Ancient Incans consumed this energizing Peruvian plant before battle or a bout of sex, Chris Kilham, an ethnobotanist at the University of Massachusetts at Amherst, told Outside Online. 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 sexual dysfunction to regain their libidos.
Men typically have higher zinc needs than women, which can make them more vulnerable to zinc deficiencies. In men, zinc is also needed to support healthy prostate and penile function. Keep in mind that excessive amounts of zinc can be harmful so it is best to follow package directions on the supplement you choose, should you decide to supplement with the mineral.
Research has shown that the same eating patterns that can cause heart attacks due to restricted blood flow in the coronary arteries can also impede blood flow to and within the penis. The blood flow is needed for the penis to become erect. Diets that include very few fruits and vegetables along with lots of fatty, fried, and processed foods can contribute to decreased blood circulation throughout the body.
Niacin, prescribed for more than 50 years, has been successful in treating all three types of lipids in your bloodstream. It can reduce levels of low-density lipoprotein -- LDL, or “bad,” cholesterol -- and triglycerides, as well as elevate your levels of protective high-density lipoprotein -- HDL, or “good,” cholesterol. But other medications, as well as diet and lifestyle changes, can restore your cholesterol to heart-healthy levels. If you currently take niacin and want to start taking medication to treat erectile dysfunction, ask your doctor about switching to a different type of cholesterol medication.
These results are remarkable, because it appears that not only can niacin improve short term erectile function in many men, but also can likely help to reverse arterial plaque if a comprehensive program is undertaken. Of course, neither I nor anyone else knows how safe megadosed niacin is long term, but many experts consider it safe when used under the care of a knowledgeable physician. You'll have to do your own due diligence.
Men, aged 40–80 y, were recruited from new consultations seen for erectile dysfunction at the Lahey Clinic Center for Sexual Function. Patients were screened by history and physical examination and by evaluation of nocturnal penile tumescence and rigidity with the RigiScan™ (Timm Medical Technologies, Inc., Minneapolis, USA). Candidates completed a sexual questionnaire and had morning blood tests for luteinizing hormone (LH), free testosterone, cortisol, dehydroepiandrosterone sulfate and androstenedione. Inclusion criteria included normal initial serum testosterone and prolactin levels and the presence of an organic cause of erectile dysfunction manifested by abnormal nocturnal tumescence and rigidity testing with the RigiScan™ monitor. Active smokers and men with concurrent major psychiatric problems were excluded. No other treatment for erectile dysfunction was permitted during the study. Yohimbine hydrochloride (supplied by Palisades Pharmaceuticals, Palisades, NJ, USA) was started at a dose of 5.4 mg three times a day (tid) for 4 weeks, after which the sex questionnaire was administered again and blood tests, nocturnal penile tumescence and rigidity testing were repeated. The dose of yohimbine then was increased to 10.8 mg tid for 4 additional weeks followed by a third administration of the sex questionnaire and final measurements of hormone levels and nocturnal penile tumescence and rigidity monitoring.

The substance that gives hot peppers their kick can also give you some kick in the pants: Studies have associated the natural chemical with increased testosterone levels. In animal studies, capsaicin has also shown to increase the size of sex organs, while simultaneously decreasing belly fat. A 2014 study from France also found that men who ate more spicy food had higher testosterone levels than those who ate less. You can consume capsaicin via peppers, chili powder or a cayenne supplement.
Researchers in London set out to find out if the claims about Yohimbe were true. Could the bark of a tree actually increase libido and improve impotence? They performed a double-blind trial using yohimbine for the treatment of erection inadequacy. Men, aged 18-70 years, seeking help for the secondary erection inadequacy for 6 months or longer, took part in the trial. None of the participants had any serious psychiatric disease, hypertension or liver insufficiency. Half of the men were given 5.4mg of yohimbine, the other half a placebo, for 8 weeks. Patients were assessed in 4-week intervals. After 8 weeks of treatment, 37 percent said they had good erections, as compared to only 13% in the placebo group. After the 8-week treatment, the placebo group was given the yohimbine as well, results for improved stimulated erection after the second 8-week trial increased to a total of 42 percent overall.

Besides that, dyslipidemia (and hypercholesterolemia in particular), remain undertreated in many patients diagnosed with coronary artery disease. High triglycerides, a contributor to cardiovascular dysfunction by many but not all studies, are somewhat treatable with fibrates, yet there are significant limitations for their use. Elevated fasting triglyceride levels have been shown to be a strong risk factor for ischemic heart disease, independent of other known risk factors for atherosclerosis.
Zinc distributes all over the body, so it’s difficult to test through a blood test. If you have problems with erectile dysfunction or suspect that you might have a zinc deficiency, talk with your doctor. A medical professional will be able to check your testosterone level and determine if using zinc supplements to treat your ED is an appropriate course of action.
