The bottom line No known interaction

We found no known interaction between Ergothioneine and Adalimumab 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.

Ergothioneine and Adalimumab

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 Adalimumab and Ergothioneine 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 Ergothioneine at all — not against Adalimumab, 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.

Ergothioneine safety at a glance

Ergothioneine overall Use caution Appears well tolerated in foods and short-term studies, but long-term supplement safety is not well established.
Pregnancy Avoid There is not enough safety data on supplement doses during pregnancy, so it is best avoided.
Breastfeeding Avoid Safety while breastfeeding has not been studied, so avoid supplemental use.

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

Overlapping uses

What Adalimumab Is Prescribed For, and What Ergothioneine Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Adalimumab is a prescription medicine with approved uses on its FDA label. Ergothioneine is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Adalimumab is prescribed for: Adalimumab injection treats a range of moderate-to-severe inflammatory conditions in adults and some children. These include rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, plaque psoriasis, hidradenitis suppurativa (a chronic skin condition), and non-infectious uveitis (inflammation inside the eye). It is also approved to treat polyarticular juvenile idiopathic arthritis in patients as young as 2 years old, and Crohn's disease in children 6 years and older. Yuflyma is additionally approved for non-infectious uveitis in pediatric patients 2 years and older, and for hidradenitis suppurativa in patients 12 years and older.

Ergothioneine has been studied for:

  • Joint pain studied, not established Ergothioneine has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Ergothioneine for joint pain

    Preliminary clinical research shows that taking two capsules daily for 6 weeks of a specific product (ErgoFlex, Oxis International) containing ergothioneine 500 mcg, along with glucosamine, hyaluronic acid, glycosaminoglycans, collagen, acai, cat's claw, and willow bark has a moderate effect on pain when compared to baseline in patients with mild to moderate chronic joint pain.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Adalimumab on your own; if you are taking Ergothioneine for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Adalimumab

This page covers Ergothioneine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Adalimumab page lists 53 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Active Hexose Correlated Compound (ahcc) (moderate), Alfalfa (moderate), American Ginseng (moderate), Andrographis (moderate) and Ashwagandha (moderate).

By severity: 52 moderate · 1 minor.

From our pharmacist’s overview on the Adalimumab page

“Adalimumab (Humira) works by dialing down an overactive immune system, which is what makes this list so uniform: all 53 supplements on file are flagged for one reason, they may stimulate immunity and could, in theory, blunt the drug's effect. None of the interactions is rated major (52 are moderate, one minor), so for most people this…”

About Ergothioneine

What is Ergothioneine?

  • Antioxidant support
  • Healthy aging and longevity
  • Cellular protection
  • Cognitive and brain health
  • General wellness

Ergothioneine is a naturally occurring amino acid–like compound (an antioxidant) found mostly in mushrooms and made by certain fungi and bacteria. Early laboratory studies suggest it may help protect cells from oxidative stress, but solid human evidence for any specific health benefit is still limited. It appears generally well tolerated, but if you are pregnant, breastfeeding, or taking other medicines, check with your pharmacist or doctor first.

Naturally found in certain mushrooms and other foods; produced by some fungi and bacteria · Capsules, tablets, powders, and as a nutrient in mushroom-based foods

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

Ergothioneine: dosing

There is no officially established dose for ergothioneine supplements. Doses used in research have varied, and a standard recommended amount has not been set.The safest approach is to follow the dosing on the product label and not exceed it. You can also increase your intake naturally by eating more mushrooms.

Taking Ergothioneine and Adalimumab Together: Common Questions

Is it safe to take Ergothioneine with Adalimumab?

Are Ergothioneine and Adalimumab used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Ergothioneine in each. That is a conversation for your prescriber, especially if Adalimumab is being adjusted to a target.
Does Adalimumab interact with any supplements?
Yes. Adalimumab has documented interactions with 53 supplements in our database — Ergothioneine is not one of them. The Adalimumab interaction page linked on this page lists every one, ranked by severity.
