Bulk Chaga Mushroom Powder and Extract for Supplement Manufacturing
Chaga powder is a dried, milled ingredient made from the sclerotium of Inonotus obliquus, the black, cracked growth that forms on living birch trees. It is sold as milled whole chaga or as a hot water extract. Buyers specify it by material, origin, beta-glucan content, and oxalate content. We supply it in bulk to supplement brands, contract manufacturers, and formulators, with lot documents for your quality team.
A wild birch fungus with a clear material and origin story
Chaga is easy to specify once you confirm the material, where it was harvested, and how beta-glucan was measured. Those details make lots comparable from one supplier to the next.
A sclerotium, not a cap
The chaga you buy is a sterile sclerotium: a hard mass with a black, cracked crust and a rust brown interior. Some spec sheets call it a fruiting body, so ask which material is in the bag.
Harvested from birch
Chaga grows on living birch in cold northern forests. Named origins include Russia, Finland, Canada, and the northern United States. Ask for the country and region on each lot.
A measurable beta-glucan figure
Hot water extracts carry a stated beta-glucan minimum, often 10 to 30%. The Megazyme enzymatic method reports beta-glucan and alpha-glucan separately, which gives you a clean number to compare.
Compounds from the birch host
Chaga carries birch derived triterpenes such as betulin and betulinic acid, plus inotodiol and dark pigments. Some suppliers report betulinic acid by HPLC as part of their identity file.
Dark extract that mixes well in water
Hot water extracts are dark brown to black, fine, and dissolve in water. Milled whole chaga is coarser, more fibrous, and suits capsules, tablets, and tea blends.
Oxalate as a spec line
Chaga naturally contains oxalic acid, and levels differ between lots and suppliers. Many buyers add an oxalate result and a maximum to their specification.
Where formulators use chaga 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 and tea bags
- 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. If your spec sets an oxalate maximum, run the same math for oxalate per serving before you lock the formula.
What to check before you buy chaga powder
Two chaga ingredients with the same name can differ in material, origin, extraction, and composition. Review these points together, and ask for lot documents before you approve a supplier.
Wild sclerotium or cultivated mycelium
Confirm whether the powder is wild chaga sclerotium or mycelium grown on grain. The spec sheet and certificate of analysis (COA) should name the same material.
Origin and harvest records
Ask for the country, region, and host tree, plus how the harvest was managed. Wild material should come with collection records you can file.
Beta-glucan and alpha-glucan
Ask for both by the Megazyme enzymatic method. A high alpha-glucan result can point to grain substrate or an added starch carrier.
Oxalate result
Ask for oxalate by HPLC or ion chromatography on each COA, and set a maximum in your specification. Results vary between suppliers.
Extraction, ratio, and carrier
Confirm the solvent (usually hot water), the native extract ratio, and whether dextrin, maltodextrin, or another carrier is added.
Contaminants and radionuclides
Check heavy metals by ICP-MS, microbial limits, and pesticide residues. For Russian and Nordic lots, ask for cesium-137 and strontium-90 results.
Label wording: Name the material on your label to match the COA, for example chaga (Inonotus obliquus) sclerotium. Settle the exact wording with your regulatory team.
Typical specification for chaga extract
These values reflect a common hot water extract of wild chaga sclerotium. Milled whole chaga has its own spec. Final figures come from the specification sheet and COA for your lot. NLT means not less than, and NMT means not more than.

Storage and handling for bulk chaga 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.
Chaga buyer FAQ
Quick answers to the questions procurement and quality teams ask most.
What part of chaga is used in chaga powder?
Chaga powder is made from the sclerotium, the hard black growth that forms on living birch. It is not a cap and stem mushroom, so a spec sheet that says fruiting body is worth a follow up question.
Is chaga wild harvested or cultivated?
Most bulk chaga is wild harvested from birch forests, though some suppliers sell chaga mycelium grown on grain. Ask which one you are buying, because the two differ in composition. The source of each lot is provided with your quote.
How is beta-glucan measured in chaga 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.
Does chaga contain oxalate?
Yes. Chaga naturally contains oxalic acid, and levels differ between lots and suppliers. Ask for an oxalate result on the COA and set a maximum in your spec.
Where does bulk chaga come from?
Bulk chaga comes from birch forests in cold northern regions, including Russia, Finland, Canada, and the northern United States. Ask for the country and region on each lot.
What documents can I get with an order?
Select testing documents on the quote form and we will send what is available for the lot.
Can I get a sample before a bulk order?
Yes. Choose sample options on the quote form and we will confirm size and timing.
How should I store an opened bag?
Close the liner, press out the air, and keep the bag in a cool, dry place away from light. Use the powder within the shelf life shown on the COA.
