Key finding
Two weeks of D-BHB before bed improved self-rated sleep quality versus placebo.
What the study did
90 healthy Japanese adults with poor sleep scores took placebo, 1.5 g, or 2.9 g D-BHB one hour before bed for 14 days. Both D-BHB doses improved sleepiness on rising and other sleep quality scores versus placebo, including sleep initiation and feeling refreshed. No adverse events were reported.
This study used [form], not goBHB. It is shown here as general ketone science. Only goBHB studies back goBHB product claims.
