Exactly how much cordyceps is in our product, straight from the label.
How to use it (label directions): Forage: follow the directions on the label. Each bottle holds 30 servings. How this compares with research doses: human exercise and immune trials have used about 1 to 4 g a day of cordyceps preparations. An 8:1 extract is concentrated, but amounts are not directly comparable with those studies. Use it as directed on the label.
Energy From the Cell, Not the Nerves
Cordyceps has traveled a long way: from a high-altitude folk remedy to one of the most studied performance-support mushrooms in modern research. Today it is prized for something specific, smoother energy, better endurance, and faster recovery, without stimulants.
Rather than pushing your nervous system the way caffeine does, cordyceps works deeper in the cell, on mitochondrial function, oxygen use, immune balance, and cellular protection. This guide walks through what it is, the compounds that make it work, how to dose it, and how to choose a quality extract.
What Is Cordyceps militaris?
Cordyceps is a genus of fungi traditionally used in Tibetan and Chinese practices. The wild species Ophiocordyceps sinensis is rare and expensive, so Cordyceps militaris has become the modern supplement standard. In nature it is an entomopathogenic fungus that grows on insect larvae, but modern cultivation on plant-based substrates has changed that entirely.
Growing C. militaris on plant-based media offers three clear advantages, and makes vegan-friendly products possible:
- Consistency in bioactive compound levels
- Higher cordycepin content than many wild varieties
- Reduced environmental contamination
Key Bioactive Compounds
Cordyceps works through a group of active compounds that act together on metabolic, immune, and antioxidant pathways.
Nucleosides: Cordycepin and Adenosine
Cordycepin is a structural cousin of adenosine, linked to ATP dynamics, nitric oxide signaling, and performance support. It also appears in research on anti-inflammatory activity.
Polysaccharides and D-Mannitol
The polysaccharides (IPS and EPS) are complex sugar chains that support immune activation and antioxidant activity. D-mannitol, also called cordycepic acid, works as an osmotic agent and a carbohydrate reserve.
Ergothioneine and GABA
Ergothioneine is a sulfur-containing amino acid with strong antioxidant and cell-protective effects that accumulates in tissues and declines with age. GABA, the brain's main inhibitory neurotransmitter, is involved in the stress response and sleep.
Antioxidants and Peptides
Cordyceps also contains phenolic compounds, carotenoids, peptides such as cordymin, and a range of vitamins and minerals.
| Compound Group | Key Examples | What They Support |
|---|---|---|
| Nucleosides | Cordycepin, adenosine | ATP support, nitric oxide signaling, cellular protection |
| Polysaccharides | IPS, EPS | Immune modulation, antioxidant activity, metabolic support |
| Small molecules | D-mannitol | Osmotic balance, cellular stress resilience |
| Antioxidants | Ergothioneine, carotenoids | Oxidative stress balance, organ protection |
| Proteins and peptides | Cordymin, lectins | Immune modulation, antimicrobial activity |
How Cordyceps Works in Your Body
Mitochondrial Energy and ATP Production
Cordycepin and adenosine support the efficiency of ATP production and influence AMPK and AKT/mTOR signaling, the pathways that regulate energy balance and recovery inside cells. Because so much of how you feel traces back to mitochondrial function, small gains here can matter.
Oxygen Utilization and VO2 Pathways
Research suggests cordyceps can improve time to exhaustion and markers of oxygen efficiency. Studies on mushroom blends have shown increases in VO2 max and better tolerance to high-intensity exercise.
Nitric Oxide, Blood Flow, and Lactate Threshold
Cordycepin has been linked in research to increased nitric oxide, which supports blood flow, and to delayed lactate buildup during exercise, which may support a higher lactate threshold.
Metabolic Flexibility
Cordyceps supports more efficient switching between carbohydrate and fat fuel, and may help maintain healthy blood sugar and lipid balance.
Small improvements in mitochondrial function can lead to noticeable changes in fatigue and performance.
Energy, Endurance, and Recovery
Anti-Fatigue and Endurance Support
Animal studies consistently show longer endurance times, higher ATP and antioxidant enzyme activity, and lower lactate markers. Some human trials report improved VO2 max, better tolerance to high-intensity efforts, and delayed fatigue onset.
What It Means in Real Life
For most people, consistent cordyceps use may support sustained physical energy for training, travel, and long workdays, shorten recovery time, and reduce reliance on stimulants.
In trials, effects on stamina built gradually over several weeks rather than arriving all at once.
Immune, Inflammatory, and Antioxidant Support
Immune Modulation, Not Just Stimulation
Polysaccharides and cordycepin activate immune cells and increase signaling molecules, supporting a balanced rather than overdriven immune response. Human trials at around 1.5 g per day for several weeks have reported improved natural killer (NK) cell activity.
Anti-Inflammatory Pathways
In lab models, cordycepin suppresses inflammatory signals including NF-kB, COX-2, iNOS, and pro-inflammatory cytokines. Polysaccharides have also shown anti-inflammatory effects in animal studies.
Antioxidant Defense
Cordyceps supports both direct free-radical scavenging and the upregulation of your own antioxidant systems, including SOD, catalase, and glutathione peroxidase.
System-Wide Health Support
Metabolic and Cardiovascular Health
Data suggest cordyceps may support healthy blood sugar management, help maintain healthy triglycerides, total cholesterol, and LDL, and reduce platelet aggregation in animal models.
Brain and Nerve Protection
Animal models show improved memory and learning, and cordycepin has protected microglia in lab settings.
Liver and Kidney Support
Cordyceps has shown liver and kidney protective effects in animal models; human evidence here is limited.
Research-Studied Dosages
Cordyceps is dosed differently depending on whether you use a concentrated extract or whole mushroom powder. Frequently referenced research-backed ranges are:
Give it at least 3 to 4 weeks of consistent daily use before judging the effect, since the benefits build gradually. Forage provides 200 mg of cordyceps 8:1 extract per 2-capsule serving, below the research ranges above, as part of a multi-mushroom blend; take it as directed on the label.
Start low, go slow, and notice how your body responds.
Stacking Cordyceps With Other Mushrooms
Cordyceps and Lion's Mane for Brain and Performance
Lion's mane supports nerve growth factors and cognitive health, while cordyceps focuses on energy, oxygen use, and metabolic resilience. Used together, they cover both the mental and physical sides of performance.
Adaptogenic Mushroom Blends
Cordyceps pairs naturally with lion's mane, reishi, and chaga for whole-system resilience. This is exactly the approach behind our adaptogenic mushroom blend, which combines several targeted mushrooms in one formula.
Safety, Side Effects, and Who Should Be Cautious
Reported Side Effects
Cordyceps is generally well tolerated. When side effects occur they are typically mild and short-lived, and may include digestive discomfort, nausea, or loose stools. Taking it with food and starting at a lower dose can help.
Who Should Talk to a Clinician First?
Use caution and speak with a healthcare professional first if you are pregnant, breastfeeding, managing a medical condition (especially an autoimmune, bleeding, or metabolic disorder), or taking prescription medications.
If you would not be comfortable mentioning a supplement during a checkup, that is a sign to bring it up.
Why Our Cordyceps Is Different
Concentrated 8:1 Extract
Forage uses a concentrated cordyceps 8:1 fruiting body extract, 200 mg per 2-capsule serving.
Purity and Testing
Made with third-party tested ingredients.
Integrated Into Broader Energy and Recovery Systems
Rather than using cordyceps alone, Forage pairs it with six other functional mushrooms, Himalayan shilajit extract and ashwagandha root extract, so it works as part of a system rather than a single ingredient.
Non-Stimulant Performance, Built to Last.
Used consistently, cordyceps offers a non-stimulant path to better energy and resilience.
- Smoother, more sustained energy and endurance
- Better oxygen use and recovery capacity
- Support for immune balance, inflammation control, and antioxidant defense
- System-wide effects on metabolism, cardiovascular function, and cellular health
