Nobel* laureate and heart expert Dr. Lou Ignarro discusses Niteworks®, a refreshing powdered drink mix that supports the body’s production of an incredible molecule called Nitric Oxide, or NO.
Niteworks® was created to be taken nightly to promote the natural formation of NO, since NO levels are lowest at night. NO is a crucially important molecule in the cardiovascular system. It’s also the body’s most important antioxidant and regulator of cardiovascular health and function.
NO’s major role is in opening, or widening, the blood vessels, also known as vasodilation. Wide, flexible blood vessels help maintain blood flow to vital organs, which supports overall cardiovascular function.

Essentially, NO is a “heart healthy molecule.” And Niteworks® supports the body’s natural ability to produce NO, which promotes improved circulatory, immune and nervous system function.

Niteworks® supports the body in a number of ways. It supports blood flow, for the healthy function of the heart, brain and other organs.† It helps keep blood vessels toned, flexible and youthful for improved circulation.† And it also supports healthy blood pressure levels already within a normal range—an important part of supporting overall cardiovascular wellness.†

Exercise and a healthy diet are important to keeping your NO levels high. And adding Niteworks® is a smart strategy for anyone looking to support heart health. While Niteworks® doesn’t provide the body with NO, it does support the body’s natural production of NO.
