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.
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).
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.
In addition, when research has shown a nutrient such as zinc or niacin to improve sexual function, it's usually in people who are deficient in it. So, before you stock up on over-the-counter nutritional supplements for ED, speak with your doctor. He can test you for deficiencies and steer you toward the most effective and safest way to treat your erectile dysfunction. 

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.

It’s easy to see how erectile dysfunction subsides with exercise. Not only does it help reduce cardiovascular risk factors, but it’s also been shown to reduce stress, another cause of the condition. The best part is that it doesn’t take much effort to get started on an exercise routine. “When it comes to exercise, there is no one-size-fits-all approach,” co-author Dr. Stephen Freedland said in the release. “However, we are confident that even some degree of exercise, even if it’s less intense, is better than no exercise at all.”
A yohimbine HCL dosage of 0.2 milligrams per kilogram of bodyweight taken on an empty stomach immediately upon waking or in-between meals ramps up fat oxidation without causing undesirable side effects like high blood pressure or racing heart. [3] The table below provides a guideline on how many 2.5mg capsules of yohimbine HCL you should take based on your weight and the recommended dosage:

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.


There’s some concern that supplements labeled as yohimbe contain different amounts of the active ingredient than the amount that’s listed. The FDA strictly regulates prescriptions containing yohimbine but not supplements. It can be difficult to determine exactly how much active yohimbine is in supplements due to how different growing and distributing variables affect the concentration. These variables can include: the exact type of yohimbe tree bark that is used, what part of the tree the bark is taken from, the maturity of the tree, how fresh the bark is, the processing techniques used to create supplements, and how the supplements are shipped/exported and stored. (16)
In addition, when research has shown a nutrient such as zinc or niacin to improve sexual function, it's usually in people who are deficient in it. So, before you stock up on over-the-counter nutritional supplements for ED, speak with your doctor. He can test you for deficiencies and steer you toward the most effective and safest way to treat your erectile dysfunction. 
Suggested intake: “The problem with yohimbine is that you can’t regulate the amount in a dosage,” says Fratellone. “It all depends on what part of the tree it comes from, how it’s cultivated, how it’s exported, and so on. The amount of extract you get will vary.” FDA researchers analyzed a number of over-the-counter yohimbe bark products. They found that the supplements contained only seven percent or less of the amount of yohimbine that would be found in actual yohimbe bark, which suggests that they contained little or no yohimbe. However, the prescription form of yohimbine is strictly regulated by the FDA. It is approved only for the treatment of impotence, and is available in tablets and capsules. For erectile dysfunction, 5.4 to 10 milligrams three times daily has been studied and regarded as generally safe.
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.
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.
Dealing with erection problems can be a challenge. However, there are lots of treatments and lifestyle changes which can help. While medications such as Viagra improve symptoms in the short term, pelvic floor exercises can help you improve your sexual function in the long term. Find out why pelvic floor, also known as Kegel exercises, can be used to treat ED and how to perform the exercises correctly.
While eating magnesium-rich foods or taking a magnesium supplement at the proper dosage is safe for most men, the mineral can interfere or interact with some medications. Discuss the benefits and risks of altering your daily magnesium intake with your doctor, particularly if you take blood pressure medications, diuretics, diabetes medications or antibiotics. Men diagnosed with erectile dysfunction often require changes in other minerals and vitamins or even prescription medication. Ensuring a proper daily intake of magnesium may help maintain healthy erectile function, but magnesium alone is unlikely to cause a significant reduction in ED symptoms. Magnesium levels can also be affected by excess weight, chronic stress and excessive amounts of alcohol. These factors may also be partially responsible for erectile problems.
In a 2005 study, three months of twice-daily sets of kegel exercises combined with biofeedback and advice on lifestyle changes, such as quitting smoking, losing weight, and limiting alcohol, worked far better than just giving the participants advice. “Wearing tight pants will affect impotence along with some other medical conditions like diabetes and heart disease,” which can also affect a man’s degree of impotence, Dr. Jennifer Burns, specializing in family practice with an emphasis on gastrointestinal health at the BienEtre Center, told Medical Daily.
In rare cases, the drug Viagra ® can cause blue-green shading to vision that lasts for a short time. In rare cases, the drug Cialis® can cause or increase back pain or aching muscles in the back. In most cases, the side effects are linked to PDE5 inhibitor effects on other tissues in the body, meaning they are working to increase blood flow to your penis and at the same time impacting other vascular tissues in your body. These are not ‘allergic reactions'.
Though higher doses of zinc reduce libido, supplementation with a medium dose (5 mg/day) has some beneficial effect on the sexual competence of adult male rats. The major significant effects of this dose of zinc are prolongation of ejaculatory latency without disturbing sexual arousability, motivation, penile erection and sex vigor. Also, the partner preference index of the 5 mg/day group was positive and comparable to the controls. A positive partner preference index is indicative of unchanged sexual interest of males.[16] These results confirmed that libido and sexual interest are not affected by zinc supplementation with a 5 mg/day dose. However, mild reduction in percentage of intromission was observed in this group and it is postulated that this may be situational rather than an effect of supplemented zinc. This is based on our observation where mild rejection by the females at the initial phase of the behavior led some males to refrain from sexual activity.
In addition to getting helpful nutrients from your diet, you can also consider supplementing. Many of these are also on my list of top five supplements to increase sex drive, so they’re helpful for overall sexual health. It’s a good idea to check in with a practitioner, particularly one with knowledge of your individual health issues and medications, before taking anything. Here are some I recommend:
Erectile dysfunction (ED) is commonly called impotence. It’s a condition in which a man can’t achieve or maintain an erection during sexual performance. Symptoms may also include reduced sexual desire or libido. Your doctor is likely to diagnose you with ED if the condition lasts for more than a few weeks or months. ED affects as many as 30 million men in the United States.
A 2011 study of 160 men with moderate or severe erectile dysfunction divided the group in two—80 men were given niacin supplements, and 80 a placebo. The group given niacin reported improved ability to “maintain an erection versus the control group.” It’s not exhaustive research, but still promising. The best part about niacin is that it’s naturally found in foods like turkey, avocado, and peanuts (yum). If you’re not a turkey sandwich fan, you can supplement with a vitamin B complex.
