How it works
Nitric Oxide Ultra is a premium dietary supplement designed to enhance blood flow and support vascular health. Featuring a potent blend of CranLoad® and citrulline, this formula targets nitric oxide production, which is essential for healthy blood vessel function and overall cardiovascular well-being. Nitric oxide plays a crucial role in maintaining blood vessel dilation, which is necessary for optimal circulation and oxygen delivery throughout the body. This product is ideal for those looking to improve athletic performance, enhance endurance, and promote healthy cardiovascular function.
CranLoad® is a unique fruit blend developed through an extensive research collaboration with the Institute of Nutrition and Functional Foods (INAF) and Université Laval in Quebec, Canada. This innovative blend combines cranberry and grape seed extracts, both of which are rich in proanthocyanidins and polyphenols—potent antioxidants that support endothelial health. These compounds work to improve vascular function by enhancing blood flow and promoting the dilation of blood vessels. Clinical studies have shown that CranLoad® helps support healthy flow-mediated dilation (FMD), a process that is closely linked to nitric oxide production.
Incorporating citrulline into the formula further amplifies the effects on nitric oxide production. Citrulline has been shown to boost plasma arginine levels more effectively than arginine supplementation itself. Arginine is a precursor to nitric oxide, and by increasing its availability in the body, citrulline helps optimize nitric oxide production, leading to improved blood vessel function and circulation. This combination of ingredients makes Nitric Oxide Ultra a highly effective supplement for those seeking to improve circulation, support cardiovascular health, and enhance physical performance.
Whether you are an athlete aiming to improve endurance, an individual focused on maintaining healthy blood pressure levels, or someone looking to promote overall vascular health, Nitric Oxide Ultra offers a scientifically-backed solution. With its powerful blend of natural ingredients and cutting-edge research, this product provides a safe and effective way to support healthy nitric oxide levels, blood vessel dilation, and overall cardiovascular function.
