If you want to build your muscles, taking certain supplements will help you reach your goals. Learn about the effects of using L-arginine as a preworkout supplement.

L arginine Benefits

If you want to boost your nitric oxide levels, l-arginine is the perfect way to do it.

As an amino acid responsible for nitric oxide regulation, L-arginine increases your blood flow.

By improving your blood flow, you can experience bigger and better muscle pumps during workouts.

How Effective is L-arginine?

L-arginine is effective when it comes to improving your blood flow.

Unfortunately, it doesn’t have the best absorption rate when ingested orally (through foods or supplements).

If you combine it with another nonessential amino acid called glutamine, you can improve the absorption rate.

Pre Workout Benefits


There are a few studies that explore the effectiveness of L-arginine when it comes to improving blood flow and boosting nitric oxide levels.

Blood Flow

A 2009 study published in Medicine & Science in Sports & Exercise measured the effects arginine had on 18 participants while they focused on resistance exercise.

They found that supplementing with arginine during resistance exercise didn’t affect blood flow.

Nitric Oxide

In 2009, a study published in The Journal of Nutritional Biochemistry explored the effects arginine had on ten elite athletes when it came to raising nitric oxide levels.

After taking an arginine dosage of 6 g for three days, the participants were told to perform intense exercise.

The study concluded that “the results of this study suggested that short-term arginine supplementation had no effect on nitric oxide production.”

Pre Workout Side Effects

One of the many positive things about L-arginine is that it doesn’t come with many side effects.

If you take more L-arginine then suggested, you may experience side effects such as diarrhea, abdominal pain, and bloating.

Generally, side effects are rare and minimal when they do occur. If you stay within the recommended dosage, you should be fine.


While l-arginine supplementation may not be the best way to enhance your workout performance, it’s still an excellent supplement for your overall health.

It’s absorption rates during intense workouts may be negligible, but it plays a significant role when it comes to circulation.

It is proven that increasing the amount of l-arginine in your system results in better blood flow and higher nitric oxide levels.
