Reishi and Cordyceps Supplements: Species, Markers and What Buyers Should Check

Functional mushroom capsules with dried mushrooms

After lion's mane, reishi and cordyceps are the functional mushrooms buyers ask about most. Mushroom supplements grew 76% in US mainstream stores in 2024, and they are among the trends European and UK retailers watch closely. Both mushrooms come in several forms, and the differences matter for quality, price and regulation.

In short: reishi (Ganoderma lucidum) is judged mainly by beta-glucans and triterpenes. Cordyceps is usually cultivated Cordyceps militaris or fermented CS-4 mycelium, not the rare wild Ophiocordyceps sinensis, and its markers are cordycepin and adenosine.

Key takeaways

  • Reishi extracts are specified by beta-glucans and triterpenes; the bitterness comes from triterpenes.
  • Most cordyceps supplements use cultivated Cordyceps militaris or CS-4, a fermented mycelium of a related fungus.
  • Cordycepin (in C. militaris) and adenosine are the usual cordyceps markers.
  • EU novel food status depends on species and form; some trade sources say C. militaris needs authorisation.

Reishi: what to look for

Reishi (Ganoderma lucidum) is a woody, glossy red mushroom used in East Asian traditions for centuries. Supplements use fruiting body powder, hot-water extracts (rich in beta-glucans) or dual extracts that also capture alcohol-soluble triterpenes. Spore powder is a separate product. Ask which form you are buying and for beta-glucan and triterpene figures by stated methods.

Cordyceps: three very different products

ProductWhat it isNotes
Wild Ophiocordyceps sinensisWild fungus from the Himalayan plateauExtremely expensive; rarely in supplements
CS-4 (fermented mycelium)Mycelium of a related fungus grown in tanksLong history in supplements
Cordyceps militarisCultivated fruiting bodyContains cordycepin; widely sold

A label that just says "cordyceps" does not tell the buyer which of these they are getting.

Markers and testing

  • Reishi: beta-glucans (enzymatic method), triterpenes, and a check for starch or alpha-glucans.
  • Cordyceps: cordycepin and adenosine by HPLC; adenosine is the quality indicator used for C. sinensis in the Chinese Pharmacopoeia.
  • Both: species identity, heavy metals (mushrooms can accumulate them), pesticides and microbiology.

Fruiting body vs mycelium

As with lion's mane, mycelium grown on grain can contain a lot of starch from the grain, which inflates "polysaccharide" figures. Fruiting body extracts usually have higher beta-glucans. Our fruiting body vs mycelium guide explains the tests in detail.

Rules by market

  • USA: dietary supplements under FDA GMP rules; no disease claims.
  • EU and UK: novel food status depends on species and form. Trade sources report that Cordyceps militaris requires novel food authorisation in the EU, while some mycelium forms have a longer history of use. Check the EU Novel Food Catalogue for your exact ingredient.
  • Brazil: check ANVISA's positive lists before launch.

Buyer checklist

  • Species, part (fruiting body, mycelium or spores) and substrate
  • Extraction method and ratio
  • Markers: beta-glucans and triterpenes for reishi; cordycepin and adenosine for cordyceps
  • Heavy metals and microbiology per batch
  • Novel food status checked for EU and UK sales
"Cordyceps" can mean a wild Himalayan fungus, a tank-grown mycelium or a cultivated mushroom. The label should say which.

FAQ

Reishi and Cordyceps Questions

Usually beta-glucans and triterpenes, with methods stated on the specification.

C. militaris is a cultivated fruiting body containing cordycepin; CS-4 is a fermented mycelium of a related fungus.

Rarely. Wild Ophiocordyceps sinensis is extremely expensive, so most products use cultivated or fermented forms.

A compound found in Cordyceps militaris, measured by HPLC as a quality marker.

Trade sources report it needs novel food authorisation. Check the EU Novel Food Catalogue for your ingredient.

Mushrooms can accumulate metals from their growing medium, so batch testing is important.
