HelloPharmacist Scorecard of DIM 150 by Woodstock Vitamins

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 Jul 11, 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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

DIM 150 contains 2 active ingredients: diindolylmethane (the acronym DIM) and TrueBoc. Diindolylmethane is a compound derived from cruciferous vegetables like broccoli and cabbage.

The product also contains several inactive ingredients — hydroxypropyl methylcellulose, stearic acid, magnesium stearate, silica, and microcrystalline cellulose — which are fillers and binders that help form and stabilize the capsule.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Diindolylmethane's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: estrogen metabolism and detoxification support.
  • We looked for evidence on: Premenstrual syndrome (PMS), Mastalgia, Breast cancer, Prostate cancer, Benign prostatic hyperplasia (BPH), Cervical dysplasia — and 4 related terms.
  • The closest evidence on file: Diindolylmethane is rated "Insufficient Reliable Evidence To Rate" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Diindolylmethane is rated "Insufficient Reliable Evidence To Rate" for Breast cancer, Colorectal cancer, Cervical dysplasia, Mastalgia, and more.

The effectiveness evidence for DIM 150 hasn't been established in the data we hold. Diindolylmethane has been studied for conditions including benign prostate enlargement, breast cancer, colorectal cancer, cervical dysplasia, and breast pain, but there is insufficient reliable evidence to rate how well it works for any of them.

We have no effectiveness data on file for TrueBoc.

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

A rare serious side effect called DRESS (drug rash with eosinophilia and systemic symptoms) has been reported. One case of stroke was reported in a patient taking diindolylmethane along with other supplements, though her increased stroke risk came from other medical conditions, making it unclear whether diindolylmethane played a role.

Because of possible effects on hormones and insufficient safety data, diindolylmethane is best avoided during pregnancy. There isn't enough safety information to use it while breastfeeding.

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.

Before you take DIM 150, check if you use any estrogen-containing medications like birth control pills or hormone replacement therapy — diindolylmethane may change how they work. Also flag any sodium-depleting water pills (diuretics) you take, and let your pharmacist know about any other medications you're on, since diindolylmethane may affect how certain drugs are broken down by your liver.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

DIM 150 is worth considering if you're interested in diindolylmethane and don't take estrogen-based medications, water pills, or drugs processed through CYP1A2. If you're on any prescription hormones, diuretics, or other medications, check them against our tool first.

Talk to your pharmacist or doctor before starting — especially if you're pregnant, breastfeeding, or have a history of stroke.

Diindolylmethane3 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 150 by Woodstock Vitamins: Common Questions

Does DIM 150 by Woodstock Vitamins interact with any medications?
Yes. Based on its ingredients, DIM 150 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 150 contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 150 if I'm pregnant or breastfeeding?
The data shows diindolylmethane is likely safe during pregnancy, so it's not off-limits — but because there's insufficient safety information for breastfeeding, it's best to avoid it while nursing. Talk with your doctor or pharmacist for personalized guidance based on your situation.
What side effects might I experience?
The most common ones are diarrhea, gas, headache, nausea, rash, and vomiting. A rare serious side effect called DRESS has been reported. Stop and contact your doctor if you develop a rash or other concerning symptoms.
Will DIM 150 help with breast cancer or prostate problems?
We don't have established evidence that it works for those conditions. Diindolylmethane has been studied for breast cancer, benign prostate enlargement, colorectal cancer, cervical dysplasia, and breast pain, but there's insufficient reliable evidence to rate its effectiveness for any of them.
How does diindolylmethane work?
Diindolylmethane is a compound found in cruciferous vegetables like broccoli and cabbage. It's theorized to have mild estrogenic or antiestrogenic properties, but the exact mechanisms aren't well established.
What is TrueBoc?
TrueBoc is the other active ingredient in this product, but we don't hold interaction or effectiveness data for it — your pharmacist may have additional information about this component.
