Abstract

This open-labeled and comparative study aimed to test the efficacy and safety of a fermented rice extract-based substance containing yeast-fermented powder having aldehyde dehydrogenase (KisLip®, Pico Entech, Republic of Korea) in healthy male individuals. Healthy male subjects (n = 20) consumed 90 g of alcohol at their first visit. At the second visit, participants consumed 90 g of alcohol or alcohol with a low dose of KISLip® (2000 mg, KL-L) and then 90 g of alcohol or alcohol with a high dose of KISLip® (3000 mg, KL-H) at the third visit. The efficacy of KISLip® depends on the mutational status of important genes related to alcohol metabolism, including alcohol dehydrogenase (ADH1B), cytochrome P4502E1 (CYP2E1 (5B) and CYP2E1 (6)), and aldehyde dehydrogenase (ALDH2). KISLip® significantly reduced the highest level (Cmax) of alcohol and overall levels of acetaldehyde compared to the alcohol-only group in a dose-dependent manner. These significant effects of KISLip® on alcohol metabolism were observed independent of mutations in the four genes. In addition, hangover symptoms were significantly decreased in the KISLip® treated groups. During the study, the participants did not show any adverse events after KISLip® intake. This clinical study suggested that supplementation of KISLip® had beneficial effects on alcohol metabolism and might ameliorate the severity of hangovers without any adverse events.
