HelloPharmacist Scorecard of Full Spectrum Beet Leaf 400 mg by Swanson Premium Brand

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 30, 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 leaf at 400 mg per capsule. The capsule itself is made with gelatin, rice flour, magnesium stearate, and silica — inactive ingredients that help deliver the beet powder.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Beet's overall clinical evidence instead.

Moderate

Some clinical evidence supports Beet for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Athletic performance — rated "Possibly Effective" (Natural Medicines).
  • On file: Exercise-induced muscle soreness — rated "Possibly Effective" (Natural Medicines).

Beet shows possibly effective evidence for athletic performance and exercise-induced muscle soreness. The data on its use for chronic obstructive pulmonary disease (COPD) points to possibly ineffective.

For cholesterol management (dyslipidemia) and brain function (cognitive function), we don't have reliable evidence yet to rate 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 eaten as a food is widely consumed and generally well tolerated by most adults. When it comes to concentrated supplements like this one, safety data is limited, so use caution.

Short-term use of beet for medicinal purposes appears well tolerated overall. The most common side effect is red-colored stools and urine — harmless and temporary.

Rarely, black stools have been reported. In very large amounts, beet theoretically could lower calcium levels (hypocalcemia) or cause kidney damage, though these are uncommon.

There isn't enough data on file regarding safety during breastfeeding — talk with your doctor or pharmacist about whether this product is right for you if you're nursing.

Side effects, ingredient by ingredient Beet

Meds to double-check

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 drugs broken down by the liver enzyme CYP3A4 — beet may raise their levels (Moderate severity). Also confirm you're not on blood pressure medications, since beet's nitrate content could theoretically lower pressure further (Minor).

If you take CYP1A2 substrates, those levels might decrease (Minor). Your pharmacist can look up your exact medications.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

If you're an athlete or recovering from exercise soreness and want to try beet for possibly effective support, this is a reasonable option. Because it can affect how your liver processes over 800 medications, you must check your exact prescriptions against the interaction tool before you start.

Talk with your doctor or pharmacist about whether the potential benefits outweigh any risks for your situation, especially if you take blood pressure or heart medications.

Beet3 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.

Full Spectrum Beet Leaf 400 mg by Swanson Premium Brand: Common Questions

Does Full Spectrum Beet Leaf 400 mg by Swanson Premium Brand interact with any medications?
Yes. Based on its ingredients, Full Spectrum Beet Leaf 400 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?
Full Spectrum Beet Leaf 400 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.
Does beet really help with athletic performance?
Research suggests it's possibly effective for athletic performance and for reducing soreness after exercise. The evidence isn't overwhelming, but beet has enough clinical support to be worth trying if you're interested.
Why might my stools turn red or black after taking this?
Red coloring is the most common side effect and is harmless — it's just beet pigment passing through. Black stools have also been reported rarely. Neither means anything is wrong, but if you're on blood thinners and see black stools, mention it to your doctor to rule out bleeding.
Is concentrated beet supplement as safe as eating beets?
Beet as food is generally well tolerated, but concentrated supplements don't have the same safety track record. Use caution with this form, and stick to short-term use unless your doctor advises otherwise.
Can I take this if I'm on blood pressure medicine?
Beet contains nitrates that can relax blood vessels and lower pressure. While a clinical study of beetroot juice showed no major effect, the theoretical risk is there — check with your doctor or pharmacist before combining it with blood pressure drugs.
What should I do if I take a lot of medications?
Use the medication interaction checker on this page to search each of your prescriptions. Because beet affects how your liver processes over 860 medications, it's especially important to confirm your specific drugs are safe to combine with it.
Is this safe to take while breastfeeding?
We don't have enough safety data on concentrated beet supplements during breastfeeding. Talk with your doctor or pharmacist about whether this product is right for you if you're nursing.
