No Change

Posted by Reviewer2022704 on Oct 08, 2012

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.

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.

Good Cheap Solution but tablets fall apart once taken out of container.

Posted by bodybuilder on Jul 20, 2012

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..

Bad quality

Posted by Reviewer1252766 on Jul 15, 2012

The tablets stored in the closed bottled simply burst one by one. It's still over a year before expiry date.

Posted by Reviewer3352270 on May 13, 2012

a soft disagreement (but not only with this product) : in other ingredients list, i allergize with one... so next time, i choose pure powder. Never mind, i prefer iHerb :)
