Organic Cordyceps and Oxygen Utilization

By Purelung Research Team · Reviewed by Dr. Jonathan Reeves, M.D. · Updated June 2026

Organic Cordyceps is one of the most studied traditional ingredients for endurance and oxygen utilization — and a standout ingredient in Purelung. Here's why it matters.

What Is Cordyceps?

Cordyceps is a traditional fungus studied for its role in supporting quality of life measures related to respiratory performance, including in research on moderate-to-severe asthma (Hindawi).

Supports Oxygen Utilization

Cordyceps is traditionally used to support how efficiently the body uses oxygen, particularly during physical activity.

Supports Endurance

Alongside its oxygen-utilization role, Cordyceps carries a long traditional-use history for supporting stamina and endurance.

Cordyceps in Purelung

Purelung includes Organic Cordyceps as its featured endurance-support ingredient — see the ingredients page and the current Purelung discount on the Purelung official website.

Cordyceps supports oxygen utilization and is not a treatment for asthma or any respiratory disease. Consult your doctor before use if you have a respiratory condition or take medication.
