HelloPharmacist Scorecard of Broccoli Sprout 450 mg 4:1 Extract by TerraVita Premium Collection

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.

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 supplement contains one active ingredient: a 4:1 concentrated extract of broccoli sprouts, providing 450 mg per capsule. Broccoli sprouts are young broccoli plants harvested within days of germination and are rich in compounds called glucosinolates, which your body converts into sulforaphane and related chemicals.

The extract is made inactive ingredients: gelatin (the capsule) and water.

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).

The data we hold shows that broccoli extract is possibly effective for colorectal cancer prevention. For bladder cancer, breast cancer, fibromyalgia, and gastric cancer, the evidence is insufficient—we don't have enough reliable data to say whether it works or not.

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

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 in normal amounts is well tolerated. However, concentrated supplements like this extract are less studied, and safety data isn't well established for them.

The main side effects reported in studies are digestive: loose stools, diarrhea, abdominal pain, and cramping, especially at higher doses. Allergic skin reactions (contact dermatitis) have occurred with topical broccoli exposure but are uncommon.

Because the safety of this concentrated extract isn't certain, talk with your doctor before starting it—they can help you decide if it's right for you.

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 — Broccoli.
  • The most serious interaction on file is rated Moderate.
  • For scale: 187 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 you take this supplement, double-check any medications that are broken down by the liver enzymes CYP2A6 or CYP1A2—broccoli extract can speed up how fast your body clears these drugs, potentially making them less effective. This is a moderate-severity interaction affecting a large number of medications.

Your doctor or pharmacist can look up your specific drugs to see if any fall into these categories.

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 sprout extract may interest you if you're looking at colorectal cancer prevention and want a food-based option, but be aware it interacts with a large number of medications by speeding up how your liver breaks them down. If you take any prescription drugs—especially for smoking cessation, blood pressure, pain, or cancer treatment—you need to check with your doctor or pharmacist before starting this supplement.

Digestive side effects like cramping and diarrhea can occur, particularly at higher doses.

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 Sprout 450 mg 4:1 Extract by TerraVita Premium Collection: Common Questions

Does Broccoli Sprout 450 mg 4:1 Extract by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Broccoli Sprout 450 mg 4:1 Extract 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 Sprout 450 mg 4:1 Extract 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.
What exactly is broccoli sprout extract?
It's a concentrated form of young broccoli plants (sprouts) harvested just days after germination. This product is a 4:1 extract, meaning it's condensed to be more potent than the sprouts alone. It's rich in glucosinolates, compounds your body converts into sulforaphane.
Does broccoli sprout extract actually prevent cancer?
The data we have shows it's possibly effective for colorectal cancer. For bladder, breast, and gastric cancers, and fibromyalgia, the evidence isn't solid enough yet to say whether it works. Talk with your doctor about what the research actually supports for your specific concern.
Will this supplement make my other medications less effective?
Yes, it can. Broccoli extract speeds up two liver enzymes that break down many medications, potentially lowering their blood levels. It affects 187 individual drugs across different categories. Before starting, have your doctor or pharmacist check whether any of your prescriptions are on that list.
What side effects should I watch for?
Digestive upset is most common: loose stools, diarrhea, abdominal pain, and cramping, especially at higher doses. Allergic skin reactions are rare. If you have a sensitive stomach, start low and see how you tolerate it, and tell your doctor if symptoms don't settle.
Is this safe during pregnancy or while breastfeeding?
Broccoli extract is rated likely safe during pregnancy and lactation. That said, concentrated extracts aren't as well studied as broccoli food itself, so check with your doctor or pharmacist before taking it if you're pregnant or nursing.
