Brief Summary

Perimenopause is a transition phase into menopause, characterised by menopausal symptoms while menstrual periods are still occurring. Common symptoms of perimenopause include hot flushes, night sweats, mood swings, anxiety, sleep disturbances, fatigue, and cognitive difficulties. These symptoms can be both frequent and intense, with the potential to significantly deteriorate women's quality of life. Despite an increase in public discourse around menopause, there are still large gaps in knowledge. Previous literature has suggested a relationship between diet and menopause management. However, studies in this area are limited and women often rely on social media for advice on supplements to address menopause complaints. One supplement that has received a lot of attention with purported benefits for menopause is magnesium, primarily due to its links to energy and or/sleep, however no studies have explored psychological effects of magnesium supplementation in perimenopause. The aim of this study is to explore the effects of 12-weeks magnesium supplementation on perimenopause symptoms, cognition, sleep, and psychological well-being.

Outcome Measures

Primary Outcomes (11)

  • Numeric working memory task % accuracy

    Cognitive function - working memory task. Measured as a percentage, with a higher score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • Numeric working memory task reaction time

    Cognitive function - working memory task. Measured as reaction time (in milliseconds), with a lower score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • 3-back task % accuracy

    Cognitive function - working memory task. Measured as a percentage, with a higher score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • 3-Back task reaction time

    Cognitive function - working memory task. Measured as reaction time (in milliseconds), with a lower score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • Corsi blocks task score

    Cognitive function - working memory task. Scored as level of difficulty reached (4 upwards), with a higher score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • Alphabetic working memory task % accuracy

    Cognitive function - working memory task. Measured as a percentage, with a higher score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • Alphabetic working memory task reaction time

    Cognitive function - working memory task. Measured as reaction time (in milliseconds), with a lower score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • Word recognition % accuracy

    Cognitive function - episodic memory. Measured as a percentage, with a higher score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • Word recognition reaction time

    Cognitive function - episodic memory task. Measured as reaction time (in milliseconds), with a lower score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • Picture recognition % accuracy

    Cognitive function - episodic memory task. Measured as a percentage, with a higher score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

  • Picture recognition reaction time

    Cognitive function - episodic memory task. Measured as reaction time (in milliseconds), with a lower score indicating better performance.

    Conducted at baseline (pre-dose), at 6 weeks post-dose, and at 12 weeks post-dose.

Secondary Outcomes (7)

  • The Menopause-Specific Quality of Life Questionnaire (Hilditch, 1996)
