What is L-Citrulline?
L-Citrulline is a naturally occurring amino acid. Its name comes from Citrullus, the Latin for watermelon, the fruit it was first isolated from. Unlike most amino acids it is not used to build protein; instead the body converts it into another amino acid, L-arginine, in the kidneys.
General role
That conversion is why citrulline became popular with athletes. Arginine is used by the body to make nitric oxide, a molecule involved in the normal widening of blood vessels. Supplement makers found that taking citrulline is a practical way to raise arginine, and it is now a standard ingredient in pre-workout drinks and circulation-focused men's formulas.
Why Vigueur Active includes it
Vigueur Active is built for active men, and citrulline is one of the most recognised ingredients in that world. Including 150 mg per capsule – the joint-largest dose in the formula alongside L-Carnitine – gives the product credibility with men who already know the ingredient from sports nutrition, without the need to mix a powder.
How it relates to the product's purpose: Stamina and physical readiness are core to the 'active' promise on the label. Citrulline sits at the centre of that.
Where it sits in the formula
Vigueur Active contains eight active ingredients in one vegetable capsule: vitamin B3, zinc, L-Citrulline, L-Carnitine, pine bark extract, maca root extract, grape skin extract and saffron extract. L-Citrulline is one piece of that. Related ingredients worth reading about are L-Carnitine and Pine Bark Extract, and the complete breakdown with all amounts is on the Vigueur Active ingredients guide.
