A lot of the problems (but many) related to ED are related to health. The more healthy you are, the higher chance you'll have of getting an erection. Certain erectile dysfunction drugs and other supplements, like L-arginine amino acid, aids in regulating blood flow. They are present in dairy, meats, and fish. If taken in large doses, it could trigger the overproduction of stomach acid, so don't take it if you are suffering from stomach ulcers or acid reflux.
