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.

Estrohalt contains three active ingredients. Diindolylmethane and indole-3-carbinol are compounds derived from cruciferous vegetables like broccoli and cabbage.

Flaxseed oil powder complex is a plant-based source of omega-3 fatty acids and other compounds. The product also includes inactive ingredients—microcrystalline cellulose, dicalcium phosphate, stearic acid, croscarmellose sodium, magnesium stearate, silicon dioxide, and pharmaceutical glaze—which serve as binders, fillers, and coating.

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.

Why this rating?
  • The label markets this product for: Estrogen and hormone balance support.
  • We looked for evidence on: Breast cancer, Cervical dysplasia, Endometrial hyperplasia, Mastalgia, Ovarian cancer, Polycystic ovary syndrome (PCOS) — and 4 related terms.
  • The closest evidence on file: Flaxseed Oil is rated "Insufficient Reliable Evidence To Rate" for Breast cancer (Natural Medicines).
  • Also on file: Flaxseed Oil is rated "Insufficient Reliable Evidence To Rate" for Endometrial hyperplasia, Mastalgia, Polycystic ovary syndrome (PCOS), Prostate cancer.
  • Also on file: Indole-3-carbinol is rated "Insufficient Reliable Evidence To Rate" for Breast cancer, Cervical dysplasia.

The evidence we hold doesn't establish that any of these ingredients work reliably for their proposed uses. Diindolylmethane and indole-3-carbinol have insufficient evidence for breast cancer, colorectal cancer, cervical dysplasia, and other conditions.

Flaxseed oil is rated possibly ineffective for obesity, rheumatoid arthritis, bipolar disorder, and high cholesterol. That doesn't mean they don't work—it means the data we have isn't strong enough to confirm benefit yet.

The evidence, ingredient by ingredient Diindolylmethane Indole-3-carbinol Flaxseed Oil

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.

Diindolylmethane and indole-3-carbinol are generally well tolerated in short-term use, but long-term safety isn't established. Common side effects from both include diarrhea, nausea, headache, gas, and rash.

Indole-3-carbinol at higher doses has caused unsteadiness, tremor, and imbalance in some people. Flaxseed oil is generally well tolerated; at high doses (30 grams daily or more) it may cause loose stools or diarrhea.

A small number of people report dry mouth or stomach upset at around 5 grams daily. Severe allergic reactions to flaxseed oil are rare.

Neither diindolylmethane nor indole-3-carbinol has reliable safety data for pregnancy or breastfeeding—the safety notes advise against them in these situations. Flaxseed oil has no rating on file for pregnancy; there's limited safety data for breastfeeding, so medical advice is recommended if you're nursing.

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 — Flaxseed Oil, Indole-3-carbinol, Diindolylmethane.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 464 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 your medications carefully before taking this product. Avoid it with anticoagulant or antiplatelet drugs (blood thinners like warfarin or aspirin)—both indole-3-carbinol and flaxseed oil increase bleeding risk.

If you take estrogen therapy, birth control, water pills, blood pressure medications, or ezetimibe (Zetia), discuss this product with your pharmacist first. Diindolylmethane and indole-3-carbinol may also affect how your liver processes certain medications.

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.

This product targets hormone-related health concerns, but the evidence for its ingredients isn't strong yet. If you take any blood thinners, birth control, hormone therapy, blood pressure medication, or the cholesterol drug Zetia, you need to check with your pharmacist before starting—interactions are documented.

Long-term safety isn't well established, so talk with your doctor or pharmacist about whether it's right for you.

Indole-3-Carbinol3 drug types · 294 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, indole-3-carbinol might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
In vitro research shows that indole-3-carbinol inhibits platelet aggregation.

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

Theoretically, indole-3-carbinol might increase the metabolism of CYP1A2 substrates and lower serum concentrations.
Animal research shows that indole-3-carbinol induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Estrogens

Indole-3-carbinol might interfere with the effects of estrogen therapy.
Preliminary clinical and in vitro evidence shows that indole-3-carbinol has antiestrogenic activity.

Likelihood Possible Evidence D

Flaxseed Oil powder Complex3 drug types · 293 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, using flaxseed oil in combination with anticoagulant or antiplatelet drugs might have additive effects and increase the risk of bleeding.
Small clinical studies show that consuming flaxseed oil might decrease platelet aggregation and increase bleeding time.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, combining flaxseed oil with other antihypertensive drugs might have additive effects and increase the risk of hypotension.
Some clinical evidence suggests that long-term consumption of flaxseed oil can modestly lower systolic and diastolic blood pressure, while other clinical research shows no effect.

Likelihood Possible Evidence D
Ezetimibe (Zetia)

Concomitant use of flaxseed oil and ezetimibe reduces the absorption of alpha-linolenic acid from flaxseed oil.
In one clinical study, concomitant consumption of ezetimibe 10 mg daily with flaxseed oil 2 grams providing 1 gram of alpha-linolenic acid daily blocked the absorption of alpha-linolenic acid, resulting in an overall reduction in alpha-linolenic plasma levels from baseline.

Likelihood Probable Evidence B
Flaxseed Oil powder Complex full monograph & interactions

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.

Estrohalt by Addrena: Common Questions

Does Estrohalt by Addrena interact with any medications?
Yes. Based on its ingredients, Estrohalt has a known interaction with 464 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Estrohalt contains 3 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 Estrohalt if I'm pregnant or breastfeeding?
Diindolylmethane and indole-3-carbinol aren't recommended during breastfeeding—there isn't enough safety data. Diindolylmethane is rated likely safe in pregnancy, but indole-3-carbinol has no safety rating on file for pregnancy. Flaxseed oil has no pregnancy rating, and limited breastfeeding data. Talk with your doctor or pharmacist before taking this product if you're pregnant or nursing.
What are the most common side effects?
Diarrhea, nausea, gas, and headache are the most frequently reported. At higher doses, indole-3-carbinol can cause unsteadiness and tremor. Flaxseed oil at very high doses (30 grams daily or more) may cause loose stools. Most people tolerate it well short-term.
Does this product have any fillers or extra ingredients?
Yes. Beyond the three active ingredients, the tablet contains microcrystalline cellulose, dicalcium phosphate, stearic acid, croscarmellose sodium, magnesium stearate, silicon dioxide, and pharmaceutical glaze. These are standard binders and coatings used in tablets.
Does it work for hormone-related conditions?
The evidence we hold doesn't establish that it works reliably. Diindolylmethane and indole-3-carbinol have insufficient evidence for the conditions they're proposed for, including breast health and cancer prevention. That means research hasn't confirmed benefit yet—not that they don't work.
Is this safe to take long-term?
Short-term safety data is available, but long-term safety for diindolylmethane and indole-3-carbinol isn't well established. Flaxseed oil is generally well tolerated, but the safety notes recommend checking with your doctor before long-term use. Your pharmacist can help you decide based on your individual situation.
