The bottom line No known interaction

We found no known interaction between Ergogenic Aids and Isocarboxazid 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.

Ergogenic Aids and Isocarboxazid

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 Isocarboxazid and Ergogenic Aids 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Ergogenic Aids at all — not against Isocarboxazid, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Ergogenic Aids safety at a glance

Ergogenic Aids overall Use caution Safety depends entirely on the specific ingredient, dose, and product quality.
Pregnancy Avoid Most ergogenic aids have not been studied in pregnancy, so they are best avoided.
Breastfeeding Avoid Safety while breastfeeding is unknown for most of these products, so caution or avoidance is advised.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Isocarboxazid’s Own FDA Label Lists

This is not an interaction — none of it involves Ergogenic Aids. These are the most notable effects listed in the ADVERSE REACTIONS section of Isocarboxazid’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both.

  • Dry mouth
  • Dizziness
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Isocarboxazid. Read the label on DailyMed › Ergogenic Aids’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Ergogenic Aids side to compare — that is a limit of the record, not a statement that Ergogenic Aids has no side effects.

Everything else you take

See Every Supplement That Interacts With Isocarboxazid

This page covers Ergogenic Aids only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Isocarboxazid page lists 81 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (major), Bitter Orange (major), Brewer's Yeast (major) and Cowhage (major).

By severity: 14 major · 55 moderate · 12 minor.

From our pharmacist’s overview on the Isocarboxazid page

“Isocarboxazid (Marplan) is an MAOI antidepressant, and that drug class carries some of the sharpest supplement and food hazards in the pharmacy, so read this list closely rather than skimming it. Fourteen of the 81 entries rate major, and most of the danger runs through tyramine.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Ergogenic Aids is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Ergogenic Aids reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Ergogenic Aids and Isocarboxazid records this page draws on were last updated July 10, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Ergogenic Aids

What is Ergogenic Aids?

  • Boosting athletic performance
  • Increasing muscle strength and power
  • Improving endurance
  • Supporting muscle growth and recovery
  • Reducing fatigue during exercise

"Ergogenic aids" is a broad term for substances, foods, or techniques used to enhance exercise performance, training, or recovery. A few have solid evidence (such as caffeine, creatine, and beta-alanine), while many others have weak or no proof. Quality and safety vary widely, so talk with a pharmacist or doctor before using any of them.

Not applicable (ergogenic aids are a broad category, not a single plant) · Powders, capsules, tablets, drinks, gels, and bars

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

Ergogenic Aids: dosing

There is no single standard dose for "ergogenic aids" because the term covers many different substances. The right amount depends entirely on the specific ingredient.Follow the directions on the product label, and do not assume that taking more will work better. Higher doses often raise the chance of side effects without adding benefit.Because quality and ingredients vary so much, choose products from reputable companies, ideally ones that have been third-party tested. A pharmacist can help you review the label and decide whether a specific product is appropriate for you.

About Isocarboxazid

What Is Isocarboxazid Used For?

Brand name: Marplan

Marplan (isocarboxazid) is indicated for the treatment of depression — specifically, major depressive disorder. Because it carries serious risks, it is not a first-choice antidepressant. Marplan is generally reserved for patients who have not responded adequately to other antidepressants.

Clinical trials showed Marplan to be effective in adult outpatients with major depressive disorder, including those whose depression was accompanied by anxiety symptoms such as panic or phobias. Marplan is not approved for use in children or adolescents.
