Tranylcypromine and Tyramine / High-Tyramine Foods: what the published research says
PubMed indexes 8 records that name Tranylcypromine and Tyramine / High-Tyramine Foods together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Tranylcypromine and Tyramine / High-Tyramine Foods. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
8 studies naming Tranylcypromine and Tyramine / High-Tyramine Foods.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“MAOIs are known to cause hypertensive crisis when combined with soft cheese due to unopposed release of catecholamines from reduced tyramine metabolisation, leading to injury and possible myonecrosis. Three previous case reports have demonstrated either creatinine kinase or troponin rise with myocardial infarction due to this hypertensive crisis and our case is the fourth with significant hypertension and cardiac biomarker rise related to MAOI, specifically tranylcypromine.”
Names both Tranylcypromine and Tyramine / High-Tyramine Foods in its title.
“The mean tyramine 30 dose with a meal decreased from 1450 mg (range, 800 to 2000 mg) during placebo to 306 mg (range, 150 to 500 mg) during moclobemide (factor, 5.0) and from 1200 mg (range, 1000 to 1600 mg) during placebo to 35 mg (range, 20 to 50 mg) during tranylcypromine (factor, 38.2). The duration of the systolic blood pressure increase was longer with tranylcypromine (126 minutes) than with moclobemide (69 minutes) (p less than 0.01).”
Names both Tranylcypromine and Tyramine / High-Tyramine Foods in its title.

Clinical TrialComparative Study
“A larger increase in the tyramine sensitivity factor was observed following extended selegiline transdermal system treatment at a higher dose (12 mg/24 h), which was significantly decreased following coadministration of tyramine capsules with a meal. These results suggest a wide tyramine safety margin for the selegiline transdermal system and provide evidence that the 6-mg/24-h selegiline transdermal system can be administered safely without dietary tyramine restrictions.”
Names Tranylcypromine and Tyramine / High-Tyramine Foods together in an interaction, co-administration, or pharmacokinetic context.
Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
