Efficacy of the Dietary Food Supplement ALCOFILTRUM in Alleviating Alcohol Hangover Symptoms

The aim of this open-label, randomized, crossover, comparative pilot study is to assess efficacy and safety of the dietary food supplement ALCOFILTRUM in healthy volunteers who consume alcohol. Specifically the study will evaluate:

* Efficacy of the intervention to alleviate hangover symptoms in participants who consumed alcohol,
* Safety of intervention in participants who consuming alcohol.

Participants will take four tablets of ALCOFILTRUM dietary food supplement 30 minutes before alcohol ingestion, while the control group will intake only alcohol drink.

Heavy drinking of alcoholic beverages may lead to hangover, characterized by a combination of unpleasant physical and mental symptoms that affect mood, cognition, and physical functioning. Hangover symptoms begin within several hours following drinking cessation, when a person's blood alcohol concentration (BAC) is falling, and peak when BAC is zero. The symptoms may continue for up to 24 hours thereafter. Multiple contributing factors are responsible for the development of alcohol hangover symptoms which include ethanol itself, its metabolites and congeners / fusel alcohols. The liver plays a key role in alcohol detoxification, and is therefore affected the most. Drinking large amounts of alcohol can lead to significant damage to the liver and brain cells, the reason for the need for protection.

In this open-label, randomized, cross-over, comparative pilot study investigators aim to assess efficacy and safety of the dietary food supplement ALCOFILTRUM in healthy volunteers who consume alcohol. Participants will consume an alcoholic drink (Bulbash Nano Original vodka 40%) in a dose calculated for every study subject based on ethanol 1.7g/kg body weight. The test group will take 4 tablets of ALCOFILTRUM dietary food supplement, 30 minutes before alcohol ingestion, while the control group will intake only alcohol drink. Twelve to thirteen hours after the last alcohol intake hangover symptoms will be evaluated based on questionnaires, and measurements of balance / coordination, attention and blood parameters. The findings from this study will provide important insight of a possible intervention for alleviating alcohol hangover symptoms.
