Drug & supplement interaction

Mace + Tirzepatide

Tirzepatide brand names: Mounjaro, Zepbound.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Mace and Tirzepatide in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Mace and Tirzepatide

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Tirzepatide and Mace in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Mace safety at a glance

Mace overall Use caution Safe as a culinary spice but large or concentrated doses can be toxic.
Pregnancy Possibly Unsafe When used orally in medicinal amounts. Mace might have abortifacient activity, and its safrole content might be mutagenic. Read the full pregnancy detail
Breastfeeding Use caution Food amounts are probably fine, but avoid concentrated supplements due to lack of safety data.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Tirzepatide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tirzepatide is filed under a single classification — antidiabetes drugs. Mace has documented interactions with 4 drug classes — the most serious being cns depressants (moderate), cytochrome p450 1a2 (cyp1a2) substrates (moderate) and immunosuppressants (moderate) — and none of Tirzepatide’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Mace and Tirzepatide May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Drowsiness Additional detail

    Mace

    “There are no reports of adverse neurologic or central nervous system (CNS)-related events due to ingestion of mace. However, mace contains myristicin, which is structurally similar to certain hallucinogenic chemicals. High intake of nutmeg, a similar herb, has been reported to cause headache, dizziness, drowsiness, hot and cold sensations, sensations of limb loss, convulsions, and coma.”

    Mace

    “There are no reports of adverse gastrointestinal events due to ingestion of mace. However, mace contains myristicin, which is structurally similar to certain hallucinogenic chemicals. High intake of nutmeg, a similar spice, has been reported to cause nausea and vomiting, epigastric pain, and gastroenteritis. Theoretically, high intake of mace may have similar effects.”

    Tirzepatide

    Listed in the ADVERSE REACTIONS section of the FDA label for Tirzepatide, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Mace but not commonly for Tirzepatide: hallucinations, confusion, anxiety or restlessness and a fast or pounding heartbeat.

Effects for Tirzepatide come from the ADVERSE REACTIONS section of its FDA label; effects for Mace come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 140,435 voluntary FDA FAERS reports for Tirzepatide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

About Mace

What is Mace?

  • Digestive upset and gas
  • Flavoring and culinary spice
  • Nausea
  • Appetite stimulation
  • Traditional pain or muscle relief

Mace is the lacy red covering of the nutmeg seed and comes from the same tree as nutmeg. It is mostly used as a cooking spice and in traditional medicine for digestion, but there is little solid human research to support its health uses. In normal food amounts it is generally safe, but large doses can be toxic, so use it as a spice and check with your pharmacist before taking concentrated supplements.

Myristica fragrans · Myristicaceae · The dried red, lacy covering (aril) of the nutmeg seed · Whole dried blades, ground powder, essential oil, capsules

An interaction check asks whether these two react with each other — it does not ask whether Mace is a good idea for someone in your situation. Here is what our Mace record says about it on its own.

Mace: dosing

There is no established standardized medicinal dose for mace. As a spice, the amount used in cooking is small and considered safe.If you choose to use a mace supplement, follow the directions on the product label and do not exceed them. Because high amounts can be toxic, more is not better.

Taking Mace and Tirzepatide Together: Common Questions

Is it safe to take Mace with Tirzepatide?
We do not list a known interaction between Mace and Tirzepatide. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Mace and Tirzepatide have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Mace and Tirzepatide combination checked?
Interactions in our licensed database are recorded against drug classes. Tirzepatide is filed under 1 classification, and Mace has documented interactions with 4 drug classes — none of Tirzepatide's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Mace interact with any other medications?
Yes. Mace has 500 documented drug interactions in our database — Tirzepatide is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Tirzepatide interact with any supplements?
Yes. Tirzepatide has documented interactions with 239 supplements in our database — Mace is not one of them. The Tirzepatide interaction page linked on this page lists every one, ranked by severity.
