L-Arginine is an amino acid that is a precursor, or building block, for many other bodily chenicals and functions. The theory is that if one increases the building block material, more of the functional chemical will be produced. There are many potental uses for L-Arginine: L-arginine is the body's chief source for creating Nitric Oxide. Since Nitric Oxide is the chemical that allows the male to have an erection, L-Arginine supplementation is used to treat erectile dysfucntion. Some researchers claim that L-Arginine is as effective as Viagra in some individuals. Another sexual side effect is that L-Arginine may increase sperm count and increase sperm movement. Some studies suggest that L-Arginine may help to decrease blood pressure. In summary, L-arginine shows promise in the treatment and prevention of cardiovascular disease, in the treatment of some forms of male infertility and some kidney disorders and it is helpful in accelerating wound healing in some circumstances. It has demonstrated some positive immune-modulating and anticancer effects. There is preliminary evidence that it could be helpful in some men with erectile dysfunction and in some others with migraine, liver disease and primary ciliary dyskinesia. Dosage: L-arginine is available in tablet, capsule, and powder form and as L-arginine hydrochloride and free base L-arginine. It is also available in medical foods as an aid in the enhancement of immune function. Various doses are used depending on what one is trying to treat. For cardiovascular health reasons, doses from 8 to 21 grams daily have been used in divided doses. To help aid with sperm quantity and quality, doses of 10 to 20 grams daily have been used in divided doses. Doses of 5-8 grams daily have been used for erectile dysfunction. Doses of 1.5 to 2.4 grams daily have been used for interstitial cystitis (kidney func). Since the doses are quite high, it is best to purchase a large bottle of L-Arginine, such as 1 gram per capsules.

Basically the tablet starts to fall apart after a couple of days and by 5 days it turns to powder and sheets of paper coating... Pretty useless if you like to sort out your vitamins into daily pill packs..

This pill is way to large to swallow, I am having to grind them up and mixing them with water to be able to take them.

Do a little research and you will find out that L-Arginine can cause cold sores. At this very high dosage (1000mg), it was not long before this happened to me. Also, I noticed nothing positive from this supplement.

These tablets are very delicate. They break apart in the bottle and you get a lot of powder mixed in with the remaining tablets. It's a mess. I'll try another brand.

Felt no change at all. Other Arginine products do much better than this brand. I have noticed the NOW brand disapointing me time and time again. I think this is it for me.
