Cordyceps supplements usually come in one of two forms: CS-4, a cultivated mycelium strain of Cordyceps sinensis, and Cordyceps militaris, a species that can produce real fruiting bodies when cultivated. They are not interchangeable, which is why our Super Cordyceps combines both: a 10:1 CS-4 extract with low-temperature Militaris powder. Here is what each one is, how they differ, and what to check on any cordyceps label.
Quick answer
- CS-4 is a fermented mycelium strain developed to stand in for wild Cordyceps sinensis, which is rare and expensive.
- Cordyceps militaris is a different species that can be grown to fruiting body on a cultivated medium, and it is a natural source of the compound cordycepin.
- Because the two forms have different compound profiles, combining them gives a broader cordyceps product than either alone.
- Whatever you buy, check the species, the part used (mycelium or fruiting body) and any extraction ratio on the label.
Why wild cordyceps isn't in your supplement
Traditional cordyceps, now classified as Ophiocordyceps sinensis, grows wild at high altitudes on the Tibetan Plateau. It has been used in traditional Chinese medicine for centuries as a tonic for energy, stamina, and lung and kidney health. Wild harvests are small and in high demand, which makes genuine wild cordyceps far too scarce and costly for an everyday supplement.
That gap is why cultivated cordyceps exists. Nearly every cordyceps supplement sold today is made from one of the two cultivated forms below.
What is CS-4?
CS-4 is a strain of cordyceps mycelium, the root-like network of the fungus, grown by fermentation. It was developed as a consistent, cultivated alternative to wild Cordyceps sinensis, and it has been the subject of much of the modern research on cordyceps.
In Super Cordyceps, we use CS-4 as a 10:1 extract, meaning the mycelium is concentrated rather than simply dried and ground.
What is Cordyceps militaris?
Cordyceps militaris is a separate species. Unlike sinensis, militaris can be grown all the way to its fruiting body (the mushroom itself) on a cultivated medium. It is also a natural source of cordycepin, one of the most studied compounds in cordyceps.
We use militaris as a low-temperature whole powder of fruiting body and mycelium, so it stays a whole food rather than an isolated extract.
CS-4 vs. Militaris at a glance
| CS-4 | Cordyceps militaris | |
|---|---|---|
| What it is | Cultivated mycelium strain of C. sinensis | Separate cordyceps species |
| Part used | Mycelium | Fruiting body (and mycelium) |
| How it's grown | Fermentation | Cultivated medium |
| Known for | The bulk of modern cordyceps research | Natural cordycepin content |
| In Super Cordyceps | 10:1 extract | Low-temperature whole powder (organic) |
Why we use both
When we formulated Super Cordyceps, the question wasn't which form was "better." Each one brings something the other doesn't: CS-4 carries the research history and a concentrated extract, while militaris adds a true fruiting body and its own compound profile. Combining them gives a more balanced cordyceps than choosing one.
In traditional terms, well-balanced cordyceps supports both yin and yang, which is part of why it has long been used as a daily tonic rather than an occasional one.
“This extract is magnificent in more ways than one and it actually tastes nice!”

What to check on any cordyceps label
- Species: sinensis (usually CS-4), militaris, or both.
- Part used: mycelium, fruiting body, or a mix. Mycelium grown on grain can carry grain starch with it, so a stated extraction or whole-food process matters.
- Extraction: a stated ratio, like 10:1, tells you the material was concentrated.
- Organic sourcing and a short, fully disclosed ingredient list.
How to take Super Cordyceps
Mix ½ to 1 heaping teaspoon, one or two times a day, into water, tea, coffee or another favorite drink. Many customers stir it into their morning coffee or a cup of Heavenly Hot Chocolate. If you're pregnant, nursing or taking medication, check with your healthcare provider first.
FAQ
Is CS-4 real cordyceps?
Yes. CS-4 is a cultivated strain of cordyceps mycelium developed as an alternative to scarce wild Cordyceps sinensis. It is not the wild mushroom, but it is genuine cordyceps fungus.
Which is better, CS-4 or Cordyceps militaris?
Neither is simply better. CS-4 is a concentrated mycelium extract with a long research history; militaris provides a true fruiting body and natural cordycepin. That is why Super Cordyceps combines the two.
What is cordycepin?
Cordycepin is a naturally occurring compound found in Cordyceps militaris and one of the most studied compounds in cordyceps research.
How much cordyceps should I take?
For Super Cordyceps, the label suggests ½ to 1 heaping teaspoon, one or two times a day, mixed into a drink.
Can I add cordyceps to coffee?
Yes. Super Cordyceps mixes into coffee, tea, hot chocolate or plain water.
