VasoSport is a stimulant-free pre-workout supplement that provides Citrulline Malate plus Agmatine Sulfate and Nitrosigine™ to deliver a superior, sustainable muscular pump effect to take your workouts to new heights!* Citrulline Malate combines 2 parts L-Citrulline, an amino acid that converts to arginine to produce nitric oxide (N.O.) in the body, with 1 part malic acid, a kreb’s cycle (citric acid cycle) intermediate which helps to produce energy.* Agmatine Sulfate, while a very effective vasodilator, can also inhibit nitric oxide synthase to prevent itself from being broken down, allowing it to remain active longer and also prolonging its pump-inducing effects.* Nitrosigine™, the third member of the vasodilating components within VasoSport, is inositol-stabilized Arginine ionically bonded with Silicon. This bond increases the vasodilating effects of Arginine while simultaneously boosting the blood vessel relaxation benefits of silicon.* This bonded material can remain active in the blood for up to 3 hours. Taurine serves as the electrolyte regulator, ensuring a proper balance of the added electrolytes are delivered to the muscles in order to keep them adequately hydrated.*
