Taking one of these tablets will not automatically produce an erection. Sexual stimulation is needed first to cause the release of nitric oxide from your penile nerves. These medications amplify that signal, allowing some men to function normally. Oral erectile dysfunction medications are not aphrodisiacs, will not cause excitement and are not needed in men who get normal erections.
Most importantly, herbal supplements are not well regulated in the United States.  Studies have shown that 40-50% of herbal supplements do not even contain the supposed main ingredient, and many contain substances that are not listed which may have dangerous side effects2.  Another study found that over two thirds of the products tested had substituted other plant species for the plants listed on the label, and a third of products also contained other fillers or contaminants3.  A study by the New York State Attorney General of herbal products sold at GNC, Target, Walgreens, and Walmart found that four out of every five products didn’t contain the ingredient they claimed!  Fourteen US states and territories have petitioned Congress to regulate the herbal supplements industry.
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.
Nettle root extracts are known for their ability to restore normal production of important sex hormones, such as testosterone. The primary action of nettle root is linked to its action on the glands that produce testosterone. Nettle root contains serotonin and acetylcholine, both of which directly stimulate testosterone production and boost the functioning of these vital glands.

“Obecalp” is “placebo” spelled backwards. It might help – treatment with inactive placebos (inert substances used in evaluation of new drug treatments) works about one-third of the time in scientific studies when patients don’t know they’re getting a fake drug. Placebos are generally safe since they contain no known active agent. (However, I personally never give patients inactive placebos, and many physicians regard them as unethical.)

Many products contain undocumented “fillers” that can cause allergic reactions.  In recent years, the FDA has found over 300 herbal products that contain hidden, deceptively labeled, or dangerous ingredients4. And since 2015, the FDA has released public warnings on more than 160 ED supplements and “male enhancement” products found to contain dangerous ingredients and contaminants5 .   An independent study of FDA data, conducted in 2018, found almost 800 herbal supplements that contained unlisted ingredients6.

There have been some studies to suggest that a placebo effect that improves ED may work for some men. One study found that men taking an oral placebo pill showed as much improvement in ED symptoms as men who took actual medication to improve ED. Conversely, men who were given therapeutic suggestions to improve ED did not see signs of symptom improvement.

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:
Another natural treatment for erectile dysfunction to consider would be vitamin E. This is a vitamin that has been linked to chronic diseases in the past due to the antioxidant effects of this vitamin. Considering ED could be a manifestation of another chronic condition, it makes sense that vitamin E may have a role in reducing the symptoms of the disease. As a person ages, it is natural for the body to undergo more oxidative stress and damage as cells do not function as well as they once did. Rats who were given supplemental vitamin E were found to have reduced levels of oxidative damage to their tissues and had levels of NO and other factors that help induce an erection more similar to younger rats compared to rats without vitamin E supplementation. If patients incorporate vitamin E into their vitamins and dietary supplements for ED, their ED should improve. [9]

L-arginine is an amino acid that is necessary for the lining of the blood vessels to produce nitric oxide. Nitric oxide allows the blood vessels to relax, thus improving blood flow throughout the body, including to the penis. Studies on L-arginine and erectile dysfunction have used between 2,000-5,000 mg a day in divided doses.ii Supplemental arginine is best taken on an empty stomach.3
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

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.

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. [11] 
If you like your food like you like your lovers—sweet and spicy—you’re in luck. Ginger is another food that can improve your bedroom life by aiding blood flow and improving artery health. According to a study in the International Journal of Cardiology, consuming a mere teaspoon of the stuff a few times a week is all you need to reap the heart-healthy benefits. The spice has also been shown to boost levels of testosterone and sperm viability. So go ahead and place that second order of sushi this week—just don’t leave the ginger on your plate.
Quassinoids isolated from Tongkat Ali have been reputed to be anti-tumor, anti-malarial, anti-amoebic and anti-inflammatory. Its leaves are used for washing itches, its fruits for the treatment of dysentery, its bark used as a vermifuge, the taproots used for treatment of hypertension and the root bark for treatment of diarrhea and fever. The roots extracts are used for sexual dysfunction, aging, malaria, cancer, diabetes, anxiety, aches, constipation, exercise recovery, fever, increased energy, increased strength, leukemia, osteoporosis, stress and syphilis. Animal studies done on middle age sex rats showed enhancement of the sexual qualities in terms of hesitation time among middle aged rats (46).
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!

Researchers at Johns Hopkins University last year looked at 3,400 healthy Americans and found that men who were vitamin D deficient were 32% more likely to have trouble getting it up than those with sufficient levels, even after adjusting for other ED risk factors. In fact, the connection is so common, Walker says D levels are something he always checks in ED patients. Why? The sunshine vitamin is crucial for keeping the endothelial cells that line blood vessels healthy. Without enough of the stuff, blood flow is inhibited, affecting everything from your heart to your hard-on.
Personally, I think you are right. My husband had no problems with erectile dysfunction,until porn entered his life, and it was all downhill (way down), from there. When he finally quit porn, it actually took 2 yrs for my husband to completely regain function and be able to keep an erection. My husband is 59 yrs old, and I guess the older you are, the more difficult it is to regain function from Porn ED. Many people easily dismiss the idea that porn may be THEE problem. They shouldn't.
Move a muscle, but we're not talking about your biceps. A strong pelvic floor enhances rigidity during erections and helps keep blood from leaving the penis by pressing on a key vein. In a British trial, three months of twice-daily sets of Kegel exercises (which strengthen these muscles), combined with biofeedback and advice on lifestyle changes — quitting smoking, losing weight, limiting alcohol — worked far better than just advice on lifestyle changes.
This IKEA-cafeteria staple can actually help you put things together in the bedroom. In addition to packing four times your daily requirement of Vitamin B12 in one average-sized filet, herring is also rich in magnesium, which boosts testosterone and keeps sperm healthy and viable. On top of that, oily fish like herring are sky-high in vitamin D, which can help you get and keep it up. In a recent study published in the Journal of Sexual Medicine, Italian researchers examined 143 men with ED; 80% had suboptimal levels of the nutrient, and the men with severe ED had a 24% lower level of D than those with a mild form of the condition. The theory is that low levels of D promote dysfunctional blood vessels and a shortage of nitric oxide.
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.
