L-Arginine Supplements

L-Arginine is a vital amino acid that plays a role in a number of physiological functions in the body, but is best known for its cardiovascular benefits. In the body, L-Arginine is converted to nitric oxide, which relaxes the blood vessels and regulates blood vessel tone and flexibility.

L-Arginine Benefits

Arginine, which is also known as L-Arginine, has various functions in the human body that include:
  • maintaining healthy immune system
  • improved circulation
  • helps to relax blood vessels, thereby lowering blood pressure
  • reduced stress on heart
  • proper wound healing
  • helping kidneys eliminate waste products


L-Arginine

L-Arginine, an important amino acid has numerous physiological functions but as mentioned, the most important is what it does for the heart. By converting to nitric oxide, L-Arginine relaxes the blood vessels which helps keep blood pressure under control and improve circulation. This also helps to improve their flexibility and tone.


L-Arginine is a natural dietary supplement that may also improve blood flow to the heart which can reduce clogged arteries and decrease angina (chest pain).

Since L-Arginine can relax arteries and improve the flow of blood, some researchers postulate that it may also be beneficial for individuals with ED, or erectile dysfunction.

Is L-Arginine Safe?

Clinical trials has shown that L-Arginine is safe and only had some minor side effects such as diarrhea, gout and bloating. It may also make breathing more difficult for those with asthma. L-Arginine may also react with various heart medications or other drugs like Viagra. Because of this, you should speak to your doctor about taking L-Arginine if you are on heart medication or take a medication for erectile dysfunction.
