NCT03935841

Brief Summary

An open-labeled intervention study testing healthy, lean, and male volunteers on two separate occasions:

  1. 1.blood sampling after consuming 36 gram 3-Hydroxybutyrate (3-OHB) salt.
  2. 2.blood sampling while given a variable rate of 3-OHB salt intravenously to replicate the concentrations seen during oral consumption.
