Influences of Multivitamin Supplementation on Health Parameters

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03071796
Recruitment Status : Completed
First Posted : March 7, 2017
Last Update Posted : June 23, 2017

Kuno Hottenrott, Prof., Martin-Luther-Universität Halle-Wittenberg

Brief Summary:
In this study the investigator will evaluate whether a liquid multivitamin supplement influences blood and vital parameters. Furthermore the investigator will establish the effects on life quality, mood and perception of stress and will characterize changes on immune system.

Condition or disease Intervention/treatment Phase
Health Behavior Dietary Supplement: multivitamin supplement Dietary Supplement: Placebo Not Applicable

Detailed Description:

The double-blind, randomized intervention study is conducted for 12 weeks and includes two groups (placebo versus verum) with same number of participants.

The investigator aims to determine the effects of multivitamin supplement on blood and vital parameters which includes blood pressure, pulse, heart rate, variability of heart rate, vitamin D, vitamin B12, folic acid, homocysteine, HbA1c. Furthermore the investigator will access life quality, mood and perception of stress through the following questionnaire POMS, PSS-10, SF12 & SF36. The investigator will evaluate whether the multivitamin supplement changes the frequency of diseases like cold which represents the function of the immune system.
