Bulk Reishi Mushroom Powder and Extract for Supplement Manufacturing
Reishi powder is a dried, milled ingredient made from the fruiting body of red reishi, a woody Ganoderma mushroom that grows on hardwood. It comes as whole mushroom powder, as a hot water extract, or as a dual extract made with water and ethanol. Buyers specify it by species, mushroom part, beta-glucan content, and triterpene content. We supply it in bulk to supplement brands, contract manufacturers, and formulators. You can request testing documents and samples on the quote form.
A cultivated mushroom ingredient with two measurable marker groups
Reishi is easy to compare across suppliers once you pin down the species name, the mushroom part, and the extraction. Each of those choices shows up in the beta-glucan and triterpene results on the COA.
A species name worth checking
Red reishi is still sold as Ganoderma lucidum. Mycologists now place the cultivated Asian mushroom under G. lingzhi or G. sichuanense. Ask which name the COA uses and how identity was confirmed.
Three distinct materials
Fruiting body is the woody cap and stem. Mycelium is the rootlike network, often grown on grain. Spore powder is a separate product. Each has its own composition and spec.
Beta-glucans and triterpenes
Beta-glucans are cell wall polysaccharides that carry into hot water extracts. Triterpenes such as ganoderic acids carry into ethanol. A dual extract combines both steps in one powder.
A naturally bitter taste
The bitter taste comes mostly from triterpenes. Whole fruiting body powder and dual extracts taste more bitter than plain water extracts, which affects drink mixes.
Fine powder for dry formats
Fruiting body powder is tan to reddish brown and fibrous, so it does not fully dissolve. Extracts are brown, finer, and disperse more evenly in liquids.
A fingerprint you can match
An HPTLC fingerprint of triterpenes compared with an authenticated fruiting body reference gives your quality team a clear identity check for each lot.
Where formulators use reishi powder and extract
Both forms fit measured formats where fill weight and serving size are controlled, including:
- Capsules
- Compressed tablets
- Single ingredient powders
- Mixed mushroom blends
- Tea blends
- Mushroom coffee and cacao mixes
- Powdered drink mixes
- Stick packs and sachets
- Private label programs
Plan fill weights from the confirmed beta-glucan figure on each COA. In drink mixes, cacao, cinnamon, and vanilla sit well against reishi's bitterness, so run taste trials at your target serving before you lock the formula.
What to check before you buy reishi powder
Two reishi ingredients with the same name can differ in species, mushroom part, extraction, and assay method. Review these points together, and ask for lot documents before you approve a supplier.
Species and identity method
Ask which Ganoderma name appears on the COA and how identity was confirmed. DNA testing or an HPTLC triterpene fingerprint against a fruiting body reference are the usual checks.
Fruiting body, mycelium, or spores
Confirm the material and its share in any blend. Mycelium grown on grain can carry some grain into the powder, so ask about the substrate.
Beta-glucan by a named method
Ask for beta-glucan by the Megazyme enzymatic method. Reishi results shift with the acid used in the test, so compare lots only when the method matches.
Alpha-glucan and carrier
Ask for alpha-glucan (starch) on the same report, and whether maltodextrin or another carrier is added. Some bulk reishi extracts on the market list maltodextrin.
Triterpene result and method
If your grade states triterpenes, ask whether they were measured as total triterpenes by UV or as ganoderic acids by HPLC. The two methods give different numbers.
Contaminant limits and origin
Check heavy metals by ICP-MS, microbial limits, pesticide residues, and the country of cultivation. Brands selling into California compare lead per daily serving with Proposition 65 levels.
Label wording: Decide on one botanical name with your regulatory team, then make the label, spec sheet, and COA match it. State the mushroom part on the label as your advisor recommends.
Typical specification for reishi extract
These values reflect a common hot water fruiting body extract. Whole mushroom powder and dual extracts have their own specs. Final figures come from the specification sheet and COA for your lot. NLT means not less than, and NMT means not more than.

Quality standards for reishi mushroom powder and extract
Reishi fruiting body has two USP-NF monographs, one for the whole dried mushroom and one for its powder. Both set minimum triterpenoic acids and water soluble polysaccharides by HPLC on the dried basis.
USP Ganoderma Lucidum Fruiting Body Powder
The monograph requires NLT 0.3% triterpenoic acids, the sum of ten named ganoderic and ganoderenic acids by HPLC at 257 nm. It also requires NLT 0.7% water soluble polysaccharides, read as five sugars by HPLC. Both figures are on the dried basis. Loss on drying is NMT 17.0% and total ash NMT 4.0%.
Three identity tests
Test A is HPTLC with toluene, ethyl formate, and formic acid (5:5:0.2), sprayed with sulfuric acid in alcohol. The sample must match the USP reference extract and show a violet band above ergosterol. Tests B and C match HPLC retention times for ten triterpenoic acids and five sugars.
Chinese Pharmacopoeia lingzhi
The Chinese Pharmacopoeia lists G. lucidum and G. sinense as lingzhi. Its 2020 edition sets polysaccharides at NLT 0.90% and triterpenes at NLT 0.50%, expressed as oleanolic acid. Those totals are read against single reference compounds, so they do not match the USP sum of ten named acids.
Beta-glucan and alpha-glucan
The USP monographs have no beta-glucan test, so buyers add the Megazyme method. In one supplier's published screening, reishi extracts read 26.8 to 31.9% beta-glucan with 0.1 to 0.6% starch. Ask which acid the lab used, since sulfuric acid reads higher than hydrochloric acid on Ganoderma.
Species names and DNA tests
DNA sequencing of commercial reishi usually identifies G. lingzhi, the cultivated Asian species, even when the label reads G. lucidum. The USP monograph uses the name G. lucidum. Agree on the species reference before you set a DNA identity test, or a correct lot can fail it.
Contaminant limits to build on
The USP monographs set arsenic NMT 2.0 µg/g, cadmium NMT 1.0 µg/g, lead NMT 5.0 µg/g, and mercury NMT 1.0 µg/g. They allow total aerobic counts up to 100,000 cfu/g and require absence of Salmonella and E. coli. Some lot specs for reishi extracts set 0.5 ppm for lead and cadmium.
Sourcing and processing practices for reishi
Reishi lots differ most in species, material, and extraction steps. These practices give QA teams specific points to check and record.
Keep spores and fruiting body apart
Spore powder is a separate article with its own standards, ISO/TS 25006:2025 and GB/T 29344-2023. A 12 batch comparison found spore powder triterpenoid levels below half those of the fruiting body. If spores go into a fruiting body product, declare them and specify them on their own.
Write the triterpene method into the contract
Name the method for any triterpene figure: the USP sum of ten acids by HPLC, or a total by UV. Generic UV totals also count terpenes beyond the ganoderic acids. In spore products, vanillin and perchloric acid tests can read high because spore fatty acids react too.
Declare each extraction step
Hot water carries the polysaccharides, and an ethanol step carries the triterpenes. For a dual extract, ask for the solvent, temperature, and ratio of each step, and the share of each fraction. Keep these in the lot file, since they explain shifts in the COA.
Dry and store the raw mushroom well
USP allows dried whole fruiting body up to 17.0% loss on drying, far wetter than a finished extract. One brand's extract capsules are specified at NMT 7.0%, with water activity below 0.73. Keep dried mushroom in well closed containers, away from light and moisture, until it is milled or extracted.
Test microbes the USP way
The USP monographs add a limit of NMT 1,000 cfu/g for bile tolerant gram-negative bacteria. Supplier sheets often leave this test out. Ask for it beside total aerobic count, yeast and mold, Salmonella, and E. coli.
Formulator tips for reishi
Use these points when you set label figures, fill weights, and incoming tests. Figures come from USP monographs, lot COAs, and supplier sheets.
- Do the triterpene math on the COA method. 150 mg of an extract at 9% ganoderic acids gives 13.5 mg per capsule.
- Compare triterpene figures only on the same method and basis. The USP figure is a sum of ten named acids on the dried basis, while UV totals count a wider group.
- Convert per serving specs before you compare. NLT 175 mg beta-glucan and NMT 25 mg alpha-glucan per 1 g serving equal NLT 17.5% and NMT 2.5%.
- Plan fill from bulk density. At 0.30 to 0.70 g/mL, 500 mg of extract needs about 0.7 to 1.7 mL. Small extract amounts, such as 150 mg per capsule, need a filler to fill the shell, and the filler goes on the label.
- If your label states USP compliance, test to the monograph text. It covers whole and powdered fruiting body on the dried basis, with ten named acids and five sugars.
- Set an incoming test plan. Run HPTLC identity, Megazyme beta-glucan and alpha-glucan, and ICP-MS metals on every lot. Run triterpenoic acids by HPLC for each new supplier and at set intervals.
- Do not compare spore powders on triterpenes. Spore products hold little triterpenoid material, so use the sporoderm broken rate and their own markers.
- Recheck beta-glucan, triterpenes, and loss on drying before you use stock past its retest date. Published brand COAs date reishi lots for use within two to three years of production.
Helping shoppers read a reishi label
Brands and their customer service teams field the same label questions again and again. These answers stick to what the ingredient is and how it is labeled.
What the label line means
A typical line reads reishi (Ganoderma lucidum) fruiting body extract. USP labeling asks for the Latin binomial and the part of the fungus used. Some brands print G. lingzhi, the name mycologists now use for cultivated red reishi.
How to read a triterpene or beta-glucan figure
A percentage tells you how much of the extract is that compound group by the stated test. A note such as by HPLC or by UV names the method, and the two give different numbers for the same powder.
Independent quality programs
Programs such as the USP Dietary Supplement Verification Program and NSF/ANSI 173 certification check finished products against their labels and contaminant limits. USP also publishes monographs for reishi fruiting body and its powder.
Normal look, taste, and home storage
Reishi extract is brown to reddish brown and tastes bitter, which is normal. Color can vary a little from lot to lot. Keep the container closed at room temperature, away from light and moisture, which matches the USP storage wording.
Storage and handling for bulk reishi powder
Mushroom powders and extracts hold their spec longest when they stay sealed, dry, and out of light. These steps keep the powder in good condition between production runs.
Keep it sealed
Close the inner liner after each use and press out the air. Hot water extracts pick up moisture from the air and can cake when left open.
Store cool and dry
Keep bags off the floor in a dry room, away from heat sources. Follow the temperature range on the spec sheet.
Keep away from light
Leave the powder in its original opaque packaging. Light and heat can shift color over time.
Rotate stock
Record the lot number and retest date for each bag. Send older lots to production first.
Reishi buyer FAQ
Quick answers to the questions procurement and quality teams ask most.
Is reishi Ganoderma lucidum or Ganoderma lingzhi?
Most red reishi in trade is the cultivated Asian species that mycologists call Ganoderma lingzhi or G. sichuanense, even though it is often sold as G. lucidum. Pick one name with your regulatory team and make the label, spec, and COA agree.
Is reishi powder made from the fruiting body, mycelium, or spores?
It can be made from any of the three, so the spec sheet should name the material. Fruiting body is the woody mushroom itself, mycelium is often grown on grain, and spore powder is a separate product.
How is beta-glucan measured in reishi extract?
Ask for the Megazyme enzymatic assay, which measures total glucan and subtracts alpha-glucan to give beta-glucan. A total polysaccharide figure by UV also counts starch and other sugars, so the two numbers are not interchangeable.
What is the difference between a hot water and a dual extract?
A hot water extract mainly captures the water soluble polysaccharides, including beta-glucans. A dual extract adds an ethanol step to capture triterpenes, then combines both into one powder. Dual extracts usually taste more bitter.
Why is reishi powder bitter?
The bitter taste comes mostly from triterpenes in the fruiting body. Taste is not a test, though, so ask for a triterpene result and method if your formula depends on them.
Is there a USP monograph for reishi?
Yes. The USP-NF has monographs for Ganoderma Lucidum Fruiting Body and for its powder. They require NLT 0.3% triterpenoic acids and NLT 0.7% water soluble polysaccharides, both by HPLC on the dried basis.
Why do reishi triterpene figures differ so much between suppliers?
The method changes the number. USP adds up ten named ganoderic and ganoderenic acids by HPLC, while UV total triterpene tests count a broader group. Compare lots only on the same method and basis.
What documents can I get with an order?
A certificate of analysis (COA) and a specification sheet ship with every order. An allergen statement and a safety data sheet may also be available, depending on the lot in inventory. Contact us to request them.
Can I get a sample before a bulk order?
