2021's 10 Best L-Arginine + L-Citrulline

Best L-Arginine + L-Citrulline

Amino acids provide the building blocks for each cell, tissue, muscle, hormones and enzyme in the body. L-arginine and L-citrulline are two such amino acids – with a uniquely close relationship. L-citrulline converts to L-arginine in the body and vice versa.

D-Aspartic acid is primarily marketed as a training enhancement supplement that can boost male testosterone levels. Let’s take a look at some of these potential benefits.

What is L-Arginine?

L-arginine – or arginine – is a conditionally essential amino acid that can be made in the body from other amino acids. However, the body’s demand for arginine increases during intense exercise, stress and injury. For optimal levels, you must consume it from meat, fish, dairy products, dark chocolate and nuts – or via a dietary supplement.

What is L-Citrulline?

L-citrulline is an amino acid that’s found in meat, watermelon, pumpkin, legumes and nuts. Some citrulline is synthesized in the body, but it’s still important to consume this amino acid via diet or supplementation for optimal health. .

L-Arginine + L-Citrulline Health Benefits

These two amino acids are commonly seen together in exercise supplements as they work synergistically to boost the production of nitric oxide (NO) in the body. Together, they pack a real health punch when it comes to exercise performance, muscle recovery and heart health.

Boosts Exercise Performance

Taken together, L-arginine and L-citrulline help you last longer in the gym. Whether you’re doing aerobic or resistance exercise, you’ll get the most out of your workout and boost your “gains.”

These two amino acids are precursors to nitric oxide, a gas that relaxes the elastic blood vessel walls and allows them to expand and boost circulation. This ensures nutrients and oxygen reach muscles efficiently, improving exercise performance. Additionally, citrulline has been shown to assist with the production of adenosine triphosphate (ATP), energy molecules needed in large amounts during exercise.

A 2015 study found that taking 8g of citrulline before performing multiple-set resistance exercises increased the number of repetitions performed.

Another 2019 study on male athletes looked at a combination of 1.2g of both citrulline and arginine when taken 1-hour before an intense 10-minute cycling performance. It found that:

  • Blood concentrations of NO increased
  • Power output was significantly greater
  • There was a subjective increase in “ease of pedaling”

Supports Heart Health

Using arginine and citrulline together offers major benefits to heart health.

It’s largely due to the positive impact on NO synthesis and bioavailability, which promotes blood vessel dilation and healthy circulation. This reduces risk factors for cardiovascular disease like blood clots, arterial stiffness and high blood pressure.

Enhances Male Sexual Performance

L-arginine and L-citrulline may offer a natural treatment for men with erectile dysfunction (ED). By encouraging nitric oxide production and vasodilation, arginine and citrulline increase blood flow to the penis and support healthy sexual function.

Interestingly, research has found men with ED commonly have low levels of both these amino acids.
