# Cordyceps (Cordyceps militaris & Cordyceps sinensis) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/cordyceps-cordyceps-militaris-and-cordyceps-sinensis **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-18 **Evidence Score:** 8 / 10 **Category:** Mushroom/Fungi **Also Known As:** Cordyceps militaris, Cordyceps sinensis, Yartsa Gunbu, Dong Chong Xia Cao, Caterpillar Fungus, Winter Worm Summer Grass, Ophiocordyceps sinensis ## Overview Cordyceps militaris and Cordyceps sinensis are medicinal fungi containing cordycepin and polysaccharides that enhance cellular energy production through improved [mitochondrial function](/ingredients/condition/energy). These [adaptogen](/ingredients/condition/stress)ic mushrooms increase ATP synthesis, oxygen utilization, and immune cell activity. ## Health Benefits - Boosts energy, endurance, and athletic performance by increasing cellular [ATP production](/ingredients/condition/energy) and improving oxygen utilization. - Enhances [immune function](/ingredients/condition/immune-support) by regulating [cytokine](/ingredients/condition/inflammation) activity and stimulating natural killer (NK) cell response. - Supports respiratory health by improving VO₂ max and lung capacity, making it ideal for altitude adaptation and physical exertion. - Slows cellular aging and promotes [longevity](/ingredients/condition/longevity) through potent [antioxidant activity](/ingredients/condition/antioxidant) and mitochondrial protection. - Helps the body adapt to stress and restore balance via its [adaptogen](/ingredients/condition/stress)ic effects on the endocrine and nervous systems. ## Mechanism of Action Cordyceps enhances cellular energy through cordycepin, which increases [ATP production](/ingredients/condition/energy) by optimizing mitochondrial respiration and oxygen utilization. The polysaccharides activate immune cells by stimulating macrophages and natural killer cells while modulating [cytokine](/ingredients/condition/inflammation) production. Additionally, adenosine compounds improve [cardiovascular](/ingredients/condition/heart-health) function by enhancing blood flow and oxygen delivery to tissues. ## Clinical Summary Human studies using 1-3 grams daily show 5-11% improvements in [VO₂ max](/ingredients/condition/energy) and endurance capacity within 6 weeks. Randomized controlled trials with 40-80 participants demonstrate enhanced immune markers including increased [NK cell](/ingredients/condition/immune-support) activity. Research on respiratory function shows improved lung capacity and reduced fatigue, though most studies are small-scale with 4-12 week durations requiring larger trials for definitive conclusions. ## Nutritional Profile - Cordycepin: A unique nucleoside compound that enhances oxygen efficiency and endurance while modulating immune responses. - Polysaccharides: Contribute to immune regulation, [energy production](/ingredients/condition/energy), and [anti-inflammatory](/ingredients/condition/inflammation) effects. - [Beta-Glucan](/ingredients/condition/immune-support)s: Strengthen immune defenses and help reduce systemic inflammation. - No significant macronutrient content; valued for its bioactive compounds. ## Dosage & Preparation - Supplements: Take 1,000–2,000 mg of a dual-extracted Cordyceps militaris or sinensis extract daily. - Powder: Mix into smoothies, elixirs, or pre-workout tonics for energy and performance support. - Capsules: Use standardized extracts for consistent dosing of cordycepin and polysaccharides. ## Safety & Drug Interactions Cordyceps is generally well-tolerated with mild side effects including nausea, diarrhea, or dry mouth in sensitive individuals. It may enhance the effects of immunosuppressive medications and could interact with anticoagulant drugs due to adenosine content. Individuals with autoimmune conditions should exercise caution as cordyceps stimulates immune activity. Safety during pregnancy and breastfeeding has not been established, so avoidance is recommended. ## Scientific Research Clinical studies support Cordyceps’ efficacy in enhancing endurance, improving VO₂ max, reducing fatigue, and modulating immune markers. Cordycepin and fungal polysaccharides have been shown to improve [mitochondrial function](/ingredients/condition/energy), reduce [inflammation](/ingredients/condition/inflammation), and increase ATP production.

Its reputation as a revitalizing tonic was recorded in the Qing dynasty pharmacopeia and continues in modern [adaptogen](/ingredients/condition/stress)ic formulations. ## Synergistic Combinations Hermetica Synergy Stack (Formulation Heuristic) Role: Myco-adaptogenic base (immuno-metabolic support) Intention: Energy & [Metabolism](/ingredients/condition/weight-management) | Immune & [Inflammation](/ingredients/condition/inflammation) Primary Pairings: [Adaptogenic Herb](/ingredients/condition/stress) Tonic; Panax Ginseng (Asian Ginseng); Schisandra Berry Evidence: see study_urls / reference_urls ## Frequently Asked Questions ### How much cordyceps should I take daily? Clinical studies typically use 1-3 grams of cordyceps extract daily, divided into 2-3 doses with meals. For athletic performance, 3 grams daily appears most effective, while 1 gram may suffice for general immune support. ### What's the difference between Cordyceps militaris and sinensis? Cordyceps sinensis is the traditional wild variety found in Tibet, while Cordyceps militaris is cultivated and contains higher levels of cordycepin. Both provide similar benefits, but militaris is more sustainable and affordable. ### How long does cordyceps take to work? Energy and endurance improvements may be noticed within 1-2 weeks of consistent use. Immune system benefits typically develop over 4-6 weeks, while respiratory improvements often require 6-8 weeks of regular supplementation. ### Can I take cordyceps with coffee or pre-workout? Yes, cordyceps can be combined with caffeine and is often included in pre-workout formulas. The combination may enhance energy and endurance synergistically, though start with lower doses to assess tolerance. ### Does cordyceps help with altitude sickness? Traditional use and preliminary studies suggest cordyceps may help with altitude adaptation by improving oxygen utilization and reducing fatigue. However, robust clinical trials specifically for altitude sickness prevention are still needed. ### Is cordyceps safe to take during pregnancy or while breastfeeding? Cordyceps safety during pregnancy and breastfeeding has not been extensively studied in human clinical trials, so it is generally recommended to avoid supplementation during these periods unless explicitly approved by a healthcare provider. While cordyceps is considered a traditional food in some cultures, the concentrated supplement forms used today differ from culinary amounts, and the potential effects on fetal development or breast milk composition remain unclear. Always consult with an obstetrician or midwife before using cordyceps during pregnancy or lactation. ### What does scientific research show about cordyceps and athletic performance? Clinical studies demonstrate that cordyceps supplementation may improve aerobic endurance, VO₂ max, and ATP production—particularly in trained athletes and at altitudes where oxygen availability is limited. A landmark study published in the Journal of Alternative and Complementary Medicine showed modest improvements in oxygen utilization and exercise tolerance in healthy adults after 12 weeks of cordyceps use. However, results are mixed across studies, with benefits more pronounced in endurance athletes than in strength-focused activities, and some studies show minimal effects compared to placebo. ### Does cordyceps interact with blood pressure medications or stimulant drugs? Cordyceps may have mild cardiovascular and stimulant properties, so combining it with blood pressure medications, cardiac drugs, or prescription stimulants (such as those for ADHD) could theoretically potentiate effects and require dose adjustments. There is limited clinical data on specific drug-cordyceps interactions, making consultation with a pharmacist or physician essential before combining cordyceps with prescription medications. Individuals on anticoagulants should also exercise caution, as some research suggests cordyceps may have mild antiplatelet properties. ## References PubMed studies on Cordyceps and endurance, mitochondrial health, and immunity; Traditional Chinese and Tibetan medical texts; pharmacological reviews of cordycepin and fungal beta-glucans; clinical trials on VO₂ max and performance markers --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
