HelloPharmacist Scorecard of Beet Root 550 mg by NOW Sports

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: beet root powder at 550 mg per capsule. Beet root is the dehydrated, powdered form of the beet vegetable and is the sole medicinal component here.

The capsule also contains inactive ingredients — rice flour, hypromellose (the capsule material itself), stearic acid, and silicon dioxide — which are excipients that help form and fill the capsule.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Immune support and general health.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for beet root is mixed. It's rated Possibly Effective for athletic performance and for exercise-induced muscle soreness — that is, some clinical data supports its use for these purposes, though the evidence isn't conclusive.

For chronic obstructive pulmonary disease (COPD), it's rated Possibly Ineffective. For cholesterol and cognitive function, there isn't enough reliable evidence in our data to say whether it works.

The evidence, ingredient by ingredient Beet

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Beet root is widely eaten as a food and is generally well tolerated for most adults. However, concentrated supplements like this one lack the safety data that food does, so use caution if you're new to supplementing with beet.

The most common side effects are harmless — red urine and red stools, which reflects the beet's color and isn't cause for concern. In rare cases, large amounts have been reported to cause low blood calcium (hypocalcemia) and kidney damage.

One case report noted black stools after taking beet pills, though the patient had no serious bleeding. If you see unusual stool color or any concerning symptoms, stop and contact your doctor.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Beet.
  • The most serious interaction on file is rated Moderate.
  • For scale: 862 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, check whether you take any medications broken down by your liver using the CYP3A4 enzyme — this is a large and diverse group (the interaction spans 850 medications), and beet root may raise their levels. Also double-check if you're on blood pressure medications or drugs processed through the CYP1A2 enzyme.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Beet root may help athletic performance or exercise recovery, though the evidence is modest. It's generally well tolerated, but the Moderate-severity interaction with a large group of liver-metabolized drugs means you should check your medications before you start.

Talk to your pharmacist if you're on prescription drugs, especially anything for heart rhythm, mental health, or cholesterol.

Beet root powder3 drug types · 861 drugs

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 Root 550 mg by NOW Sports: Common Questions

Does Beet Root 550 mg by NOW Sports interact with any medications?
Yes. Based on its ingredients, Beet Root 550 mg has a known interaction with 861 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Beet Root 550 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will beet root turn my pee and poop red?
Yes, it's one of the most common effects — your urine and stools may turn red because beet root is brightly pigmented. This is harmless and nothing to worry about. In some cases, people have also reported black stools.
Does beet root actually improve athletic performance?
It's rated Possibly Effective based on clinical evidence, meaning some studies support it for athletic performance and exercise-induced muscle soreness, but the evidence isn't overwhelming. Whether it'll help you personally depends on your individual response.
Is beet root safe if I eat beets as a vegetable anyway?
Beet as a food is fine and well tolerated. But this is a concentrated supplement, and we don't have as much safety data on supplements compared to food, so use caution — especially if you're taking medications that interact with it.
Can I take this while pregnant or breastfeeding?
The safety data on file doesn't cover pregnancy or breastfeeding. Talk with your doctor or pharmacist about whether this supplement is right for you in either situation, because we can't give personalized advice here.
What are the serious side effects I should watch for?
Serious effects are rare, but large amounts can theoretically cause low blood calcium or kidney damage. If you notice unusual symptoms, stop taking it and contact your doctor. Also watch for any signs of gastrointestinal bleeding if you're on blood thinners.
