Официальное название

Mood and Well-Being Following 12 Weeks of Daily Centrum Silver Multivitamin Supplementation in Adults Between 40-60: A Neurophysiological EEG Study Using the Cognalyzer EEG Analysis

Обзор

The goal of this clinical trial is to learn whether 12 weeks of use of Centrum® Silver Daily Multivitamin can improve mood, and overall well-being in older adults The main questions it aims to answer are: 1. Does daily use of the multivitamin over a 12 week period improve well-being indicators as measured using EEG-based and subjective mood tests? 2. Does perturbation in mood effects due to cognitive load after a battery of cognitive assessments improve after 12 weeks of multivitamin intake.

Подробное описание

This was a prospective, single-arm, observational study evaluating the effects of regular use of a Centrum multivitamin on mood, measured with subjective questionnaires and neurophysiological responses in adults between 40-60.

Participants were recruited from a large group who participated in a 5 day nutritional intake monitoring program (ASA24®, https://epi.grants.cancer.gov/asa24/). The participants with the lowest scores on the ASA evaluation were selected to participate in the study. All participants provided written informed consent before any study procedures.

The study consisted of two visits: a baseline visit (EEG, questionnaires), a period of 12 weeks of daily multivitamin use, followed by a second visit assessing extended effects of product use. Daily monitoring and weekly questionnaires continued throughout the product intake period.

EEG recordings were analyzed using Cognalyzer® EEG-based metrics, including mood valence, relaxation, and mental arousal. The primary objective was to evaluate changes in neurophysiological and self-reported measures of stress and relaxation both before and after a battery of cognitive assessments; exploratory objectives included a variety of other well-being measures measured both using EEG and standardized psychometric tests.
