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

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: Broccoli Flower Bud Extract at 500 mg per serving. It also includes dextrin, an inactive ingredient used as a filler in the 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 Broccoli's overall clinical evidence instead.

Moderate

Some clinical evidence supports Broccoli 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: Colorectal cancer — rated "Possibly Effective" (Natural Medicines).

Broccoli extract is possibly effective for reducing colorectal cancer risk based on available evidence. For bladder cancer, breast cancer, fibromyalgia, and gastric cancer, the evidence we hold is insufficient to rate it—that doesn't mean it doesn't work, just that reliable studies aren't yet in our data.

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 a food is well tolerated by most people, but this is a concentrated supplement and is less studied. The safety data advises caution—concentrated broccoli extracts should be used only with your doctor's approval.

Reported side effects include loose stools, diarrhea, abdominal pain, and stomach cramping, especially at higher doses. Allergic contact reactions have also been reported when applied to skin.

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.

Broccoli extract may appeal to you if you're interested in colorectal cancer prevention support, but the concentrated form carries more uncertainty than eating fresh broccoli. Be careful if you take medications that rely on liver enzymes to work—this supplement can speed up how your body clears them.

Talk with your pharmacist before starting, especially if you're on any prescription drugs.

Broccoli Flower Bud Extract2 drug types · 187 drugs

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.

Broccoli Extract Powder 500 mg by BulkSupplements.com: Common Questions

Does Broccoli Extract Powder 500 mg by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, Broccoli Extract Powder 500 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?
Broccoli Extract Powder 500 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 this work for cancer prevention?
Broccoli extract is possibly effective for colorectal cancer based on what we know. For breast, bladder, and gastric cancers, the evidence isn't strong enough yet to say. Talk with your doctor about whether it fits your health plan.
What does broccoli extract do in my body?
It contains glucosinolates, compounds that can speed up how your liver breaks down certain medications. That's why we need to check your other drugs before you use it.
Can I take it while pregnant or breastfeeding?
Broccoli extract is rated likely safe during pregnancy and lactation based on available data, but because this is a concentrated supplement and safety evidence is limited, it's wise to talk with your doctor or midwife first.
What are the side effects?
Loose stools, diarrhea, stomach pain, and cramping have been reported, especially at higher doses. Allergic skin reactions are also possible when broccoli comes into contact with skin.
Is this just powdered broccoli?
No—this is a concentrated extract of broccoli flower buds, which is more potent than eating fresh broccoli. That's why it needs more caution and your doctor's sign-off.
