What is it?

Arginine is a supplement known for having a versatile array of positive effects on the body. There is some evidence to suggest that the supplement may help the body produce protein [1]. The supplement has also been known to have some positive effects on libido, though the results aren't conclusive [2].

Additionally, L-Arginine supplement has been known to aid in lowering blood pressure conditions in some individuals in some studies [5].

Overall, Arginine has the possibility of aiding in many different functions within the body, and it's been used to help boost the body's abilities in many different areas.

Top 3 Arginine Benefits

Possible benefits of L-Arginine include:

1. Arginine for Nitric Oxide Increase

Arginine is a direct precursor to Nitric Oxide, which is responsible for increased blow flow. This directly correlates to improved muscle pumps and may improve your performance in the gym. Additionally, high doses of arginine can raise insulin levels further increasing Nitric Oxide and blood flow [1].

2. Arginine for Growth Hormone Stimulation

Some studies have indicated that Arginine may very well stimulate the creation of a growth hormone in the body [1, 4]. Taking supplements to help stimulate growth can be of great use to athletes, since athletes will often need growth in various parts of their body depending on what their sport or area of interest is.

It's often a good idea to add supplements to overall growth regimens in exercise to try to create a positive feedback loop. This means that the more you exercise and promote growth that way, the more synergistic it could be with the supplement, increasing the benefit from the supplement which then increases the benefit from exercise and strength training, and so on.

Promoting growth in your body can significantly increase the abilities of any athlete, and it is especially valuable for promoting growth in areas of your body where that is difficult to accomplish with traditional training.

3. Arginine for Reducing Anxiety

Combining Arginine with lysine can have a positive effect on mental troubles such as stress and anxiety [6]. A large amount of mental anguish can result from stress being placed on an individual, and stress and anxiety are just some of the symptoms that result from this.

The double-blind study done on this issue showed that base levels of stress were significantly lowered by the supplement. It also showed that the subjects had a decreased level of cortisol [6].

Cortisol has long been associated with stress in individual humans. Reducing cortisol levels is one of the single healthiest things that you can do to promote not just your mental health, but your physical health as well.

It's a fact that mental health concerns like anxiety or general stress can affect the body as well, making it more difficult to operate at your peak level. It can also negatively affect your ability to work at a particular job.

Stress and anxiety are a natural part of just about everyone's day. They just happen due to the day to day concerns of jobs and life in general.

This means that any supplement you can take that might aid in reducing stress can reap huge benefits both to your physical and mental well-being.

How it Works

Arginine is involved with ridding the body of waste and also in the synthesizing of proteins [3].  This is why it's thought to have regenerative capabilities when involved in various body systems.


Recommended Arginine dosage is 5g before each work-out.
