Doctors Preferred Nitric Oxide Supplement - Blood Flow and Energy - 90 Vegan Tablets

Nitric Oxide Advantage is formulated to help skyrocket your body’s own nitric oxide production—supporting blood flow, circulation, vascular health, and overall superior performance to nitrate-heavy beetroot juice*. Here’s what makes it different. Nitrosigine is a clinically validated ingredient shown to support blood flow through its effects on flow-mediated dilation (FMD), a key marker of vascular function. It also helps increase blood arginine levels for up to 6 hours—supporting nitric oxide production when your body needs it most. Compared to beet-based nitric oxide support, Nitrosigine has been shown to deliver 4X greater impact on blood flow than the average nitrate effect from beetroot juice^. S7 takes things further. This plant-based blend is clinically validated to increase nitric oxide by up to 33.87% after 90 days—helping support sustained nitric oxide levels over time, not just a short-term boost. The result: better support for circulation, vascular function, and cardiovascular health—along with noticeable benefits for energy and cognitive health. It’s also been studied for its ability to support cognitive performance, especially after intense physical activity. And you get antioxidant support from resveratrol, plus S7 to help fight free radicals, reduce oxidative stress, and support a healthy inflammatory response. No beet loading. No guesswork. Just targeted, clinically validated key ingredients working with your body to boost nitric oxide levels for enhanced blood flow and performance. *Beet equivalents are estimated based on published averages of nitrate content in fresh beetroot and may vary by variety, growing conditions, and preparation method.
