Safety first. Supplements can cause side effects and interact with medicines. Read mushroom safety and interactions before you use any mushroom product.

What a mushroom gummy is

A gummy is a dosage form. The FDA lists gummies among the forms dietary supplements can take, alongside pills, capsules, liquids and powders. [3] A gummy can therefore contain a medicinal mushroom such as lion's mane (Hericium erinaceus [4]) or reishi (Ganoderma lucidum [5]), but the form tells you nothing about which species, which part or how much. Those facts are on the label, if at all; see mushroom supplement forms and how to read a mushroom supplement label.

Reading the label

What to find	Why it matters	Where it comes from
Serving size and servings per container	The panel amounts are for one serving, which may be more than one gummy.	The FDA says a Supplement Facts panel must list the serving size and servings per container. [3]
Added sugars	Gummies are sweetened; the Daily Value for added sugars is 50 g on a 2,000-calorie diet.	[6]
Species and part	Fruiting body, mycelium and extracts are different products.	See fruiting body vs mycelium.
Other ingredients	Ingredients not declared in the Supplement Facts panel are listed separately as "other ingredients".	[3]
Psychoactive wording	The reports above involved gummies marketed as "nootropic" or for "legal highs", or with Amanita on the label.	[2] [1]

Added sugars include sugars added during processing, such as sucrose or dextrose. [6] The Dietary Guidelines for Americans recommend keeping added sugars under 10 percent of daily calories. [6] Proper evidence not found: we read no source reporting typical sugar or mushroom amounts in mushroom gummies, so we make no statement on them; compare the pack in your hand.

What research shows

Question	What the source found	Strength of evidence
Do mushroom gummies improve memory, mood, focus or immunity?	Proper evidence not found. We searched PubMed for "mushroom gummies" (7 records) and none was a human trial of a medicinal mushroom gummy; the relevant records were about psychoactive products.	Marketing claim
Do fungal beta-glucans, a fiber in mushroom cell walls, affect health?	A review of 34 trials found inconsistent immune findings at the cellular and molecular level, using amounts from 2.5 to 1000 mg a day in various forms. [7]	Mixed; not gummy trials

A trial of a capsule or extract cannot be carried over to a gummy, because the amount, extract and binder differ. For lion's mane trials by outcome see lion's mane for memory and cognition.

Frequently asked questions

Do mushroom gummies work?

Proper evidence not found. We found no human trial of a medicinal mushroom gummy. A trial of another form does not transfer.

How much sugar is in mushroom gummies?

It varies by product and we found no source with typical values. Look for the added sugars line; the FDA's Daily Value is 50 grams a day. [6]

Are mushroom gummies safe?

It depends on the product. Some gummies sold as mushroom products have contained psychoactive substances. [2] [1] Ask a clinician before use.

Do lion's mane gummies have side effects?

We found no gummy-specific studies. See lion's mane side effects and allergy.

Are mushroom gummies regulated?

The FDA says it does not approve dietary supplements before they are marketed. [8] See are mushroom supplements regulated.

Safety first: not every "mushroom gummy" is a medicinal mushroom product

Some gummies sold as "mushroom" products contain psychoactive compounds. A US CDC report describes Schedule I substances found in nootropic gummies marketed as containing Amanita muscaria or other mushrooms. [1] A laboratory study of eight psychoactive mushroom gummies bought in Portland, Oregon, concluded that their labeling was overall inaccurate: seven of the eight contained psilocin, and one labeled psilocybin-free contained psilocybin. [2] Those are a different subject from lion's mane or reishi products; see medicinal vs psychedelic mushrooms. This library gives no use or preparation information for psychoactive fungi.

If a child or adult has an unexpected reaction after eating a gummy, call Poison Help at 1-800-222-1222 (US), or 911 for collapse, seizure or confusion. For other countries see poison help by country.

Quality and who should ask first

The FDA says it is not authorized to approve dietary supplements for safety and effectiveness before they are marketed. [8] Independent testing and certificates are discussed in mushroom testing and certificates of analysis. People who are pregnant or breastfeeding, have allergies to mushrooms, diabetes, kidney or liver disease, take medicines or face surgery should ask a clinician or pharmacist; see children and teens and how interactions work.
