Nitrosigine®: The Patented Arginine and Silicon Complex for Vascular Pumps and Performance Nitrosigine® is a patented and clinically studied arginine-silicon-inositol complex, developed by the US-based Nutrition 21 (now part of Balchem). Unlike standard L-arginine, its unique structure binds the amino acid arginine to the mineral silicon via inositol, creating a stable molecule that is absorbed and released more efficiently. This mechanism supports optimal nitric oxide (NO) production, leading to significant and noticeable vascular pumps, improved blood flow to muscles, enhanced nutrient and oxygen delivery, and consequently improved endurance, strength, and recovery during training. It is the standard for ingredients that support vasodilation. All products containing Nitrosigine® can be found on the official Nowfit Sports Nutrition website in Switzerland, Canton of Ticino, and Lugano.
