But what is nitric oxide, why do athletes and doctors care about it, and do you really need a supplement to raise it? This article covers 6 simple facts.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_What_Is_Nitric_Oxide\"><\/span>1. What Is Nitric Oxide?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Nitric oxide is a gas the body makes in tiny amounts. It acts as a chemical messenger telling the muscles in blood vessel walls to relax, so vessels widen and blood flow improves. The scientists who discovered this role won the 1998 Nobel Prize in Medicine.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_How_the_Body_Makes_It\"><\/span>2. How the Body Makes It<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><strong>From arginine:<\/strong> via special enzymes in the vessel lining; citrulline supports this route because it is converted into arginine.<\/li>\n<li><strong>From dietary nitrate:<\/strong> mouth bacteria convert nitrate from vegetables into nitrite, which the body then turns into nitric oxide.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"3_Why_It_Matters\"><\/span>3. Why It Matters<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Helps regulate blood pressure.<\/li>\n<li>Supports blood flow to muscles during exercise.<\/li>\n<li>Plays a role in erections \u2013 which is why ED medicines work by enhancing its effect.<\/li>\n<li>Supports the health of the blood vessel lining.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"4_What_Lowers_Nitric_Oxide\"><\/span>4.
