What was tested
Participants received 4 grams daily of a Cordyceps militaris-containing blend or maltodextrin placebo. Cycling tests assessed oxygen consumption, exhaustion time and power. Ten volunteers continued for two additional weeks. [1]
At one week, none of the reported treatment-by-time interactions was significant. The later phase reported improved maximal oxygen consumption, but its small volunteer sample makes the result particularly uncertain. [1]
How far the result applies
Within-group confidence intervals should not replace the randomized between-group comparison. The formulation also contained multiple mushrooms, so it cannot isolate the effect of Cordyceps. Funding and conflicts were not established from the retrieved abstract. A general energy or focus claim exceeds these exercise endpoints. [1]
A hypothetical reading of the evidence
Imagine only a minority continues a trial. A promising later result deserves attention to both its uncertainty and who remained.
| Detail | Interpretation |
|---|---|
| Study result | Limited to its measured outcomes |
| Other preparation | Equivalence not established |
| Broader claim | Needs separate evidence |
