Citrulline (powder or capsules)

Citrulline, a non-essential amino acid named after the watermelon from which it was first isolated, has become an essential supplement in sports nutrition. At Herba Barona, your specialist shop at 10 rue Théophile Roussel, Paris, we offer four citrulline options available in powder and capsules, suited to athletes of all levels and to anyone looking to support their blood circulation and physical performance.

Citrulline’s mechanism of action relies on its conversion into arginine in the kidneys, and then into nitric oxide at the level of the endothelial cells. Nitric oxide is a powerful vasodilator that relaxes blood vessel walls, thereby improving blood flow to working muscles. This increased vasodilation allows for a better supply of oxygen and nutrients, while also helping clear metabolic waste products such as lactic acid.

Paradoxically, citrulline supplementation proves more effective than direct arginine supplementation for raising plasma arginine levels. Orally ingested arginine undergoes significant first-pass liver metabolism, which breaks down a large proportion of it before it reaches systemic circulation. Citrulline, by bypassing this liver metabolism, reaches the kidneys intact, where it is converted into arginine efficiently and over a sustained period.

The benefits of citrulline for athletes are numerous and well documented. Improved muscle pump during resistance training, often simply called “the pump,” is the most immediately noticeable effect. Beyond this aesthetic aspect, citrulline is associated with delaying the onset of muscle fatigue, improving endurance during prolonged efforts, speeding up post-exercise recovery, and reducing the muscle soreness felt in the days following an intense workout.

Athletes in the Paris 12th arrondissement who train regularly can get advice at Herba Barona on the optimal dosage and timing of citrulline. The malate form, which combines citrulline with malic acid, is particularly interesting because malic acid takes part in the Krebs cycle and contributes to aerobic energy production. A dose of six to eight grams of citrulline malate, taken thirty to sixty minutes before training, is generally recommended for optimal effects.

Beyond sports performance, citrulline has interesting applications for cardiovascular health and fatigue management. Its vasodilatory action helps maintain healthy blood pressure, while its role in the urea cycle supports the elimination of ammonia, a metabolic waste product whose build-up is linked to feelings of physical and mental tiredness.

Our citrulline powders offer the flexibility of a personalised dose and excellent value for money, while the capsules offer the convenience of use on the go. All our products are free from colourings, artificial flavourings and unnecessary excipients. We exclusively select citrulline produced through plant-based fermentation, guaranteeing optimal purity and compatibility with vegetarian and vegan diets.
