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.
Leafy green vegetables, like celery and spinach, may increase circulation because of their high concentration of nitrates. Beet juice has been found to be really high in nitrates. Nitrates are vasodilators, which means they open up blood vessels and increase blood flow. Many years before the U.S. Food and Drug Administration approved the first ED drug in 1998, several case reports on the beneficial effects of nitrates for erectile dysfunction had already been published. The ED drugs used today are based on the relaxing effects of nitrates on the blood vessels that supply the penis.
When considering vitamin supplementation for erectile dysfunction, one of the first vitamins that you may come across in literature would be Vitamin D. This is a vitamin that can be easily obtained through many types of dairy products like milk, cheese, and yogurt and is also in abundance if you live in a tropical climate. Sunlight is able to give us a natural dose of vitamin D daily.  Although vitamin D is usually associated with improving bone strength and prevention osteoporosis, another valuable feat of vitamin D is the fact that it helps reduce atherosclerosis. Studies confirm that there is a similar underlying mechanism that occurs between conditions like cardiovascular disease and erectile dysfunction. As blood vessels are damaged and filled with plaques, the diameter for blood to flow through is gradually reduced. After a few years, the amount of blood may be reduced substantially. Vitamin D is able to help activate cells that remove some of these dangerous plaques and delay the onset of ED. 
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).
Another potential cause of ED is prediabetes and diabetes—35-50 percent of men with diabetes also have ED. Chronically elevated blood sugar damages the arteries (there’s the vascular connection again) and nerves, including those that stimulate the penis. Prediabetes and diabetes are also generally accompanied by excess weight, especially around the mid-section. These excess fat cells convert testosterone into estrogen, negatively altering the testosterone to estrogen ratio. This excess estrogen, independent of prediabetes and diabetes, interferes with the hormonal cascade necessary to produce and maintain an erection. Although many men may reach for a testosterone booster, a more effective means is to improve the body’s metabolism and elimination of estrogen and to lose excess weight around the middle. To support healthy blood sugar balance and estrogen metabolism try:
A 2000 study conducted at the Institute of Sexology in (where else?) Paris found that muira puama, a Brazilian shrub traditionally used in South African folk medicine as an aphrodisiac, increased libido in a majority of men who complained of impotence and a lack of desire. Other studies show this happy-making herb also counteracts chronic stress, depression and nervous exhaustion.
Do not exceed 1 capsule in 24 hours. This is only intended for those 18 and over. Do not use if you are pregnant, nursing, or intend on becoming pregnant. If you have any current heart issues, such as but not limited to, hypertension, heart disease, and high cholesterol do not use. If you have any other medical issues such as prostate cancer and prostate enlargement do not take. Do not take this product if you're on any medications such as MAOI's or nitrates. Consult with your physician or health care provider to using the product.
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.
The B vitamin folic acid is good for cardiovascular health. Keeping your blood flowing smoothly is a key to preventing and even treating erectile dysfunction (ED). After all, ED is often an early warning sign of heart problems. In particular, some men have high levels of homocysteine, which can contribute to heart problems. Findings show that eating foods high in folate and taking folic acid supplements may help lower high homocysteine levels. Lots of foods contain folic acid, including spinach, tomatoes, and orange juice. But most of us don’t get enough of these heart healthy foods in our daily diet. To boost folic acid, look for a supplement with about 525 milligrams (mg) of this vitamin. That’s good advice for everyone, and might help with your ED. Research suggests that for some men with ED and high homocysteine levels, taking folic acid may be a key to helping ED medications like Viagra perform well.
Korean red ginseng, also known as Asian ginseng or Chinese ginseng, is believed to be a highly effective natural remedy for treating ED. It is a traditional Asian remedy for sexual dysfunction and is widely used in the United States. Studies have shown that red ginseng can have significant therapeutic effects on penile rigidity and girth, libido, and patient satisfaction. It also has a reassuring safety profile, making it one of the most popular and proven natural remedy for ED.12
He might have been introduced to it by some of his pals (if that is so you might need to make him understand that some of his friends are a bad influence and stop befriending these kids). 7. PIED ( porn induced erectile dysfunction- it is a new condition that most men who were watching porn for some time get it sooner or later, some REALY scary stuff for a man!). Your son sounds like a decent kid who is crying for help.
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.
