Enlargement of the prostate gland, another condition that occurs with increasing frequency in men as they age, can also cause ED. In a 2012 Swiss study, 82 men with moderate to severe symptoms of prostate enlargement, who were also experiencing problems such as ED or loss of libido, took 320 mg of saw palmetto extract daily for 8 weeks. At the end of the study, the men’s ‘International Prostate Symptom Score’ (IPSS), a method of measuring prostate health based on a questionnaire, was reduced by an average of 51 percent. In addition, their ED, libido, and other sexual functions had also improved by an average of over 40 percent. Unlike the drug approaches used in conventional medicine, which can even cause ED as a side effect, saw palmetto is very effective in treating prostate problems and is free from side effects.
In a study done to determine if vitamin D supplementation would actually help patients with ED, 143 patients with ED were tested to determine vitamin D levels. It was found that of these cases, 46 percent of patients suffered from substantial vitamin D deficiency and only 20 percent were found to have adequate levels of vitamin D. In these cases, it was also determined that inadequate arterial blood flow was the root cause of ED more commonly in patients with low vitamin D levels.  Vitamin D supplementation can improve both these parameters.
Wine – especially red wine – is a great source of the antioxidant phytochemical resveratrol, which helps open the arteries by enhancing the production of nitric oxide. Nitric oxide allows the blood vessels to expand, and this is how Viagra works. But while the little blue pill only works on tiny blood vessels, resveratrol helps your main arteries too. Make sure you stop at one or two glasses of wine – too much alcohol leads to the dreaded droop.
Studies show that just 30 minutes of walking each day can be beneficial to those fighting ED. One Harvard study linked 30 minutes of walking per day with a 41 percent drop in the risk of erectile dysfunction. Some research shows that moderate exercise can help restore sexual performance in men who are middle-aged, obese, and have been diagnosed with ED.
Encouraging evidence suggests that ginseng may be an effective herbal treatment for ED. However, further, larger, and high-quality studies are required before firm conclusions can be drawn. Promising (although very preliminary) results have also been generated for some herbal formulations. Overall, more research in the field, adhering to the CONSORT statement extension for reporting trials, is justified before the use of herbal products in ED can be recommended.
So, what do we see? The daily diet of any vegetarian or vegan includes the sufficient quantities of the above-mentioned foods. Refusing to eat meat and switching to a vegetarian or vegan diet, a man gets a number of advantages in return. Vegetarians and vegans have excess weight more rarely and are less exposed to the risk of cardiovascular diseases. All these factors have a positive effect on the male potency. If you combine adherence to the principles of good food with natural Viagra intake, you will achieve truly amazing results in the ED treatment fast.
DHEA. DHEA, or dehydroepiandrosterone, is a natural hormone that the body uses to make the male hormone testosterone. DHEA and testosterone decrease with age, just as ED increases with age, so it seems that taking DHEA might protect against ED. But Harris says that "it is unlikely that taking DHEA would raise your testosterone enough to make much difference." DHEA should not be used by people with liver problems; it also has many side effects.
Ginseng is the most common ingredient among top-selling supplements for men’s sexual health (36). The English word ginseng derives from the Chinese term renshen. Ren means “person” and shen means “plant root”. This plant has been named in this manner as its roots resemble the lower limbs of a human, Traditionally, ginseng has been used to restore and enhance the normal well-being of the body. The effects are due to ginseng’s reactions with the central nervous system, metabolism, immune function and cardiovascular system. The principal active compounds are triterpene saponins known as ginsenosides. Animal studies have suggested that specific ginsenosides may be responsible for ginseng-mediated effects on copulatory behavior (37). Ginsenoside induces smooth muscle relaxation by hyperpolarizing the smooth muscle membrane via activation of large-conductance KCa channels (38).
These drugs facilitate erection by inhibiting the PDE5 enzyme, by blocking the degradation of cyclic guanosine monophosphate (cGMP) in the cavernous smooth muscles. This inhibition results in the prolonged activity of cGMP, which further decreases intracellular calcium concentrations, maintains smooth muscle relaxation and, hence, results in rigid penile erections.
Experts don't yet know whether the vitamin folic acid (also known as folate) is an effective natural treatment for erectile dysfunction. Research has shown that for some men, taking sildenafil (Viagra) together with folic acid and vitamin B6 seemed to help with erectile dysfunction more than taking medicine alone. Some experts contend that folic acid improves the function of the blood vessels involved in erections. But scientists say they need more studies to know if folic acid helps erectile dysfunction, either alone or in combination with other treatments.
Poor sleep patterns can be a contributing factor for erectile dysfunction, Mucher says. One review published in the journal Brain Research emphasized the intricate relationship between the level of sex hormones like testosterone, sexual function, and sleep, noting that testosterone levels increase with improved sleep, and lower levels are associated with sexual dysfunction. Hormone secretion is controlled by the body’s internal clock, and sleep patterns likely help the body determine when to release certain hormones.
