L-Arginine For ED: Should You Give It A Try?

Amino acids play a role in protein synthesis. While this is a known fact, there is more to these chemicals. L-arginine is essential for oxygen and nutrient delivery, as it helps blood vessels relax.  This amino acid may also help with ed symptoms. L-arginine for ED has become a popular topic. In this post, we explore this amino acid and consider if it may help.

What is L-Arginine?

The body makes some l-arginine on its own. You also get l-arginine through your diet. Once in your body, the amino acid is converted into a gaseous substance, known as nitric oxide. This gaseous molecule plays a critical role in the blood circulatory system.

Nitric oxide widens your blood vessels. This ensures blood can flow through properly. It can also help with some circulatory problems.

Eggs, Dairy and food like red meat hold low amounts of L-arginine. By consuming foods with l-arginine, you help your body replenish its reserves. You also increase nitric oxide content in your bloodstream.

In some cases, a person’s need for L-arginine exceeds the body’s capability to produce or consume naturally. If that is the case, l-arginine supplements can be considered. However, like with any supplement, you should be cautious when taking it.

Too much L-arginine is known to have severe side effects, in some cases death. Consult your physician before using the supplement as you should know how your body interacts with it. Some medications can interact with l-arginine supplements.

Taken at the right doses, l-arginine for ED could be a possibility. We'll explore the benefits in the next section.

Benefits of L-arginine

L-arginine helps the body build protein, and it is turned into nitric oxide. Those effects give L-arginine a wide variety of benefits.

One study found that nitric oxide may even play a role in male fertility. This further enhances the importance of l-arginine, as your body will turn this amino acid into nitric oxide.

L-arginine, and nitric oxide, plays a role in muscle growth too, especially when paired with resistance training.

There are many claims about L-arginine. Not all of those are backed up by scientific research.

Here is a small list of researched benefits of L-arginine, apart from its role in muscle growth and fertility:

  • Nitric oxide, produced from l-arginine, relaxes blood vessels. This helps to increase blood that goes into your penis during an erection. In turn, L-arginine may be a great natural option for men with ED symptoms. L-arginine supplements are sometimes combined with Tadalafil to provide a more significant improvement in erectile function and quality.
  • When blood vessel walls are relaxed, there may be a reduction in your blood pressure levels too. Your heart does not need to work so hard to pump blood through your body.
  • L-arginine may also be helpful for certain types of heart disease.

 L-arginine also has the ability to help with other complications. While further research is still needed, here are some additional benefits that may be offered:

  • The ability to treat burns
  • The enhancement of exercise performance
  • To heal wounds faster
  • To reduce anxiety

Considering the benefits, it should be clear why l-arginine for ED is something you may find as a recommendation. When using l-arginine for ED, your blood flow improves, and you might last longer. The increased blood flow means more oxygen can be delivered to your muscle tissue and cells. This is what ultimate contributes to better physical performance.

Side effects of L-arginine for ED

Whether considering L-arginine for ED or any other purpose, it is always important to consider potential side-effects. L-arginine can have bad side effects when taken as a supplement. The risk of side-effects is higher among people taking prescription drugs. There are also certain conditions that make l-arginine an inappropriate supplement. Some of the side effects are:

  • Abdominal pain
  • Diarrhea
  • Gout
  • Low blood pressure
  • Bloating

Who should not take L-arginine

L-arginine may have severe health risks for certain types of people:

  • Increased risk of death after a heart attack
  • Worsening herpes flares
  • Difficulty controlling blood pressure while doing a surgery
  • Adverse reaction with medication like Viagra and blood pressure medication has been noted
  • Severe illness or death in infants and smaller children

There are risks associated with L-arginine but there is a lot of studies that show smaller doses is safe to take. The side-effects, especially the more severe ones, are more likely to be found among people who take high doses of the supplement.

Is there another way to get L-arginine for ED?

There are other, more natural ways to get your healthy dose of L-arginine. Foods generally contain low doses of l-arginine, but every bit counts toward the daily goal. Remember that your body also makes some l-arginine.

Meat lovers can turn to animal proteins. This would include chicken and turkey. Dairy products are also a good source of l-arginine.  

People who do not eat meat also have options. Soybeans, pumpkin seeds, peanuts and lentils can give them a dose of L-arginine.


L-arginine helps to increase nitric oxide, a gas that runs through your bloodstream. This gas promotes the relaxation of blood vessels, allowing more blood to push through.

Among men with ED symptoms, nitric oxide may contribute to better blood flow to the penis. This means erections may be easier to obtain. Your erection could also be harder and last longer, as more blood is available in the right areas of your body. It is also important to look at additional factors that play a role in ED. Combining l-arginine for ED with the ability to talk openly about this problem, for example, could yield even better results.
