Arginine

Arginine

L-Arginine is an amino acid known for its ability to aid in blood flow. It is important for the production of Nitric Oxide (NO).

Uses of Arginine

L-Arginine used to be the king in ingredients when it came to pumps. This has changed over the past decade, as Arginine has been studied quite extensively, which unfavorable results for vasodilation.

If you’re looking for a pump, we highly suggest taking a look at this study. The popular L-Citrulline is more effective than L-Arginine at increasing blood Arginine levels since it is absorbed much more efficiently than Arginine! So if you’re looking at to increase Arginine levels, don’t take Arginine, take L-Citrulline.

With all that said, Arginine is used to increase Nitric Oxide levels in the blood. You’re going to find L-Arginine in products such as pre-workouts, pump products, sleep aids, and male enhancement products.

In pre-workouts and pump products, it may increase blood flow. In pump products, it is pretty much the same idea.

As for sleep aids, Arginine has been shown to be low in people with sleep apnea. Therefore supplementing with it may help.

​As for male enhancement, increased blood flow may help in increasing erections. Simple to understand this one.
