Celery doesn't usually make the "sexy foods" list. It's crunchy, watery, and mostly famous for being on the side of your wings. But it has a surprising claim to fame: celery is one of the most nitrate-rich vegetables you can eat, right up there with beets and spinach. Your body turns those nitrates into nitric oxide, the molecule that helps blood vessels relax, which is exactly what erections depend on.

That said, no study has tested whether eating celery improves erections. Here's what celery can and can't do for men, from erections to testosterone and sperm health.

• Celery is classified as a "very high" nitrate vegetable, alongside beets, spinach, lettuce, and arugula.
• Your body converts dietary nitrates into nitric oxide, which helps blood vessels widen and can lower blood pressure.
• Diets rich in vegetables and flavonoid-rich foods are linked to lower ED risk.
• Claims that celery boosts testosterone or sperm come from rodent studies with mixed results; it hasn't been tested in men.
• Celery's natural nitrates can lower blood pressure slightly, so tell your provider if you eat a lot of it and take blood pressure or ED medication.

Celery is about 95% water, but the rest packs a few compounds worth knowing about:

• Dietary nitrates: the headline act, converted by your body into nitric oxide
• Apigenin and luteolin: flavonoids with antioxidant effects
• 3-n-butylphthalide: a compound behind celery's aroma that's been studied for blood pressure effects
• Potassium, vitamin K, and folate: nutrients that support heart and blood vessel health

And it's about 15 calories a cup, so it's easy to eat a lot of without thinking twice.

How Nitrates Become Nitric Oxide

When you eat nitrate-rich vegetables, bacteria in your mouth convert the nitrates to nitrites. Your body then turns those into nitric oxide, which signals blood vessels to relax and widen. That same molecule kicks off how erections happen when you're aroused.

ED medications work further down the same pathway. PDE5 inhibitors like sildenafil keep blood vessels relaxed longer by blocking the enzyme that ends an erection. Celery helps supply the starting signal; the medication keeps it going. That's why the medication's effect is much stronger.

The takeaway: celery's nitrates genuinely support healthy blood flow and blood pressure, which matters for erections. But it's a supporting player in a healthy diet, not a treatment.

This is the most common celery question guys ask, so let's be straight: there's no good evidence that eating celery raises testosterone in men.

The claims come from rodent studies using concentrated celery extracts, and the results are all over the place. One rat study found that a celery extract raised testosterone, and a mouse study of celery seed extract reported higher testosterone and sperm counts at certain doses. But another rat study found that a celery seed extract did the opposite, lowering testosterone and sperm counts at high doses. Researchers have also pointed out that some of these studies contradict each other.

None of these used the amount of celery a person would actually eat, and none were in humans. If you think your testosterone is low, a blood test is the way to find out. Things like sleep, exercise, and a healthy weight have far more evidence behind them.

Maybe, but again, the research is limited to animals. Celery contains antioxidants like apigenin and vitamin C, and sperm are sensitive to oxidative damage. In a rat study, celery leaf extract improved sperm production and some fertility measures.

The flip side: the rat study on celery seed extract found it reduced sperm count and motility and lowered fertility at high doses. So celery as a normal food is fine, but concentrated celery seed supplements aren't a fertility booster, and may not be a good idea if you're trying to conceive.

If you and your partner are trying for a baby and have concerns, a provider can check for common, treatable causes of male infertility.

Celery seed is sold as a spice and as a supplement, often marketed for blood pressure or men's health. As a seasoning, it's safe. As a concentrated supplement, there's no human evidence it helps erections or testosterone, and the animal research on fertility is mixed. Talk to a provider before taking celery seed supplements, especially if you take blood pressure medication, blood thinners, or diuretics.

Both deliver nitrates, since nitrates dissolve in water.

• Raw stalks keep the fiber, which helps with digestion and blood sugar. Dip them in hummus or peanut butter for a filling snack.
• Celery juice packs more celery into one serving but loses the fiber. If you juice at home, keep some pulp in.
• Mix it up: add celery to soups, stir-fries, salads, and smoothies alongside other nitrate-rich vegetables like spinach, arugula, and beets.

There's no established amount or timing for sexual health. Eating plenty of vegetables consistently matters more than downing celery juice before a date.

Celery is safe for most people. A few things to keep in mind:

• Bloating or gas can happen if you suddenly eat a lot. Start slow.
• Allergies: skip celery if you're allergic to it. People with birch pollen allergies sometimes react to it too.
• Blood thinners: celery contains some vitamin K, so if you take warfarin, keep your intake consistent.
• Blood pressure and ED medications: celery's nitrates can lower blood pressure slightly. If you eat a lot of it or drink celery juice daily, let your provider know.
• Kidney issues: watch your potassium intake from all sources.

Note that dietary nitrates from vegetables are different from nitrate medications for chest pain, like nitroglycerin. Those should never be taken with ED medication.

Celery works best as one part of a healthy routine:

• Eat a heart-healthy diet. A Mediterranean-style diet is linked to lower rates of ED. Pair celery with foods like watermelon, dark chocolate, and pumpkin seeds, and cut back on fast food.
• Move more. Aerobic and pelvic floor exercises support blood flow.
• Sleep and manage stress. Good sleep supports testosterone, and chronic stress gets in the way of arousal.
• Don't smoke, and limit alcohol. Smoking damages blood vessels, and heavy drinking makes erections harder to get.

Together, these are the most reliable natural ways to get stronger erections.

About 30 million men in the U.S. have erectile dysfunction. If erection problems happen often, celery won't fix them, and ED can be an early warning sign of heart disease, so it's worth talking to a provider.

Prescription PDE5 inhibitors are the most effective treatment for most men. In clinical trials, 67–89% of men taking them had improved erections. BlueChew offers sildenafil, tadalafil, and vardenafil, the active ingredients in Viagra, Cialis, and Levitra. All formulas are sublingual tablets that typically start working within 15–30 minutes, except DailyTAD, which is chewable.

• SIL: 45 mg sildenafil, lasts about 4–6 hours
• VAR: 8 mg vardenafil, lasts about 4–6 hours
• TAD: 9 mg tadalafil, lasts up to 36 hours
• MAX and VMAX: two-ingredient combinations that last up to 36 hours
• GOLD: sildenafil, tadalafil, apomorphine, and oxytocin
• DailyTAD: 9 mg tadalafil plus 7 essential vitamins, taken daily

You don't have to choose between healthy habits and treatment. Many men find combining the two works best.

Is celery good for erections?

Celery is one of the most nitrate-rich vegetables, and your body turns nitrates into nitric oxide, which helps blood vessels relax. That supports healthy blood flow, but no study has shown celery improves erections directly.

Is celery juice good for erectile dysfunction?

Celery juice delivers nitrates and may help lower blood pressure slightly, but it hasn't been tested as an ED treatment. Prescription medications like sildenafil and tadalafil improved erections in 67–89% of men in clinical trials.

Does celery increase testosterone?

There's no good human evidence that it does. Rodent studies using concentrated celery extracts have mixed results: some found higher testosterone, and one found celery seed extract lowered it at high doses.

How long does it take for celery to help?

Nitrates raise nitric oxide within a few hours of eating, but the long-term blood vessel benefits of a vegetable-rich diet build over weeks and months.

Can I eat celery if I take ED medication?

Yes, in normal food amounts. Celery's natural nitrates can lower blood pressure slightly, so if you eat a lot of it or drink celery juice daily, let your provider know. Dietary nitrates are different from nitrate medications like nitroglycerin, which should never be taken with ED medication.

Can celery replace Viagra?

No. Celery supports the starting signal for erections, but sildenafil, the active ingredient in Viagra, works much more directly and powerfully.

Is celery good for sperm?

It might help in normal food amounts, thanks to its antioxidants, but the evidence comes from rat studies, not men. One study found concentrated celery seed extract actually lowered sperm count at high doses.

Is celery water good for men?

Celery water (celery steeped or blended with water) is a low-calorie, hydrating drink that provides some nitrates and antioxidants. There's no evidence it has specific benefits for men's sexual health beyond what eating celery provides.
