Cordyceps and Reishi have carried a reputation for vitality for centuries, and each covers half the day. Cordyceps is the daytime half: in a human trial, three weeks of a blend containing it was associated with a longer time to exhaustion. Reishi is the evening half and the most studied mushroom we sell, with 17 clinical trials pooled in a 2025 review. Both are 10:1 hot water extracts, tested to at least 30% beta-glucans.
Start here, but buy it for the energy research rather than the reputation. Cordyceps is the mushroom with a human trial; it is not a trial about libido.
Second, and the more useful of the two for most people who land here. Being tired and badly slept affects a great deal, and Reishi is the extract for that end of the day.

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 · 2017The widest survey of the Reishi literature: 17 clinical trials covering 971 participants, at doses from 200 to 11,200 mg a day. Pooled analysis found significant improvements in BMI, serum creatinine, glutathione peroxidase and resting heart rate. Many other markers did not move, and the reviewers rate the certainty of the underlying trials as low and call for better-designed studies, which is the usual state of a field this active and this young.
Food Science & Nutrition · 2025A 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.
