Key finding
A single dose of BHB improved reaction speed (L-BHB) and cut attention lapses versus placebo in healthy adults.
What the study did
136 healthy fasted adults were randomized to D-BHB, L-BHB, or placebo. Vigilance was tested at baseline and 60 minutes post-drink with the Psychomotor Vigilance Test and a CNS tap test. The L-BHB group reacted significantly faster than placebo. Both BHB groups had fewer attention lapses than placebo across all time points.
This study used [form], not goBHB. It is shown here as general ketone science. Only goBHB studies back goBHB product claims.
