Prevention of Alcohol-Induced DNA Damage by a Proprietary Glycyrrhizin/D-Mannitol Product: A Randomized, Placebo-Controlled, Cross-over Human Study

The purpose of the present study was to evaluate the ability of a proprietary combination of glycyrrhizin and D-mannitol to protect against oxidative damage to DNA associated with acute alcohol consumption by human subjects in a randomized, placebo-controlled cross-over designed study. Excessive alcohol consumption is associated with numerous diseases. Alcohol has been shown to generate reactive oxygen species that can result in DNA damage, leading to genetic and epigenetic changes. Methods A total of 25 subjects (13 male and 12 female) were enrolled. Alcohol intake in the form of vodka (40 % ethanol) was adjusted based on 1.275 grams of 100 % ethanol/kg body weight for men and 1.020 grams/kg body weight for women which was consumed with and without the study product. Blood samples were drawn at two hours after alcohol consumption, lymphocytes were isolated, and subjected to DNA comet electrophoresis on a blinded basis. Results Acute alcohol consumption increased lymphocyte DNA damage by approximately 8.36 %. Co-consumption of the glycyrrhizin/D-mannitol study product with alcohol reduced DNA damage to baseline levels. No adverse effects were associated with use of the study product, and no differences were observed in blood alcohol concentrations in the presence or absence of the study product in males and females. Conclusions Acute alcohol ingestion resulted in measurable increases in DNA damage which were prevented by the addition of the proprietary glycyrrhizin/D-mannitol (NTX®) study product to the alcohol, suggesting that the tissue damaging effects of alcohol consumption can be ameliorated.
