Abstract

Background: Despite some evidence of the helpful role of ketones in some neuropsychiatrie disorders, there are no clinical trials that examine these agents for posttraumatic stress disorder (PTSD). Our aim was to investigate whether ketone salt supplementation can improve PTSD symptoms in a randomized, placebo-controlled trial. methods: A total of 21 participants were recruited and randomized to placebo or ketone supplement. Each dose of ketone supplement included 7 g of ketones in the form of beta-hydroxybutyrate for a total of 14 g/d. Data were collected through questionnaires to assess PTSD symptoms. We used Fisher's exact tests for categorical variables and 2-sample t tests for continuous variables to examine differences in baseline values between treatment groups. Mixed models were employed to examine changes over time between groups on the PTSD Checklist for DSM-5 (PCL-5). results: There were no statistically significant differences in PCL-5 medians between the ketone and control groups at pretest (P = 1.0000) or post-test (P =.6020). The ketone group had a statistically significant decrease in median PCL-5 scores from 58.5 (pretest) to 54.0 (posttest; P =.0003) but the control group did not change (34 at pretest and at posttest; P =.4418). Conclusions: The ketone group showed a significant decrease in PCL-5 score at posttest compared with pretest that was not seen in the control group, although these changes were not statistically significant between groups. The small sample size limited the study and likely contributed to the lack of significance. Larger trials are needed to more definitively examine these findings.
