What are the health benefits of Cordyceps mushrooms?

The Cordyceps mushroom is a functional fungus long valued in traditional Chinese medicine, now gaining wider recognition for its ability to support energy, aid exercise performance, promote recovery and offer overall nourishment to the body. 

Traditionally taken in forms like mushroom tinctures, powders, and capsules, Cordyceps has become increasingly popular in modern wellness routines. 

In this guide, we explore what these mushrooms are, the most well-researched Cordyceps benefits and the best ways to take them. It’s important to remember that the results of taking this mushroom may vary between individuals. While research is ongoing, we dive into both the evidence-based and emerging health benefits of Cordyceps.

What is Cordyceps?

Cordyceps mushrooms have a long history in traditional Chinese medicine. They have been used for centuries for benefits such as boosting energy levels, improving athletic performance, and supporting the immune system. Despite some misconceptions, Cordyceps is not native to the UK, but actually originates from the Tibetan Plateau and Himalayan regions. In the wild, Cordyceps is a parasitic fungus that grows on insects, most famously caterpillars, which is why it’s often called the ‘caterpillar mushroom’ – it’s worth noting that this process occurs only in nature, and poses no risk to humans.

Today, Cordyceps is cultivated using ethical and sustainable methods that preserve its beneficial compounds. There are many species, but the two most well-known are Cordyceps sinensis and Cordyceps militaris, with Cordyceps sinensis being the type we use for our Cordyceps Mushroom Tincture.

What are the key differences between Cordyceps Sinensis and Cordyceps Militaris?

Both Cordyceps sinensis and Cordyceps militaris offer a range of shared physical advantages. Many of the traditionally recognised benefits of Cordyceps sinensis and militaris relate to energy, stamina, respiratory support, and long-term vitality, which is why they have been valued in Chinese medicine for centuries. 

To help distinguish between the two, we’ve compiled the key differences:

How does Cordyceps work?

Cordyceps contains natural compounds that help support the body’s energy, oxygen use, and immune system. One of the mushroom’s key compounds is cordycepin, which is linked to energy and overall cell health. Another is adenosine, which helps the body deliver oxygen and use energy more efficiently, especially during exercise or stress. Cordyceps also contains polysaccharides, which help support immune function and protect cells from stress.

Together, these compounds help the body produce energy (ATP), reduce fatigue, and support balanced immune responses. Cordyceps is considered an adaptogen, meaning it may help the body better cope with physical, mental, and environmental stress while maintaining balance. Adaptogens are also said to have anti-ageing properties.

What is Cordyceps Good For?

Traditionally used in Chinese medicine and increasingly explored by modern science, Cordyceps may provide benefits ranging from energy and vitality to healthy ageing and antioxidant support. 

When considering taking Cordyceps, it’s important to note that – while findings are promising – much of the current evidence comes from animal studies or small human trials. Larger, well-designed human studies are still needed to fully confirm the effects, and results may vary between individuals.

1. Energy & Stamina Boost

• Supports ATP production and fatigue reduction: Studies suggest Cordyceps may help increase the body’s natural production of ATP, (the process cells use to create energy). By supporting cellular energy metabolism, this mushroom may help users feel less tired, maintaining energy levels throughout the day. A 1995 animal study by Manabe, N., et al. from Kyoto University suggests that Cordyceps sinensis extract may support cellular energy metabolism by increasing markers associated with ATP availability. 
• Alleviates chronic fatigue and supports active lifestyles: Cordyceps is commonly used by those with busy, physically demanding lifestyles or people experiencing ongoing low levels of energy, as it may help support endurance, stamina, and overall vitality. 

Our Cordyceps mushroom tinctures are made using a dual-extraction method, designed to capture both water- and alcohol-soluble compounds. This approach helps improve bioavailability, allowing a broader range of naturally occurring compounds to be present in the final extract. Learn more about why dual extraction is considered the gold standard in our detailed guide.

2. Respiratory Support, Athletic Performance & Recovery

• Improves oxygen efficiency and lung health: Cordyceps has traditionally been used to support respiratory health, including asthma and breathing difficulties. Research suggests it may help the body use oxygen more efficiently and may support healthy lung function during physical activity. 
• Increases endurance and athletic performance: Some studies indicate that taking Cordyceps may be associated with improved endurance and exercise capacity, likely linked to more efficient oxygen use and energy production. Because of this, it’s often used as pre-workout support. A study carried out in India by Pasha et al. found that athletes supplementing with Cordyceps militaris showed better oxygen levels, improved running performance, and reduced fatigue.

3. Hormonal & Libido Support

• Influences testosterone levels: Early research suggests Cordyceps may support hormone-related processes, including those linked to testosterone production. Some animal and small human studies have observed positive changes in hormonal function, though more research is needed to confirm these effects in humans. For instance, a 2003 study by Hsu et al. found that Cordyceps sinensis increased testosterone production in mice, both in laboratory tests and in live animals.
• Increases libido and supports fertility: Cordyceps has long been valued as a tonic for sexual vitality, reproductive health, and overall vitality. It has historically been used to support libido, stamina, and fertility in both men and women. In a study by Chang et al., supplementation with Cordyceps militaris was found to improve sperm count, sperm motility, and testosterone levels in rats.
• Provides positive changes for both men and women: At a top level, Cordyceps is used by men for support with energy, libido, and reproductive health, and by women to support vitality, hormonal balance, and sexual wellbeing.

4. Immune System Regulation

• Beta-glucans may help modulate immune response: Cordyceps contains beta-glucans, naturally occurring polysaccharides known for their role in immune system regulation. Rather than overstimulating immunity, beta-glucans interact with immune cells to help support a balanced response, which is important for both everyday immune resilience and long-term immune health. In 2024, researchers from the University of Phayao in Thailand found that a Cordyceps militaris beverage safely increased immune cell activity and reduced inflammation in healthy men and women.
• Used in traditional immune tonic preparations: In traditional Chinese medicine, Cordyceps has been used as part of immune-supporting tonic formulas, particularly during periods of fatigue, stress, or seasonal change, to help strengthen immune balance.

Are the benefits of Cordyceps different for men vs women?

Cordyceps may offer benefits for both men and women, though research often examines these effects separately.

When looking at the benefits of Cordyceps on female health, research and traditional use point towards support for energy, hormonal balance, stress resilience, and libido across different life stages. The most discussed advantages of Cordyceps on male wellbeing include support for stamina, testosterone-related pathways, libido, cardiovascular performance, and post-exercise recovery.

While traditional use suggests broad support for vitality in both sexes, human studies comparing male and female responses are limited. However, to help differentiate, we’ve pulled together some of the hypothesised benefits for both men and women:

Does the Cordyceps mushroom cause side effects?

Research into the long-term safety of Cordyceps mushrooms is still limited, so it’s important to consider individual health circumstances before use. Available studies suggest that Cordyceps is generally well-tolerated when taken in the right amounts. However, as with many functional mushrooms, mild side effects have been reported in some cases, most commonly dry mouth, nausea, or digestive discomfort.

Because responses can vary between individuals, speak with a medical professional before adding Cordyceps to your routine, especially if you have an existing health condition or are taking medication.

Extra care should be taken for those who: 

• Have an autoimmune condition: Taking Cordyceps may activate the immune system, increasing symptoms of autoimmune diseases in those who have autoimmune conditions. 
• Take prescription medication: Cordyceps may interact with certain medications, particularly those affecting immunity or blood clotting.
• Have food allergies or sensitivities: Individuals with mushroom allergies should avoid taking Cordyceps. Those with other food allergies should be extremely careful. 
• Are pregnant or breastfeeding: There is limited safety data for use during pregnancy or breastfeeding, so use is generally not recommended without medical guidance.

As a general rule of thumb, ensure you consult a healthcare professional before you take Cordyceps mushrooms. 

How can you take Cordyceps?

Cordyceps mushroom supplements are available in several forms, making it easy to find an option that suits your lifestyle. Common formats include tinctures (often called drops), powders, capsules, and teas. Each has its place, but they differ in absorption, convenience, and consistency.

Tinctures are often thought of as the most effective option, as they offer faster absorption and allow for precise, adjustable dosing. High-quality tinctures are usually made using advanced extraction methods that help preserve the mushroom’s bioactive compounds. They’re also easy to take, as you simply add drops to water, tea, or take them directly.

Powders and capsules offer convenience and portability, while teas provide a more traditional preparation method, though these may deliver fewer active compounds depending on processing.

Dosage and frequency can vary depending on the product, concentration, and individual needs. Always follow the guidance provided on the product label and start with a lower amount to assess tolerance. For more detailed guidance, visit our tincture guide.
