Nutrition 21 offers two ingredients for natural energy, Nitrosigine and Lepidamax. Nitrosigine is a dietary complex of bonded arginine silicate that significantly boosts nitric oxide levels, a key factor in generating blood flow and vasodilatation in the body. “By decreasing arginase levels, an enzyme that breaks down arginine, Nitrosigine provides the body with a well-absorbed, long lasting form of arginine,” explained Jim Komorowski, the company’s chief science officer. “Nitrosigine is also a bioavailable source of silicon, a trace mineral that supports the flexibility of blood vessels. Together, these nutrients work to increase nitric oxide levels, and in-turn, improve vasodilation and blood flow. Through this mechanism, Nitrosigine may increase blood flow to sensitive tissues, such as working muscles and the brain, providing them with the nutrients and oxygen needed for optimal performance, mental focus and recovery….
