L-Arginine, an amino acid, plays an important role in human biochemistry. This includes your normal immunity mechanism, secretion of hormones, and ammonia detoxification. L-Arginine also helps in nitric oxide formation, an important part of endothelial-derived relaxation factor.
The endothelium is the inside layer of the blood vessels and arginine supplements are used to make more nitric oxide. Thus, more nitric oxide formation results in relaxing and dilating the blood vessels.
Nitric oxide causes endothelium-dependent effects in the main cardiovascular system. There have been several opinions in support of the fact that amino acid acts wonders in matters of hypertension, intermittent claudication, preeclampsia and erectile dysfunction.
Amino acids have always been a subject of research in treating diabetes, interstitial cystitis, trauma, infertility in case of both men and women, burns, syndrome X and even helps athletes in performing well. Its positive effects for various medical conditions are to be established by research.
It is true that arginine supplements produce positive sex effects but still there is nothing to be too thrilled about it. Still more examinations and research works are left to certify arginine having magical sexual-healing powers. However, this particular medicine has a role to play in matters of dilation of blood vessels, just like Viagra or Sildenafil citrate.
Low dose of L arginine i.e. 500 mg at least 3 times a day proved ineffective for erectile dysfunction.
A study conducted with 50 men having erectile dysfunction problem were given 5 grams l arginine everyday for six weeks. This study was double-blind, placebo-controlled. One third of 50 men group displayed positive signs. This improvement was more than the improvement observed in placebo group that was 10%.
A study was done on a group of 40 men, aged 25-45 years, which had men with and without erectile dysfunction. This study proved that oral administration of L arginine along with Pycnogenol causes a more positive effect in treating the condition of erectile dysfunction.
Erectile functioning was observed to greatly improve after one month of combined medication of L arginine and Pycnogenol. There was 80% improvement in the condition of erectile dysfunction. This happened almost miraculously and that too with zero side effects.
L arginine gets converted to nitric oxide and this is the prime specialty of the supplement. Nitric oxide gets converted into a form of cGMP.
In this way cGMP plays the role of secondary messenger which initiates normal muscle relaxation causing dilation of blood vessels and this enables more blood enter the male genital organ resulting in erection.
However, metabolism of nitric oxide happens very fast and thus the positive effects of l arginine are immensely short lived. L arginine is a semi-essential amino acid which gets synthesized within the body from orthinine.
This form of amino acid potentially supports protein synthesis as it has great role to play in nitrogen storage and transportation. It is also essential to know that amino acid is well utilized for the production of creatine.
User comments on L Arginine
I had severe erection problems once I started the intake of proton pump inhibitors. And this was mainly for serious acid reflux. I did switch on to proton pump inhibitors with several negative side effects. It caused dryness of the eyes, flaring up of colitis and severe problems in matters of erectile functioning.
At times situation was too bad as it shrunk my penis and scrotum and I had a sensation similar to ice blocks and my penis was absolutely lifeless.
I was recommended the intake of Viagra which helped in normalizing my sexual sensation but was not completely effective. After several tests my doctor suggested a change of medication. Thus the acid reflux switched over to H2 blocker. This was helpful but no way completely successful.
For me sexual pleasure was like a dream and then I took the final decision of adopting herbal treatments and amino acid supplements. However, in this case L arginine is a bit different. It acts in promoting an overall sexual feel rather than solely treating a problem of erectile dysfunction.
It has been a few months now and I have indeed improved in matters of sexual intercourse by the regular intake of three x 500mg L-Arginine 3 times a day. Now, I do not need to have Viagra because l arginine has taught me what normal sex is all about. There has also been a remarkable augmentation in the level of orgasm ejaculation.
Thus I have indeed experienced immense benefit in having L arginine along with essential supplements of several multivitamin tablets. L arginine indeed works by making love making pleasurable.
