NCT06126094

Brief Summary

Myrkl is advertised as a dietary supplement for use before alcohol consumption that is effective in prevention of side effects during the next day. With this research, the investigators want to determine the impact of the mentioned dietary supplement on the intestinal microbiome. For this purpose, the research was designed in three phases before, during and after the research as a double blind trial. In doing so, the subjects take a stool sample before and after the intervention and during the intervention, fill out questionnaires and undergo cognitive tests. At the same time, they give a blood sample after the intervention. After the results of the analysis are due, the researchers enter the data into the for that the predicted Access table (rel. representation of genera/genera/species, average results by questionnaires). The entered data is processed as part of statistical analysis.

Outcome Measures

Primary Outcomes (1)

  • Gut microbiome composition

    The impact of Myrkl on gut microbiome shall assessed through monitoring of relative taxonomic abundance of bacteria that compose gut microbiota from samples taken day before the intervention and after the intervention. The composition of the intestinal microbiota will be determined by sequencing the 16s rRNA bacteria in the stool sample. Subjects take a sample with a sterile cotton swab by wiping stool with toilet paper in their home on a given day research. The sample is stored in a tube with a buffer liquid so that the sample can be stored and transported at room temperature temperature. The test sample is transported by air to the laboratory of Biomes NGS Gesellschaft mit beschränkter Haftung, Wildau, Germany.

Study Arms (2)

Probiotic

EXPERIMENTAL

Participants will consume 800 mg of probiotic Myrkl before consuming alcohol in the form of one capsule. (Myrkl, De Fair Medical, Stockholm, Sweden). This formulation contains AB001™, and one capsule (800mg) consists of: * 560 mg of naturally fermented rice bran * Bacillus subtilis * B. coagulans * L-cysteine * dextrin * 36 mg of excipients: magnesium stearate salts, calcium phosphate, potassium phosphate

Dietary Supplement: Myrkl

Placebo

EXPERIMENTAL

The subject who consumed 800 mg of placebo- dextrin (maltodextrin) in the form of two capsules before consuming alcohol.

Dietary Supplement: dextrin
