L-arginine, also called arginine, is an amino acid that helps increase nitric oxide production in the body, resulting in various health benefits.

When l citrulline and l arginine are taken together, you could see an increase in cardiovascular, immune boosting, and sexual health benefits.

Together, they:

  • Support cardiovascular health
  • Boost nitric oxide production
  • Help blood flow more easily
  • Support healthy blood pressure
  • Boost the immune system
  • Detoxify the liver
  • Eliminate ammonia from the body
  • Enhance recovery from intense workouts
  • Improve sexual stamina

Who Benefits?

By taking l-arginine and l-citrulline, those who benefit are:

  • People looking to support healthy blood pressure
  • Those who want to avoid angina
  • Anyone who wants to avoid poor blood circulation
  • People looking for protection from strokes and heart attacks
  • Athletes who want faster recovery after workouts
  • Men suffering from erectile dysfunction

How are L-arginine and L-citrulline Connected?

When citrulline enters the kidney:

  • It’s converted into arginine
  • Plasma and tissue levels of arginine increase
  • Increases nitric oxide production and relaxes blood vessels
  • Helps eliminate ammonia from the liver

Citrulline and Arginine are Essential

Citrulline and arginine are important in:

  • Vasodilation (widening of the blood vessels)
  • It’s a result of the relaxation of smooth muscle cells within the vessel walls
  • The inner lining of blood vessels uses nitric oxide
  • The nitric oxide signals the surrounding muscle to relax
  • The result is relaxed blood vessels and increased blood flow

Other benefits include:

  • Raised plasma and tissue levels of arginine
  • Enhanced nitric oxide production

What Inhibits Proper Nitric Oxide Production?

  • Atherosclerosis
  • Diabetes
  • Hypertension
  • Over-consumption of salt
  • Aging

L-arginine Supplements

Some of the benefits of taking l-arginine nutritional supplements include:

  • Assisting in nitric oxide production
  • Helping with conditions like atherosclerosis and intermittent claudication
  • Helping with other conditions that improve when blood vessels are relaxed
  • Supplemental citrulline boosting blood levels of arginine

Citrulline is more readily absorbed than arginine alone:

  • It bypasses metabolism in the liver and gastrointestinal tract
  • Is readily absorbed in the kidneys
