SwissRX Nitric Oxide
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.


Foundational Support Meets Targeted Power
Use Nitric Oxide Pro daily for all-day vascular support. Add Nitric Oxide before key efforts for a 5-hour peak. Different pathways, better together.




How to Use SwissRX Nitric Oxide + Nitric Oxide Pro
Use Nitric Oxide Pro in the morning to build a 24-hour foundation of vascular support that improves blood flow, oxygen delivery, and recovery. Then layer in the original Nitric Oxide before key training sessions for a powerful 5-hour boost in endurance and performance.
AM Dose
Take 2 capsules of Nitric Oxide Pro with breakfast. This sets your vascular baseline for the day and supports recovery around the clock.
Pre-Workout Boost
Before a key session or race, take 4 capsules of SwissRX Nitric Oxide 30–60 minutes prior. This delivers a sharp 5-hour boost when performance matters most.
Train + Recover
You’re now supported through both long endurance efforts and peak intensity. No overlapping ingredients, no guesswork—just full NO coverage.
Repeat Daily
Make it a habit: Pro in the morning, Original before intensity. Your cardiovascular system will thank you.
