Cordyceps comes first for energy: in a human trial, three weeks of a blend containing Cordyceps militaris was associated with a longer time to exhaustion. Lion's Mane is second, for the tiredness that shows up as not thinking clearly. Both are hot water extracts from fruiting bodies, Cordyceps at 10:1 and Lion's Mane at 8:1. Neither contains caffeine, and both are taken in the morning, every day.
Start here. Cordyceps is the only mushroom we sell with a human trial measuring physical capacity rather than immunity or cognition.
Second, and the pick if what you call low energy is really not being able to think straight.

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 · 2017A double-blind trial in healthy young adults. A single dose produced faster performance on a processing-speed task, and after 28 days of daily use participants reported feeling less stressed. An encouraging early result, and the reason larger trials are now being called for.
Nutrients · 2023Forty-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.
Journal of Nutritional Science and Vitaminology · 2026A 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.
