    General information about the trial
    Main objective of the trial
    To demonstrate the superiority of Magne B6® (Magnesium [Mg] + vitamin B6) versus Magnespasmyl® (Mg only) supplementation on stress level, evaluated by the stress subscale from the Depression Anxiety Stress Scale (DASS)-42 test, in chronically stressed subjects, with suboptimal serum Mg levels.
    Protection of trial subjects
    Subjects were fully informed of all pertinent aspects of the clinical trial as well as the possibility to discontinue at any time in language and terms appropriate for the subject and considering the local culture. During the course of the trial, subjects were provided with individual subject cards indicating the nature of the trial the subject is participating, contact details and any information needed in the event of a medical emergency. Collected personal data and human biological samples were processed in compliance with the Sanofi-Aventis Group Personal Data Protection Charter ensuring that the Group abides by the laws governing personal data protection in force in all countries in which it operates.

    Recruitment
    Recruitment details
    The study was conducted at 4 centres in France. A total of 854 subjects were screened between 04 May 2016 and 25 January 2017 of whom 586 were screen failures. Screen failures were mainly due to exclusion criteria met.

    Pre-assignment
    Screening details
    A total of 268 subjects were randomized in the study. Of which, 264 subjects were treated in 1:1 ratio to the MagneB6® and Magnespasmyl® arms. The randomization was stratified by sex on a 1:1 ratio.

    Change From Baseline in DASS-42 Stress Subscale at Week 8: Modified Intent to Treat (mITT) Population
    End point description
    DASS-42 is a 42-item questionnaire consisting of 3 sub-scales (depression, anxiety and stress) to measure the negative emotional states of depression, anxiety and stress. Each sub-scale contains 14 items. The stress sub-scale items were scored on a 4-point rating scale: 0 (Did not apply to me at all) to 3 (Applies to me most of the time). The sub-scale score ranges from 0 to 42, where cut-off score from 0-14= normal, 15-18= mild, 19-25= moderate, 26-33= severe and 34-42= extremely severe stress level. Analysis was performed on mITT population which included all subjects randomized in the study with at least one consumption of study product (MagneB6® or Magnespasmyl®) and an evaluable DASS-42 stress score at baseline and at least one during the treatment period.

    Change From Baseline in Anxiety Subscore at Week 4 and 8
    End point description
    DASS-42 is a 42-item questionnaire consisting of 3 sub-scales (depression, anxiety and stress) to measure the negative emotional states of depression, anxiety and stress. Each sub-scale contains 14 items. The anxiety sub-scale items were scored on a 4-point rating scale: 0 (Did not apply to me at all) to 3 (Applies to me most of the time). The sub-scale score ranges from 0 to 42, where cut-off score from 0-7= normal, 8-9= mild, 10-14= moderate, 15-19= severe and 20-42= extremely severe anxiety level. Analysis was performed on mITT population.

    Change from Baseline in Cortisol Awakening Response (CAR) at Week 4 and 8
    End point description
    CAR is an allostatic indicator used as a biomarker to quantify stress levels. This test was done by subjects at home on 2 days (the day before visit & day of visit [except for baseline visit)]). Three saliva samples were collected by day: 0, 30 & 45 minutes after awakening & before breakfast on Day 2 and 3 (for baseline), Day 27 and 28 (for Week 4) and Day 55 and 56 (for Week 8). CAR kits were dispensed to subjects for saliva cortisol sampling. Change from baseline at Week 4 and Week 8 was measured by the mean over 2 days of total area under the curve (AUCt) (0, 30 and 45 minutes) of CAR. Difference in adjusted mean was analysed from ANCOVA, adjusted on sex. Analysis was performed on mITT population.
