Nitric oxide (NO) is a really simple molecule—just a nitrogen atom bound to an oxygen atom. In spite or because of this, NO is a powerful actor in the body, going so far as to win “Molecule of the Year” from The American Association for the Advancement of Science in 1992. NO plays a role in regulating blood pressure, enhancing erectile ability and boosting brain function.
It also helps bodybuilders recover more quickly and effectively from intense weight training. Nothing else on earth gets you hard and helps you think better at the same time, plus it has bodybuilding benefits. Heck, maybe NO should’ve been awarded molecule of the century.
NO is a potent vasodilator, meaning that it helps your veins relax, allowing more oxygen and nutrients to pass through your circulatory system. This is particularly critical for bodybuilders because during and after workouts your muscles need more blood, oxygen and nutrients for better pumps, more strength and, ultimately, faster, more effective recovery.
