Ketone Esters for Optimization of Operator Performance in Hypoxia

The primary purpose of the study was to investigate effects of an orally administered ketone ester drink on endurance exercise performance during acute extreme hypoxia. Drinking this ketone supplement increases energy substrates known as ketone bodies in the blood, which may also act as metabolic signaling molecules. The ketone drink used in this study is recognized by the FDA as generally regarded as safe (GRAS). Some reports suggest that high ketone levels may enhance one's ability to tolerate hypoxia.
