When you read most of our reviews, your probably wondering why so many products contain an ingredient called
L-Arginine. Of the 80 or so male enhancement products that we have official tested,
L-Arginine is by far one of the most popular substances found in these products. The substance is not only popular
in male enhancement therapy, but can also be found in several different pre workout formulas as well. But what
exactly is this stuff, and how does it work? We set out to learn everything there is about this substance, and try
to explain to you in non-technical/scientific terms how exactly it works to give you increased size.

1. What is L-Arginine?

Found in several of the foods we eat everyday, L-Arginine is an amino acid which has
several very interesting uses. Their are several unconfirmed benefits of L-Arginine, and proponents of the
substance will tell you anything and everything to get you to buy it. However, there have been several studies
concerning the use of L-Arginine for a number of conditions, including erectile dysfunction. L-Arginine is
most commonly found in:

• Fish
• Milk (Dairy Products)
• Beef
• Pork
• Chicken
• Seafood

You can also find L-Arginine supplements in a wide range of health food store chains, including GNC, Vitamin
Shoppe, even local grocery stores carry it. The prices for these supplements often range from the very cheap ($14
at Walmart) to the insanely expensive ($94 on Sears.com), but the basic formula is pretty much the same.

They are usually available in a variety of forms, including powder substances that you can mix with drinks, gel
caps, tablets, and capsules, and even in liquid form. There is generally no taste associated with this
substance.

2. So How Does L-Arginine Work For Male Enhancement?

Officially, there are several studies pertaining to the use of L-Arginine to help reduce symptoms of Erectile
Dysfunction. But unlike most pharmaceutical drugs, their has not been any conclusive studies that have proven
beyond a reasonable doubt that it will work for everyone. It is also not an approved therapy by the FDA, although
several other regulatory agencies in Europe have approved it’s use.

While L-Arginine can produce effects similar to many alternative ED supplements, it is best used when in
combination with all natural aphrodisiacs such as Yohimbe or Epimedium. In fact, there have been clinical studies
that have proven that the use of certain quantities of L-Arginine (around 2,000 mg), with yohimbe can work just as
well as normal erectile dysnfunction prescription medications.

But the real benefit behind the use of L-Arginine for male enhancement is a process called
Vasodilation. As demonstrated in the diagram below, vasodilation occurs when Nitric Oxide is produced in the body,
allowing for the blood vessels to dilate. During this process, the smooth muscle that surrounds the blood vessels
are relaxed, which causes the dilation. This results in increased blood flow, which is obviously beneficial for an
erection.

3. Does L-Arginine Work For Everyone?

Personally, every supplement that i have taken that contains L-Arginine has acted differently. Some have give me
an increase in energy and enhanced libido, such as Nitrocut, and others like
NitroPumpXL, have done absolutely nothing. From my experience, I don’t think
simply taking just L-Arginine can do much for male enhancement, but it is so much more effective when you are
using it in combination with natural aphrodisiacs.

I also read through several doctors who were quoted on other sites saying that they don’t see L-Arginine being a
effective therapy to treat erectile dysfunction. But let’s face it, most doctors have an agenda and incentive to
push pharmaceutical drugs on their patients, so of course they are going to say that.

If you are looking to gain size, you should also know that l-arginine will NOT give you a permanent
increase in size. I suggest that if you are going to buy a product that contains L-Arginine, you do so from a
reputable company that uses a quality version of the substance.

L Arginine and male enhancement side effects are very uncommon,
and happen to less that 2% of all men that we have talked to.  That being said, it is always prudent that you
speak with your doctor concerning the use of these substances.
