Along with promoting overall health, a sufficient daily magnesium intake can help significantly if you take zinc to promote healthy erectile function or to help alleviate ED. Zinc is often recommended as a natural ED remedy, particularly for men who have a zinc deficiency, according to MayoClinic.com. Magnesium helps regulate zinc levels in the body to support healthy erectile function. Herbs, vitamins and minerals, including magnesium, haven’t been widely studied in terms of their true benefits for men with ED or other erectile problems, but maintaining adequate levels of essential vitamins and minerals may help a doctor narrow down the cause of such problems.
Diet and lifestyle changes should come first when treating male sexual dysfunction. Any man experiencing erectile dysfunction should see a doctor right away to determine the cause and to diagnose any underlying health condition that may be contributing to this issue. Herbs can be a great way to support a man experiencing any type of sexual dysfunction. In the case of impotence, Yohimbe may be a great help support to the body when working to support a man through this very difficult reproductive issue.
Counselling or sex therapy (58% of people find this works for them) –mind-related causes of erectile dysfunction can affect anyone. They are more likely if you experience erectile dysfunction at a younger age. Talking to a counsellor or therapist can help some people overcome erectile dysfunction related to these problems, possibly for good. They can also help you if your erectile dysfunction is causing you stress, as this can make matters worse.
Thirty two male rats were randomly assigned to four groups and submitted to one of the following daily treatment regimens: (a) 1 mg of ZnSO4 dissolved in 1 ml of distilled water. (b) 5 mg of ZnSO4 dissolved in 1 ml of distilled water (c) 10 mg of ZnSO4 dissolved in 1 ml of distilled water. Controls were provided with 1 ml of distilled water. Supplementation was done orally using a feeding tube. These daily regimens were continued for two weeks (daily at 17.00 hours) and housed two per cage.
Supplementation of 5 mg of zinc/day for two weeks led to a prolongation of ejaculatory latency; 711.6 sec. (SEM 85.47) vs. 489.50 sec. (SEM 67.66), P < 0.05 and an increase in number of penile thrusting; 52.80 (SEM 11.28) vs. 26.50 (SEM 6.17), P < 0.05, compared to controls. The same group had elevated prolactin (PRL) and testosterone (T) levels compared to controls at the end of treatment period; PRL- 7.22 ng/dl (SEM 3.68) vs. 2.90 ng/dl (SEM 0.34) and T- 8.21 ng/ml (SEM 6.09) vs. 2.39 ng/ml (SEM 1.79), P < 0.05. In contrast, reduction of libido was evident in the same group, but this effect was not statistically significant (P > 0.05). However, partner preference index was positive and 5 mg zinc supplementation did not exert a significant adverse effect on the muscle strength and co-ordination. The subset of rats supplemented with 1 mg/day did not show a difference from the control group while supplementation with 10 mg/day led to a reduction of the libido index, number of mounts and intromissions.

Guay and Spark observed independently (unpublished data) that yohimbine was associated with a very poor response in cigarette smokers. This is believed to be relevant, because studies several decades ago may have included a large percentage of smokers, which only recently has been recognized as a risk factor for erectile dysfunction. We tested this hypothesis by studying nonsmoking men with documented organic impotence and by judging whether any possible effect might be related to adrenal or testicular hormones, which, to our knowledge, has not been studied.
The development of successful sexual behavior involves not only important neuroendocrine and local genital changes that begin at puberty, but also psychological and social influences that occur both before and after puberty.[7,8] Sexual behavior in males is regulated mainly by internal patterns of hormones; i.e. T, progesterone and PRL. These hormones are modulated by the male interactions with the social environment.[9]
Derived from the bark of a West African evergreen tree, yohimbe was the go-to ‘script for a wonky willy prior to the advent of wonder drugs like Viagra, Walker says. “Yohimbe enhances sexual performance both by blocking certain neurotransmitters in the brain and by increasing the release of nitric oxide in the cavernosal nerves of the penis,” he explains. And it pairs well with other erection-friendly tablets: A 2010 study in the Iranian Journal of Psychiatry found that a combination of yohimbe and L-arginine successfully helps guys get it up. However, yohimbe also has a handful of side effects, including elevated blood pressure and anxiety, so definitely talk to your doctor before you start on the supp.
The concentration of yohimbine in commercial supplements may vary from one manufacturer to another. A chemical analysis conducted on 26 brands of yohimbe supplement shows that nine products contain no yohimbe extract at all, while eight products contain only small amounts of yohimbine — approximately 0.1 to 1 parts per million (ppm), which is significantly low compared to 7,089 ppm yohimbine in an authentic yohimbe bark.3
Uses and risks of viagra Viagra treats erectile dysfunction and pulmonary arterial hypertension. For sexual purposes, it helps someone with erectile dysfunction achieve and maintain an erection. However, Viagra can have unpleasant side effects, and an overdose can be serious. We cover everything you need to know about Viagra in this article. Read now

DHEA. Dehydroepiandrosterone (DHEA) is a hormone produced in your body’s adrenal gland that aids in the production of testosterone and other hormones. Since testosterone is critical for healthy male sexuality, supplementing with DHEA may help with issues like sluggish libido and impotence. One double-blind, placebo-controlled study found subjects given 50 milligrams of DHEA every day for six months experienced improvement in symptoms of E.D.
What it’ll do for you: “Yohimbe dilates the blood vessels and can lower blood pressure,” says Dr. Patrick M. Fratellone, an integrated physician with a practice in Manhattan. “So experts figured, if it can do that, it must give you an erection and treat erectile dysfunction.” Some proponents say that yohimbe extracts are powerful antioxidants that can prevent heart attacks, act as a stimulant and an anti-depressant, and an aid to weight loss. Here, a closer look at the key benefits:
How it works: Magnesium makes it harder for your testosterone to bind onto proteins and allows for more of it to remain “free” in your bloodstream – which is exactly how you want it to be for a higher sex drive. Higher levels of free testosterone makes for more desire. Magnesium also combats anxiety and prevents depressive feelings, helping you enjoy yourself more.
Although there have been sufficient data on the relationship between ED and several wellrecognized risk factors which including aging, coronary artery disease, atherosclerosis, diabetes mellitus, dyslipidemia, high blood pressure, and pelvic surgeries, little attention has been paid by the urologists to the role of lifestyle factors in ED. However, accumulating data from basic science and clinical studies have determined a link between the occurrence of ED and a number of lifestyle factors, such as smoking, obesity, alcohol consumption, and lack of physical activity. The application of findings from animal and human studies to the clinical practice regarding the modification of lifestyle factors could help to improve ED as well as reducing the risks of developing cardiovascular diseases (14).

Participants in this study gradually increased their daily intake of niacin from 250 mg to 3,000 mg over 36 weeks. Nine of the 23 people who were taking immediate-release niacin withdrew from the study early because of facial flushing, fatigue, or skin discoloration. Eighteen of the 23 who were taking 3,000 mg daily of sustained-release niacin dropped out due to upset stomachs, fatigue, or abnormal liver function tests. All of these side effects disappeared once the participants stopped taking the vitamin. Additional cause for concern comes from other reports suggesting that high doses of sustained-release niacin can cause jaundice and liver failure.


They found that men who exercised the most were also the most likely to have higher scores in sexual function. Specifically, those who expended 18 METS, or metabolic equivalents, per week were most likely to enjoy sex. METS is a physiological measurement that denotes the amount of energy a person spends on a specific activity, as well as the intensity of it. According to the researchers, 18 METS was equal to about two hours of strenuous exercise like running or swimming, 3.5 hours of moderate-intensity exercise, or six hours of light exercise.   
Pelvic floor exercises are actually good as they can enhance the strength of the pelvic floor muscles. These exercises are commonly called Kegel exercises. These are the types of exercises that women usually perform in order to regain their muscle tone right after childbirth. They are also known to enhance urinary continence and overall male sexual health.
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.
Consequently, this negatively affects sexual function. Finally, if you frequently suffer from stress, then Vitamin B2 deficiency surely takes place. And the symptoms of this deficiency include peeling lips, cracked lips, stomatitis, tongue inflammation, skin lesions resembling eczema, conjunctivitis, photophobia, lacrimation, and decrement in visual acuity.
Clinically I have seen these results in doses of just 20 mg twice daily.   It is important to note that prolonged zinc supplementation can lead to lowered copper levels so it is not advisable to continue this therapy unless it is in a cyclical nature.  For those on long term zinc there are combination products with Zinc and Copper.   In cases where some prescriptions that lower zinc are given, like acid lowering meds, thiazide diuretics and ACE inhibitors, or in renal dialysis patients, this chronic monitoring of zinc may lead to longer term supplementation.
Athletes or dieters sometimes use products containing yohimbe to help promote easier weight loss, especially from body fat, and to increase energy expenditure. Some have speculated that it may help increase muscle mass and endurance while cutting fat. But there’s not much evidence from studies that this is necessarily true. Yohimbe does seem to have potential to increase energy expenditure by acting as a stimulant, increasing adrenaline levels in the body and potentially preventing fatigue during or following exercise.
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.
It is now thought that ED is part of the cardiovascular disease complex related to metabolic syndrome (MS). Although endothelial dysfunction and atherosclerosis are believed to be part of the main mechanisms for ED in patients with MS, other mechanisms account for ED in MS include androgen deficiency, drugs, the veno-occlusive mechanism, etc. Because dyslipidemia is one of the key risk factors for the development of endothelial dysfunction and atherosclerosis in MS patients, there is a close relationship between ED and dyslipidemia.
Did you copy past all that information without research just to get your post count up? WTF! Your mixing the instant Niacin which is the best and the time release niacin which is THE TOXIC version of niacin because some fat ass pussy whiner did not like the flushing. The real Niacin has no significant side effects. If you take to much you feel nauseated and at those levels you are still WAY BELOW what would be considered toxic for your body. Niacin actually makes your erections harder and your penis slightly increases in size. If you are having a hard time getting it up, it's something else. I also strongly advise to take niacin just before bed time as it will lower your stamina. I do not fully understand why it does this. It has something to do with ity regulating the fats in your blood. Niacin is also a sleep aide.
However, for most men who experience erectile dysfunction, their overall experience can be improved even further through regular exercise. There are many reasons why exercise improves sexual satisfaction. For one thing, regular, sustained exercise can lead to the release of chemicals called endorphins that are responsible for the so-called runner’s high, and which stimulate the release of sex hormones. Exercise also generally improves mood and imparts a sense of calm afterward, with lower heart rate, lower blood pressure, better digestion, and lower levels of stress hormones.
There was a higher incidence of adverse events in those taking niacin. However, most patients could tolerate it at the maximum dosage (1,500 mg/day). With this in mind, niacin could be an alternative choice of treatment for patients with ED. Despite the success of phosphodiesterase type 5 inhibitors (PDE5 inhibitors), such as sildenafil, only around 60–70% of patients have a satisfactory response to this class of drugs. And there are adverse effects such as headache, flushing, dyspepsia, nasal congestion, and impaired vision, including photophobia and blurred vision. Hence, there is a need to develop other therapeutic agents for those patients who do not respond satisfactorily to PDE5 inhibitors or are contraindicated for those such as sildenafil.
L-arginine. L-arginine is an important amino acid that the body needs to build proteins. Because L-arginine has been shown to improve blood flow, some alternative practitioners have recommended that the supplements be used to treat ED. The Natural Medicines Comprehensive Database, which is a reliable authority on alternative medicines, says L-arginine is possibly effective for treating erectile dysfunction. But Harris warns that "although this supplement could improve blood flow, side effects can be dangerous." L-arginine can cause an allergic reaction or worsen asthma in some people; it can also lower blood pressure.
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).

You can find this compound as a standalone ingredient in capsule, tablet, or tea form as well as a component of popular pre-workouts and fat burners. Yohimbine is not for everyone - even with moderate dosages it can increase the frequency and severity of panic attacks in high-anxiety individuals, interfere with medications, as well as cause headaches, dizziness, and nausea.

Due to its ability to inhibit actions of the sympathetic nervous system, yohimbe can help to bring blood pressure levels back to balance. This is is why it’s used to sometimes increase blood flow, such as to tissues of the reproductive organs.  Or, also why it’s used to treat hypotension (abnormally low blood pressure). It may also be helpful for stimulating nerves and treating fatigue or symptoms of depression.
Depending on dosage, yohimbine can either increase or decrease blood pressure Small doses can increase blood pressure. Higher doses can lead to a potentially dangerous drop in blood pressure. Higher doses of oral yohimbine may have numerous side effects, such as rapid heart rate, overstimulation, unusual blood pressure, cold sweating, and insomnia.
ICI therapy often produces a reliable erection, which comes down after 20-30 minutes or with climax. Since the ICI erection is not regulated by your penile nerves, you should not be surprised if the erection lasts after orgasm. The most common side effect of ICI therapy is a prolonged erection. Prolonged erections (>1 hour) can be reversed by a second injection (antidote) in the office.

In the end, open and honest communication with your therapist will yield the best course of action. If you do decide to try pelvic floor PT, a comprehensive evaluation will determine what exactly is going on with your muscles. They may be tight and weak or they could have poor coordination. So my advice for those suffering from erectile dysfunction is this: before you try kegels, make an appointment with your pelvic floor therapist.
Long prescribed for women who want to restore muscle tone after childbirth, pelvic floor exercises, also known as Kegel exercises, can benefit men significantly too. A study by researchers at the University of West of England in Bristol showed that pelvic floor exercises can help men with erectile dysfunction and premature ejaculation. Furthermore, experts think these exercises can make orgasms stronger. Once learned, pelvic floor exercises can be done any time, even while doing other things.
Men can judge themselves pretty harshly when it comes to their performance in between the sheets. The unsettling fear of not being able to rise to the occasion becomes a reccurring nightmare for men that is often equated with failure, loss of dignity, and masculinity. If you suffer from erectile dysfunction (ED), don’t be so hard on yourself, since impotence can almost always be improved with treatment, without having to rely on Viagra or other medications. Whether you suffer from ED, or hope to prevent the condition, here are six tips to overcome impotence without the side effects of the little blue pill.
Stimulant drugs speed up the nervous system. By speeding up the nervous system, stimulant medications can make you feel jittery and speed up your heartbeat. Yohimbe might also speed up the nervous system. Taking yohimbe along with stimulant drugs might cause serious problems including increased heart rate and high blood pressure. Avoid taking stimulant drugs along with yohimbe.

1. Increased Blood Flow in Men with Lower Niacin Levels.  Of course, there is a lot to an erection, but I think just about everyone would agree that the #1 goal is to increase something called endothelial function.  The endothelium is the delicate lining of the arteries that pumps out nitric oxide and relaxes the arteries.  And, of course, a relaxed, i.e. more open artery is one that allows more blood to flow into your arm, your leg or your brain.  And I'm sure I don't need to explain why increased blood flow into your penile arteries is critical for erectile strength.

Yohimbine significantly increased subjective measurements of sexual desire, sexual satisfaction, frequency of sexual contacts, and erection quality during sexual intercourse. Each subject also underwent a sleep study and researchers found that yohimbine also objectively increased the rigidity of erections while sleeping. [12] Yohimbine appears to alleviate both physical and psychological symptoms associated with ED.

MEDLINE is the U.S. National Library of Medicine's (NLM) premier bibliographic database that contains over 18 million references to journal articles in life sciences with a concentration on biomedicine. A distinctive feature of MEDLINE is that the records are indexed with NLM Medical Subject Headings (MeSH).The great majority of journals are selected for MEDLINE based on the recommendation of the Literature Selection Technical Review Committee (LSTRC), a National Institute of Health (NIH)-chartered advisory committee of external experts analogous to the committees that review NIH grant applications. MEDLINE is the primary component of PubMed, part of the entry series of databases provided by the NLM National Center for Biotechnology Information (NCBI). MEDLINE may also be searched via the NLM Gateway (23).

b) Men With Digestive Disorders.  There are many, many GI disorders that plague modern, urban dwellers:  atrophic gastritis, Crohn's, diverticulitis, enzyme deficiencies, IBS, ulcerative colities and on and on.  All of these can lower vitamin and mineral absoprtion.  Men struggling with these issues may very well benefit from increased amounts of niacin in the diet or possibly with supplementation.

Erectile dysfunction can occur as a side effect of medication taken for another health condition. Common culprits are high blood pressure meds, antidepressants, some diuretics, beta-blockers, heart medication, cholesterol meds, antipsychotic drugs, hormone drugs, corticosteroids, chemotherapy, and medication for male pattern baldness, among others.


A study in the Journal of Sexual Medicine found that a large percentage of men with ED also have low levels of vitamin D. If you’re experiencing ED, you may want to have your level of vitamin D checked. Other symptoms of a low vitamin D level may be too subtle to notice. However, if you have serious vitamin D deficiency, you may have bone pain or muscle weakness. Vitamin D levels can be checked with a simple blood test and for most people corrected with a supplement.
Relevant publications were searched up to November 2010 in the MEDLINE (PubMed) database. The citation lists of randomized controlled trials on the effect of aerobic training and Erectile Dysfunction management using the International Index of Erectile Function (IIEF) as treatment outcome measure. Studies on different operative techniques on the effects of aerobic training for men with Erectile Dysfunction due to arterogenic Erecile Dysfunction were selected. Data on participants' characteristics, study quality, population, intervention, treatment outcome were collected and analyzed.
There have been only a few  well-controlled studies to test the effects of herbal yohimbe (as opposed to medications) on humans. There’s some evidence that yohimbine has potential to enhance the nitric oxide pathway, helping to bring blood flow to the corpus cavernosum tissue of the penis. It may also stimulate the pelvic nerve ganglia and boost adrenaline supply to nerve endings. It seems to have the most effects overall when combined with other treatments or herbal remedies. (6) One study that evaluated the effects of yohimbe on ED found that those taking the herbal remedy experienced slight benefits compared to a control group that was not taking the supplement.
Pay attention to your vascular health. High blood pressure, high blood sugar, high cholesterol, and high triglycerides can all damage arteries in the heart (causing heart attack), in the brain (causing stroke), and leading to the penis (causing ED). An expanding waistline also contributes. Check with your doctor to find out whether your vascular system — and thus your heart, brain, and penis — is in good shape or needs a tune-up through lifestyle changes and, if necessary, medications.
Nitric oxide is made internally from L-arginine, which is an amino acid found in red meat, poultry, fish, and dairy products. In other words, L-arginine is the building block for nitric oxide, which is essential for erections. A lack of one can lead to a lack of the other. However, there’s a problem when it comes to treating L-arginine deficiency with supplements.
