L-Arginine Benefits for Men with ED: Dosage and Effects

L-Arginine: Natural Blood Flow Booster This is a review of L-Arginine that focuses on its benefits for sexual enhancement in men.

What is L-Arginine?

L-Arginine is an amino acid that is found in some foods, including red meat, white meat (chicken, fish, etc.) and dairy products. It is also produced in the body, and can be synthesized in the laboratory.

What Are the Benefits of L-Arginine?

L-Arginine is converted in the body into nitric oxide (NO), which causes blood vessels to expand and thus it increases blood flow. It is taken as a dietary supplement for different purposes, including:

  • Improving erectile function in men with ED.
  • Increasing sperm count and motility.
  • Improving heart health and circulation.
  • Reducing blood pressure.
  • Reducing leg pain that results from poor circulation.
  • Improving healing and recovery, especially after surgery.

L-Arginine for Erectile Dysfunction

L-Arginine is one of the most used alternative remedies for erectile dysfunction. Because it increases the levels of nitric oxide (NO) in the blood, L-Arginine is a potent vasodilator that generates a similar effect to PDE5 inhibitor drugs, like Viagra and Cialis. However, since L-Arginine is way less effective than prescription chemicals, one must consume large quantities of it to notice improvement in penile blood flow and erection strength.

In some studies, daily doses of 6 grams, 8 grams, 10 grams, and up to 30 grams were used to treat men with erectile dysfunction. Results varied for each user, but it was indeed found to be a helpful supplement for erections.

There is one interesting study where they noticed that taking pine bark extract together with a relatively low dose of L-Arginine was many times more successful in improving ED than taking L-Arginine alone.

Whether you have erectile dysfunction or not, taking L-Arginine on a daily basis can have a long-lasting positive effect on circulation to your penis, which improves erection response time, hardness, and the ability to maintain an erection longer.

What Dosage of L-Arginine Should I Take?

There are different dosages used in dietary supplements, up to 30g for men with ED.

If you don’t have ED and just want to boost your erection, I recommend you start with a dosage of 1,200mg daily, which you can take in the morning.

If that is not effective, or if you have ED, you can increase the dosage gradually up to 9,000mg (9g) daily; 4,000mg in the morning and 5,000mg in the afternoon; or 3,000mg in the morning, 3,000mg in the afternoon, and 3,000mg in the evening — whichever works best for you.

Taking L-Arginine on an empty stomach (with a glass of water) delivers the best results. If you take it with a meal containing protein it can significantly reduce absorption, and thus effectiveness.

What Are the Side Effects of L-Arginine?

L-Arginine is generally safe and well-tolerated in adults with no noticeable side effects. Here are some safety notes:

  • L-Arginine lowers blood pressure, so if you take medications for high blood pressure together with L-Arginine it may cause your blood pressure to drop too low.
  • L-Arginine increases blood flow and may interact with nitrates or other medications that increase blood flow.
  • Avoid taking L-Arginine with Viagra or any other ED drug.
  • Consuming high doses (10g or more) may cause diarrhea.

Where to Buy L-Arginine?

You can find it at GNC, Walgreens, CVS, Walmart, and almost any local store that sells dietary supplements. Quality, dosage, and price vary from one brand to another.

One of the good online stores that sell L-Arginine for cheap prices is Absorb Health. You can order it online for $10.99 (100 capsules X 400mg). They ship worldwide, but refund policy is only valid for US customers.

Note: I strongly recommend that you take pine bark extract with L-Arginine as it has been clinically proven that combining these two supplements can significantly increase effectiveness. Pine bark extract is a powerful antioxidant and blood flow enhancer that you can buy from Absorb Health at a low price of $10.99 for a bottle of 100 capsules X 200mg.
