HelloPharmacist Scorecard of MenoTrol by Nature's Plus Herbal Actives
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
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
The stated purpose hasn't been mapped to our evidence data yet.
Why this rating?
- We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
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.
At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.
Why this rating?
- 2 of the 2 matched ingredients can interact with medications — Whey Protein, Black Cohosh.
- The most serious interaction on file is rated Major.
- Some involve high-stakes drug classes: Parkinson's medications.
- For scale: 676 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.
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 2 of the 2 matched ingredients.
- Pregnancy & breastfeeding safety ratings cover 2 of 2.
- General safety write-ups exist for 2 of 2.
- Remember: this measures how much safety information exists. Thin data is not the same as being safe.

For each ingredient in MenoTrol with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Black Cohosh
Atorvastatin (Lipitor)
Taking black cohosh with atorvastatin might increase the risk for elevated liver function tests.
In one case report, a patient taking atorvastatin (Lipitor) developed significantly elevated liver function enzymes after starting black cohosh 100 mg four times daily. Liver enzymes returned to normal when black cohosh was discontinued. It is unclear whether the elevated liver enzymes were due to black cohosh itself or an interaction between atorvastatin and black cohosh.
Cisplatin (Platinol-Aq)
Theoretically, black cohosh may reduce the clinical effects of cisplatin.
Animal research suggests that black cohosh might decrease the cytotoxic effect of cisplatin on breast cancer cells.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Some research suggests that black cohosh might inhibit CYP2D6, but there is conflicting evidence.
Some clinical research suggests that black cohosh might modestly inhibit CYP2D6 and increase levels of drugs metabolized by this enzyme. However, contradictory clinical research shows a specific black cohosh product (Remifemin, Enzymatic Therapy) 40 mg twice daily does not significantly inhibit metabolism of a CYP2D6 substrate in healthy study volunteers. Until more is known, use black cohosh cautiously in patients taking drugs metabolized by CYP2D6.
Estrogens
Theoretically, black cohosh may alter the effects of estrogen therapy.
Some research suggests that black cohosh has estrogenic effects. This may enhance or inhibit the effects of estrogen therapy.
Hepatotoxic Drugs
Theoretically, taking black cohosh with hepatotoxic drugs may increase the risk of liver damage.
There is concern that black cohosh might be linked to cases of liver failure and autoimmune hepatitis.
Serotonergic Drugs
Combining serotonergic drugs with black cohosh might cause additive serotonergic effects.
Black cohosh might increase the risk of serotonin syndrome when combined with other serotonergic drugs. Black cohosh acts as an agonist at several serotonin receptor subtypes and might interact with other serotonergic medications. In one case, a 55-year-old female who had been on stable treatment with sertraline 50 mg and duloxetine 60 mg daily developed serotonin syndrome after taking black cohosh extract 40 mg daily for 3 days.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Black cohosh may inhibit one form of OATP, OATP2B1, which could reduce the bioavailability and clinical effects of OATP2B1 substrates.
In vitro research shows that black cohosh modestly inhibits OATP2B1. OATPs are expressed in the small intestine and liver and are responsible for the uptake of drugs and other compounds into the body. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.
Isoplex
Levodopa
Theoretically, whey protein might decrease levodopa absorption.
Small clinical studies show that concomitant ingestion of protein or high doses of leucine or isoleucine (100 mg/kg) and levodopa can exacerbate tremor, rigidity, and the "on-off" syndrome in patients with Parkinson disease.
Bisphosphonates
Theoretically, whey protein might reduce the absorption of bisphosphonates.
Whey protein contains minerals such as calcium that bind bisphosphonates in the gut. Advise patients to take bisphosphonates at least 30 minutes before whey protein, but preferably at a different time of day.
Quinolone Antibiotics
Theoretically, whey protein might decrease quinolone absorption.
Whey protein contains minerals, such as calcium, that can bind to quinolones in the gut. To avoid this interaction, advise patients to take oral quinolones at least 2 hours before or 4-6 hours after whey protein.
Tetracycline Antibiotics
Theoretically, whey protein might decrease tetracycline absorption.
Whey protein contains minerals, such as calcium, that bind to tetracyclines in the gut. To avoid this interaction, advise patients to take oral tetracyclines at least 2 hours before or 4-6 hours after whey protein.
