How it works

Human clinical trials show consistent improvements in ventilatory and metabolic thresholds, particularly in older adults and sedentary individuals. While some studies show VO2 max increases, results are mixed in highly trained athletes.

Cordycepin acts as an adenosine analog, potentially increasing ATP synthesis and improving oxygen utilization efficiency at the cellular level.

Safety

  • May have anti-platelet effects; use caution with blood-thinning medications.
  • May stimulate the immune system; avoid if you have an auto-immune condition.
  • Stop use 2 weeks before scheduled surgery.
