OmniSolutions Laboratory Holdings Limited12 enrolled

Overview

This was a single-center, open-label, exploratory crossover study evaluating acute hangover symptoms after use of NatureU Cheers Friends Curcumin compared with an active comparator product in healthy adult men. Participants completed two independent test-food sessions separated by at least 48 hours. Sixteen participants were recruited, 12 were screened and enrolled, and 12 were included in the effectiveness analysis. In the control session, participants took Herbsense hangover relief tablets 30 minutes before alcohol intake. In the NatureU Cheers Friends Curcumin session, participants took NatureU Cheers Friends Curcumin 30 minutes before alcohol intake. The main outcome was the Acute Hangover Scale (AHS) assessed the morning after each test session. Safety was monitored during the test procedures.

The study was designed as an exploratory human evaluation of a functional food product intended to support post-alcohol hangover relief. Eligible healthy adult male participants completed two independent test-food sessions under researcher supervision. Screening was performed on June 19, 2024, eligible participants were enrolled on June 20, 2024, and the final next-morning questionnaire assessment was completed on June 21, 2024. Participants were instructed not to drink alcohol for 24 hours before each test day and not to eat during the 3 hours before testing. On each test day, participants arrived at the study center at approximately 18:00, completed check-in and baseline assessments including blood pressure, pulse rate, and breath alcohol measurement, and received the assigned test product at approximately 18:30. At approximately 19:00, participants consumed 100 mL of commercially available 52% Chinese baijiu within 10-15 minutes and consumed a standardized meal within 30 minutes. Blood pressure and pulse rate were measured 30, 60, and 120 minutes after alcohol intake. Participants completed the Acute Hangover Scale the next morning after waking. The study was open-label and exploratory, with no masking. Analyses compared AHS scores after NatureU Cheers Friends Curcumin with scores after the comparator product.
