is absorbed more steadily, remains in the bloodstream longer, and has a demonstrably stronger physiological effect [1].
Effects of L-Citrulline
The scientifically proven benefits of L-Citrulline's effects include:
Improved blood flow through increased NO production
Enhanced muscle pump during strength training
Increased endurance performance during exertion
Better nutrient supply to the muscles
Reduction of muscle soreness and faster recovery
These effects apply not only in sports but also to people with an amino acid deficiency, for whom targeted supplementation can significantly improve the effects of amino acids [2].
Citrulline effects in men
In addition to its use in sports, Citrulline offers relevant benefits for men's health:
Improved erectile function through increased blood flow
Support for testosterone metabolism (indirectly through improved nutrient utilization)
Combination with arginine for a synergistic effect on potency
Alternative to synthetic erectile dysfunction medications
Studies show that daily intake of L-Citrulline can lead to significant improvements in men with mild erectile dysfunction [3].
Citrulline Malate - Effective combination with malate
Citrulline Malate is a combination of L-Citrulline and malate (malic acid). This form supports not only NO production but also energy metabolism through the citric acid cycle.
Benefits of Citrulline Malate:
Greater energy availability during training
Improved training performance and fatigue resistance
Ideal for strength and endurance sports
Longer-lasting and more sustainable effect than pure citrulline [4]
Citrulline + Arginine - Enhanced effect through combination
L-Citrulline and L-Arginine act through the same physiological pathway: They increase NO levels in the blood. While arginine acts quickly, citrulline ensures long-lasting NO production.
Benefits of the combination:
Faster and sustained vasodilation
Synergistic effect for maximum impact
Particularly popular in pre- and intra-workout products
This combination is also specifically used in the area of libido and men's health [5].
Citrulline powder - intake and dosage
Goal Recommended daily dose
Muscle pump & Pre-workout 6–8 g citrulline malate before training
Men's health & Libido 2–3 g daily
Endurance & Recovery 4–6 g 30–45 min. before exercise
Note: It is best taken on an empty stomach or with easily digestible carbohydrates such as Cluster Dextrin for improved absorption.
