What Is L-Citrulline?

September 10, 2026 · 4 min read

L-Citrulline is one of Virilix's named amino acids. Here's a plain-language look at what it actually does.

What It Is

L-Citrulline is an amino acid the body uses in its own natural nitric oxide production pathway, working alongside L-Arginine.

Why It's Included

L-Citrulline supports the body's own L-Arginine production, contributing to healthy circulation and blood flow.

How Virilix Uses It

L-Citrulline is paired with L-Arginine in Virilix's formula, doubling up on circulation support alongside the energy and hormone-pathway ingredients.

An Honest Note

Individual results vary, and L-Citrulline is one of 21 named ingredients working together, not a standalone solution. Virilix is not a treatment for erectile dysfunction.
