The Active Ingredient Is: Nitrosigine (Arginine Silicate Inositol Complex)

Nitrosigine is a patented ingredient combining arginine silicate inositol, a clinically studied form used to support nitric oxide production in the body.

This form is designed for enhanced absorption and bioavailability, contributing to a more effective vascular response during exercise.

What Does Nitrosigine Do?

Nitrosigine participates in the nitric oxide pathway, supporting vasodilation and increased blood flow to working muscles during activity.

This mechanism helps with nutrient delivery and may contribute to more efficient performance and recovery in normal physiological contexts.
