Many stores sell herbal supplements and health foods that claim to have sexual potency and fewer side effects. They’re also often cheaper than prescribed medications. But these options have little scientific research to back up the claims, and there’s no uniform method on testing their effectiveness. Most results from human trials rely on self-evaluation, which can be subjective and difficult to interpret.

ED can be caused by a handful of things, but one thing’s for sure: You need a healthy supply of the neurotransmitter nitric oxide (NO) to get and maintain an erection. NO is produced in nerve tissue and helps jolt your Johnson by relaxing the smooth muscle so blood can fill the penis. After the initial release of NO, your body releases a cascade of chemicals—including more of the neurotransmitter—to help keep you hard and happy, according to a study in the Proceedings of the National Academy of Sciences.
Some natural viagra supplements have been shown to increase nitric oxide levels and increase blood flow to the penis. But there are no true natural alternatives to prescription ED medication, like Viagra. But healthy food and (some) vitamins and supplements can improve your overall health and blood flow. And anything that improves blood flow can treat some of the causes of erectile dysfunction (as well as making you healthier).
According to legend, Casanova — the Tinder master of his time — regularly ate a breakfast of 50 oysters. Turns out he could’ve doubled as a nutritionist if he’d been able to get out of the sack. In addition to being high in B12, oysters contain more zinc than any other food source ( almost five times your daily DV). This nutrient is essential for testosterone production, and when your T levels droop, so does your business. Like other bivalves, oysters are high in D-aspartic acid, an amino acid that has been shown to temporarily boost low testosterone levels and improve sperm quality in infertile men.

With the advent of the “little blue pill” men’s sexual health has been thrust into the public eye and now, rather than worrying in embarrassed silence about “performance” issues, men are able to openly seek the help they need to function at their best. This is good news for the 30 million American men who suffer from erectile dysfunction or ED.1 And because 70 percent of ED cases are physiological in nature (it’s not just in your head) and often a sign of some other serious health issue, it is wise to address and correct the underlying physical imbalances that are hindering performance in the first place, ensuring both shortterm happiness and long-term health.
Wine – especially red wine – is a great source of the antioxidant phytochemical resveratrol, which helps open the arteries by enhancing the production of nitric oxide. Nitric oxide allows the blood vessels to expand, and this is how Viagra works. But while the little blue pill only works on tiny blood vessels, resveratrol helps your main arteries too. Make sure you stop at one or two glasses of wine – too much alcohol leads to the dreaded droop.
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.
