L-arginine benefits for men include improved sexual performance, fertility, athletic performance and better circulatory health.
L-arginine is a semi-essential amino acid that is needed to synthesize nitric oxide.
While your body can synthesize it internally in most cases, there are instances where it becomes necessary to supplement. Furthermore, taking higher doses of this compound can improve health in some key ways for both men and women.
This compound can stimulate the release of insulin and growth hormone, putting the body into an anabolic state where it burns more fat and builds more muscle.
Men also take L-Arginine to naturally boost libido, improve sexual stamina and make it easier to achieve an erection. It has been proven to improve sexual function and reduce instances of erectile dysfunction in both young and old men.
There is significant research into the effects of this amino acid for reducing the risk of heart disease, stroke, cognitive decline and headaches.

L-arginine is needed for the body to synthesize nitric oxide.
Power lifters, bodybuilders and other strength-based athletes often use nitric oxide boosters because it is known as a powerful vasodilator.
Vasodilation is the process of relaxing the endothelium which lines the inside of blood vessels.
When the inner linings of the blood vessels are relaxed, they increase in diameter and are able to deliver more blood throughout the body. This happens without causing an increase in intravenous blood pressure
Increasing circulation may not seem like a powerful therapeutic target, but it can actually result in profound benefits throughout the body.
Taking L-arginine means an increased delivery of oxygen, nutrients, hormones and other beneficial substances throughout the circulatory system.
With more blood and nutrients delivered to the muscles, performance improves during exercise. This can allow for increased exertion in workouts and enable both male and female bodybuilders to lift more for longer periods of time.
It can also improve the repair process following a work-out. Theoretically, muscles will recover from strenuous workouts faster which facilitates faster muscle growth.
There has not yet been sufficient research showing that L-arginine supplementation does directly accommodate increases in muscle size, power and endurance.
But research does show some enhanced athletic performance as well as improved wound healing and shorter recovery times following injury, surgery or illness.
L-arginine for Male Sexual Libido & ED
Because of L-arginine’s role in nitric oxide synthesis, it is widely used as a treatment for erectile dysfunction.
By increasing circulation, this increases the amount of blood being delivered to the genitals.
This can make it easier to attain an erection as well as boosting the libido.
In one study, taking 5 grams daily of L-arginine capsules for six weeks resulted in an improvement in sexual function among men with organic erectile dysfunction.
L-arginine is also believed to be an aphrodisiac for both men and women. Increased libido is one possible result of L-arginine supplementation, especially if it is combined with known sexual enhancers like yohimbe root.
L-arginine is also important for spermatogenesis (production of sperm) in men. It has been used to boost male fertility as well.
Additional L-arginine Benefits
L-arginine is a conditionally essential amino acid. It is needed for the synthesis of messenger ribonucleic acid (mRNA) as well as for protein synthesis. It is also needed to maintain a healthy immune system, and to help the kidneys and liver expel toxic substances like ammonia.
L-arginine is also used to reduce the risk of the following medical conditions:
- Angina, coronary artery disease and peripheral artery disease;
- Atherosclerosis and heart failure;
- Intermittent vascular disease and intermittent claudication;
- Vascular (migraine) headaches;
- Type II diabetes mellitus;
- Muscular wasting (common in post-surgery patients and HIV patients);
Safety of L-Arginine Supplements
There are certain health conditions and drugs that are not recommended to be combined with L-arginine supplements. L-arginine may cause complications in all the following cases:
- Those with cancer, cardiovascular disease, liver disease and/or kidney disorders;
- Those taking prescription antihypertensive drugs;
- Those taking nitrate drugs to increase inner-heart blood flow;
- Those who are pregnant or nursing babies;
Further, L-arginine should not be used by men taking sexual performance-enhancing medications like viagra. This can lead to serious complications.
All potential L-arginine benefits for men should be discussed with a doctor before starting to take this supplement.
