Private label mushroom supplements are lion’s mane, reishi, chaga, cordyceps and turkey tail products, sold as capsules, powders or gummies under your own brand. US manufacturers publish minimums from about 500 bottles of extract capsules, with 2,500 units common for capsules and gummies at larger makers. The category is popular, but it’s also one where the FDA has repeatedly issued warning letters over disease claims, such as saying lion’s mane guards against dementia. And it carries a safety lesson: in 2024, Diamond Shruumz chocolates and gummies were linked to 180 illnesses in 34 states. Functional mushrooms can be a good private label product, but only with careful claims and a manufacturer you can verify.
Below I compare manufacturers, explain the claims line, cover the safety and ingredient rules, and show how I’d launch.
Private label mushroom supplement manufacturers
From each company’s own site, checked October 11, 2026:
| Manufacturer | Location | Formats | Published minimum |
|---|---|---|---|
| Aligen | Miramar, Florida | 500 mg extract capsules: chaga, lion’s mane, cordyceps, reishi, turkey tail and blends | 500 bottles |
| NutraSeller | US | Capsules, gummies and stick packs; fruiting body, mycelium or dual extracts | Capsules 2,500 units (60 count); stock gummies 2,500; stick packs 50,000 sticks; $10,000 minimum project |
| TrustWorks | Sun Valley, California | Lion’s mane gummies | Ask; GMP and ISO 9001 |
| DatGummies | Ships from Portugal | Lion’s mane and cordyceps gummies, 60 count | 1,000 units per SKU |
NutraSeller quotes 6 to 8 weeks for a first capsule order, and 12 to 14 weeks for gummies. DatGummies makes its product in the EU, so a US seller would need to check FDA import and labeling requirements before importing.
My take: a 500-bottle capsule run is the lowest-risk way to test this category. Gummies sell well but come with higher minimums and longer lead times.
What the evidence actually says
Mushroom marketing often runs ahead of the science. The official sources are more cautious:
- The National Cancer Institute‘s summary on medicinal mushrooms says the FDA has not approved reishi as a treatment for cancer, and says the same of turkey tail.
- The NIH’s LiverTox database describes reishi as generally well tolerated but implicated in rare single instances of acute liver injury, and describes lion’s mane as generally regarded as safe, with most of its reported effects coming from cell and animal studies.
- A published case report describes a patient who developed kidney damage from oxalates after taking 10 to 15 grams of chaga powder a day for three months.
None of this rules out selling mushroom supplements. It does mean your claims should be modest, and your dosing should be sensible. Honestly, I’d treat any claim that sounds like a medical promise as a red flag in your own copy.
The claims line: where the FDA has acted
Dietary supplements can make structure/function claims with the FDA disclaimer, but the FDA says only a drug can legally make a disease claim. You must notify the FDA no later than 30 days after marketing a supplement with a structure/function claim.
The FDA has warned mushroom sellers who crossed the line. In a November 2023 letter to Lone Star Botanicals, it treated lion’s mane, chaga, reishi and cordyceps powders as unapproved new drugs, citing claims such as “Lion’s Mane mushrooms are thought to guard against dementia” and chaga “lowering cholesterol, blood sugar and blood pressure.”
| Wording | Where it sits |
|---|---|
| “Supports focus as part of a healthy routine” | Structure/function style claim (with disclaimer and evidence) |
| “Guards against dementia” | Disease claim (cited by the FDA) |
| “Lowers cholesterol or blood sugar” | Disease claim (cited by the FDA) |
| “Fights cancer” | Disease claim; the NCI notes the FDA hasn’t approved reishi or turkey tail for cancer |
In practice, the claims on your label, listing, images and ads all count. A customer testimonial you repost can count too.
The Diamond Shruumz lesson
In June 2024, the FDA investigated illnesses linked to Diamond Shruumz chocolate bars, cones and gummies. The products were recalled after the company said they contained muscimol, a compound from Amanita muscaria mushrooms. By the FDA’s final update, there were 180 illnesses in 34 states, 73 hospitalizations and 3 potentially associated deaths.
The FDA has since stated that Amanita muscaria and its constituents, including muscimol, don’t meet the “generally recognized as safe” standard for food. In September 2025, it warned another company over Amanita muscaria microdose capsules and tinctures.
The lesson for a private label brand: functional mushrooms such as lion’s mane and reishi are a different category from psychoactive or “microdosing” products. Stay well away from the latter, and know exactly what’s in your formula.
New dietary ingredients
A dietary ingredient not marketed in the US before October 15, 1994, is a “new dietary ingredient”. Selling it requires a notification to the FDA at least 75 days before the product enters interstate commerce. Common mushroom ingredients from established suppliers are usually covered, but if a manufacturer offers an unusual extract or a novel compound, ask about its regulatory status in writing.
Fruiting body vs mycelium
Manufacturers like NutraSeller offer fruiting body extracts, mycelium extracts or dual extracts. The fruiting body is the mushroom itself; mycelium is the root-like network, often grown on grain. Shoppers in this category increasingly ask which one a product uses.
I’d state it clearly on the label and listing, whatever you choose. Transparency about the source part is one of the easiest ways to stand out from vague competitors.
Selling mushroom supplements on Amazon
Amazon announced that dietary supplements need verification through a third-party Testing, Inspection and Certification organization, effective April 2, 2024, with the requirement expanding across the category. Testing is started through the Manage Your Compliance dashboard, and listings may be removed if they aren’t confirmed compliant by the due date.
Plan the testing time and cost before you order inventory, and keep listing claims identical to your label.
How I’d launch a mushroom supplement brand
- Pick one mushroom and one format. Lion’s mane capsules are a common starting point.
- Choose a manufacturer with a published minimum you can afford, and ask for certifications and batch Certificates of Analysis.
- Decide fruiting body, mycelium or dual extract, and say so on the label.
- Write structure/function claims only, with the FDA disclaimer, and notify the FDA within 30 days of first marketing.
- Plan Amazon testing if you’ll sell there.
- Add blends later, once the first product has reviews.
In my view, the brands that last here sell clarity: which mushroom, which part, how much per serving, and what it’s for in plain, careful language.
Mistakes new mushroom brands make
- Copying competitors’ health claims. Several have drawn FDA warning letters.
- Vague sourcing. “Mushroom blend” tells buyers nothing.
- Chasing trends like microdosing products, which the FDA has acted against.
- Ignoring dosage. More isn’t automatically better, as the chaga case shows.
- No testing budget. Certificates of Analysis and Amazon testing are part of the cost.

FAQ
What is the minimum order for private label mushroom supplements?
Published minimums include 500 bottles of extract capsules at one Florida manufacturer and 2,500 units for capsules or gummies at another.
Can I say lion’s mane helps memory or prevents dementia?
Not as a disease claim. The FDA cited “guard against dementia” in a warning letter. Structure/function claims need the FDA disclaimer and supporting evidence.
Are mushroom supplements safe?
The NIH describes reishi as generally well tolerated with rare liver injury reports, and lion’s mane as generally regarded as safe. A case report linked high-dose chaga powder to kidney damage, so dosing matters.
What happened with Diamond Shruumz?
In 2024, its chocolate bars, cones and gummies were recalled after illnesses linked to muscimol, with 180 illnesses in 34 states reported by the FDA’s final update.
Should I use fruiting body or mycelium?
Either can be sold, but state which one you use. Shoppers increasingly ask, and clear labeling builds trust.
Do mushroom supplements need testing to sell on Amazon?
Amazon requires third-party verification for dietary supplements, announced from April 2, 2024 and expanded across the category.
