The 7 Best Foods for Better Sex, According to Research

The internet is full of tips and tricks claiming they can spice up a lackluster sex life. But if you're fueling yourself with frozen pizza, donuts, and beer, you're not setting the stage for any of them to work.

Research on more than 21,000 men found that a diet rich in vegetables, fruits, nuts, beans, and fish, and low in red and processed meats, was linked to a lower risk of developing erectile problems. In other words, the better you eat, the better your odds in the bedroom.

Below, we'll cover how diet affects your erections, the type of diet with the best evidence, and seven foods worth adding to your plate, plus what each one can (and can't) do.

• A healthy diet supports the blood flow, energy, and hormone balance good sex depends on.
• Seven foods with research behind them: watermelon, dark chocolate, coffee, red onions, pumpkin seeds, pomegranate juice, and beets.
• Most work through flavonoids, nitrates, or other compounds that help blood vessels relax.
• None of them work like ED medication. They support erectile health over time.
• Cut back on greasy meals, heavy drinking, and processed snacks.

Food is fuel. It affects your mood, fitness, energy, and, not surprisingly, your sex life. Putting high-quality gas in the tank is a surefire way to run at your best.

Erections depend on healthy blood vessels that can relax and let blood flow in, a process driven by nitric oxide. It's the core of how erections happen. Diets heavy in saturated fat and processed foods raise the risk of obesity, diabetes, high blood pressure, and high cholesterol, some of the leading causes of erectile problems. Even one fast food meal can temporarily affect how your blood vessels work.

Poor nutrition also drains your energy. Diets high in processed foods and added sugar are linked to lower energy levels, and fatigue doesn't do your stamina any favors.

The best diet for your sex life is rich in vegetables, fruits, nuts, beans, healthy fats, fish, and lean proteins. The Mediterranean diet checks every box and has the most research behind it.

Keeping your plate colorful helps too. Flavonoids, plant compounds found in many fruits, vegetables, and even drinks like tea, are a big part of why. A study of more than 25,000 men found those who ate the most flavonoid-rich foods had a lower risk of developing ED.

Low levels of certain nutrients, including vitamin B12, folic acid, and vitamin D, have also been linked to erection problems.

1. Watermelon

Watermelon is one of the best natural sources of L-citrulline, an amino acid your body turns into nitric oxide. In a small study of men with mild ED, 50% reported firmer erections after a month of L-citrulline supplements, compared with about 8% on placebo. You'd need a lot of watermelon to match those doses, but it's a hydrating, erection-friendly snack.

2. Dark Chocolate

Deliciously sweet and seductive, dark chocolate has some of the best science of any "sex food." A meta-analysis of 42 trials found chocolate and cocoa improved blood vessel function and slightly lowered blood pressure. Go for 70% cocoa or higher and keep it to about an ounce.

3. Coffee

We all know coffee wakes up your brain, but it might help other parts of your body too. In a large U.S. study, men who drank about 2–3 cups of coffee a day were less likely to report ED than men who drank little or none. Caffeine may help relax blood vessels, though most of the mechanism research is in animals. Skip the sugary coffee drinks.

4. Red Onions

Onions won't win you any points for fresh breath, but they've been called an aphrodisiac for centuries, and red onions are packed with flavonoids. In a 2016 analysis, red onions had about three times the flavonoids of yellow onions, and white onions had almost none. Red onions are also rich in anthocyanins, one of the flavonoid types most strongly linked to lower ED risk.

What about testosterone? A 2019 review found most studies showed onion juice or extract raised testosterone, but almost all were in rats. Only one small study tested men, using a concentrated extract. So onions are a great flavonoid source, but don't count on them as a testosterone booster. Add raw red onion to salads, salsas, and sandwiches for the most benefit.

5. Pumpkin Seeds

Pumpkin seeds are loaded with zinc, magnesium, and L-arginine. Zinc supports normal testosterone, and L-arginine helps your body make nitric oxide. A rat study found pumpkin seed diets improved markers tied to erectile function, and pumpkin seed preparations have been studied for prostate health in men. Sprinkle them on salads or keep a stash for snacking.

6. Pomegranate Juice

Pomegranate juice is loaded with antioxidants, about three times more than red wine or green tea. In rats, it helped improve erectile function by reducing oxidative stress, and one small study reported higher salivary testosterone and better mood after drinking it. Watch the sugar, and go for 100% juice.

7. Beets

Beets are popular with athletes for on-field performance and might help with performance in the bedroom too. They're one of the most nitrate-rich vegetables, and your body converts nitrates into nitric oxide, the molecule behind healthy blood flow and erections. Not a fan of raw beets? Try them roasted, or go for beet juice. Celery and leafy greens are nitrate-rich too.

Red wine's antioxidants have been studied for heart health and erectile function, and a glass with dinner is fine for most people. But more isn't better. Heavy drinking makes erections harder to get and keep, so keep it to a drink or two.

• Heavy, greasy meals, especially right before sex
• Fast food and processed snacks like chips and cookies
• Sugary sodas and drinks
• More than a drink or two of alcohol

These can leave you sluggish in the moment and, over time, raise the risk of heart disease and other conditions linked to erection problems.

What you eat plays a real role in how you perform in the bedroom. Filling your plate with flavonoid- and nitrate-rich foods supports blood flow, energy, and heart health. Plus, a colorful plate isn't just Instagram-worthy; it's good for your sex life.

Swap greasy fast food for these foods and pair them with regular exercise and good sleep, and you'll be giving your body the best shot. These are some of the most reliable natural ways to get stronger erections.

And if you need more than diet can deliver, prescription ED medication is far more reliable. In clinical trials, 67–89% of men taking PDE5 inhibitors had improved erections. BlueChew offers sildenafil, tadalafil, and vardenafil, the active ingredients in Viagra, Cialis, and Levitra, as sublingual tablets that typically start working within 15–30 minutes. See how the seven formulas compare.

Can what I eat affect my sex life?

Yes. A diet rich in vegetables, fruits, nuts, beans, and fish supports the blood flow and heart health erections depend on, and is linked to a lower risk of ED. Processed and high-fat foods do the opposite over time.

What foods help erections?

Foods rich in flavonoids and nitrates have the most research behind them: watermelon, dark chocolate, red onions, berries, pomegranate, and beets and leafy greens. Pumpkin seeds add zinc and L-arginine.

What are the benefits of onions for men?

Red onions are one of the richest sources of flavonoids, which are linked to a lower risk of ED. Rat studies suggest onion juice may raise testosterone, but that hasn't been confirmed in men eating onions. They support erectile health as part of a healthy diet, not as a treatment.

What foods should I avoid before sex?

Skip heavy, greasy meals, a lot of alcohol, and sugary or processed snacks. They can leave you sluggish and bloated, and over time they're linked to conditions that cause erection problems.

Is coffee good for erections?

It might help. Men who drank about 2–3 cups a day were less likely to report ED in a large U.S. study. Caffeine may help relax blood vessels.

Can food replace ED medication?

No. These foods support erectile health over time, but prescription PDE5 inhibitors are far more effective for treating ED. Many men find combining a healthy diet with treatment works best.
