In the New World, maize was traditionally treated with lime, an alkali now shown to make niacin nutritionally available and thereby reducing the chance of developing pellagra.1 However, when in the 18th century corn cultivation was adopted worldwide, treatment with lime was not accepted because the benefit was not understood. Thus in the New World, often heavily dependent on corn, cultivators rarely suffered from pellagra, which became common only when corn became a staple that was eaten without the traditional treatment. Of interest, if maize is not so processed, it is a poor source of tryptophan as well as niacin.
People who do not have any contra-indications (see below) generally tolerate it well. However, taking yohimbe can sometimes cause side effects including: high blood pressure, headaches, anxiety, restlessness/nervousness, dizziness or shakiness. These side effects seem to affect people with a history of mental illness or mood-related problems most often. But it’s possible for them to develop in anybody.
Anxiety. There is mixed evidence about the effectiveness of yohimbine, the active ingredient in yohimbe, for treating anxiety related to phobias. Some research suggests that it does not improve anxiety when combined with exposure-based therapy used to reduce fear of flying. However, other research suggests that taking yohimbine along with exposure-based therapy helps treat claustrophobia better than exposure-based therapy alone. The effect of yohimbe bark on anxiety is not clear.
Vitamin B5 (Pantothenic acid) is irreplaceable if you wish to increase life expectancy. Vitamin B5 has a positive impact on the nervous system and intestinal motility. Calcium pantothenate is a form of vitamin B5 that has a powerful anabolic effect, enhances the synthesis of steroid hormones, and takes part in the synthesis of coenzyme A. In addition, calcium pantothenate helps release energy from foods. So, to a large extent, it improves your body’s endurance and stamina, as well as increases human tolerance to different loads.
Because the study included only subjects with dyslipidemia, the results may not be applicable to those with ED who have a normal serum lipid profile. Furthermore, patients using aspirin or NSAIDs were excluded to avoid the effect of these drugs in inhibiting prostaglandin D production, which may be one of the potential mechanisms for the effects of niacin on ED. It should be noted that it is quite common for ED patients to have coexisting cardiovascular disease that requires the use of aspirin. Therefore, further study on the interaction of aspirin and niacin in ED patients may be needed to establish the role of niacin in clinical usage.

Yohimbe is commonly taken to increase sexual excitement and to reduce sexual problems such as symptoms of erectile dysfunction (ED), also called impotence. Research shows that yohimbe may be capable of increasing blood flow to the penis or vagina. It also increases nerve impulses that play a role in orgasm. Due to how yohimbine affects blood vessels, it can cause relaxation of the penile tissue and engorgement of blood. This helps a man to maintain an erection. These effects are beneficial for both sexes when it comes to experiencing sexual satisfaction.
Three of the randomized studies (25–27) that contributed to the present study data indicated the positive role of both interval and continuous aerobic training in the dual management of both ED and cardiovascular disorders (hypertension and ischemic heart disease ,respectively); this is not surprising because of the arterogenic interrelationship between ED and several cardiovascular disorders. The physiological basis for the therapeutic role of continuous exercise in the management of both ED and some cardiovascular disorders as reported in the present study, could be related to the biochemical, neural and hormonal changes in the blood vessel walls that induce an acute and long-term blood vessel relaxation. The blood vessels might relax after each exercise session because of body warming effects; local production of certain chemicals, such lactic acid and NO; decreases in nerve activity; and changes in certain hormones and their receptors (32, 33). Over time, as the exercise is repeated, there appears to be a growing evidence of a prolonged effect. Thus, chronic (regular, longterm) physical training might reduce basal concentrations of inflammatory markers.
Although you should steer clear of supplements advertised online, research shows certain vitamins and herbs can help ED. They may help improve the health of your blood vessels, increase blood flow to the penis, and boost erectile function. If other treatments have failed, you’re not a candidate for ED medications, or you’re looking for a more natural approach, ask your doctor whether these supplements could be right for you. Here are three to discuss with your doctor:
These are not currently approved by the FDA for ED management, but they may be offered through research studies (clinical trials). Patients who are interested should discuss the risks and benefits (informed consent) of each, as well as costs before starting any clinical trials. Most therapies not approved by the FDA are not covered by government or private insurance benefits.

Saw palmetto. Saw palmetto comes from the fruit of a small palm tree. It has been used to treat symptoms in men with an enlarged prostate gland, such as difficulty urinating, and it has been recommended to treat ED caused by an enlarged prostate. However, several recent clinical trials did not show that saw palmetto works any better on an enlarged prostate than a placebo does. "There is no evidence that saw palmetto should be used to treat erectile dysfunction," says Dr. Gilbert. Like ginkgo biloba, saw palmetto can interact with some prescription medications.

Often when we start to look outside of mainstream medicine for alternative protocols to heal our health issues we replace one pill-taking protocol with another. The prescription drugs are replaced with a long list of supplements. Supplements alone, without any other lifestyle changes, will have some impact, but it will be nowhere near what they can achieve when working in a body supported with a healthy way of life.

Allow me to explain. We know that cardiovascular disease is the number-one killer of men in the United States. Well, the “vascular” part of cardiovascular disease means that the cause is really blockage of the arteries around the heart, a process called atherosclerosis. It’s proven that over half of heart attacks occur in men with normal cholesterol. And many times, heart disease develops without warnings, causing sudden cardiac arrest.  So any early warning sign can be a life saver — and might compel you to get checked out before the big one hits.


The Enlightenment proved itself to be an intellectual movement in 18th Century Europe that mobilized the power of reason to advance knowledge and reform society. It promoted intellectual transaction and opposed intolerance and abuses by both Church and State. This constituted a challenge to and disparagement of the heavy-handedness of the State. Thus, society was lifted and enlightened.
Erectile Dysfunction is an embarrassing and frustrating condition among many men. There are several reasons behind this. Most of the time, it is caused by certain medical conditions such as diabetes, heart disease, obesity, as well as low testosterone. Other reasons may also include problems in blood flow, psychological issues, nerve damage, as well as hormonal fluctuations.
Yohimbine: The main component of an African tree bark, yohimbine is probably one of the most problematic of all natural remedies for ED. Some research suggests that yohimbine can improve a type of sexual dysfunction that is linked with a drug used to treat depression. However, studies have linked yohimbine to a number of side effects, which can include anxiety, increased blood pressure, and a fast, irregular heartbeat. Like all natural remedies, yohimbine should only be used after advice and under supervision from a doctor.

When men are given supplemental testosterone it can have positive effects on erectile dysfunction as well as the “grumpy old men” syndrome of low energy, loss of drive, low libido, and loss of endurance as well as “man boobs”.  Zinc has a direct effect on the two main enzyme systems that act on testosterone: conversion of testosterone to estrogen via aromatase and the conversion of testosterone to DHT by 5 alpha reductase.   Zinc blocks the testosterone to estrogen pathway leading to more testosterone.  It turns out that only at really high zinc levels does zinc inhibit the 5 alpha reductase enzyme so when we give mild to moderate zinc supplements, DHT actually increases because there is more testosterone to feed into this pathway.   This actually benefits things because DHT has 2-3 times the times the androgen receptor affinity than testosterone.  In any case, we see an increase of testosterone and androgenic activity from DHT with zinc supplements and whether a guy has low or normal T to begin with, there is a positive change in erectile dysfunction and libido in some men due to the increased androgenic activity and less estrogen pulling in the opposite direction.  Conversely we see testosterone levels drop when a diet is low in Zinc as well as a drop in DHT.  It is important to note that this effect of increased testosterone with zinc supplementation, while well established, does not always lead to an improvement of ED and increased Libido.
A physical exam checks your total health. Examination focusing on your genitals (penis and testicles) is often done to check for ED. Based on your age and risk factors, the exam may also focus on your heart and blood system: heart, peripheral pulses and blood pressure. Based on your age and family history your doctor may do a rectal exam to check the prostate. These tests are not painful. Most patients do not need a lot of testing before starting treatment.
Research in the medical journal Experimental and Therapeutic Medicine found that supplementing with the mineral zinc, along with the vitamins folic acid and biotin, as well as the herb Rhodiola rosea improved ejaculatory control in males suffering from premature ejaculation. Premature ejaculation is a common type of sexual dysfunction that affects 20 to 30 percent of men between the ages of 18 and 55. The low incidence of any side-effects of these natural treatments may also make it preferable to drug treatments by many men.
The RigiScan™ portable home monitor recorded nocturnal penile tumescence and rigidity testing. The monitor's quantitative analysis software quantitates various parameters of tumescence and rigidity, which includes the area under the curve over time slept, reported as tumescence activity units and rigidity activity units. The reproducibility and accuracy of this technique have been reported.28 Baseline normal values were used as previously reported,29 Rigidity had to be at least 60% at the base and 50% at the tip and maintained for at least 10 min. At least half of the episodes had to meet these criteria, with a minimum of three or four episodes per night. Tumescence had to achieve a height of 3 cm at the base and 2 cm at the tip.
Minor side effects associated with erectile dysfunction medications include indigestion, runny nose and skin flushes. Sildenafil may cause temporary changes in your vision, and vardenafil may cause muscle aches and back pain. More serious side effects include hearing loss and erections that last longer than four hours. If you have cardiovascular problems, including a history of heart attacks or strokes, high or low blood pressure or vision problems such as retinitis pigmentosa, it may prove unsafe for you to take sildenafil, vardenafil or tadalafil. These medications may also interact poorly with some antibiotics, blood thinners and medications to prevent seizures and heart rhythm disorders.
An Italian study in 1994 on 63 patients with psychogenic impotence showed that yohimbine, the active ingredient in the inner bark of the Yohimbe tree, improves libido and sexual stimulation. Half of the patients were given 15mg orally of yohimbine and the antidepressant trazodone 50mg orally per day, the other half a placebo, over an 8-week period. Of the half that received the yohimbine, 71 percent had an increase in sexual desire, erectile function, and ejaculation, as compared with only 22 percent in the placebo group. Patients receiving the placebo then were given the yohimbine tablets over a new 8-week course and of that group, 74 percent showed improvement. After a 3- and 6-month follow-up, positive results were maintained in 58 percent of the patients. To me this is very notable, as the antidepressant trazodone is known to cause sexual dysfunction as a side effect.
Many studies have been conducted on this topic; their results have been challenged by lack of controlled groups and non-randomization. Randomized controlled trials (RCTs) are generally accepted as the most valid method for determining the efficacy of a therapeutic intervention, because the biases associated with other experimental designs can be avoided.Non-randomized controlled trials, can detect associations between an intervention and an outcome. But they cannot rule out the possibility that the association was caused by a third factor linked to both intervention and outcome. Random allocation ensures no systematic differences between intervention groups in factors, known and unknown, that may affect outcome. Randomized controlled trials are the most rigorous way of determining whether a cause-effect relation exists between treatment and outcome and for assessing the cost effectiveness of a treatment (45, 22).
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.
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.
3. Testosterone replacement. Before oral medications like Viagra, testosterone was routinely used to treat erectile dysfunction as it is central in the male sexual response, including the desire for sex and the process of getting an erection. Testosterone can be administered in a number of ways, for example orally, by means of an injection, skin patch, or subcutaneous (under the skin) pellet. 

Most studies related to male infertility show a clear concise relationship between zinc and ed. During a study some young men were given a diet which included very little amounts of zinc and thus they developed a zinc deficiency. When testosterone levels were measured after 20 weeks of low-zinc diet it was found that the level of the hormone had drastically reduced. The study also found that in elderly men, with an increase in the uptake of zinc, testosterone levels nearly doubled.


Exercise lowers blood pressure – a consistently high blood pressure (hypertension) can damage your arteries and cause them to harden, limiting the flow of blood to the penis and leading to cardiovascular problems. Exercise works to reduce the force required to pump blood around your body, protecting your artery linings as a result. You should aim to have a blood pressure less than 140/90mm Hg.
Once you get checked out for artery blockage and low T, there are things you can do to help treat ED besides taking medications. Yes, Viagra is now available generically (it’s called sildenafil), but it is still expensive, and many men experience side effects, like heart palpitations or blue-ish vision. Here are a few proven natural ways to help improve E.D.
