Supplements such as magnesium, lion’s mane, creatine and collagen are being marketed as must-haves for perimenopause and menopause. But how much of this is actually grounded in science?

During perimenopause and menopause, fluctuating and declining oestrogen levels can trigger symptoms such as hot flushes, night sweats, sleep disruption, anxiety, brain fog, joint pain and changes in muscle mass and body composition.

Hormone replacement therapy (HRT) remains the most effective treatment for many symptoms, but not everyone can or wants to use it. This is why alternative remedies attract so much attention.

Magnesium plays a role in more than 300 metabolic processes, including muscle relaxation, nerve signalling and blood pressure regulation. Several menopause-related symptoms overlap with areas where magnesium has effects.

For instance, many menopausal women experience sleep problems. Clinical trials in adults, including older women, show magnesium can improve how fast you fall asleep and reduce insomnia severity.

Anxiety can also be an issue for menopausal women. Meta analyses show magnesium supplements can modestly reduce anxiety symptoms – particularly in people with low magnesium levels. However, this research wasn’t specifically done in menopausal women.

Menopause also places women at higher risk of osteoporosis (weakened bones). As oestrogen levels fall during menopause, certain bone cells become more active, causing bone to be lost faster than it’s rebuilt.

But magnesium contributes to bone density by encouraging the formation of new........
