The goal of this clinical trial is to learn the effects of ketone supplement compared to placebo on alcohol withdrawal symptoms during a 4 day alcohol withdrawal management treatment in adults with moderate to severe alcohol use disorder at the Hospital of the University of Pennsylvania, Cedar Detox Center.

This is a 4-day randomized double-blinded intervention study of 30 treatment seeking adults with alcohol use disorder, who are receiving alcohol detoxification treatment at the Hospital of the University of Pennsylvania, Cedar Detox Center. Within 24 hours of admission to the inpatient unit, participants will be consented and randomized to receive 3x daily of 12g of KS (n=15; 1,3-butanediol and D-hydroxybutyric acid from Kenetik, VitaNav Inc., Washington D.C.) for 4 days or placebo beverage (n=15). Benzodiazepines and other "comfort" medications will be administered daily following the HUP Cedar withdrawal management protocol, with benzodiazepines administered based on withdrawal symptoms, monitored with the revised Clinical Institute Withdrawal Assessment for Alcohol. The revised Clinical Institute Withdrawal Assessment for Alcohol is given three or more times a day clinically to determine patient withdrawal levels and adjust medication dosages. Total daily maximum revised Clinical Institute Withdrawal Assessment for Alcohol scores, benzodiazepine dosage, and other "comfort" medications will be analyzed with a repeated measures design, with a binary factor for intervention, factor of time, and intervention by time interaction. Daily mood questions and alcohol craving questions will assess differences between treatment groups. After 4 days of study intervention, all participants will undergo an approximately 1.5-hr. magnetic resonance imaging session.
