By far the most common cause of ED is vascular dysfunction. When the arteries that supply the penis with blood to achieve and maintain an erection are blocked or hardened, or the lining of these arteries are damaged, blood flow is reduced. Vascular dysfunction not only affects the small arteries of the penis, but the larger coronary arteries of the heart too. Astute doctors now recognize that ED may actually be an early warning sign of impending cardiovascular disease, showing up several years before a cardiovascular event like a heart attack or stroke.2 To maintain healthy vascular function, and in turn, normal erectile function, consider these supplements:
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.
To understand the physiology of erectile dysfunction, we need to know erection first. An erection occurs when impulses from the brain and genital nerves cause blood to fill the two chambers known as the corpora cavernosa in the male penis. This causes the penis to expand and stiffen. Anything that blocks these impulses or restricts blood flow to the penis can result in ED. This block may be caused by psychological, neurologic, hormonal, arterial, or cavernosal impairment or even from a combination of all these factors.3
So, how to increase the sexual potency? Firstly, get rid of bad food habits and revise your diet consuming more foods rich in zinc, protein, vitamins, and essential fatty acids. Often, the opponents of vegetarian diet and raw food diet argue that vegetarianism/veganism and sex are incompatible. Moreover, they assert that abstinence from meat leads to a substantial decrease in male potency. Allegedly, to make a sex life active, the male diet must necessarily include meat. And more is better. In fact, this is not true. The main thing is to ensure that you get all essential nutrients from food. And the foods of plant origin are a great source of these nutrients. Let’s consider the issue in more detail.
The phrase “use it before you lose it” can be applied when it comes to helping men with ED regain normal erectile function. Pelvic exercises, more commonly known as kegel exercises, are used to promote urinary continence and sexual health. They help to strengthen the bulbocavernosus muscle, which does three things: allows the penis to engorge with blood during erection, it pumps during ejaculation, and it helps empty the urethra after urination, according to Healthline.
There are many different treatment options for erectile dysfunction but your individual diagnosis will determine which treatment option is right for you. It is important to realize that not all treatment options will work for everyone. A doctor who has specialized in men’s sexual health (typically a urologist) will be the most qualified to discuss all of your treatment options with you. Many specialists will often encourage you to schedule additional follow up appointments to review how your treatment is working for you or if a different option may be more beneficial.
In this study, 78 patients aged 25 to 50 suffering from mild to moderate erectile dysfunction were given this supplement. This study lasted 12 weeks and the size and duration of the erection was the focus of the study. At the conclusion of the study, it was determined that this supplement made a significant difference compared to the controls on parameters like sexual desire, intercourse satisfaction, orgasmic function and overall satisfaction. Side effects were mild and similar to those observed in the control group. Once the trail finished, 90 percent of those taking the VXP supplement wished to continue taking the product because of the impact they observed. 
Erectile dysfunction supplements and other natural remedies have long been used in Chinese, African and other cultures. But unlike prescription medications for erectile dysfunction, such as sildenafil (Viagra), vardenafil (Levitra, Staxyn), tadalafil (Cialis, Adcirca) and avanafil (Stendra), erectile dysfunction herbs and supplements haven't been well-studied or tested. Some can cause side effects or interact with other medications. And the amount of the active ingredient can vary greatly from product to product.
