A study in the Journal of Sexual Medicine found that a large percentage of men with ED also have low levels of vitamin D. If you’re experiencing ED, you may want to have your level of vitamin D checked. Other symptoms of a low vitamin D level may be too subtle to notice. However, if you have serious vitamin D deficiency, you may have bone pain or muscle weakness. Vitamin D levels can be checked with a simple blood test and for most people corrected with a supplement.
Despite the name, horny goat weed actually helps improve your erection, not libido.  Botanically known as epimedium, this herb has been used by the Chinese for centuries to treat, among other things, low libido and erectile dysfunction. “A growing body of research shows that isolated icariin—the extract of epimedium—inhibits the enzyme phosphodiesterase-5 (PDE-5) and significantly increases nitric oxide synthase, helping to improve erectile function,” says Fisch. In fact, this is the same mechanism that Viagra works through (but the herb comes with a way better name).

For example, you’ll often hear that watermelon is a great remedy for ED.  This belief seems to come from a study done in 20075, which showed that consuming watermelon could raised levels of L-arginine in the bloodstream.  L-arginine is used in the production of nitric oxide (NO), which is a key to healthy erections (see our article, “How Do Erections Work“).  However, the study did not show that consuming watermelon actually improved erections.  Also, the subjects consumed the equivalent of three eight-ounce glasses of watermelon juice per day!
To achieve and maintain an erection, healthy blood vessels and an optimum blood flow are essential. Significantly, therefore, Dr. Rath’s research has proven that specific micronutrients play key roles in maintaining the structural integrity of blood vessels and optimizing blood flow. Such micronutrients include vitamins C and E, the amino acids lysine and proline, and the mineral copper.

A recent study in the journal Circulation found that flavonoids in dark chocolate improve circulation. That could be good for erection problems that are due to poor circulation. Flavonoids are naturally-occurring antioxidants that protect plants from toxins and help repair cell damage. Studies show that flavonoids and other antioxidants have similar effects on people. They may help lower blood pressure and decrease cholesterol, both of which are factors that contribute to erectile dysfunction.
Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship.

He is board-certified in Internal Medicine and Rheumatology.
Recent University of Texas findings suggest that men who drink two to three cups of java a day—or 85 to 170 milligrams of caffeine from other beverages—are 42 percent less likely to have erectile dysfunction than those who consume up to seven milligrams of the stimulant daily. And those who throw back four to seven cups were 39 percent less likely to have the condition than their less jittery counterparts. The trend holds true among overweight, obese and hypertensive men, but not for those with diabetes, a condition that often causes the issue. So, how exactly does drinking coffee keep things going strong? The scientists say that the stimulant triggers a series of reactions in the body that ultimately increase blood flow south.

Ancient Incans consumed this energizing Peruvian plant, says Chris Kilham, an ethnobotanist at the University of Massachusetts at Amherst. Maca increases sexual appetite, stamina, endurance and fertility. One 2008 study conducted at the Depression Clinical and Research Program at Massachusetts General Hospital in Boston found that maca helped people with antidepressant-induced dysfunction to regain their libidos.

If you can't take one of these oral medications, your physician may have you try Caverject (alprostadil for injection), a hormone that you inject into your penis using a fine needle, or Muse (alprostadil urogenital), a tiny suppository that you insert into the tip of the penis. Both of these will bring on an erection within five to 15 minutes without sexual stimulation.
The use of shock wave therapy has revolutionized the treatment of many aspects of medicine. High intensity extracorporeal shockwave therapy has been used for the treatment of nephro-urolithiasis while medium intensity shockwave therapy is used by orthopaedic surgeons to treat joint pain as well as tendinitis. Low intensity shockwaves therapy was first noted to improve ischaemia-induced myocardial dysfunction in animal studies when low intensity shockwaves were applied to porcine myocardium (13). Shockwaves induces a localized stress on cell membranes in the same way that shear stress affects endothelial cell membranes (14) and this triggers the release of angiogenic factors, such as increased NO production through increased activity of endothelial NO synthase (eNOS) and neuronal NO synthase (nNOS), platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) (15). These shockwaves also cause membrane hyperpolarization (16), activation of the Ras signaling pathway, non-enzymatic synthesis of NO and induction of stress fibers and intercellular gaps (17).

Although you should steer clear of supplements advertised online, research shows certain vitamins and herbs can help ED. They may help improve the health of your blood vessels, increase blood flow to the penis, and boost erectile function. If other treatments have failed, you’re not a candidate for ED medications, or you’re looking for a more natural approach, ask your doctor whether these supplements could be right for you. Here are three to discuss with your doctor:
Yohimbe A number of clinical trials have shown that the primary component of this bark from an African tree can improve sexual dysfunction associated with selective-serotonin reuptake inhibitors (SSRIs) used to treat depression. This herb has been linked to a number of side effects, including increased blood pressure, fast or irregular heartbeat, and anxiety. Yohimbe shouldn't be used without a doctor's supervision.
