I can vouch for arginine (heart tonic) for ED, as I suffered for years and had virtually given up till I was told about this.
L-Arginine works sometime because this is another pathway for the body to generate nitric oxide. However, according to some studies, L-Arginine supplementation isn't effective for many people. I think that by following the natural path I recommended in my post on Nitric Acid in this section, you will have better success and you won't have to take any supplements. By consuming nitrates from vegetables, especially beetroot, and by creating and maintaining a healthy microbiome (through the consumption of milk kefir), you will be creating plenty of nitric oxide for cardiovascular health. ED is really only a symptom of cardiovascular issues.
