Registration Number
NCT06154616
Lead Sponsor
Universidad Católica San Antonio de Murcia
Brief Summary

Randomized, controlled, double-blind intervention study, with four parallel branches depending on the product consumed, to analyze the efficacy of different types of milks on the improvement of sleep quality.

Detailed Description

The duration of the study will be 90 days (12 weeks). Each day they will have to consume the product under investigation. The subjects who meet the selection criteria will be randomly distributed in each of the study groups (A, B, C or D, depending on the group in which they have been randomized). Each day the subjects will have to fill in a diary on sleep quality and concomitant medication.

They will make a total of two visits to the research laboratory and the tests preestablished in the protocol will be performed. Subsequently, a statistical analysis will be performed with the variables measured in the study to obtain the results.
