In fact, one common reason many younger men visit their doctor is to get erectile dysfunction medication. Often, men with erectile dysfunction suffer with diabetes or heart disease, or may be sedentary or obese, but they don’t realize the impact of these health conditions on sexual function. Along with erectile dysfunction treatment, the doctor may recommend managing the illness, being more physically active, or losing weight.
These results are remarkable, because it appears that not only can niacin improve short term erectile function in many men, but also can likely help to reverse arterial plaque if a comprehensive program is undertaken.  Of course, neither I nor anyone else knows how safe megadosed niacin is long term, but many experts consider it safe when used under the care of a knowledgeable physician.  You'll have to do your own due diligence.

Eggs a supplement? Yup. Testosterone is derived from cholesterol, and eggs are the healthiest way to ensure you’re getting enough of the good kind (LDL cholesterol). Plus, eggs are rich in choline, a powerful natural chemical that not only burns fat but can help set your pants afire. Choline triggers the production of nitric oxide (NO), which relaxes arteries in the penis and enables blood flow to do its thing. Choline is a precursor to acetylcholine, a neurotransmitter which controls sexual behavior through its activity in the brain; having a higher level of AcH has been associated with more frequent sex and more intense, longer orgasms. And that’s not all: Check out these things that happen to your body when you eat eggs!
[notice color=’#ebebeb’]Vitamin B2 (riboflavin) takes an active part in the production of certain hormones and erythrocytes and in the synthesis of ATP, a so-called life fuel. In addition, it protects the human retina from excessive exposure to UV radiation, ensures the dark adaptation of the human eye, increases visual acuity and perception of colour and light. Riboflavin is needed for tissue growth and tissue regeneration.[/notice]

You may know horny goat weed from its omnipresence behind the counter at your local convenience store, but this traditional Chinese formula is less sketchy than it sounds. Used for centuries to treat low libido and erectile dysfunction, the herb’s potential efficacy was show in a 2010 study published in the Journal of Sexual Medicine. Researchers who fed the supplement to rats found they had improved erectile function; another study showed that the supplement can block a natural chemical that wilts erections. (Just be warned: Viagra was found to be 80 times more powerful.)
It’s hard to concentrate on what’s happening in the bedroom when you’re thinking about problems at work. For many men, it’s psychological issues like anxiety rather than physical ones that contribute to E.D. Chronic stress has also been linked to heart disease, high blood pressure, depression, and more. Find a way of blowing off steam that works for you (I like exercise and meditation) and stick to it.
Yohimbe supplements often list yohimbe bark extract or yohimbine as the active ingredient. However, some of these products might not provide accurate information about the amount of yohimbine in the supplement. Also, some yohimbe supplements list yohimbine hydrochloride as an active ingredient. Yohimbe products containing man-made yohimbine hydrochloride as an ingredient are not legal to sell as a dietary supplement in the US.
Aside from pelvic floor exercises, it has been found out that aerobic exercises also work in treating erectile dysfunction. This condition is often caused by problems related to blood flow to the penis. Diabetes, obesity, vascular disease as well as high cholesterol may affect blood flow. This results to erectile dysfunction. By adding some aerobic exercises to your routine, you can significantly enhance your overall male sexual health and may even remove the problem totally in the long run.
While the rationale behind why it would work is airtight, the research on arginine’s actual effect on erectile dysfunction is slim, points out Charles Walker, M.D., assistant professor of urology and cofounder of the Cardiovascular and Sexual Health clinic at Yale University. But given its solid safety profile, minimal side effects, and potential benefit on heart disease, it’s worth a try, he adds, especially when taken in conjunction with other herbs on this list, which studies have shown can be more effective.

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.
I am so grateful Jacqui, I am seeing my girlfriend tomorrow and feel like the problem is pretty much gone! I can't believe it I thought I was broken!!! I have searched on sooo many sites and got so much bad advice and feel like posting the link of your site on all of those others. As this is a horrible problem and your method will work for me - so guys need to know this! Many, many thanks for the help.
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.
Lastly, it should be remembered that many individuals without dyslipidemia take niacin as a preventative measure. If you plan to take more than about 800 mg of niacin a day, it is a good idea to have your liver tested periodically just to make sure that your liver has no problem with high-dose niacin. These liver tests are the same used to check for liver toxicity in people taking statins, from which there is a higher likelihood of liver toxicity compared to taking niacin. The principal problem from taking statins is muscle damage which is serious enough to be life-threatening. This problem does not occur with those who take niacin. Not to be forgotten, niacin has been found to prolong orgasm.
You've probably heard of the old saying "use it or lose it". Your sex muscles are just like any other muscles. If you're not using them regularly (masturbation doesn't count) they will lose size and strength. This commonly happens as you age. Considering most people judge a healthy sex life to be 3-5 times per week, that's not a lot of use for these important muscle groups. Therefore, it's best to exercise the muscles which support a healthy sex life so you can enjoy sex well into your 80's.

A daily dose of niacin improves erectile function, particularly in men with high cholesterol, according to a 2011 study in The Journal of Sexual Medicine. The vitamin helps increase blood flow and reduce inflammation—one of the underlying causes of both high cholesterol and erectile dysfunction. “Vitamin B3 is also used to make sex hormones and other important chemical-signal molecules,” says Fisch. Like many of the others on our list, this tablet is most powerful when taken in conjunction with others: A cocktail of propionyl, L-carnitine, L-arginine, and niacin taken for three months improved 40% of erections in a study from researchers at Sapienza University of Rome in Italy.
It's also important to remember that your mental health plays as much a part of your sexual ability as your physical health. Stress and other mental health concerns can cause or make erectile dysfunction worse. Minor health problems may slow your sexual response, but the accompanying anxiety that comes with the slow sexual response can shut things down entirely.
Yohimbine hydrochloride is the principal alkaloid of the bark of the African yohimbe tree. It is primarily selective for the presynaptic alpha-2 receptor that enhances the central release of norepinephrine1,2 or even epinephrine,3 although the latter is controversial.4 This central action increases sexual arousal2,5 and appears similar to the central alpha-2 adrenergic mechanism that initiates hot flashes.6 Peripherally, yohimbine may partially antagonize norepinephrine-induced contraction of corporeal cavernosal smooth muscle.7,8 The action is that of an antagonist to postjunctional alpha-2 adrenergic receptors, but a direct effect on vascular smooth muscle is also possible.9

Some medications are changed and broken down by the liver. Yohimbe might decrease how quickly the liver breaks down some medications. Taking yohimbe along with some medications that are broken down by the liver can increase the effects and side effects of some medications. Before taking yohimbe talk to your healthcare provider if you take any medications that are changed by the liver.

Reduction of the libido index was the major disadvantage that we observed with zinc supplementation. Substances that affect libido usually act centrally and may reduce desire by causing sedation or hormonal disturbances.[17] The role of elevated levels of PRL in serum as an inhibitor of sexual drive and gonadal function is well established.[18] This reduction of sex drive may occur through the modification of activity of dopaminergic neurons in the CNS that are regarded as controlling sexual motivation and function.[19] Our study demonstrated a significant increase of serum PRL level (2.9 to 7.22 ng/dl) within two weeks of supplementation of zinc (5 mg/day). This is a possible explanation for the reduced libido with increasing doses of zinc observed in this study.

Moreover, it has a positive effect on the nervous system, liver, skin, and mucous membranes, as well as keeps skin, nails, and hair healthy. And of course, what is important for men, erectile dysfunction treatment with vitamin B2 relieves symptoms of the most hateful male disease. Moreover, this vitamin is well-known as a supplier of sexual energy and vitality.


In the analysis of the study, the niacin group showed a significant increase in both IIEF-Q3 scores and IIEF-Q4 scores compared to the initial baseline values. While the placebo group also showed a significant increase in IIEF-Q3 scores (high hopes, no doubt), it did not for IIEF-Q4 scores. In other words, the “placebo effect” did not extend to maintaining erections. Also, when patients were stratified according to the baseline severity of ED, the patients with moderate and severe ED who received niacin showed a significant improvement in IIEF-Q3 scores (0.56 and 1.03, respectively) and IIEF-Q4 scores (0.56 and 0.84, respectively) compared with baseline values. These results were not significantly increased for the placebo group.

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]


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.

On the other hand, high zinc levels have negative effects on sperm quality. Excessive zinc intake in mice have indicated a negative effect of increasing doses of zinc on sperm count and motility.[5] Although there have been studies focusing on various aspects of zinc related reproductive functions, studies on zinc related sexual behavioral aspects have received scant attention. In one study, intranasal irrigation with zinc sulphate has been reported to completely abolish the sexual behavior of male rats.[6]
