.. and what about L-argine? It is quite commonly used by athletes and men with erection problems use it. It helps with Nitric oxide production in veins and there are many studies about it.. mostly with lab-rats, like this:
http://www.ncbi.nlm.nih.gov/pubmed/12614590 "L-arginine and free radical scavengers increase cerebral blood flow and brain tissue nitric oxide concentrations after controlled cortical impact injury in rats"
--> These studies support the theory that L-arginine administration improves post-traumatic cerebral blood flow by increasing NO production
PS. and some info in livestron.com "L-Arginine Effects on the Brain"
http://www.livestrong.com/article/379137-l-arginine-effects-on-the-brain/I've been looking into L-Arginine as a potential supplement. What I find worisome is that Viagra and L-Arginine increase nitric oxide - though through different mechanisms.

NO has a role in several features of the disease, including disruption of the blood—brain barrier, oligodendrocyte injury and demyelination, axonal degeneration, and that it contributes to the loss of function by impairment of axonal conduction

And, from the same article:
Quote:
However, despite these considerations, the net effect of NO production in MS is not necessarily deleterious because it also has several beneficial immunomodulatory effects. These dual effects may help to explain why iNOS inhibition has not provided reliable and encouraging results in animal models of MS, but alternative approaches based on the inhibition of superoxide production, partial sodium-channel blockade, or the replacement of lost immunomodulatory function, may prove beneficial.
