  • Patented arginine complex that raises the bar for heart and circulatory health



  • A bioavailable source of arginine and silicon



  • Go beyond ordinary arginine for superior cardiovascular support


Swanson Ultra Nitrosigine® is a patented complex that binds arginine with silicate, unlocking powerful synergistic effects. It helps build nitric oxide levels over time to support healthy circulation and blood vessel integrity.

For over 15 years, the amino acid arginine has been widely researched as a supporting agent for cardiovascular wellness. Silicon is a well-established biological element recognized for its importance in connective tissue. Nitrosigine provides the benefits of both, along with additional benefits from the unique combination.

Arginine is converted in the body to nitric oxide which causes blood vessels to dilate or expand, to allow for optimal blood flow through the circulatory system. Silicon is found concentrated within the arteries, where it helps make the inner lining of arterial tissue less permeable. Together they help blood vessels relax and open to ensure healthy blood flow while protecting the structure of blood vessel tissue for long-term health and function.

Nitrosigine has been clinically demonstrated to significantly raise nitric oxide levels, generating more blood flow to working muscles and supporting overall cardiovascular health. With continued use, Nitrosigine has been shown to build nitric oxide levels over time, offering a long-term solution for cardiovascular maintenance.

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Nitrosigine Inositol Stabilized Arginine Silicate is rated 4.6 out of 5 by 10.
Rated 5 out of 5 by from Excellent With Citrulline Malate! This supplement does it all it's supposed to do and more. It has all the benefits of arginine but it's a LOT more reliable and much longer lasting! If you want even greater benefits or if you haven't had a positive reaction yet, take it together with Citrulline Malate 2:1 for sale here on Swanson. I take both with juice away from foods. Citrulline Malate 2:1 powder is a bit bitter but juice takes that away. Remember that supplements just supplement the good habits you keep. You have to be proactive and disciplined with your health.

Rated 5 out of 5 by from An excellent supplement I suffer from the occasional 'effects' of overwork.... and this supplement is of unquestionable value

Rated 5 out of 5 by from The REAL Benefits Are... This product was designed first and foremost for cardiovascular support (nitric oxide production in the blood vessels). And to this end it is highly effective. For those of you who complain about the price or that it comes in pill form vs. capsule...stop complaining. You can't have it every way you want it. Just be happy that it is indeed VERY effective!

Rated 4 out of 5 by from Improves my workouts This helps me shorten my in between reps during weight lifting. I take 2 pills combined with swansons peak atp 2 pills. Works better togather than alone. However i wouldn't buy this at regular price, i paid half price and still feel it should be cheaper...
