Summary

Study Design Type: Randomized, blinded, placebo-controlled, crossover trial Participants: 40 volunteers, divided into two groups (n=20) Grouping Method: Minimization randomization based on age and BMI matching Intervention Sequence: Group A: Probiotic intervention → washout → placebo intervention Group B: Placebo intervention → washout → probiotic intervention Blinding: Participants, data collectors, and data analysts were blinded Roles: Randomization, data collection, and data analysis were performed by different researchers Intervention Process Phase 1 (Week 1): Group A: Took probiotic tablets (1g twice daily, 0.5g/tablet) Group B: Took placebo tablets (1g twice daily, 0.5g/tablet) Washout Period: 2 weeks Phase 2 (Week 4): Group A: Took placebo tablets Group B: Took probiotic tablets Sample Collection Fecal Samples: Collected at three time points: Baseline (1 week before alcohol test) Day 7 (after Phase 1) Day 28 (after Phase 2) Alcohol Tests: Conducted on Day 7 and Day 28 after overnight fasting Body Weight: Measured on test days; alcohol dosage adjusted accordingly (1 mL/kg, 40% v/v) Serum and Saliva: Collected at multiple time points post-alcohol consumption

Detailed description

A randomized, blinded, placebo-controlled, crossover trial was conducted. Forty participants were divided into two groups (n=20). Then, for each block, randomization was performed by minimization by matching age and body mass index (BMI). The two groups received different sequences of Probiotic combination intervention and maltodextrin intervention (placebo), coded as A and B to conceal their identities. Participants, data collectors, and data analysts were blinded throughout the study. Different researchers performed randomization, data collection, and data analysis. The 40 volunteers recruited were randomly divided into two groups (n=20) after signing the informed consent form, namely the Probiotic combination intervention group (Group A, probiotic intake → flushing → placebo intake) and the maltodextrin (placebo) group (Group B, placebo intake → flushing → probiotic intake). Group A tried the compressed tablet product for 1 week, and Group B tried the placebo for 1 week; after a 2-week washout period, Group A tried the placebo for 1 week, and Group B tried the compressed tablet product for 1 week. During the intervention period, volunteers took 1g of the compressed tablets twice a day (0.5g/tablet, 2 tablets) in the morning, noon and evening, and during the intervention period, volunteers took 1g of the placebo twice a day (0.5g/tablet, 2 tablets) in the morning and evening. Feces of all volunteers were collected one week before the alcohol experiment (first time), and the second and third feces were collected on the 7th and 28th days, respectively. Alcohol tests were performed on the 7th and 28th days after an overnight fast. Body weight was measured on the test day, and liquor was provided according to body weight. Participants ate a meal (standard diet) containing alcohol (alcohol content: 40% v/v, 1 mL/kg body weight), and serum and saliva of volunteers were collected at different time points after the meal. During the intervention period, all subjects followed their original dietary habits and stopped taking other alcohol-detoxifying and liver-protecting drugs or drugs that may affect alcohol metabolism. The medication method during the alcohol test was: 2 pills before the alcohol tolerance test after lunch (the first time point); 2 pills before drinking (i.e., before the hangover test at two time points); and 2 pills after waking up.

COMBINATION_PRODUCT	Probiotic tablet candy group	40 volunteers were randomly divided into two groups (n=20): Group A (probiotic → washout → placebo) and Group B (placebo → washout → probiotic). Each group took 1g of tablets (0.5g/tablet, 2 tablets) twice daily for 1 week, followed by a 2-week washout, then switched interventions. Fecal samples were collected at baseline, Day 7, and Day 28. Alcohol tests were conducted on Days 7 and 28 after fasting; participants consumed alcohol (1 mL/kg, 40% v/v) with a standard meal. Serum and saliva were collected post-meal. Body weight was measured, and alcohol dosage was adjusted accordingly. Participants maintained their usual diet and avoided alcohol-detoxifying or liver-protecting drugs. Medication during alcohol tests: 2 pills before tolerance test (after lunch), 2 pills before drinking, and 2 pills after waking.
