What Is Cordyceps?

Cordyceps is a genus of parasitic fungi that has been used in traditional Chinese and Tibetan medicine for centuries. The most well-known species is Cordyceps sinensis, though Cordyceps militaris is now commonly cultivated for supplements due to the rarity and expense of wild Cordyceps sinensis.

Unlike other functional mushrooms, cordyceps has a unique lifecycle in nature, growing from insect larvae in high-altitude regions of the Himalayas. Today, modern cultivation methods produce cordyceps without involving insects, making it sustainable and accessible for wellness applications.

Cordyceps has gained attention in Western wellness circles primarily for its potential to support energy levels, athletic performance, and stamina. Many users combine cordyceps with CBD hemp products to create a balanced approach to energy and recovery.

Cordyceps Benefits: The Science Behind the Energy Boost

ATP Production and Cellular Energy

One of the primary mechanisms by which cordyceps may support energy is through enhanced ATP (adenosine triphosphate) production. ATP is the primary energy currency of cells, and research suggests cordyceps compounds may help optimize its production and utilization.

A study published in the Journal of Alternative and Complementary Medicine found that supplementation with Cordyceps sinensis improved cellular energy metabolism in healthy older adults. Participants showed increased metabolic threshold and ventilatory threshold, indicators of improved energy efficiency.

Research on animal models has demonstrated that cordyceps can increase ATP levels in the liver by up to 45-55%, suggesting a significant impact on energy metabolism at the cellular level.

Athletic Performance and Endurance

Cordyceps has become popular among athletes and fitness enthusiasts for its potential to enhance physical performance. Several studies have examined its effects on exercise capacity:

A 2010 double-blind, placebo-controlled study investigated the effects of Cordyceps militaris supplementation on exercise performance in healthy young adults. After three weeks, participants taking cordyceps showed improved oxygen uptake and time to exhaustion during high-intensity exercise.

Another study involving older adults found that those who took cordyceps extract for 12 weeks showed significant improvements in exercise performance and overall vitality compared to the placebo group. Participants reported feeling less fatigued and more energetic during daily activities.

Research suggests cordyceps may enhance performance by improving the way the body uses oxygen, increasing blood flow, and supporting mitochondrial function. These mechanisms could explain why many athletes incorporate cordyceps into their performance supplement routines.

Oxygen Utilization and VO2 Max

One of the most studied benefits of cordyceps is its potential effect on oxygen utilization. VO2 max, which measures the maximum amount of oxygen the body can use during exercise, is a key indicator of cardiovascular fitness and endurance capacity.

Multiple studies have shown that cordyceps supplementation may improve VO2 max and other markers of oxygen efficiency. A 2016 study found that trained athletes taking Cordyceps militaris for one week showed improved ventilatory threshold and time to exhaustion, suggesting enhanced oxygen utilization during intense exercise.

The mechanism appears to involve increased production of adenosine, a compound that helps dilate blood vessels and improve oxygen delivery to tissues. This could explain the energizing effects many users experience.

Stamina and Fatigue Resistance

Beyond immediate energy boosts, cordyceps has been investigated for its potential to reduce fatigue and improve stamina over time. Research on animal models has consistently shown anti-fatigue effects:

Studies on mice have demonstrated that cordyceps extract can significantly extend swimming time to exhaustion and reduce lactate accumulation in muscles. These effects suggest improved endurance and faster recovery from physical exertion.

Human research supports these findings. A 2016 systematic review of multiple clinical trials concluded that cordyceps supplementation appears to improve exercise performance, particularly in untrained individuals, though effects in elite athletes showed mixed results.

Recovery and Muscle Function

Emerging research suggests cordyceps may also support post-exercise recovery and muscle function. The mushroom's bioactive compounds appear to have anti-inflammatory properties that could help reduce exercise-induced muscle damage.

A study on mice found that cordyceps extract helped protect against skeletal muscle injury and improved recovery markers after intense exercise. While human research in this area is limited, these findings suggest potential benefits for athletic recovery and muscle preservation.

How Cordyceps Works: Mechanisms of Action

Adaptogenic Properties

Cordyceps is classified as an adaptogen, a class of substances that help the body adapt to various stressors. Adaptogens work by modulating the hypothalamic-pituitary-adrenal (HPA) axis, which regulates stress response and energy balance.

Unlike stimulants that provide temporary energy followed by a crash, adaptogens like cordyceps support more sustainable energy by helping normalize physiological functions. This may explain why many users report feeling energized without experiencing jitters or anxiety.

Antioxidant Activity

Cordyceps contains various antioxidant compounds that help protect cells from oxidative stress. During intense physical activity, the body produces free radicals that can damage cells and contribute to fatigue. The antioxidant properties of cordyceps may help counter this effect.

Research has shown that cordyceps extract exhibits significant antioxidant activity in laboratory studies, potentially protecting mitochondria (the energy-producing structures in cells) from oxidative damage and supporting sustained energy production.

Blood Sugar Regulation

Some research suggests cordyceps may help regulate blood sugar levels, which could contribute to more stable energy throughout the day. Animal studies have shown that cordyceps compounds can improve insulin sensitivity and glucose metabolism.

By supporting balanced blood sugar, cordyceps may help prevent the energy crashes associated with blood sugar fluctuations, contributing to more consistent energy levels.

Cordyceps Dosage and How to Use It

Recommended Dosage

Research studies have used varying doses of cordyceps, typically ranging from 1,000 mg to 3,000 mg per day. The optimal dose may depend on several factors:

• Product type: Extracts are more concentrated than raw powder, requiring lower doses
• Species: Cordyceps sinensis and Cordyceps militaris may have different potencies
• Individual goals: Athletic performance enhancement may require higher doses than general wellness support
• Body weight and metabolism: Larger individuals may benefit from higher doses

Many functional mushroom supplements provide dosage guidelines on their labels. Starting with a lower dose and gradually increasing allows you to assess your individual response.

Timing and Duration

For energy and performance benefits, cordyceps is typically taken in the morning or 30-60 minutes before exercise. Taking it earlier in the day helps avoid any potential interference with sleep, though cordyceps is generally not as stimulating as caffeine.

Research suggests that benefits may accumulate over time. While some users report feeling effects within days, most studies showing significant performance improvements used supplementation periods of at least 2-3 weeks.

Forms of Cordyceps

Cordyceps is available in several supplemental forms:

Capsules: Convenient and provide precise dosing of powdered or extracted cordyceps.

Powder: Can be mixed into smoothies, coffee, or pre-workout drinks. Offers flexibility in dosing but may have an earthy taste.

Gummies: An enjoyable way to take cordyceps, often combined with other functional ingredients in Field Operator products.

Tinctures: Liquid extracts that may be absorbed more quickly than capsules or powder.

Cordyceps for Different Goals

Athletic Performance

Athletes and fitness enthusiasts typically use cordyceps to enhance workout performance and endurance. The research-backed protocol involves taking 1,000-3,000 mg daily for at least 2-3 weeks before expecting significant performance improvements.

Many athletes take cordyceps 30-60 minutes before training sessions, though consistent daily supplementation appears more effective than pre-workout use alone.

Daily Energy and Productivity

For general energy support and combating fatigue, a moderate dose (1,000-1,500 mg) taken in the morning may be effective. This approach supports sustained energy throughout the day without the jitters associated with excessive caffeine.

Some users combine cordyceps with CBD gummies to balance energizing effects with stress management, creating a focused yet calm state ideal for productivity.

Aging and Vitality

Research on older adults suggests cordyceps may help combat age-related decline in energy and vitality. Studies showing benefits in elderly populations typically used doses of 1,000-3,000 mg daily for extended periods (12 weeks or more).

The anti-fatigue and energy-supporting effects of cordyceps may be particularly valuable for maintaining an active lifestyle as we age.

Combining Cordyceps with Other Supplements

Cordyceps and CBD

The combination of cordyceps and CBD has become increasingly popular for active lifestyles. While cordyceps supports energy and performance, CBD may help with post-workout recovery, muscle soreness, and sleep quality.

This pairing creates a comprehensive approach to fitness: cordyceps for performance and energy, CBD for recovery and rest. Many users take cordyceps in the morning and CBD in the evening.
