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

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 found naturally in cruciferous vegetables like broccoli and cabbage. The capsule itself is made from bovine gelatin.

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 in the data we hold. We have insufficient reliable evidence to rate it for benign prostatic hyperplasia, breast cancer, colorectal cancer, cervical dysplasia, or breast pain — which are the main uses studied.

That doesn't mean it doesn't work; it means the research to prove it hasn't been nailed down yet.

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, though long-term safety isn't well established. The most common side effects are diarrhea, gas, headache, nausea, rash, and vomiting.

A rare but serious rash with systemic symptoms (DRESS) has been reported. One case of stroke was reported in a patient taking DIM along with several other supplements, but the patient had multiple stroke risk factors, so it's unclear whether DIM played a role.

Because of possible effects on hormones and lack of long-term safety data, DIM is best avoided during breastfeeding — there isn't enough safety information. For pregnancy, the data rates it likely safe, but that's limited information overall.

Side effects, ingredient by ingredient Diindolylmethane

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.

Check with your pharmacist if you take birth control pills or hormone replacement therapy — diindolylmethane might change how your body handles estrogens. Also flag sodium-depleting diuretics (water pills) and any medications processed by your liver's CYP1A2 enzyme system.

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 appeal to someone looking into prostate or cancer health, but the evidence to support those uses isn't solid yet. If you take birth control, hormone replacement therapy, or water pills, you need to talk with your pharmacist or doctor first — this supplement could interfere with how they work.

Long-term safety is still a question mark.

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 DIM if I'm pregnant?
The safety data rates diindolylmethane as likely safe in pregnancy, but the evidence is limited. It's still a good idea to talk with your doctor or pharmacist before starting — they can weigh what you've heard against your personal health picture.
Can I take DIM while breastfeeding?
No reliable safety information exists for breastfeeding, so it's best to avoid it. Talk with your doctor if you're considering it.
What are the side effects?
Most common are diarrhea, gas, headache, nausea, rash, and vomiting. Serious side effects are rare but can include a severe rash (DRESS). Stop and call your doctor if you develop a rash.
Does DIM actually work for prostate health or cancer prevention?
We don't have enough reliable evidence yet to say whether it works for those uses. The studies haven't been conclusive enough to make that claim.
Why does this product interact with so many medications?
One ingredient alone can affect how your liver processes multiple different drugs — that's why the count is high. It doesn't mean you can't take it; it just means you need to check your specific medications before you start.
