Two Supplements for Erectile Dysfunction

Erectile dysfunction (ED) is a very common disease affecting millions of individuals worldwide, which is defined as the inability to achieve or maintain an erection sufficient for a satisfactory sexual activity. The prevalence of this condition increases with age affecting the 52% of men aged between 40 and 70 years.

L-arginine with pycnogenol

Pycnogenol (PYC), rich of many phytochemicals of medical value, is a nutrient supplement extracted from the bark of European coastal pine. The extract has been widely studied for the past 40 years, with more than 160 clinical trials and 450 scientific publicationsensuring safety and efficacy as an ingredient.

L-arginine is an amino acid that helps the body build protein. Your body usually makes all the L-arginine it needs. L-arginine is also found in most protein-rich foods, including fish, red meat and poultry.

L-arginine acts as a vasodilator, opening blood vessels, making it a useful supplement to help heart conditions and erectile dysfunction.

The following information is from Life Extension.

If sexual satisfaction is your goal taking both L-arginine and pycnogenol together “supports male blood flow, sperm quality and satisfaction during intercourse.

  • L- arginine and pycnogenol complement each other because together they can provide a greater release of nitric oxide, which provides support for vascular health and sexual health in men.
  • Pycnogenol acts on an enzyme called endothelial nitric oxide synthase (eNOS), which converts L-arginine into nitric oxide in the endothelium. (Nitric oxide dilates blood vessels; this is an endothelium-dependent function that allows for greater blood flow.)

How do these two nutrients help support healthy sperm levels and sperm quality?

If you guessed the enhancement of nitric oxide production you’d be partially correct, but it’s also because this pairing does a good job fighting free radicals which could have an impact on sperm.


Pycnogenol is available as capsules and is usually given at a dosage of 100 to 200 mg daily, split into two or three doses (e.g., 100 mg one to two times daily, 50 mg two to three times daily). Taking pycnogenol with food may reduce gastrointestinal side effects. [source]
