Drug & supplement interaction

Lion's Mane Mushroom + Raloxifene

Raloxifene brand name: Evista.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 20, 2026

The bottom line No known interaction

We found no known interaction between Lion's Mane Mushroom and Raloxifene 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

Lion's Mane Mushroom and Raloxifene

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 Raloxifene and Lion's Mane Mushroom 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.

How we checked

Why No Interaction Is Listed for Raloxifene

Interactions in our licensed database are recorded against drug classes, not just single drug names. Raloxifene is filed under 2 classifications — including oral drugs. Lion's Mane Mushroom has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and immunosuppressants (moderate) — and none of Raloxifene’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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Lion's Mane Mushroom and Raloxifene 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.

Overlapping uses

What Raloxifene Is Prescribed For, and What Lion's Mane Mushroom Has Been Studied For

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

Raloxifene is prescribed for: Raloxifene tablets are approved for postmenopausal women for two main purposes: treating and preventing osteoporosis (thinning of the bones), and reducing the risk of invasive breast cancer. The breast cancer risk-reduction use applies to postmenopausal women who already have osteoporosis or who are otherwise considered at high risk for invasive breast cancer. Important limits apply: raloxifene is not used to treat existing breast cancer, prevent breast cancer from coming back, or prevent noninvasive breast cancer. It does not eliminate breast cancer risk entirely.

Women taking it for breast cancer risk reduction should continue regular breast exams and mammograms.

Lion's Mane Mushroom has been studied for:

Cancer studied, not established Lion's Mane Mushroom has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Lion's Mane Mushroom for cancer

Although there is interest in using oral lion's mane mushroom for cancer, there is insufficient reliable information about the clinical effects of lions mane mushroom for this purpose.

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 Raloxifene on your own; if you are taking Lion's Mane Mushroom for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Raloxifene

This page covers Lion's Mane Mushroom only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Raloxifene page lists 18 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 8 moderate · 9 minor.

From our pharmacist’s overview on the Raloxifene page

“Raloxifene (Evista) works quietly, protecting bone and lowering breast cancer risk over years, so anything that weakens the dose causes damage you may not feel until much later, and I read this list with real wariness. Nearly every entry is a fiber, gum, or mucilage that can blunt how much raloxifene your body absorbs.”

About Lion's Mane Mushroom

What is Lion's Mane Mushroom?

Memory and cognitive support
Nerve health
Mood and anxiety
Immune support
General wellness/antioxidant

Lion's mane is an edible mushroom that is popular as a 'nootropic' for memory, focus, and nerve health, but solid human evidence is still limited and early. It is generally well tolerated as a food and supplement, but talk with your pharmacist or doctor before starting it, especially if you are pregnant, breastfeeding, or have allergies.

Hericium erinaceus · Hericiaceae · Fruiting body and mycelium · Capsules, powders, tablets, tinctures, teas, and as a culinary mushroom

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

Lion's Mane Mushroom: dosing

There is no official or standardized dose for lion's mane. The amounts used in studies have varied widely depending on the form (whole mushroom, fruiting body extract, or mycelium).The best advice is to follow the directions on the product label and not to exceed them. Because products differ a lot in strength and quality, look for brands that use third-party testing.

Taking Lion's Mane Mushroom and Raloxifene Together: Common Questions

Is it safe to take Lion's Mane Mushroom with Raloxifene?

We do not list a known interaction between Lion's Mane Mushroom and Raloxifene. 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 Lion's Mane Mushroom and Raloxifene 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.

Are Lion's Mane Mushroom and Raloxifene 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 Lion's Mane Mushroom in each. That is a conversation for your prescriber, especially if Raloxifene is being adjusted to a target.

How was the Lion's Mane Mushroom and Raloxifene combination checked?

Interactions in our licensed database are recorded against drug classes. Raloxifene is filed under 2 classifications, and Lion's Mane Mushroom has documented interactions with 3 drug classes — none of Raloxifene'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 Lion's Mane Mushroom interact with any other medications?

Yes. Lion's Mane Mushroom has 327 documented drug interactions in our database — Raloxifene 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 Raloxifene interact with any supplements?

Yes. Raloxifene has documented interactions with 18 supplements in our database — Lion's Mane Mushroom is not one of them. The Raloxifene interaction page linked on this page lists every one, ranked by severity.
