Why Supplement L Arginine?


At EraseDisease.com we get this question quite often – “why supplement l arginine?” L arginine is an amazing little amino acid that facilitates the production of nitric oxide. As an athlete, a weekend warrior, or a busy parent, there are two things you could always use more of; energy and endurance. At EraseDisease.com, we’re kind of cardiovascular buffs and also care about the heart health benefits that nitric oxide provides, but for the purpose of this article we’ll focus on the energy and endurance aspect l arginine and nitric oxide.


L Arginine

First off, let’s run a quick background check on l arginine. This amino acid synthesizes to produce nitric oxide. Nitric oxide causes the muscles to use less oxygen, which improves endurance. Nitric oxide also facilitates vasodilation, or the widening of the arteries, which improves healthy circulation, which gives you more energy. So, effectively, l arginine improves endurance and energy levels, while also improving heart health and cardiovascular efficiency.


Newest Study

The most recent study into the workings of l arginine on endurance took place at Exeter University. It was the second l arginine testing to be done at this University in recent years, and simply speaking it was a ‘re-test’ of previous findings.


FlashBack – In previous testing, researchers concluded that ‘acute l arginine supplementation reduces the O2 cost of moderate-intensity exercise and enhances high-intensity exercise tolerance.’ The published results went on to say…


A limitation of the present study was that the commercial L-arginine supplement we administered contained small amounts of other compounds which might also be considered ‘active’ or which might have acted synergistically with L-arginine. While we cannot exclude this possibility, we consider it to be unlikely given the similarity of our results to other studies in which NO availability was enhanced to a similar degree using pharmacological (47, 48) or dietary (1, 4) nitrate interventions.


Flash forward to the most recent study, in which the researchers decided to use ONLY l arginine. The results were quite different, showing that perhaps l arginine did not boost endurance and reduce the amount of oxygen needed as intensity increased. So the researchers dug a bit deeper and realized that in the previous study, the used a supplement cocktail, much like Cardio Juvenate Plus, that included, as Cardio Juvenate Plus includes, l citrulline and l carnitine. The published study goes on to say…


Thus, it is possible that the positive effects we observed were consequent to the independent effects of one, or the cumulative effect of several, of the nutrients provided or to a synergistic interaction between L-arginine and one or more of the other ingredients.


The team at EraseDisease.com found this new realization by the researchers incredibly intriguing. It seems that l arginine combined with l citrulline and l carnitine works better in terms of increasing energy and endurance than simply supplementing with l arginine alone. But we always knew that!
