Cordyceps militaris is the mushroom for stamina. In a human trial, three weeks of daily use of a blend containing it was associated with a longer time to exhaustion and a higher ventilatory threshold. Ours is a 10:1 hot water extract from fruiting bodies, tested to at least 30% beta-glucans, and it goes in the morning. This page covers stamina and endurance, not heart health.

Cordyceps militaris
Start here. Cordyceps militaris is the only mushroom we sell with a human trial measuring how long people can keep working.
What customers report. Individual experience varies; none of this is a clinical claim.
Three weeks of daily supplementation was associated with a longer time to exhaustion, a higher ventilatory threshold and a higher VO2max; after one week, only time to exhaustion had improved. Read it for what it tested: the supplement was PeakO2, a six-species blend of mycelial biomass grown on oats, so nothing here is attributable to Cordyceps alone, and the three-week result comes from the 10 of 28 participants who continued that far. An encouraging early signal in a field that deserves a bigger trial.
Journal of Dietary Supplements · 2017Trained cyclists took Cs-4 for five weeks with no change to VO2peak or time-trial performance. Worth reading for the species: Cs-4 is Cordyceps sinensis, the wild caterpillar fungus, which is a different mushroom from the farmed Cordyceps militaris sold here and the one the positive exercise research was run on.
International Journal of Sport Nutrition and Exercise Metabolism · 2004A survey of the human research on Cordyceps militaris in exercise and recovery. It gathers the positive findings so far and calls for larger trials on consistently characterised preparations, which is the natural next step for an area attracting this much interest.
Nutrients · 2025Forty-seven healthy adults aged 60 and over ate bread containing 50 g of maitake daily for eighteen weeks. One strain produced a significant improvement on the Japanese Montreal Cognitive Assessment against placebo, and natural killer cell activity rose in the same group and tracked the cognitive score. Two strains were tested and one moved the needle, which tells researchers exactly where to look next.
