Arginine and mental acuity
I have some questions about taking arginine. I am going to start taking L-arginine tomorrow but I have doubt related to a comment I read in this forum. A member says arginine is very bad for mental acuity. Are there anyone who experienced something like that ? Considering the good effects on blood vessels , I think it must be beneficial for brain too. But am I thinking so simple? Are there different factors ? It is very important for me please write your comments.
Other question, I read people here takes 5 g a day. In my country there are only 500 mg capsules and it offers only 1 capsule a day in prospectus. Do I have to take 10 capsules a day ? Why this much dose? Doesn’t it work if I take 500mg a day?
