Cordyceps militaris is a fungus best known for its slender, bright orange, club-shaped fruiting bodies. It is one of the few Cordyceps species that can be grown reliably indoors, which is why it is now widely used in foods and supplements. This introduction covers what it is, where it comes from, and what it contains.
Where Cordyceps militaris fits in the fungal family tree
C. militaris belongs to the order Hypocreales and the family Cordycipitaceae. It is the type species of the genus Cordyceps.1 In 2007 a large molecular study reorganised these fungi and moved the Himalayan caterpillar fungus — once called Cordyceps sinensis, and known in India as Kida Jadi — into a separate genus, Ophiocordyceps, in a different family.1 So when people say "Cordyceps" they may mean either species; they are related, but not the same. See Cordyceps militaris vs Cordyceps sinensis.
How it grows in nature
In the wild, C. militaris is an insect-parasitic fungus. Its spores infect the larvae or pupae of moths and butterflies; the fungus grows through the host and later sends up orange fruiting bodies from it. It occurs in forests across much of the Northern Hemisphere.
How it is grown for food
Unlike the caterpillar fungus, C. militaris forms fruiting bodies on a prepared substrate, without an insect. Growers typically start with a liquid culture, inoculate containers of grain-based substrate, keep them dark while the mycelium spreads, and then use light–dark cycles to trigger fruiting.2 We describe how we do this in Indore in our Cordyceps militaris guide.
Why is it orange?
The colour comes from naturally occurring carotenoid pigments in the fruiting body. Light exposure during cultivation influences how much pigment develops, which is one reason fruiting is done under controlled lighting.2
What does it contain?
Researchers have identified several naturally occurring compounds in C. militaris:3
- Cordycepin (3′-deoxyadenosine) – a nucleoside related to adenosine and the compound most associated with C. militaris research.
- Adenosine – a nucleoside found in all living cells.
- Polysaccharides – complex carbohydrates from the fungal cell wall.
- D-mannitol – a sugar alcohol, historically called "cordycepic acid".
- Ergosterol – a fungal sterol.
Levels vary with strain, substrate, light and temperature,2 and most studies of these compounds have been carried out in cells and animals rather than people.3
How people use it
C. militaris fruiting bodies have a mild, savoury taste. They are eaten dried, steeped in warm water or tea, added to soups, or taken as extracts in capsules and liquids. Cordygen offers three formats, all made from cultivated fruiting bodies: Cordygen Raw (whole dried fruiting body), Vital Capsules and the Tincture (fruiting-body extract). Compare them in Raw, Capsules or Tincture.

How Cordyceps militaris is grown
Unlike its wild cousin, Cordyceps militaris does not need a caterpillar, a mountain, or luck. It is cultivated indoors under controlled conditions: a mother culture is prepared in a lab, grain-based substrate is sterilised and inoculated, and the jars or trays are kept at carefully managed temperature, humidity and light. Over the following weeks the mycelium colonises the substrate, and then the bright orange fruiting bodies — the part you actually eat — grow out and are harvested at maturity, dried, and packed.
This is why cultivated Cordyceps militaris is consistent and affordable while wild Cordyceps sinensis is neither. Every batch starts from the same culture and the same process, so what is in the jar this month matches what was in the jar last month.

Fruiting body vs mycelium — why the difference matters
When you buy a Cordyceps product, you are usually buying one of two very different things. The fruiting body is the visible mushroom — the orange structure that grows above the surface. Mycelium is the thread-like root network underneath, and in cheap products it is often sold still mixed with the grain it grew on, which means a large part of the capsule can be grain starch rather than fungus.
Cordygen's Raw is 100% fruiting body — nothing else in the jar. If you want the full comparison before you buy anything, read Cordyceps fruiting body vs mycelium.
Militaris vs sinensis — and where Kida Jadi fits
"Kida Jadi" is the name most Indians know: it traditionally refers to wild Ophiocordyceps sinensis, the caterpillar fungus collected in the high Himalaya and sold at extraordinary prices. Cordyceps militaris is a different species in the same broader family — one that can be cultivated, and the one modern research and supplements mostly use, because it reliably produces the compounds people are interested in, including cordycepin.
We have written both comparisons in full: Cordyceps militaris vs Cordyceps sinensis and wild Kida Jadi vs cultivated Cordyceps. For the complete story of the name itself, see our Kida Jadi page.
The compounds researchers study: cordycepin and adenosine
Two naturally occurring compounds explain most of the scientific interest in this mushroom. Cordycepin is found in meaningful amounts mainly in Cordyceps militaris, and adenosine is a building block involved in the body's energy systems. Cordygen's Raw lists its label facts openly: per 100 g it provides 28.6 g protein, 5.8 g natural beta-glucans and cordycepin of approximately >0.1 g.
A note on honesty, because it matters in this category: these compounds are studied, and traditional use is long — but a supplement is not a medicine, and we do not claim that Cordyceps treats or cures any disease. What we claim is narrower and verifiable: species, form, weight and label facts, exactly as printed.
Raw, capsules or tincture — which form suits you?
All three Cordygen formats start from the same cultivated Cordyceps militaris; they differ in how they fit into a day. Raw (30 g dried fruiting body, ₹3,499) is the whole mushroom — take 1–2 g directly, or add it to warm water, tea or food. Vital Capsules (60 vegetarian capsules of 500 mg extract, ₹1,999) are the no-measure option: one capsule twice a day with water after meals. The Tincture (30 ml liquid extract, 1:5, ₹2,499) suits people who prefer drops — 1–2 ml under the tongue or in water, once or twice a day.
Still deciding? Our guide to choosing your Cordygen format walks through taste, routine and cost per day for each.
Quick answers
Is Cordyceps militaris the same as Kida Jadi? Not exactly. Kida Jadi traditionally means the wild sinensis caterpillar fungus. Militaris is its cultivated relative — a different species, grown indoors, and the one used in most modern supplements, including ours.
How do I take it? Raw: 1–2 g daily, directly or in warm water or food. Capsules: one capsule twice daily after meals. Tincture: 1–2 ml (20–40 drops), once or twice daily. These are the suggested uses printed on our labels.
How long before I notice anything? A supplement is a daily ritual, not a dose of medicine. Most people judge any supplement over a few consistent weeks — and if you have a medical condition or take medication, speak to your doctor first.
Where is Cordygen made? The Cordyceps is cultivated in India and packed in Rau, Indore, Madhya Pradesh, by Shnikh Agrobiotech Private Limited (FSSAI Reg. No. 21426850004712).
Why athletes and busy people are interested in it
Most modern interest in Cordyceps comes from two directions. The first is tradition: in Chinese and Tibetan practice, Cordyceps has been used for centuries as a tonic associated with stamina and recovery. The second is laboratory research, which has looked at Cordyceps in relation to exercise capacity and the body's energy pathways — adenosine, one of its natural compounds, is part of how cells handle energy (it sits inside ATP, the molecule your muscles spend when they work).
The honest summary is this: the research is promising enough that scientists keep studying it, and small enough that nobody should promise you a transformation. If a seller guarantees performance results from any mushroom, that is a marketing claim, not a scientific one. What a good product can honestly offer is the right species, the right part of the fungus, a clear label, and a format you will actually take every day — because consistency is the part of the equation that is fully in your hands.
How to choose a good Cordyceps product in India
Whether you buy from us or anyone else, this five-point check will protect you:
1. Species named. The label should say Cordyceps militaris (cultivated) or Ophiocordyceps sinensis (wild). Just "Cordyceps" with no species is a red flag.
2. Part named. Fruiting body, mycelium, or extract — and if it is an extract, the ratio (ours is 1:5 for the tincture). "Myceliated grain" products are largely grain.
3. Weight and serving maths that add up. A 30 g jar at 1–2 g a day lasts 15–30 days. If the price looks impossibly low for the quantity, the quantity is probably not what you think it is.
4. A real maker. Look for a manufacturer name, address and FSSAI number on the pack. Ours: Shnikh Agrobiotech Private Limited, Rau, Indore — FSSAI Reg. No. 21426850004712.
5. Claims you can verify. Prefer labels that list measurable facts (protein, beta-glucans, cordycepin) over labels that promise cures. Our full label facts are on the Quality & Transparency page.
