What happens when you take beetroot with vardenafil?
Beetroot and vardenafil both end up acting on the same blood vessel pathway, just from opposite ends. Beetroot raises the amount of nitric oxide your body makes, and vardenafil slows how fast that nitric oxide signal is switched off. Together they can relax blood vessels more than either does alone.
- Beetroot delivers dietary nitrate. Beetroot is one of the richest food sources of inorganic nitrate.
- Your body converts nitrate to nitric oxide. Bacteria in your mouth and gut reduce nitrate to nitrite, and your tissues convert nitrite into nitric oxide, the gas that relaxes vascular smooth muscle and gently lowers blood pressure.
- Vardenafil blocks PDE5. Vardenafil (Levitra, Staxyn) inhibits phosphodiesterase type 5, the enzyme that breaks down cyclic GMP. Nitric oxide does its work through cGMP, so blocking PDE5 amplifies and prolongs any nitric oxide vasodilation already happening.
- The effects stack. Combining a concentrated beetroot product with vardenafil increases nitric oxide production while slowing its breakdown signal, producing additive vasodilation and a somewhat deeper blood pressure dip than vardenafil alone.
Why is this important?
The hard contraindication on the vardenafil label is for organic nitrate drugs such as nitroglycerin and isosorbide. Cardiology guidance treats nitrates as off-limits around the time of a PDE5 inhibitor because the combination can cause a dangerously synergistic blood pressure drop.
Dietary nitrate from beetroot is not the same thing. The body handles it more slowly through the salivary nitrate-nitrite-nitric-oxide pathway, and it does not produce the rapid, intense nitric oxide surge that a nitrate drug does. That is why beetroot is not on the formal contraindication list, and why pharmacy guidance rates this combination as moderate rather than dangerous.
The reason it still deserves attention is that concentrated beetroot products are taken at amounts that meaningfully lower blood pressure on their own. If you take vardenafil along with a daily concentrated beetroot supplement, an alpha blocker for prostate symptoms, or other blood pressure medicines, the combined effect can leave you dizzy, lightheaded, or with a headache. Older men, people with autonomic neuropathy or a tendency to faint, and anyone who is dehydrated are more likely to feel it.
What should you do?
This is a manageable timing-and-disclosure issue, not a reason to give up beetroot.
- Before you change anything: if you eat beets occasionally in food, you do not need to adjust your habits. A roasted-beet salad or a few pickled slices delivers only a small fraction of the nitrate in a concentrated supplement. If you are thinking about starting a daily beetroot regimen and you already have low resting blood pressure or take other vasodilators, raise it with your prescriber first.
- On any day you take vardenafil: skip concentrated beetroot juice shots, beetroot powders, and nitrate-based pre-workout supplements. If you use these regularly, leave a clear gap so the beetroot is not stacking with the dose; a few hours apart is the principle, and same-day avoidance is simplest if you take vardenafil as needed.
- After your dose: if you feel lightheaded or get a strong headache, sit down, hydrate, and let it pass. Chest pain, prolonged fainting, or vision changes need urgent medical attention.
Tell your doctor or pharmacist about any regular beetroot supplement so they can watch for low blood pressure, especially if you also take blood-pressure or prostate medication.
Which specific products are affected?
On the medication side this applies to all vardenafil products, including Levitra, the orally disintegrating Staxyn, and generic vardenafil.
On the beetroot side, the products that matter are the concentrated ones: beetroot juice shots (Beet It, Love Beets, James White and similar), beetroot powder capsules and scoops marketed for nitric oxide or blood pressure, and pre-workout supplements built around beetroot extract or sodium nitrate. Whole-food beet servings — roasted beets, pickled slices, beet greens in a meal — are not the focus of this concern.
The science behind it
The mechanism is well established in human pharmacology. A pharmacology review of the nitrate plus PDE5-inhibitor interaction describes how nitric oxide raises cGMP while PDE5 inhibitors prevent its breakdown, which is the basis for keeping organic nitrate drugs and vardenafil apart (EBM Consult, pharmacology review).
That beetroot itself lowers blood pressure is also documented: a randomized, double-blind, placebo-controlled crossover study found that beetroot juice acutely reduced aortic systolic blood pressure by a few mmHg (PMC6369216). Pharmacy interaction guidance brings the two together and rates beetroot extract plus PDE5 inhibitors as a moderate, additive blood-pressure interaction (Bolt Pharmacy).
What is missing is direct evidence: there are no published case reports of beetroot plus vardenafil causing harm. The concern is mechanism-based and supported by the proven blood-pressure effects of each component, which is why moderate is the honest rating — real enough to plan around, not a documented emergency.
Frequently Asked Questions
Is beetroot as dangerous with vardenafil as nitroglycerin?
No. Nitroglycerin and other organic nitrate drugs are a hard contraindication because they cause a rapid, intense nitric oxide surge. Dietary beetroot acts slowly and gently and is rated only a moderate interaction.
Can I still eat beets in my normal meals?
Yes. Whole-food portions of beets deliver a small fraction of the nitrate in a concentrated supplement and do not require any timing changes around vardenafil.
What about a daily beetroot supplement for blood pressure?
That is the situation to discuss with your prescriber, because the supplement is already lowering your blood pressure and vardenafil can add to it. Disclosure matters most if you also take other blood-pressure or prostate medicines.
How long should I separate a beetroot shot from vardenafil?
Keep them a few hours apart at minimum, and if you take vardenafil as needed, simply skip the beetroot shot on that day. Vardenafil's effect is relatively short-lived, so most of the overlap risk is the same day as your dose.
What symptoms should make me stop and rest?
Dizziness, lightheadedness, or a strong headache after combining the two. Sit down and hydrate. Chest pain, fainting that does not pass, or vision changes are reasons to seek urgent care.
Does this apply to other ED drugs too?
The same nitric-oxide mechanism applies to sildenafil and tadalafil, so the same principle — avoid concentrated beetroot products around your dose — is a reasonable precaution with any PDE5 inhibitor.
Key takeaways
- Beetroot and vardenafil act on the same nitric-oxide pathway, so concentrated beetroot products can add to vardenafil's blood-pressure lowering.
- This is a moderate, mechanism-based interaction — not the hard contraindication that applies to nitrate drugs like nitroglycerin.
- Whole-food beet portions are fine; the concern is beetroot juice shots, powders, and nitrate pre-workouts.
- On a day you take vardenafil, skip concentrated beetroot products or keep them a few hours apart.
- Tell your doctor or pharmacist about any daily beetroot supplement, especially alongside other blood-pressure or prostate medicines.
- Sit and hydrate if you feel lightheaded; seek urgent care for chest pain, prolonged fainting, or vision changes.
