SwissRX Nitric Oxide

Boost your endurance and oxygen capacity for a full 5 hours with this unique performance booster.

The science behind Nitric Oxide being a major performance booster is clear. By boosting Nitric Oxide you dilate your arteries and can increase your blood flow to working muscles, resulting in increased endurance and easier recovery.  That's why supplements like Sur Alt Red, BeetElite, and others have become so popular with endurance athletes.

The problem is that most Nitric Oxide supplements use L. Arginine to do this. While this gives you a short spike in Nitric Acid 3 hours after ingestion, the effect fades very quickly.

SwissRX has figured out (through clinical trials) that if you use L. Citrulline, it will signal your body to create L. Arginine (versus supplementing it). This creates the same peak level of Nitric Oxide, but you get to maximum levels after only 2 hours and the level is maintained for a full 5 hours with no decline.

SwissRX has combined L. Citrulline with a patented form of Grape Seed Extract that has been shown to activate your body's production of Nitric Oxide (via eNOS) and help maintain arterial dilation. 

Bottom line: SwissRX has the most effective Nitric Oxide booster we've found on the market. It will open your blood vessels and increase oxygen flow, allowing you to go faster and harder for longer.

How We Use It

We use 4 capsules 1 to 2 hours before training.

The SwissRX Story

We set out to find a supplement company we could trust for the world's top endurance athletes: a company that has the same obsession with quality and performance as our athletes do. Our quest led us to SwissRX. SwissRX takes a "spare-no-expense" approach to procuring the highest quality Pharmaceutical Grade Ingredients. Only 3% of supplement companies go through the rigorous testing required for pharmaceutical grade labeling, SwissRX happens to be one of them. But they don't stop there; whenever possible, they use the exact ingredients used in medical studies, the same ones that many other companies point to in research, but don't use due to their price. We love SwissRX because our athletes can rest assured knowing that they are getting the identical ingredients that were proven to be effective in previous studies.

Simply stated, SwissRX products work better because they contain better ingredients.
