HelloPharmacist Bottom Line
Our Pharmacist Explains
What is this? The interaction data in the HelloPharmacist supplement database is licensed from Natural Medicines Pro by TRC Healthcare (Therapeutic Research). HelloPharmacist pharmacists often add our own analysis and context on top of that licensed data — such as this Bottom Line summary and the notes on individual interaction pages — and any such commentary is noted as ours.

If you are using menotropins (Menopur, Repronex) for fertility treatment, I would hold off on every one of the 21 supplements on this page until your prescriber weighs in. All of them touch thyroid hormone activity in one direction or the other, and steady thyroid function matters when you are trying to get a cycle to succeed. Tiratricol carries the single major rating; it is essentially a thyroid hormone itself and has no place in self-treatment.

The rest, 19 rated moderate and one minor, split into two camps. Some can amplify thyroid effects, like ashwagandha and the iodine-rich seaweed products. Others can blunt them, including L-carnitine and niacin. Either direction can throw off the balance you and your fertility team are working toward, so bring your full supplement list to them, and treat tiratricol as off limits unless it is prescribed.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
  • Each entry links to a full report with the clinical detail, likelihood, evidence level, and citations for that exact combination.
  • Content is reviewed by licensed HelloPharmacist pharmacists — see our data sources and editorial standards.

How Does Our Interaction Checker Work?

Behind every verdict on this page is a category system. Our source database doesn’t document supplement interactions drug-by-drug — it documents them against groups of medications that behave the same way (for example, “drugs processed by the CYP3A4 liver enzyme” or “blood-thinning medications”).

So the check works in three steps: (1) Menotropins is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Menotropins, and (3) each ingredient keeps its own severity, likelihood, and evidence grades from the underlying record. That’s why one supplement can carry several records for one drug — it may interact through more than one category.

Menotropins sits in 1 interaction category. Open any one to see what the group means:

Thyroid Hormone 21 ingredients

A pharmacology grouping from our source database: medications in this group share a property that certain supplements are known to interact with, so an interaction documented for the group applies to every drug in it.

21 of the supplement ingredients on this page reach Menotropins through this category.

Menotropins & Supplements: Common Questions

What supplements interact with Menotropins?
In our interaction database, 21 supplement and herbal ingredients have an interaction with Menotropins on file — 1 rated major, 19 moderate, and 1 minor. That number sounds scarier than it is: severity matters far more than the count, which is why the list on this page is ranked instead of alphabetical. Start at the top. The highest-ranked right now: Tiratricol, Acetyl-l-carnitine, Ashwagandha.
Which Menotropins supplement interactions are the most serious?
The 1 major-rated combination — led by Tiratricol — deserve real caution: these are the ones generally best avoided, or used only with your prescriber watching. If you take any of them today, don't panic and don't stop anything abruptly — call your pharmacist first. Jump to the ranked list.
Can I take vitamins or supplements while on Menotropins?
That depends entirely on which supplement. The honest answer for Menotropins is in the ranked list above — and if what you take is a combination product with a dozen ingredients, don't check them one by one: photograph the label with our scanner and we'll check the whole thing at once. Try the label scanner or the interaction checker.
Do brands like Repronex have the same supplement interactions as Menotropins?
Yes — Repronex, Menopur all contain Menotropins, so everything on this page applies to them equally. Interactions belong to the active drug, never to the brand on the box; the same is true of generics.
Where do these interaction ratings come from?
Every rating comes from the Natural Medicines database — the same evidence-graded reference pharmacists and hospitals use — and each interaction carries three separate grades: severity (how bad it can be), likelihood (how well it's documented in studies and case reports), and an evidence level. Our pharmacists review the content; we never let an AI decide an interaction. See how to read the ratings and our editorial policy.
What about Menotropins and my other medications?
This page covers Menotropins against supplements and herbal ingredients. Checking Menotropins against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side. Head to the drug–drug interaction checker.
