The bottom line No known interaction

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

Lion's Mane Mushroom and Propranolol

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 Propranolol 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.

Lion's Mane Mushroom safety at a glance

Lion's Mane Mushro... overall Use caution Generally well tolerated as a food, but supplement safety has not been well studied long-term.
Pregnancy Avoid Not enough safety data, so it is best to avoid during pregnancy.
Breastfeeding Avoid Not enough safety data, so it is best to avoid while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Propranolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Propranolol is filed under 9 classifications — including beta-blockers, cytochrome p450 2c19 (cyp2c19) substrates, antihypertensive 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 Propranolol’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.

About Lion's Mane Mushroom

What is Lion's Mane Mushroom?

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.

This intravenous (IV) form of propranolol is used in hospital or clinical settings to treat dangerous heart rhythm problems. It is generally reserved for life-threatening arrhythmias (abnormal heart rhythms) or those that occur during anesthesia.

Specific conditions it treats include fast heart rates coming from the upper chambers of the heart (supraventricular tachycardia), certain arrhythmias caused by digitalis toxicity, dangerous ventricular rhythms that haven't responded to other treatments, and fast heart rates caused by excess adrenaline-like substances during surgery.
