Chaga growing on a birch trunk in the forest

Buying chaga wholesale: powder, extract, capsules and tincture for supplement brands

Short answer: chaga (Inonotus obliquus) is bought in bulk as ground powder, extract powder, capsules with ground chaga, extract capsules and liquid extract (tincture). In the EU, chaga and its water and ethanol extracts are listed as not novel in food supplements, so chaga is a raw material for supplement brands; other food uses may need a novel food authorisation. GOA Supply supplies all five forms wholesale and as private label, from 10 kg of powder, 20,000 capsules or 100 bottles.

What is chaga?

Chaga is the common name of Inonotus obliquus, a fungus that grows on birch trees. Its English name in the EU Novel Food Catalogue, cinder conk, refers to the black, charcoal-like growth it forms on the trunk. For supplements, the harvested material is dried and then either ground into a powder or extracted. An extract is made with water, ethanol or both, and is then dried into a powder or kept as a liquid extract (tincture). Ground chaga contains the whole dried material; an extract contains the soluble part in concentrated form.

What to check when you buy chaga in bulk

  • The part named in the specification. Regulators describe chaga in different terms. The EU catalogue speaks of the fruiting body, while the French database Compl'Alim lists thallus, carpophore (fruiting body), mycelium and sclerotium separately, with different statuses (see below). Make sure the specification names the part and that it matches what you declare.
  • Ground or extract. Ground chaga is the dried material as such. An extract is concentrated and is usually described by an extract ratio, such as 10:1, or by a percentage of a marker group such as polysaccharides. Ask for the ratio or marker and the analytical method; for our extracts this is in the specification.
  • Solvent. The EU catalogue entry covers water and ethanol extracts. Check which solvent was used, especially for a tincture, where the liquid base is part of the composition.
  • Particle size. For capsule filling, ask for the mesh or particle size, since it affects flow in the capsule machine and the fill weight per capsule.
  • Documents. Ask for the specification, a certificate of analysis (CoA) per batch, and results for pesticide residues, heavy metals and microbiology where relevant. For our chaga products, the specification and CoA are available on request.
  • Organic. GOA Supply is organic certified (NL-BIO-01) and our ground chaga powder is organic. If you sell it as organic, check with your control body whether your own packing and labelling need certification under Regulation (EU) 2018/848.

EU regulation: chaga is limited to food supplements

The EU Novel Food Catalogue entry for Inonotus obliquus (checked on 10 November 2026) covers the fruiting body and its water and ethanol extracts, liquid or dried. Their status is not novel in food supplements. This means they were used in food supplements in the EU before 15 May 1997 and need no authorisation for that use. Other food uses, for example in drinks, bars or bakery products, may be considered novel and would then need an authorisation under Regulation (EU) 2015/2283. Competent authorities in Finland and the Czech Republic also concluded that two specific water-based extracts of the fruiting body are not novel in food supplements.

In France, Compl'Alim lists Inonotus obliquus as authorised in food supplements, with the thallus and the carpophore authorised and the mycelium and sclerotium listed as not authorised. If you plan to sell in France, ask your supplier which of these terms applies to the raw material before you file your Compl'Alim declaration.

  • the label, in a language that consumers in each country of sale easily understand;
  • the claims, which must comply with Regulation (EC) No 1924/2006;
  • national notification: none for food supplements in the Netherlands, a notification file via FOODSUP of the FPS Public Health in Belgium, a declaration via Compl'Alim in France and a notification to the BVL in Germany at the latest when the product is first placed on the market (§ 5 NemV).

FAQ

Can I use chaga in drinks or other foods?
Not without checking first. The EU catalogue lists chaga as not novel in food supplements only. Use in other foods may be novel and need an EU authorisation, so our chaga is offered as a raw material for food supplements.

Is chaga allowed in food supplements in France?
Yes, Compl'Alim lists Inonotus obliquus as authorised. The thallus and carpophore are authorised, while the mycelium and sclerotium are listed as not authorised, so check the part named in your specification.

What is the difference between chaga powder and chaga extract?
Chaga powder is the dried, ground material. Chaga extract is made with water and/or ethanol and dried, so it is a concentrate with a stated extract ratio or marker content.

What is in your chaga tincture?
A liquid extract of Inonotus obliquus in 60 ml bottles, with China as country of origin. The full composition, including the extraction solvent, is available on request.
