According to the FDA (Food and Drug Administration), many of these products sold on the internet contain potentially harmful compounds. And they aren’t listed on the label. In an investigation, the FDA found that one-third of these online supplements were laced with undisclosed ingredients. This includes sildenafil—the active ingredient in Viagra. Doctors prescribe Viagra to some patients, but it’s not safe for everyone. The drug could interact with other medications and lower your blood pressure to dangerous levels. This makes ordering supplements online risky. You don’t know whether they contain sildenafil or other ingredients that could harm your health.

A cold slice of watermelon can do more than just satisfy thirst and hunger during the warm summer months; it can help with bedroom satisfaction. Citrulline, the amino acid found in high concentrations of watermelon, is found to improve blood flow to the penis. A 2011 study revealed men who suffered from mild to moderate ED and took L-citrulline supplementation showed an improvement with their erectile function and were very satisfied. Natural watermelon juice, or “nature’s Viagra,” can also be easier on the stomach, since taking pills like Viagra can cause nausea and diarrhea.
When considering vitamin supplementation for erectile dysfunction, one of the first vitamins that you may come across in literature would be Vitamin D. This is a vitamin that can be easily obtained through many types of dairy products like milk, cheese, and yogurt and is also in abundance if you live in a tropical climate. Sunlight is able to give us a natural dose of vitamin D daily. [6] Although vitamin D is usually associated with improving bone strength and prevention osteoporosis, another valuable feat of vitamin D is the fact that it helps reduce atherosclerosis. Studies confirm that there is a similar underlying mechanism that occurs between conditions like cardiovascular disease and erectile dysfunction. As blood vessels are damaged and filled with plaques, the diameter for blood to flow through is gradually reduced. After a few years, the amount of blood may be reduced substantially. Vitamin D is able to help activate cells that remove some of these dangerous plaques and delay the onset of ED. [7]
To understand the physiology of erectile dysfunction, we need to know erection first. An erection occurs when impulses from the brain and genital nerves cause blood to fill the two chambers known as the corpora cavernosa in the male penis. This causes the penis to expand and stiffen. Anything that blocks these impulses or restricts blood flow to the penis can result in ED. This block may be caused by psychological, neurologic, hormonal, arterial, or cavernosal impairment or even from a combination of all these factors.3
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.
