There are many natural ways to improve your circulation – and l-arginine is one of them. Learn about l-arginine benefits and your circulation.

L-arginine provides a variety of benefits, including better circulation. It is an amino acid whose main function is to help the body in protein production.

There are certain foods that are rich in l-arginine such as meat, fish, poultry, dairy products, nuts, and other plant and animal proteins. Moreover, you can find l-arginine in dietary supplement form as powders or capsules.

The amino acid also works to stimulate the release of insulin and remove ammonia from the body. Most importantly, though, is its ability to increase nitric oxide production in the body.

Nitric oxide is a compound that works to relax blood vessels, resulting in better circulation. The following are some of the circulation and heart health benefits you may experience from l-arginine.

L-arginine Benefits

There are a variety of heart benefits associated with l-arginine and it may help improve certain conditions. For example, it may help with angina, hypertension, cramping, intermittent claudication, and erectile dysfunction.

Some people use l-arginine supplements to boost workouts, the immune system, promote weight loss, and shorten recovery time. Additionally, some evidence suggests that l-arginine may help with preeclampsia and interstitial cystitis.

Erectile Dysfunction (ED)

According to certain studies, l-arginine supplementation may help men who experience erectile dysfunction. It may help since the amino acid increases nitric oxide production and relaxes the muscles surrounding the blood vessels.

In a 2017 study in Andrology, researchers found that men with ED had lower levels of l-arginine and l-citrulline than those without ED.

L-arginine Benefits and Your CirculationHeart Disease

Some studies suggest that l-arginine may be helpful in promoting heart health. Part of this is due to its ability to improve circulation, which leads to lower blood pressure levels.

Furthermore, high blood pressure (or hypertension) is one of the leading factors in heart attacks. By lowering blood pressure levels and maintaining them at a healthy range, overall heart health can improve.


According to some studies, combining l-arginine with nucleotides and omega-3 fatty acid may provide additional benefits. For example, it may help protect against infection, reduce recovery time, and promote healing after surgery.

Using L-arginine Supplements

The body naturally makes l-arginine, but certain factors such as age, medical conditions, and genetics may impact the body’s ability to produce it. Using supplements is a great way to make up any deficits you may experience or receive an extra boost.

L-arginine supplements are available in various forms including creams, capsules, powders, and even as IV in clinical settings. While some l-arginine supplements are named as such, other supplements may not even if they use l-arginine as a key ingredient in their formula.

For example, Circulation Boost contains 5,110 mg of l-arginine as a way to increase nitric oxide production and improve circulation. It also contains 1,010 mg of l-citrulline (another helpful amino acid) as well as other key vitamins and minerals.

Circulation Boost combines these ingredients to help promote heart health, energy levels, and blood pressure levels. Furthermore, it is available in an easy to mix powder form with a berry flavor that makes it easy to drink daily.

The Outlook

Various studies explore the benefits and effects of l-arginine on circulation and more. While some benefits need more research to make the claims conclusive, others are more widely accepted.

L-arginine is beneficial when it comes to improving circulation as well as promoting overall health in other ways. Consider adding l-arginine rich foods to your diet or taking supplements like Circulation Boost to improve your blood flow.
