Overview

Cordyceps is a genus of medicinal mushrooms that has been used in traditional Chinese medicine for centuries. The most studied species is Cordyceps militaris, which is now cultivated commercially (wild Cordyceps sinensis is extremely rare and expensive).

Cordyceps is valued for its potential to support energy production, athletic performance, respiratory health, and immune function. It contains unique compounds like cordycepin and adenosine that may influence cellular energy (ATP) production.

Potential Benefits

Energy & ATP Production

May support cellular energy production by increasing ATP levels. Popular among athletes for endurance and recovery.

Athletic Performance

Some studies show improvements in VO2 max, time to exhaustion, and exercise recovery. Popular with endurance athletes.

Respiratory Support

Traditionally used for respiratory health. May support lung function and oxygen utilization.

Generally Well Tolerated

Cordyceps is very safe at recommended doses. Most people tolerate it well with minimal side effects.

Research Snapshot

Cordyceps has been studied for its effects on exercise performance, respiratory function, and immune health. A 2017 randomized controlled trial found that a Cordyceps militaris supplement significantly improved VO2 max and time to exhaustion after three weeks of supplementation.
