Unlock Your Performance Potential

Nitric oxide (NO) dilates arteries and increases blood flow to working muscles, enhancing endurance and faster recovery. We like to think of using NO as that “Oh, these intervals feel good” experience.

But traditional NO boosters often fail to provide adequate doses or only brief rises in levels.

Your Nitric Oxide Options

SwissRX Nitric Oxide uses proven ingredients (L-Citrulline, grape seed extract, quercetin) for targeted 5-hour NO boosts. Take four capsules 30-60 minutes before breakthrough training sessions or priority events when you need maximum support.

SwissRX Nitric Oxide Pro. The game-changer. Enhanced with Noxa24®, this formula provides nitric oxide support for up to 24 hours from a single dose.

It targets multiple pathways—both nitric oxide synthase (NOS) and nitrate > nitrite > nitric oxide—supplementing key precursors to support the entire cycle for consistent, long-lasting benefits traditional supplements can’t match. Take two capsules in the morning with a meal for all-day cardiovascular support.

The Bundle (The Power Couple) is a Strategic combination that delivers a 24-hour foundation plus targeted performance boosts using non-competing pathways for maximum cardiovascular benefits. Your baseline stays optimized throughout training blocks, recovery periods and daily activities.

Better Together

Different pathways complement rather than compete: Nitric Oxide Pro targets the nitrate pathway for sustained support, while Nitric Oxide amplifies the NOS pathway for a performance peak. This provides complete coverage with flexible dosing—consistent baseline with targeted boosts for enhanced training, better endurance, reduced fatigue, increased time to exhaustion and faster recovery.

Strategic Usage

Daily: SwissRX Nitric Oxide Pro in the morning for a 24-hour foundation
Before key sessions: Add SwissRX Nitric Oxide 30-60 minutes before important races or breakthrough training

Nitric Oxide Test Strips

You can’t improve what you don’t measure.

Get instant results in 10 seconds—collect saliva on the strip, wait 10 seconds, compare to the chart – no lab visits, no waiting, just immediate feedback. Test first thing in the morning and before key workouts to determine your levels, since everyone reacts differently.
