2.2.1. Recruitments Strategies
RECRUITMENT
Participants were recruited in Santiago de Chile through an open call on social media (i.e., Instagram) from January 2021 to February 2021. Social media-based recruitment strategies were used to invite participants with video posts explaining the experiment and main outcomes (brain-gut-microbiota axis health and well-being). Interested people fulfilled an anonymous self-report survey giving the information necessary to assess the inclusion/exclusion criteria. Selected candidates received an email with the online version of the informed consent and general information about the intervention, sampling, and timelines. Interested candidates confirmed their participation via email and signed the informed consent prior to initiation of the experimental procedures.
