HelloPharmacist Scorecard of Sprouted Broccoli Seed 400 mg by Swanson GreenFoods Formulas

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 11, 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: 400 mg of organic sprouted broccoli. Sprouted broccoli is broccoli seed that has been allowed to germinate, concentrating its nutrients.

The remaining ingredients are inactive — pullulan (a plant-based capsule material), organic rice concentrate, organic rice extract, organic sunflower oil, and de-oiled sunflower lecithin — used to fill the capsule and improve absorption.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Phytonutrient-rich green foods.
  • We looked for evidence on: Bladder cancer, Breast cancer, Colorectal cancer, Gastric cancer, Prostate cancer, Hypercholesterolemia — and 4 related terms.
  • The strongest evidence on file: Broccoli is rated "Possibly Effective" for Colorectal cancer (Natural Medicines).
  • Also on file: Broccoli is rated "Insufficient Reliable Evidence To Rate" for Bladder cancer, Breast cancer, Gastric cancer, Hypercholesterolemia, and more.

Broccoli is possibly effective for reducing colorectal cancer risk. For bladder cancer, breast cancer, fibromyalgia, and gastric cancer, the evidence in our data is insufficient — we don't have enough reliable evidence to say whether it works or doesn't.

If you're considering this supplement for any of these conditions, talk with your doctor or pharmacist about what the research actually supports.

The evidence, ingredient by ingredient Broccoli

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.

Broccoli as food is well tolerated in normal amounts, but concentrated supplements like this one are less studied. The facts note caution with concentrated extracts unless your doctor approves.

Some people taking broccoli seed or sprout extracts have reported loose stools, diarrhea, stomach pain, and cramping, especially at higher doses. Topically, allergic reactions causing contact dermatitis have occurred, though that's less relevant to a capsule.

Broccoli is rated Likely Safe in pregnancy and lactation.

Why this rating?

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This supplement is a concentrated form of broccoli, and while broccoli as food is fine, concentrated extracts are less well studied. The main concern is that it may make certain medications less effective by speeding up how your liver processes them.

If you take any prescription drugs — especially those metabolized by CYP1A2 or CYP2A6 enzymes — check them against the interaction tool before starting. Talk with your pharmacist about whether this product is right for you.

Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP1A2.
Pharmacokinetic research in humans shows that eating 500 grams of fresh broccoli daily for 6-12 days can increase CYP1A2 activity by 10% to 200%. Induction of CYP1A2 activity by broccoli is attributed to its glucosinolate constituents.

Likelihood Possible Evidence B
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP2A6.
Pharmacokinetic research in humans shows that eating 500 grams of broccoli daily for 6 days increases CYP2A6 activity by 135% to 550%. Induction of CYP2A6 activity is attributed to its glucosinolate constituents.

Sprouted Broccoli Seed 400 mg by Swanson GreenFoods Formulas: Common Questions

Does Sprouted Broccoli Seed 400 mg by Swanson GreenFoods Formulas interact with any medications?
Yes. Based on its ingredients, Sprouted Broccoli Seed 400 mg has a known interaction with 187 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Sprouted Broccoli Seed 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.
Is this safe to take while pregnant or breastfeeding?
Broccoli is rated Likely Safe in pregnancy and lactation. That said, concentrated supplements are less studied than broccoli as food. If you're pregnant or nursing, it's worth checking with your doctor or pharmacist for personalized advice.
Can I take this if I'm on medication?
It depends on what you take. Broccoli can speed up how your liver processes certain drugs — particularly those broken down by two liver enzymes called CYP1A2 and CYP2A6 — which might make them less effective. Use the medication checker on this page to see if any of your prescriptions are affected.
What side effects might I experience?
Some people report loose stools, diarrhea, stomach pain, and cramping from broccoli seed extracts, especially at higher doses. Start with the recommended amount and see how you feel. If you have digestive issues, talk to your pharmacist.
Does this really help prevent cancer?
The evidence is limited. Broccoli is possibly effective for colorectal cancer risk. For bladder cancer, breast cancer, gastric cancer, and fibromyalgia, we don't have enough reliable evidence to say whether it works. Your doctor can discuss whether it's worth trying alongside your regular care.
Is this the same as eating broccoli?
No. This is a concentrated extract of sprouted broccoli seed. Broccoli as food is safe and well tolerated in normal amounts, but concentrated supplements are less studied. That's why caution is recommended unless your doctor approves it.
What are the inactive ingredients?
The capsule is made of pullulan, a plant-based material. The other inactive ingredients are organic rice concentrate, organic rice extract, organic sunflower oil, and de-oiled sunflower lecithin — they help fill and stabilize the capsule.
