Cordyceps’ lead bioactives—cordycepin (3′-deoxyadenosine) and adenosine—signal through AMPK and adenosine pathways to upscale mitochondrial output, translating oxygen into ATP more efficiently.

It down-regulates inflammatory noise (e.g., NF-κB) and nudges nitric-oxide/calcium dynamics, smoothing cardio-respiratory throughput and recovery.

Cleaner, steadier energy and perceived endurance—fewer spike-and-crash moments (unlike caffeine), depending on dose, consistency, and baseline fitness. (start with 1 gram a day and work your way up over a month)
