L Arginine benefit, impotence, erectile dysfunction – L Arginine Information
L Arginine Tablets and Powder for better erectile function
January 2 2017
L-Arginine is an amino acid that has a benefit in numerous areas of human biochemistry, including ammonia detoxification, hormone secretion, and the immune system. L Arginine is also of benefit as a precursor to nitric oxide, a key component of endothelial-derived relaxing factor. The endothelium is the lining inside blood vessels and l arginine supplements help make more nitric oxide. Therefore, l arginine, by making more nitric oxide, helps to relax and dilate blood vessels.
Heart and blood vessel benefit
Nitric oxide is a messenger molecule involved in a variety of endothelium-dependent effects in the cardiovascular system. Because of the benefit of l arginine with nitric oxide production, it may potentially be useful in hypertension, preeclampsia, intermittent claudication, and erectile dysfunction. However there are more potent herbs that work better in treating erectile dysfunction naturally as you can find out by reading the article.
Impotence, erectile dysfunction, improving erections
As to l arginine and erectile function, see below. If you have an interest in l arginine as a sexual enhancer, consider Passion Rx with Yohimbe instead which is very effective. Passion Rx does not have l arginine amino acid. This multi-herb aphrodisiac formula is an excellent option for treating low libido in men and women. It can be combined the same day as an arginine supplement.
More research needed
Even though l arginine has been claimed to be useful for some of the conditions listed above, it would be premature to be overly excited. Much research needs to be done before we can be more confident about l arginine benefit potential. However, so far, l arginine appears to have a role to play in conditions involving blood vessel dilation. Whether the dilation is short lived or continues for an adequate period is still being evaluated. L Arginine does not appear to be helpful as a supplement taken by those who have suffered a heart attack. The limiting factor in the benefit of arginine as a supplement is that the conversion to nitric oxide may be short lived.

L Arginine is a semi-essential amino acid synthesized by the body from ornithine. Arginine supports protein synthesis as it is involved in the transport and storage of nitrogen. Among many functions, L Arginine is used by the body to produce creatine. Each arginine supplement tablet contains 750 mg elemental L Arginine.
Usage: Take 1 to 6 arginine supplement tablets daily, or as directed by your qualified health consultant.

L Arginine benefit for Erectile Dysfunction?
One of the more popular supplements found in sexual enhancement products is L-arginine. What makes l-arginine interesting is that it can be metabolized to nitric oxide (NO). NO is the most powerful chemical known to dilate and engorge blood vessels in the penis and clitoris. What does the research say about the role of arginine in erectile dysfunction?
A Low dose of l arginine supplement, at 500 mg three times a day, has not been found to benefit impotence.
A double-blind, placebo-controlled study of 50 men with erectile dysfunction tested l arginine at a dose of 5 grams per day for six weeks. About a third of the participants who received l arginine showed benefit, and that improvement was greater than the 10% improvement seen in the placebo group.
The amino acid L Arginine has been studied in combination with other nutrients as a treatment for sexual dysfunction in women. A small trial found some benefit with a combination treatment providing a daily dose of 2,500 mg of l arginine, as well as ginseng, Ginkgo, and Damiana. In a four-week, double-blind study, 77 women with decreased libido were given either the combination product or a placebo. Those taking the l-arginine blend showed statistically greater benefit, reporting increased sexual desire in 71% of participants given the treatment. In the placebo group, 42% reported an increased libido.
A study done at the University of Texas at Austin examined l arginine benefit, combined with yohimbine, on sexual arousal in postmenopausal women. Twenty-four women participated in three sessions in which sexual responses to erotic stimuli were measured following treatment with either l-arginine glutamate (6 g) plus yohimbine (6 mg), yohimbine alone (6 mg), or a placebo, using a randomized, double-blind design. Sexual responses were measured at one hour after taking the supplements. Compared to placebo, the combined oral administration of l-arginine and yohimbine increased vaginal pulse amplitude responses to the erotic film. It is well known that yohimbine, alone, has a significant benefit on sexuality and whether l-arginine is not clear.
Arginine Benefit for Sexual Enhancement
There are many potent herbs that have sexual enhancement properties. L-Arginine is not on our top ten list of aphrodisiac supplements. We prefer the combination of herbs found in Passion Rx.
Mechanism of Action of the amino acid L arginine
The most likely explanation for the mild benefit of l arginine is its conversion into nitric oxide. Nitric oxide is converted into cGMP, which becomes the secondary messenger that causes smooth muscle relaxation, resulting in more blood going into the genital organs, which leads to erections. However, nitric oxide is quickly metabolized and any potential l arginine benefit could be short lived.
L Arginine benefit
There is some supporting evidence that l arginine benefits by reducing angina and lowering blood pressure. Research indicates supplemental l-arginine reduces pulmonary resistance and blood pressure. L-Arginine supplementation beenfits renal function in patients with chronic heart failure. Oral L-arginine benefits endothelial function in older healthy individuals. However, we are not convinced yet that l-arginine is a worthwhile supplement for erectile function or sexual enhancement, at least in low dosages.
L-Arginine benefit for Heart Failure
L-arginine supplementation may benefit the physical fitness of heart failure patients by enhancing their endurance to exercise.
NAC and L arginine benefit for high blood pressure
Long-term N-acetylcysteine and L-arginine administration reduces endothelial activation and systolic blood pressure in hypertensive patients with type 2 diabetes.

We tested the effects of l-arginine and N-acetylcysteine (NAC) administration in increasing NO bioavailability by reducing free radical formation. A double-blind study was performed on 24 male patients with type 2 diabetes and hypertension divided into two groups of 12 patients that randomly received either an oral supplementation of placebo or NAC + arginine for 6 months. NAC + arginine treatment caused a reduction of both systolic and diastolic mean arterial blood pressure, total cholesterol, LDL cholesterol, oxidized LD, high-sensitive C-reactive protein, intracellular adhesion molecule, vascular cell adhesion molecule, nitrotyrosine, fibrinogen, and plasminogen activator inhibitor-1, and an improvement of the intima-media thickness during endothelial postischemic vasodilation. HDL cholesterol increased. NAC + arginine administration seems to be of benefit and well-tolerated antiatherogenic therapy because it improves endothelial function in hypertensive patients with type 2 diabetes by improving NO bioavailability via reduction of oxidative stress and increase of NO production.
L Arginine Benefit Research update
Effect of oral L arginine on blood pressure and symptoms and endothelial function in patients with systemic hypertension, positive exercise tests, and normal coronary arteries.
Am J Cardiol. 2004.
Thirteen hypertensive patients with microvascular angina were studied before and after receiving oral L-arginine (4 weeks, 2 g, 3 times daily). L-arginine was of benefit in angina class, systolic blood pressure at rest, and quality of life. Maximal forearm blood flow, plasma L-arginine, L-arginine : asymmetric dimethyl arginine ratio, and cyclic guanylate monophosphate increased significantly after treatment. In medically treated hypertensive patients with micro-vascular angina, oral L-arginine may provide some benefit.
Arginine benefit emails
Q. Does l arginine benefit improve when taken as powder versus a capsule?
A. It depends on how much you plan to take. If your dose is 1 to 5 g, the capsule works. If you plan to take more than 5 grams of arginine, then the powder is more efficient.
Q. What are some foods high in arginine?
A. All foods that have protein contain arginine.
Q. Is l-arginine of benefit for a woman?
A. We can’t think of a medical reason where a woman needs l-arginine for a medical reason. L arginine is not a vitamin but an amino acid.
Q. Do you think l-arginine is of benefit in body building?
A. We’re much more impressed with creatine and protein powders than l-arginine for body building.
