If you’ve been to the health food store lately, you’ve seen shelves lined with vitamins and “organic” supplements, each claiming to boost immunity, revitalize organ function, or “promote health.” And it’s working. Supplements are currently a $30 billion industry in the US, with more than 90,000 products on the market, and vitamin use is on the rise. In fact, a recent survey in Journal of American Medicine Association showed that “52% of US adults reported use of at least 1 supplement product.”
L-arginine is an amino acid that is necessary for the lining of the blood vessels to produce nitric oxide. Nitric oxide allows the blood vessels to relax, thus improving blood flow throughout the body, including to the penis. Studies on L-arginine and erectile dysfunction have used between 2,000-5,000 mg a day in divided doses.ii Supplemental arginine is best taken on an empty stomach.3
A recent study found that men with erectile dysfunction who ate pistachio nuts every day for three weeks experienced significant improvement in sexual issues, including ED, sexual desire, and overall sexual satisfaction. The benefits of pistachios for erection problems may be due to a protein called arginine, which may help relax blood vessels. "This is another example of how good circulation is good for sexual health, which is good news because I eat a lot of pistachios," says Dr. Daneshgari.
For many men, stopping smoking is an erectile dysfunction remedy, particularly when ED is the result of vascular disease, which occurs when blood supply to the penis becomes restricted because of blockage or narrowing of the arteries. Smoking and even smokeless tobacco can also cause the narrowing of important blood vessels and have the same negative impact.
