despite the positive results derived from small case-control studies, which have demonstrated that in the presence of these particular risk factors l-arginine may improve endothelial function, it is still unclear whether chronic administration of l-arginine has the potential to prevent the development of coronary atherosclerosis in high risk subjects. Furthermore, in conditions such as diabetes mellitus, the effect of l-arginine on endothelial function is rather weak, possibly because of the greater extent of eNOS ‘uncoupling’ in diabetic vessels. Therefore, before l-arginine is supplemented at a clinical level, it is important to determine, in detail, those clinical conditions which are accompanied by l-arginine deficiency.

finally found a paper studying the effect of arginine on HSV until I read that. I also find it interesting that a number of places online (all selling lysine) say that lysine inhibits HSV and that arginine promotes the reproduction of HSV-1. But this paper says just the opposite: that arginine inhibits the reproduction of HSV-1.

pre-workout powder such as BSN N.O Xplode which was the product that started the entire trend of Nitric Oxide supplements.These powders usually contain some advanced form of Arginine (Arginine AKG),a few other aminos that work in syergy with Arginine such as Orthinine & Citrulline and some type of stimulant,usually Caffeine.

Not sure which name you are referring to, but "arginine" is not an IUPAC name. The IUPAC name is definitely listed under "other names." IUPAC names list each functional group and their position in the molecule, but "arginine" is a much simpler, commonly used name (which is why it is called a common

The first section of this page concludes with the line: "In general, most people do not need to take arginine supplements because the body usually produces enough." I am not sure if I follow this logic here, as, in general, most people do not need to supplement their intake of any amino acid. Should

I'm taking L-arginine and it's a miracle supplement. I've sufferered from severe bloating and stomach pain for years and this helps that alot and gives me a lot of energy. Maybe it helps b/c it helps improve blood flow to my stomach and liver. It's worked miracles for me and I will keep taking it.

Hi, very simple answer: You don't put anything into your condom. No instruction of use would ever recommend this. If you have blood-flow issues, refer to your normal doc and just say you want "more". There is a very good variety of ready and cheap substances available for helping your sex life. KR

Healthy adults can synthesize arginine to meet needs, but children cannot, and so need to also be consuming arginine. The Knowledge (XXG) article Essential Amino Acid clarifies the distinctions among essential amino acids, conditionally essential amino acids and non-essential amino acids.

It appears that the pKa values in the arginine article might be in the wrong order. PubChem (Arginine, C6H14N4O2 - PubChem) lists arginine pKa values as pK1 = 2.18, pK2 = 9.09, and pK3 = 13.2.
