Nitrate supplementation – ramp up the less well-known NO pathway to boost performance and health

 

Nitric oxide (NO) boosting “pre-workout” supplements based on L-arginine have been – and still are – quite popular among many fitness enthusiasts and athletes. While it’s true that arginine is a nitric oxide (NO) precursor and NO is a potent vasodilator [1, 2], most studies in healthy adults have not unequivocally supported the marketing hype that arginine supplementation increases muscle blood flow and/or performance [3-5]. In my previous article “The Arginine Paradox” I explained why.
 
In this article I will cover the less well known, albeit highly significant, NO generating process, the nitrate-nitrite-NO pathway. This new NO producing pathway holds a lot of promise and supplements that target it will probably replace the current arginine based NO boosters in the near future[6, 7].
 
The nitrate-nitrite-NO pathway is especially interesting in that it not only has performance enhancing effects in healthy folks – as well as in people with risk factors – but also offers cardiovascular protection, regardless of baseline health status [7-10].
