What is this page for?

First and foremost: how Beet interacts with medications. The heart of this page is the interaction list — every drug Beet is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Beet is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

Beet Drug Interactions: The Bottom Line

From the HelloPharmacist Editorial Team · Updated July 2026

Based on the available evidence, the overall risk of a clinically significant Beet drug interaction appears low for most people. None of beet's interactions are rated major, and the moderate ratings rest on lab research rather than effects proven in people.

Interactions deserving the most attention

The biggest group is CYP3A4 substrates, medications cleared by a particular liver enzyme; a beet pigment blocked this enzyme in lab tests, so beet could in theory raise levels of these drugs, but this has not been shown in humans. With blood pressure medications, beet's natural nitrates can relax blood vessels, though human studies are mixed and one found concentrated beetroot juice did not meaningfully change blood pressure or heart rate. People whose blood pressure medicine is closely adjusted are the ones for whom even a small added effect could matter.

What the rest of the list means

Beet's long list of interacting medications reflects a few shared mechanisms applied across many drugs, not hundreds of separate proven problems. Most entries are theoretical, based on possible effects on enzymes the body uses to process medications, and the best human data so far has not shown clinically meaningful changes.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

The big picture

The kinds of drugs Beet affects

Every type of medication (drug category) Beet is known to interact with. Open any category for the detail — or search your exact drug in the checker above.

All 3 drug categories Beet interacts with

Cytochrome P450 3a4 (cyp3a4) SubstratesAntihypertensive DrugsCytochrome P450 1a2 (cyp1a2) Substrates

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.

Likelihood Possible Evidence D

Antihypertensive Drugs

Beet and beetroot contain nitrates, which can cause vasodilation, potentially leading to lower blood pressure. However, a study published in the European Journal of Clinical Nutrition using concentrated beetroot juice found no significant impact on blood pressure or heart rate in different age groups. Other small clinical studies suggest that while beet consumption might transiently lower blood pressure due to vessel dilation, there's no consistent evidence of a lasting effect. Overall, the theoretical risk of reduced blood pressure due to beet's nitrate content exists, but studies generally indicate a low and temporary impact rather than a sustained decrease.

Likelihood Possible Evidence A

Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, beet might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research suggests that beet induces CYP1A2 enzymes.

Beet: Uses, Safety & Side Effects

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Reviewed July 2026 ·

The bottom line

Beet, especially beetroot juice, is a nitrate-rich food that may modestly lower blood pressure and slightly improve exercise performance in some people. It is generally safe as a food, but supplement effects are modest and not a substitute for prescribed treatment, so talk with your pharmacist or doctor before relying on it.

Scientific name: Beta vulgaris
Family: Amaranthaceae
Part used: Root and leaves (greens)
Common forms: Juice, powder, capsules, tablets, whole food, concentrated shots, gels

People commonly use it for

High blood pressure
Exercise and athletic performance
Heart and circulation support
General antioxidant/anti-inflammatory support
Liver and digestive support

Popular and traditional uses — not proof it works. See “Uses & effectiveness” below for the evidence.

Safety at a glance

OverallLikely safe

Beet is widely eaten as a food and is generally well tolerated for most adults.

PregnancyUse caution

Beet as a food is fine, but concentrated supplements lack safety data, so use caution.

BreastfeedingInsufficient reliable information

There is insufficient reliable information available about the safety of beets used medicinally during pregnancy and breast-feeding.

Overview

Beet (Beta vulgaris) is a root vegetable that has been eaten for centuries and is grown in many parts of the world. The deep-red beetroot is the most familiar form, but the leafy green tops are also edible and nutritious. Beets are related to chard and spinach.

As a supplement, beet is most often sold as beetroot juice or beetroot powder, sometimes standardized by its nitrate content. People take it hoping to support healthy blood pressure, improve exercise performance, and provide antioxidants. It is also a popular natural food coloring.

How it works

Beets are rich in dietary nitrate. In the body, nitrate can be converted into nitric oxide, a molecule that helps relax and widen blood vessels. This may improve blood flow and slightly lower blood pressure, and it may help muscles use oxygen more efficiently during exercise.

Beets also contain betalains (the pigments that give them their red or yellow color), along with vitamins, minerals, and other plant compounds that have antioxidant properties in laboratory studies. Much of the detail about how these compounds work in people is still being studied.
