HelloPharmacist Scorecard of BroccoCap by Intensive Nutrition

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

BroccoCap contains three active ingredients: sulforaphane, broccoli, and daikon. Sulforaphane is a compound from broccoli thought to support cellular health.

Broccoli itself is included for its nutrients and bioactive compounds, and daikon is a radish used in traditional wellness practices. The product also contains dried broccoli, daikon, and magnesium stearate as inactive ingredients (fillers and binders that help form the capsule).

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 its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients 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 ingredients' overall clinical evidence instead.
  • On file: Prostate cancer — rated "Possibly Effective" (Sulforaphane) (Natural Medicines).
  • On file: Colorectal cancer — rated "Possibly Effective" (Broccoli) (Natural Medicines).

The evidence for BroccoCap's ingredients is mixed and often limited. Sulforaphane is possibly effective for prostate cancer support, but the data is insufficient to rate it for hay fever, asthma, or general cancer.

Broccoli is possibly effective for colorectal cancer, but evidence is insufficient for bladder cancer, breast cancer, fibromyalgia, and gastric cancer. Daikon has insufficient evidence for both biliary disorders and diabetes support.

None of these ingredients has strong, well-established proof for the uses you might be considering, so talk with your doctor about what the current research supports for your specific needs.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Sulforaphane from food is considered safe, but this product contains a concentrated supplement form, which is less studied for long-term use. The most common side effects reported are bowel discomfort, heartburn, stomach upset, and vomiting.

Isolated cases have noted headache, insomnia, irritability, increased weight gain, and in rare instances seizure in people with autism or seizure history. Broccoli and daikon as foods are generally well tolerated, though concentrated supplements of either are less established.

At high doses, broccoli extract can cause loose stools, diarrhea, abdominal pain, and cramping. Daikon may cause throat tightness, hives, or mild indigestion in rare cases.

Pregnancy and lactation: sulforaphane supplements are not proven safe in pregnancy—stick to normal food amounts. The data for daikon doesn't include a pregnancy safety rating, so there isn't enough information to know either way; broccoli as food is considered likely safe in pregnancy.

For breastfeeding, there's not enough information on supplement-level sulforaphane doses, so use caution and prefer dietary amounts.

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?
  • 3 of the 3 matched ingredients can interact with medications — Radish, Sulforaphane, Broccoli.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 804 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 BroccoCap, double-check with your doctor or pharmacist if you take any medications metabolized by liver enzymes CYP3A4, CYP1A2, CYP2E1, or CYP2A6 (sulforaphane and broccoli can affect how your body clears these drugs), diabetes medications (daikon may lower blood sugar), or any blood thinners or other drugs you depend on to stay at a steady level in your bloodstream. These are Moderate-severity interactions based on the lab and human evidence we have.

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.

BroccoCap might appeal to someone interested in sulforaphane and cruciferous vegetable support, but the evidence for most of its purported uses is insufficient or mixed. If you take any prescription medication—especially drugs metabolized by your liver's cytochrome P450 enzymes, diabetes medications, or blood thinners—you should check with your doctor or pharmacist before starting, since the interaction potential is real and broad.

Pregnant people should avoid the concentrated sulforaphane in this product and stick to broccoli as food instead.

Each ingredient & the kinds of drugs it affects

For each ingredient in BroccoCap with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Sulforaphane3 drug types · 722 drugs

Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, sulforaphane might alter the levels and clinical effects of CYP1A2 substrates.
Animal and in vitro research shows that sulforaphane inhibits CYP1A2 enzyme activity. However, its precursor glucoraphanin also appears to increase the expression of the CYP1A2 enzyme, which could lead to increased metabolism of CYP1A2 substrates. These effects have not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, sulforaphane might increase the levels and effects of CYP2E1 substrates.
In vitro evidence shows that sulforaphane inhibits CYP2E1 enzymes. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, sulforaphane might increase the levels and effects of CYP3A4 substrates.
Animal and in vitro research shows that sulforaphane inhibits CYP3A4 enzyme activity and downregulates its expression. This interaction has not been reported in humans.

Likelihood Possible Evidence D

Broccoli2 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.

Likelihood Possible Evidence B

Daikon1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, radish might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that radish extract, juice, and sprouts can reduce glucose levels. Animal research also shows that radish root juice 300 mg/kg reduces fasting and postprandial blood glucose in a rat model of diabetes, with effects similar to glibenclamide.

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.
Can I take BroccoCap if I'm pregnant?
Concentrated sulforaphane supplements haven't been proven safe in pregnancy, so you should avoid this product and stick to eating broccoli as normal food instead. Talk with your doctor for personalized advice on what's best for you.
What are the most common side effects?
The most common are bowel discomfort, heartburn, stomach upset, and vomiting. At higher doses, you might also experience loose stools, diarrhea, or abdominal cramping. Rare cases have reported headache, insomnia, and increased weight gain.
Does BroccoCap actually work for cancer?
Sulforaphane is possibly effective for prostate cancer, and broccoli is possibly effective for colorectal cancer, but the evidence is limited. For most other cancers, there isn't enough reliable evidence to rate it. Talk with your oncologist about whether it fits into your care plan.
Is there any ingredient in here with no known drug interactions?
No—all three active ingredients (sulforaphane, broccoli, and daikon) have documented interactions with certain medication types. If you're on prescription drugs, check your exact medications against the tool on this page before you start.
Can I take BroccoCap while breastfeeding?
There isn't enough information on supplement-level sulforaphane doses while breastfeeding, so use caution. Broccoli as food is generally fine. Talk with your doctor or pharmacist to decide what works best for you and your baby.
