It is a dietary supplement designed to increase the body’s natural nitric oxide (NO) production. Increased NO helps widen blood vessels, enhance blood flow, improve oxygen delivery, and support better exercise performance.

“Nitric oxide (NO) boosters” don’t usually contain nitric oxide gas directly; instead they supply nutrients/precursors (like amino acids or nitrates) which your body uses to produce NO.

NO boosters are used 30–60 minutes before a workout “pre-workout” to maximize blood flow during exercise.

Yes. Foods high in nitrates (beetroot, spinach, arugula) and antioxidants enhance NO production naturally.
