HelloPharmacist Scorecard of Genius Estrogen Balance by The Genius Brand

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.

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.

Genius Estrogen Balance contains 3 active ingredients: diindolylmethane (a compound from cruciferous vegetables), grape extract (from the seed and fruit), and BioPerine black pepper extract (piperine). These are combined in a vegetable capsule alongside inactive ingredients — rice and ascorbyl palmitate (a form of vitamin C used as a preservative).

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 balance and hormone modulation.
  • We looked for evidence on: Menopausal symptoms, Premenstrual syndrome (PMS), Dysmenorrhea, Benign prostatic hyperplasia (BPH), Prostate cancer, Hormonal acne — and 2 related terms.
  • The closest evidence on file: Grape is rated "Insufficient Reliable Evidence To Rate" for Menopausal symptoms (Natural Medicines).
  • Also on file: Grape is rated "Insufficient Reliable Evidence To Rate" for Premenstrual syndrome (PMS).
  • Also on file: Black Pepper is rated "Insufficient Reliable Evidence To Rate" for Dysmenorrhea.

The evidence for what this product actually works for is very limited. For diindolylmethane, there isn't enough reliable data to say whether it helps benign prostatic hyperplasia, breast cancer, uterine cancer, cervical dysplasia, colorectal cancer, or breast pain.

Grape extract shows possibly effective evidence for chronic venous insufficiency (a circulation issue in the legs), but possibly ineffective evidence for chemotherapy-related nausea, allergies, and weight. Black pepper has insufficient evidence for all the conditions listed — allergies, asthma, athletic performance, headache, depression, and diarrhea.

If you're considering this for a specific concern, talk it over with your doctor to see if there's stronger evidence for something else.

The evidence, ingredient by ingredient Diindolylmethane Grape Black Pepper

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 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 is DRESS (drug rash with eosinophilia and systemic symptoms). One stroke case has been reported in a patient taking 200 mg daily alongside other supplements, though that person had multiple stroke risk factors and it's unclear if diindolylmethane played a role.

Grape extract is generally well tolerated; common side effects include abdominal pain, diarrhea, dry mouth, indigestion, headache, joint pain, and nausea, with rare anaphylaxis to grape skin reported. Black pepper is well tolerated in food amounts and single doses; common effects are burning aftertaste, indigestion, and reduced taste.

For long-term or supplement-strength use, safety data are limited. Pregnancy safety for diindolylmethane is rated likely safe, but the safety data advise against use due to possible hormone effects — talk with your doctor if you're pregnant or planning to become pregnant.

For lactation, there isn't enough data on diindolylmethane, and it's best avoided while breastfeeding. Grape is rated likely safe in pregnancy and during breastfeeding as whole fruit, but concentrated supplements in pregnancy aren't well studied and should be avoided.

Black pepper is likely safe in pregnancy as a food spice, but supplement-strength piperine safety is not well studied, so avoid concentrated supplements during pregnancy without medical advice. Black pepper is likely safe while breastfeeding.

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 — Grape, Black Pepper, Diindolylmethane.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,111 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 taking this product, double-check with your doctor or pharmacist if you take any estrogens (including birth control or hormone therapy), water pills that lower sodium, heart or blood pressure drugs like propranolol, blood thinners or antiplatelet drugs, anti-seizure medications like phenytoin, theophylline, HIV drugs like nevirapine, antibiotics like rifampin, cyclosporine, or medications broken down by your liver through the CYP1A2, CYP2D6, CYP3A4, or CYP2E1 pathways. These pathways include many common drugs — use the medication checker below to see if yours is one of them.

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 may appeal to someone looking for support around estrogen balance, but the evidence for its effectiveness is not established in our data. The bigger concern is the number of medications it can interact with — especially if you take an estrogen, blood thinner, anti-seizure drug, heart medication, or HIV or antibiotic therapy.

Before you start it, check your exact medications using the tool on this page, and confirm the results with your own doctor or pharmacist — don't make any changes without their input.

Likelihood Possible Evidence D
Atorvastatin (Lipitor)

Theoretically, black pepper might increase blood levels of atorvastatin.
Animal research shows that taking piperine, a constituent of black pepper, 35 mg/kg can increase the maximum serum concentration of atorvastatin three-fold. This has not been reported in humans.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, black pepper might increase the effects and side effects of cyclosporine.
In vitro research shows that piperine, a constituent of black pepper, increases the bioavailability of cyclosporine. This has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, black pepper might increase levels of drugs metabolized by CYP2D6.
In vitro research suggests that some constituents of black pepper inhibit CYP2D6. This has not been reported in humans.

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

Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, black pepper might increase blood levels of lithium due to its diuretic effects. The dose of lithium might need to be reduced.
Black pepper is thought to have diuretic properties.

Likelihood Probable Evidence D
Nevirapine (Viramune)

Black pepper might increase blood levels of nevirapine.
Clinical research shows that piperine, a constituent of black pepper, increases the plasma concentration of nevirapine. However, no adverse effects were observed in this study.

Likelihood Probable Evidence D
P-Glycoprotein Substrates

Theoretically, black pepper might increase levels of P-glycoprotein substrates.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit P-glycoprotein.

Likelihood Possible Evidence D

Theoretically, black pepper might increase the sedative effects of pentobarbital.
Animal research shows that piperine, a constituent of black pepper, increases pentobarbital-induced sleeping time.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Black pepper might increase blood levels of phenytoin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin. Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin. Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper.

Likelihood Possible Evidence B
Propranolol (Inderal)

Black pepper might increase blood levels of propranolol.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol.

Likelihood Possible Evidence D
Amoxicillin (Amoxil, Trimox)

Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin. This has not been reported in humans.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects. In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner.

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

Theoretically, black pepper might decrease levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that black pepper induces CYP1A2. This has not been reported in humans.

Likelihood Possible Evidence D
BioPerine Black Pepper full monograph & interactions

Grape9 drug types · 910 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, grape extracts may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that grape extracts might decrease platelet aggregation.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Ingesting grape juice with cyclosporine can reduce cyclosporine absorption.
A small pharmacokinetic study in healthy young adults shows that intake of purple grape juice 200 mL along with cyclosporine can decrease the absorption of cyclosporine by up to 30% when compared with water. Separate doses of grape juice and cyclosporine by at least 2 hours to avoid this interaction.

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

Theoretically, grape juice might reduce the levels of CYP1A2 substrates.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of CYP1A2.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, grape seed extract may increase the levels of CYP2D6 substrates.
In vitro evidence suggests that grape seed extract might inhibit CYP2D6 enzymes. However, this interaction has not been reported in humans.

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

Theoretically, grape seed extract might increase the levels of CYP2E1 substrates.
In vitro and animal research suggests that grape seed proanthocyanidin extract inhibits CYP2E1 enzymes. However, this interaction has not been reported in humans.

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

It is unclear if grape seed extract inhibits or induces CYP3A4; research is conflicting.
In vitro evidence suggests that grape seed extract might inhibit CYP3A4 enzymes. However, evidence from animal research shows that grape seed extract may induce CYP3A4 in the liver. So far, these interactions have not been reported in humans.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, long-term intake of grape seed extract might decrease the effects of midazolam.
Animal research shows that subchronic ingestions of grape seed extract can increase the elimination of intravenous midazolam by increasing hepatic CYP3A4 activity. Single doses of grape seed extract do not appear to affect midazolam elimination.

Likelihood Possible Evidence D
Phenacetin

Grape juice might decrease phenacetin absorption.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of cytochrome P450 1A2 (CYP1A2).

Likelihood Possible Evidence B
Cytochrome P450 2C9 (Cyp2C9) Substrates

It is unclear if grape juice or grape seed extract inhibits CYP2C9; research is conflicting.
In vitro evidence shows that grape seed extract or grape juice might inhibit CYP2C9 enzymes. However, a small pharmacokinetic study in healthy adults shows that drinking 8 ounces of grape juice once does not affect the clearance of flurbiprofen, a probe-drug for CYP2C9 metabolism. The effects of continued grape juice consumption are unclear.

Likelihood Unlikely Evidence D

3,3'-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.

Genius Estrogen Balance by The Genius Brand: Common Questions

Does Genius Estrogen Balance by The Genius Brand interact with any medications?
Yes. Based on its ingredients, Genius Estrogen Balance has a known interaction with 1,110 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Genius Estrogen Balance 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.
Is it safe to take this if I'm pregnant?
The safety data for diindolylmethane, the main ingredient, advise against use during pregnancy due to possible effects on hormones — there isn't enough information to know either way. Grape extract is likely safe when eaten as whole fruit, but concentrated grape supplements in pregnancy aren't well studied. Black pepper as a food spice is likely safe, but supplement-strength piperine should be avoided in pregnancy without medical advice. Talk with your doctor about whether this product is right for you during pregnancy.
Is it safe while breastfeeding?
There isn't enough safety data for diindolylmethane while breastfeeding, so it's best to avoid it. Grape extract is rated likely safe when eaten as whole fruit, but there isn't enough information on concentrated grape supplements. Black pepper appears fine during breastfeeding based on food use. Check with your doctor or pharmacist before starting any supplement while nursing.
What are the most common side effects?
The most common side effects from diindolylmethane are diarrhea, gas, headache, nausea, rash, and vomiting. Grape extract can cause abdominal pain, diarrhea, dry mouth, indigestion, headache, joint pain, and nausea. Black pepper may cause a burning aftertaste, indigestion, and reduced taste perception. Most people tolerate these ingredients without problems, but if you're sensitive to digestive upset, start cautiously.
Does this product actually work for hormone balance?
There isn't enough reliable evidence in our data to say whether diindolylmethane helps with hormone balance or the conditions listed on the label — like breast cancer or benign prostatic hyperplasia. If you're looking for support for a specific condition, ask your doctor what the research actually shows.
What is BioPerine black pepper doing in this formula?
BioPerine is piperine, a compound from black pepper. It's often added to supplements to increase how well other ingredients are absorbed by your body. However, piperine also raises the blood levels of many medications — which is why it's important to check this product against your prescriptions before starting.
