L-Arginine and Erectile Dysfunction: Can It Work? Review


Natural treatments for erectile dysfunction are hard to trust at times because you don’t know what most of the ingredients are or what they do. Luckily, you have a starting point because there is one ingredient that you should always look for.

If you have done any research on Holding men, you have probably encountered a product or two that contains L-arginine, an amino acid that promotes the production of nitric oxide.

L-arginine has a myriad of health benefits, but it has primarily been found to be effective in the treatment of erectile dysfunction. It has been so publicized that many have been led to wonder if it could present a cheaper, safer alternative to more popular and pricey supplements like Viagra and Cialis.

How it Works

L-arginine functions in much the same way as sildenafil citrate, also known as Viagra. It enhances the action of nitric oxide, thereby relaxing the muscles surrounding blood vessels and supplying the penis with blood. When this occurs, blood vessels in the penis dilate, increasing blood flow, which may help a man maintain an erection as more blood rushes to the penis.

While both L-arginine and Viagra deal with nitric oxide as a treatment for erectile dysfunction, Viagra blocks the enzyme PDE5, which destroys nitric oxide, and L-arginine actually helps to produce nitric oxide. Another difference is that L-arginine is taken on a daily basis for erectile dysfunction, while Viagra is taken only when sexual intercourse is anticipated.

Is it Proven to Work for Erectile Dysfunction?

When you’re researching ingredients in male enhancement supplements, you want to be sure that each has professionally performed studies testifying to its usefulness. In the case of l-arginine, there are several.

The most convincing, perhaps, is a 1999 study published in the journal BJU International. During the study, 50 men with erectile dysfunction took either five grams of L-arginine or a placebo every day. After six weeks, more men in the L-arginine group showed improvement compared to those taking the placebo. Though it does work more slowly than other stimulating ingredients, it is worth trying if you are seeking male enhancement.

However, you should be sure to check your prospective supplement for dosage information. To be effective, L-arginine must be included is a dose of at least 5mg.

Are There Other Benefits?

Arginine also triggers the body to make protein and has been studied for bodybuilding and the enhancement of sperm production. It has also been linked to an increase in libido in both men and women.

And because it increases the capacity of blood vessels, it allows more blood and nutrients to flow to muscles. So, if you’re looking to bulk up a little, l-arginine in your male enhancement supplement could give you an extra boost.

Final Thoughts on L-Arginine

Since erectile dysfunction can be caused by a variety of factors, including aging, diabetes and other endocrine disorders, is it unreasonable to assume that L-Arginine will be effective in all cases.

However, it will be most effective in those men whose erectile dysfunction is a result of low levels of nitric oxide. Optimal nitric oxide production will ensure ideal erectile function, and for many people with sexual dysfunction, arginine-based supplements will ensure adequate nitric oxide levels.

    I’m 62 yrs. old, and up until about two years ago, have enjoyed a terrifically wonderful and active sex life with my wife of 15 years. We both were making up for “missed opportunities” from previous marriages. I’ve gained too much damned weight the last few years, and my testosterone level is way down. I know the consumption of L-Arginine won’t improve that, but I’m believing it’ll help me to “get it up” a little better, and keep it up, at least better than I’ve been doing the last year or so. Thanks for your ear. I’m going to try one of the better supplements. Nice web site. Keep up the good work.

      I’m 39 and been partially impenott for 15 years. I drank heavily for 4 of the past fridays not any other days. Last time I drank was 11 days ago. I couldn’t get erect 7 days after my last drink. Even though alcohol leaves the body after 3 days, I did get erect during the week. Do you think alcohol is the culprit of my current condition or is this mental? Is this just temporary and will I return to normal? Please let me know. Thanks.

        Larry, if your doctor recommended one product and it didn’t work, then ask him/her to recommend a different one. Sometimes it takes several attempts to find the right product to suit your individual needs. Due to your medical history, it’s best to turn to a doctor for advice in this matter.

    Guys dont wait any longer. I sent my husband to a male medical clinic specializing in ED. They have many different types of treatment. My hubby is on meds affecting his ability to maintain and keep a hard enough erection for sex. It really was terrible and frustrating for both of us. He was given this little needle to do self injections prior to intercours. He gets a erection in about 7 min. His penis is rock hard and his erection lasts a long time. He is 62 y/0. At the clinic there were so many men there with the same problem. I wish we didnt wait so long.

      I partly know how you feel. My husnbad is able to maintain an erection but its not much use when his drive is gone. For almost too years we didn’t have a good sex life at all. I’m alot younger than him and therefore want it alot more than he does. Now we’ve managed to overcome the problem to an extent, not completely but its got alot better. I don’t know what the cure will be for you. I do agree the sex toys could help to fulfill your needs and you should definately try them. But although I don’t have the answer, I do know that love conquers all and that it was our love for each other that has gotten us this far. So I don’t believe you too are going to split. Eventually I’m sure you will find an answer. You’ve both gotten this far and you’re working together on it. You’ll get there. It is unfair for both of you but I believe that there will always be some imperfection in a relationship. If it wasn’t a sex problem, it’d be a money problem or something else causing trouble in the relationship. I hope you do find the answer and I wish you two the best of luck. Also, I hope you will make some nice friends here. I’m Irish, from dublin and I have 3 lovely chinese friends and they are a blessing.Good luck, my friend ^^

          Alcohol can have a dramatic impact on your overall health, including your ability to have and maintain an erection. The longer you’re sober, the better off you’ll be. However, if you’re really concerned, ask your doctor for a few pointers.

    Hey guys, first and foremost look after your health. If you have no health you have nothing. If you look after your health, you will feel good, look good, enjoy life and also have sex which is part of a good life.
    Now I do take a lot vitamins but for sexual health I take , ie: Saw Palmetto caps. for prostrate health, Tribulus to help your testosterone levels up,Ginko for ciculation, last but not least L-Arginine 1000mg for nitic oxicde production and energy. Watch you alcohol, sugar and fat intake. I am a 75 year old male and get good erections and can ejaculate. If you are a master of all your health the benefits will be mountainous.

      Sounds like good all-around advice with the health part, Fred. As far as supplements, what would you spend per month approximately since I’m on a tight budget?
