Sometimes low libido or sexual dysfunction can occur due to low testosterone levels. But that doesn’t necessarily mean you need a testosterone supplement. Your body usually can produce adequate testosterone, but it needs downtime to convert precursor hormones into testosterone. If you’re burning the candle at both ends, your body will convert those precursors into cortisol instead. So rest, relax, and allow your body to build up its testosterone stores.


Opioids are used for chronic pain or for recreational use, and there is currently   an epidemic of opioid addiction in the United States. Opioids induce ED by inhibiting gonado-tropin-releasing hormone (GnRH), which leads to a decrease in the production of luteinizing hormone (LH). Decreased levels of LH, in turn, inhibit production of testosterone, which – in both men and women – can cause depression and sexual dysfunction.9
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.
Erectile dysfunction (ED) is a common occurrence in society with a prevalence of about 26 cases per 1,000 patients [1]. This equates to about 150 million cases of ED worldwide. It is a condition where patients are unable to maintain adequate blood flow into their penis to sustain an erection. As a person ages, the probability of having ED grow but no age group is safe from this condition. In a study of Romanian men, it was determined that about 3 percent of males aged 15 to 25, 7 percent of males aged 25 to 45 and 22 percent of males 45 to 65 had ED [2]. Once a man reaches 70, ED can be seen in 84 percent of the elderly. In most cases, ED is a condition that manifests because of a much larger systemic disease. Some of the most common risk factors include cardiovascular disease, hypertension, diabetes mellitus, tobacco use, hyperlipidemia, metabolic syndrome or depression [3].

The lack of strong scientific proof that vitamin supplementation can improve erectile function doesn’t stop companies from selling vitamins, herbal supplements, and other products with the promise that they will do the job. ED is often treatable with prescription medications or medical procedures, so be careful not to get taken by a manufacturer’s empty promises.

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.
