2024's Top 9 L-Citrulline Supplements

Find out what to look for in a quality L-Citrulline supplement and what to watch out for

What is L-Citrulline?

Citrulline is a nonessential amino acid, meaning your body can produce it naturally. However, you can increase citrulline levels by eating foods containing citrulline or by taking an L-citrulline supplement.

After consumption, your body transforms L-citrulline into another type of amino acid, L-arginine. Strangely, supplementing with L-citrulline has been shown to raise L-arginine levels more effectively than taking L-arginine itself.

What Does L-Citrulline Do?

After it is changed to L-arginine, its primary ability is to improve blood flow. By creating nitric oxide, it is able to dilate the blood vessels, creating wider pathways for blood to flow. As you can imagine, this results in benefits to the entire body.

Benefits of L-Citrulline

✔️ Promotes Cardiovascular Health

✔️ Improves Exercise Performance

✔️ Combats Fatigue

✔️ Increases Levels of Growth Hormone

Research

Some research suggests that L-citrulline’s ability to improve blood flow may be able to decrease symptoms of mild ED and improve the ability to maintain an erection.

A Note About Consistency

L-citrulline is not a one and done supplement. Research shows that most of the benefits only appear after a minimum of 7 days supplementation.

Natural Sources of L-Citrulline

L-citrulline is difficult to get in high amounts from natural sources, but here is a short list of foods which can provide some amount of this powerful amino acid.

✔️ Watermelon

✔️ Cucumber

✔️ Pumpkins

✔️ Bitter Melon
