Supports nitric oxide production and healthy blood flow*

Nitric Oxide Ultra (capsules) contains CranLoad® and citrulline to support increased nitric oxide production and healthy blood flow. Developed in collaboration with the Institute of Nutrition and Functional Foods (INAF) and Université Laval in Quebec, Canada, CranLoad® is a novel blend of cranberry and grape seed extract, rich in proanthocyanidins and polyphenols. Research has shown that CranLoad® may be beneficial for blood flow. 

In addition to being antioxidants, these compounds offer specific vascular support mechanisms that are associated with enhanced endothelial function. Research indicates that CranLoad® provides statistically significant support for healthy flow-mediated dilation (FMD), an effect similar to arginine administration. FMD reflects blood vessel dilation mediated by nitric oxide synthase (NOS), an enzyme that generates the endogenous vasodilator, nitric oxide. In one study, the peak increase in brachial artery diameter following CranLoad® supplementation was 2.8% at 60 minutes.

A similar physiological effect has been demonstrated with arginine. Citrulline is included to support nitric oxide production in the blood vessel endothelium and other tissues. Research indicates that citrulline increases plasma arginine in a dose-dependent manner and to a greater degree than arginine supplementation.*
