The oyster has always had an aphrodisiac reputation. One reason may be that oysters have high levels of the mineral zinc, which plays an important role in the production of the male hormone testosterone, and low levels of testosterone could be one reason for erectile dysfunction. Research presented at an American Chemical Society meeting may offer another connection: Raw shellfish contain compounds that stimulate the release of sexual hormones in both men and women.
Between 2001–2006, one-third of the US population had insufficient amounts of vitamin D, according to the Institute of Medicine. Risk factors for vitamin D deficiency include obesity and high BMI, not enough sun exposure or outdoor activity, having darker skin and suffering from certain from inflammatory conditions like Crohn’s disease. You can get a blood test to find out if you’re vitamin D deficient.
Saw palmetto. Saw palmetto comes from the fruit of a small palm tree. It has been used to treat symptoms in men with an enlarged prostate gland, such as difficulty urinating, and it has been recommended to treat ED caused by an enlarged prostate. However, several recent clinical trials did not show that saw palmetto works any better on an enlarged prostate than a placebo does. "There is no evidence that saw palmetto should be used to treat erectile dysfunction," says Dr. Gilbert. Like ginkgo biloba, saw palmetto can interact with some prescription medications.
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.

A cold slice of watermelon can do more than just satisfy thirst and hunger during the warm summer months; it can help with bedroom satisfaction. Citrulline, the amino acid found in high concentrations of watermelon, is found to improve blood flow to the penis. A 2011 study revealed men who suffered from mild to moderate ED and took L-citrulline supplementation showed an improvement with their erectile function and were very satisfied. Natural watermelon juice, or “nature’s Viagra,” can also be easier on the stomach, since taking pills like Viagra can cause nausea and diarrhea.
A daily dose of niacin improves erectile function, particularly in men with high cholesterol, according to a 2011 study in The Journal of Sexual Medicine. The vitamin helps increase blood flow and reduce inflammation—one of the underlying causes of both high cholesterol and erectile dysfunction. “Vitamin B3 is also used to make sex hormones and other important chemical-signal molecules,” says Fisch. Like many of the others on our list, this tablet is most powerful when taken in conjunction with others: A cocktail of propionyl, L-carnitine, L-arginine, and niacin taken for three months improved 40% of erections in a study from researchers at Sapienza University of Rome in Italy.

Persons with metabolic syndrome can be identified by a distinct pattern of abdominal obesity (waist circumference >40 inches in men), atherogenic dyslipidemia (triglycerides ≥150 mg per 100 ml, HDL <40 mg per 100 ml, small LDL particles and normal or slightly elevated LDL), hypertension (≥130/85 mm Hg), insulin resistance (fasting blood glucose ≥10 0 mg per 100 ml), and elevated levels of prothrombotic and proinflammatory markers. Metabolic syndrome and insulin resistance are closely linked to ED. In one recently conducted study of 120 men with ED and no evidence of diabetes, 40% of patients fulfilled strict criteria for metabolic syndrome, and 73% were insulin resistant.12

Much of the evidence shows high rates of vitamin D deficiency in patients with erectile dysfunction. In fact, one study of 3,400 participants found that men with vitamin D deficiency were 32% more likely to have trouble with erections when all other risk factors were controlled for. It’s a little on the nose that you need vitamin D for your “D,” but hey—science can be funny too.
Erectile dysfunction (ED) is commonly called impotence. It’s a condition in which a man can’t achieve or maintain an erection during sexual performance. Symptoms may also include reduced sexual desire or libido. Your doctor is likely to diagnose you with ED if the condition lasts for more than a few weeks or months. ED affects as many as 30 million men in the United States.
