HelloPharmacist Scorecard of DIM 200 mg Capsules by BulkSupplements.com

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 Oct 1, 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: diindolylmethane (DIM), a compound derived from cruciferous vegetables like broccoli and cabbage. The capsule itself is made from bovine gelatin, which is an inactive ingredient (filler).

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Diindolylmethane product and its label doesn't state a use — see Diindolylmethane's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for diindolylmethane isn't established yet. Our data shows insufficient reliable evidence to rate it for benign prostatic hyperplasia (enlarged prostate), breast cancer, colorectal cancer, cervical dysplasia (abnormal cervical cells), or mastalgia (breast pain).

That doesn't mean it doesn't work — it means the science simply isn't there to confirm one way or the other.

The evidence, ingredient by ingredient Diindolylmethane

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.

Diindolylmethane is generally well tolerated in short-term studies, but long-term safety hasn't been studied well. The most common side effects are diarrhea, gas, headache, nausea, rash, and vomiting.

A rare serious side effect — drug rash with eosinophilia and systemic symptoms (DRESS) — has been reported. One case of stroke was reported in a woman taking 200 mg daily alongside other supplements, but she had significant stroke risk factors, so it's unclear if DIM played a role.

During pregnancy, the safety data rates this as likely safe. However, there isn't enough safety data for breastfeeding, so it's best avoided while nursing.

If you're pregnant or breastfeeding, talk with your doctor or pharmacist about whether this is 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 — Diindolylmethane.
  • The most serious interaction on file is rated Moderate.
  • For scale: 269 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 start, double-check with your doctor or pharmacist if you take estrogens (birth control, hormone therapy), water pills (diuretics), or any medications broken down by the liver enzyme CYP1A2. These are the main medication types with documented interactions.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

DIM might interest you if you're exploring natural options for certain health concerns, but the evidence for its effectiveness isn't solid yet. If you take hormone therapy, water pills, or medications sensitive to liver metabolism, you'll want to check with your doctor or pharmacist first — interactions are possible.

Long-term safety data is thin, so this isn't something to take indefinitely without a good reason.

Diindolymethane3 drug types · 269 drugs

Diuretic Drugs

Theoretically, diindolylmethane might increase the risk of hyponatremia if used with sodium-depleting diuretics.
Large doses of diindolylmethane (600 mg daily) have been associated with two cases of asymptomatic hyponatremia in clinical research.

Likelihood Possible Evidence B
Estrogens

Theoretically, diindolylmethane might increase or decrease the effects of estrogens.
Diindolylmethane might have mild estrogenic or antiestrogenic effects. Theoretically, large amounts of diindolylmethane might interfere with hormone replacement therapy.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, diindolylmethane might lower serum levels of CYP1A2 substrates.
In vitro evidence suggests that diindolylmethane can induce CYP1A2. Theoretically, it might increase metabolism of CYP1A2 substrates and lower serum concentrations. This interaction has not been reported in humans.

DIM 200 mg Capsules by BulkSupplements.com: Common Questions

Does DIM 200 mg Capsules by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, DIM 200 mg Capsules has a known interaction with 269 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
DIM 200 mg Capsules 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.
Can I take this while I'm on birth control or hormone therapy?
Not without checking first. Diindolylmethane might increase or decrease how your body responds to hormonal medications, and large doses could interfere with hormone therapy. Talk with your doctor or pharmacist — they may want to watch your hormone levels or adjust your dose.
What are the most common side effects?
Diarrhea, gas, headache, nausea, rash, and vomiting are the most common. Most people tolerate it well, but these digestive and headache symptoms can happen.
Is this safe to take while breastfeeding?
There isn't enough safety data to know, so it's best avoided while nursing. Talk with your doctor or pharmacist about what's right for you.
Does DIM actually work for prostate health or cancer prevention?
We don't have enough reliable evidence to say it works for those uses. That's not a 'no' — it's a 'we don't know yet' based on current research.
Is it safe to take long-term?
Long-term safety hasn't been well studied. It's generally well tolerated in short-term research, but we don't have solid data on what happens if you take it for months or years.
