Magnesium
Magnesium shows solid evidence for improving sleep quality and reducing muscle cramps, two frequent menopause companions. Hot flash relief has weaker evidence, but magnesium's excellent safety profile and role in bone health make it a reasonable addition to most women's routines. Since most of us fall short of recommended intake through food alone, gentle supplementation alongside magnesium-rich foods offers a practical path forward.

Overall: Mixed evidence
Randomised controlled trials
Several small randomized trials show benefits for sleep quality and muscle cramps, but hot flash studies have produced inconsistent results.
Large population studies consistently link adequate magnesium intake with better sleep patterns and bone density in midlife women.
Meta-analyses support magnesium for sleep quality and muscle function, but conclude evidence for menopausal hot flashes remains insufficient.
Menopause-specific trials
Few studies have focused specifically on perimenopausal and menopausal women, with most including mixed populations or postmenopausal women only.
What we do not know
Most magnesium studies for menopause symptoms included only small groups of women (under 100 participants). We don't know the optimal dose specifically for perimenopausal women experiencing sleep disruption. Long-term safety data beyond 12 months of supplementation is limited. The comparison between different forms of magnesium (glycinate vs. oxide vs. citrate) for menopause symptoms hasn't been directly studied. We also lack evidence on how magnesium interacts with hormone therapy in this population.
How it is used
Common dose range
200-400mg daily
Notes on dosing
Best taken at night. Glycinate and citrate absorb better than oxide.
Get it from food first
Food sources are better absorbed than most supplements and come with co-factors that support the same pathways. If you eat two or three of these consistently, you may not need a supplement at all.
pumpkin seeds
156 mg per ounce
also provide zinc and healthy fats
dark chocolate (70-85%)
64 mg per ounce
choose quality brands with minimal processing
almonds
80 mg per ounce
also support heart health
spinach
157 mg per cup cooked
better absorbed when cooked
black beans
120 mg per cup
also provide fiber and protein
avocado
58 mg per medium fruit
supports hormone production
Mediterranean diet
Emphasizes magnesium-rich nuts, seeds, leafy greens, and whole grains while limiting processed foods that deplete magnesium
Anti-inflammatory eating
Focuses on whole foods naturally high in magnesium while reducing sugar and refined foods that increase magnesium needs
What depletes Magnesium
High sugar intake, excessive alcohol consumption, chronic stress, certain medications (diuretics, proton pump inhibitors), and highly processed foods that are stripped of magnesium during manufacturing. Coffee and tea can also slightly reduce absorption when consumed with magnesium-rich meals.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"Magnesium is one of those gentle allies that supports your body's basic functions while you navigate this transition. The evidence for sleep and muscle comfort is encouraging, and since most of us need more anyway, it's a reasonable place to start. Focus on magnesium-rich foods first, then consider a modest supplement if you're still falling short."
