Louis Ignarro reccomends 4 to 6 grams l-arginine per day and 200 to 1,000 mg l-citrulline per day, taken along with the l-arginine, especially to help reverse cardiovascular disease. Ignarro was awarded the Nobel Price in Medicine for his discovery of the importance of nitric oxide to the cardiovascular system, you know.
Many researchers reccomend it too. Expert in Germany is Rainer Böger University Hamburg. If you suffer a heart attack in Heidelberg, you'll get at first injections with arginine.
Especially dieseases like cardiovascular disease, heart failure, stroke or increased blood pressure can be associated with reduced arginine concentration in the blood. I eat all the things you mention. But my blood check showed arginine and other amino acids are too low. Since then, at first "measure" and then "supplement". And control ADMA level.
I have spent some effort finding out studies that say l-citrulline alone is better & safer than l-arginine (or both). But am no expert, I take 4 - 6 gr a day when exercising or at a full days work.
But now that I am 9 months out of my CABG I may want to reexamine the protocols about this.
Please tell more, how long have you been doing these 2?
