Can L-Arginine & Pycnogenol (Pine Bark Extract) Really Treat ED?

Are you looking for a cheap and natural alternative to the little blue pill? You are probably tired of the countless offers for this and that ‘best herbal Viagra’. Most of those pills are no more helpful than any multivitamin, and rank nowhere next to prescription ED drugs. But there is one concoction that may actually be effective enough to qualify as a natural alternative to Viagra and other ED drugs.

The combination of L-arginine and Pycnogenol (pine bark extract) is a worthy consideration for any man looking to boost his circulation and energy naturally.

What is L-Arginine?

L-arginine is an amino acid that is obtained from protein-rich foods, particularly meats and dairy products. It is also produced in labs and used as natural medicine.

Once L-arginine enters the blood stream it gets converted to nitric oxide, which causes dilation of blood vessels and thus increases blood flow. It has an effect similar to Viagra’s and it has been clinically proven to improve erections in men with erectile dysfunction.

L-arginine is used for several health conditions, including erectile dysfunction, high blood pressure, congestive heart failure, and chest pain (angina). Many bodybuilders also take L-arginine to increase strength and performance during workout.

What is Pycnogenol?

Pycnogenol is a brane name supplement that is made from the bark extract of the French maritime pine tree (pinus pinaster).

The active ingredients in the pine bark extract are flavonoids called procyanidins, belonging to a class of flavonoids called proanthocyanidins or condensed tannins. Procyanidins have a powerful antioxidant effect in the body, and they also improve blood flow.

People take Pycnogenol and other brands of pine bark extract for different conditions, including circulation problems, sexual dysfunction, diabetes, asthma, leg and joint pain.

The Magic Combo

Both L-arginine and pine bark extract are used in male enhancement supplements, with varying results from one user to another. When used separately, they seem to have a limited and often insignificant effect on erections. However, when taken together, you can notice and feel a boost in your penile circulation and erection size.

A clinical study (link) found that daily supplementation of 1.7g (1,700mg) L-arginine had a success rate of only 5% after one month of treatment. However, when L-arginine was taken with pine bark extract (Pycnogenol), the success rate dramatically jumped to 80% after the second month of treatment, and 92.5% after the third month.

Results to Expect

The main effect of L-arginine and pine bark extract is an improvement in blood flow. Your overall circulation will increase and you will be able to notice the difference during sexual activity. You can expect these results:

  • Improved erectile function/response.
  • Harder and fuller erection.
  • A boost in energy and stamina.

Keep in mind that results vary for each user depending on the severity of the problem and its cause(s). But since these supplements are quite safe, affordable and available over the counter, they are well worth trying before looking at prescription drugs.

Dosage and Usage Instructions

  • L-arginine is normally consumed in daily doses ranging from 1,000mg and up to 10,000mg.
  • The normal pine bark extract dosage is between 50mg and 300mg.
  • I suggest you start with a dosage of 1,000mg L-arginine and 200mg pine bark extract once a day (in the morning or afternoon). If you notice no difference after a few days, increase the L-arginine dosage gradually up to 10,000mg daily.
  • You should take both servings together for best results. L-arginine works better on an empty stomach, but you can also take it with a protein-free meal. Protein meals can reduce absorption of the L-arginine supplement thus making it less effective.
  • Taking this combo on a daily basis can provide long-term enhancement of sexual function and circulation. You can also take it as needed; 1 hour before sexual activity.

Time to Action

You should typically feel the results after about 1 hour of taking the dose. It can last from few to several hours.


Both L-arginine and pine bark extract are generally safe for daily consumption. Normally, no side effects should be experienced.

Your blood pressure will decrease, so if you already take blood pressure or heart medications, your BP may drop very low. It is advised to talk to your doctor first if you have heart or blood conditions.

L-arginine may cause diarrhea, but mostly when a high dosage is used (more than 10,000mg).

Where to Buy?

You can find many brand and generic supplements of L-arginine and Pycnogenol at CVS, GNC, Walgreens, Amazon, and almost any drug store.

The price of L-arginine varies depending on the brand, quantity and quality. Generally, price ranges from $10 to $30 per bottle.

Pycnogenol is more expensive as it is a trademarked compound. Prices range from $30 to $60 per bottle. If you want a cheap alternative you can look for generic pine bark extract supplements as this is the only active ingredient in Pycnogenol. You can get a higher dosage at a lower price.

I’d recommend buying from Absorb Health. They have many good products at low prices, see links below:
