Nitric Oxide Ultra (stick packs) provides similar benefits as Nitric Oxide Ultra (capsules), with enhanced support from higher potency citrulline and added nitric oxide cofactors including magnesium, taurine and vitamin C. Research indicates that citrulline increases plasma arginine in a dose dependent manner and to a greater degree than arginine supplementation. Unlike arginine, citrulline is not metabolized before it reaches systemic circulation. Research indicates that citrulline and CranLoad™ promote blood flow and lactate clearance during high-intensity exercise, offering a capacity for enhanced recovery. Taurine is included for its multifaceted vascular support properties. Research suggests that taurine promotes vascular cell health, cytokine balance, and nitric oxide production. In a randomized, double-blind, crossover trial, supplementation with taurine for two weeks promoted arterial flexibility and flow mediated dilation. Magnesium promotes healthy blood flow by supporting nitric oxide production, calcium channel activity, and endothelial function. Ascorbic acid is included to enhance nitric oxide activity and provide blood vessel endothelial antioxidant protection.*
