What is cordyceps?

Cordyceps refers to a group of parasitic fungi with unusual life cycles. The species historically known as Cordyceps sinensis is now classified as Ophiocordyceps sinensis.

This fungus naturally infects caterpillar larvae in the high-altitude grasslands of the Tibetan Plateau. The fungus eventually replaces the host tissue, producing the distinctive fungus and caterpillar structure.

Traditional Chinese medicine refers to this structure as “winter worm, summer grass”. Wild Ophiocordyceps sinensis has historically been rare and highly valued. It is harvested by hand at high altitude and can command high prices.

Modern cultivation has made cordyceps products more widely available. Species such as Cordyceps militaris can be cultivated without a caterpillar host.

Cultivated cordyceps can provide compounds such as cordycepin and polysaccharides. However, the compounds and concentrations can vary between species and cultivation methods.

Energy, stamina, and exercise performance

Cordyceps has a long traditional history of use for supporting stamina and physical endurance. Modern research has explored its potential effects on energy production and exercise performance.

Some studies have investigated cordyceps and ATP production, the main energy currency used by your cells. Research has also explored whether cordyceps may influence oxygen utilisation during exercise.

Some trials have reported improvements in measures of exercise endurance and perceived fatigue. However, results have varied between studies and products.

Cordyceps remains popular among athletes and physically active people seeking natural support for their training. Its modern use builds on a traditional reputation for supporting stamina and physical performance.

Lung capacity and respiratory support

Cordyceps has a long history of traditional use in Chinese medicine for supporting healthy lung and respiratory function. Modern research has explored its potential effects on oxygen utilisation and respiratory performance.

These effects may help explain cordyceps’ traditional association with stamina and physical endurance. Efficient oxygen delivery is important for sustained physical activity and energy production.

Cordyceps has also been studied for potential adaptogenic properties. Research has explored whether it may help your body respond to physical and environmental stressors.

Its traditional use includes applications related to high-altitude environments. However, more research is needed to understand how cordyceps may affect your body’s response to altitude.

Immune support and practical use

Cordyceps contains polysaccharides, including beta glucans, which have attracted research interest for their potential effects on immune function.

Cultivated Cordyceps militaris is now widely used in cordyceps supplements. Products are available as capsules, powders and extracts, depending on the cultivation and processing method.

Powdered cordyceps can be added to hot drinks, smoothies and other foods. Extracts provide a more concentrated form of the mushroom’s naturally occurring compounds.

Cordyceps is generally well tolerated when used as directed. It is sometimes combined with adaptogenic herbs such as rhodiola or ashwagandha in products focused on energy and stamina.
