Magnesium for Women:
PMS, Menopause & Everyday Wellness

Magnesium is an essential mineral that supports women throughout every stage of life. From the menstrual years through pregnancy, perimenopause, menopause and beyond, maintaining an adequate magnesium intake is an important part of good nutrition.

Magnesium contributes to normal muscle and nervous system function, energy metabolism, electrolyte balance and the maintenance of healthy bones.

Here’s what women should know about magnesium and how its importance can change throughout life.

Why Is Magnesium Important for Women?

Women need magnesium every day to support a wide range of normal functions throughout the body.

Magnesium contributes to:

Normal muscle function
Normal nervous system function
Normal energy metabolism
Electrolyte balance
Normal protein synthesis
Maintenance of healthy bones

While these functions aren't unique to women, magnesium becomes particularly interesting when we look at menstrual health, pregnancy, physical activity, menopause and healthy ageing.

Magnesium & Periods

Magnesium is often discussed in relation to periods, menstrual cramps and PMS because of its involvement in normal muscle and nervous system function.

Although magnesium shouldn't be considered a treatment for period symptoms, maintaining adequate magnesium intake throughout the menstrual cycle is an important part of good nutrition.

Magnesium & Period Cramps

Period cramps occur when the uterus contracts during menstruation. They can range from mild discomfort to more significant cramping and pain.

Because magnesium contributes to normal muscle function, researchers have investigated whether magnesium may have a role in menstrual discomfort.

Some research has shown potential benefits from magnesium supplementation for menstrual symptoms, although results vary and more research is needed.

Importantly, severe or persistent period pain isn't something that should automatically be attributed to low magnesium. If period pain regularly interferes with everyday life, it's worth discussing with a healthcare professional.

Magnesium & PMS

Premenstrual syndrome, commonly known as PMS, can cause physical and emotional changes in the days leading up to a period.

Common symptoms can include:

Mood changes
Tiredness
Bloating
Breast tenderness
Headaches
Food cravings
Abdominal discomfort

Magnesium has been researched in relation to some PMS symptoms, but it shouldn't be presented as a treatment or cure for PMS.

What we do know is that magnesium contributes to normal psychological function, nervous system function and energy metabolism, making adequate magnesium intake important throughout the entire month.

Do Women Need More Magnesium During Their Period?

Generally, the goal isn't to suddenly increase magnesium only when your period arrives.

Your body requires magnesium every day, so maintaining a consistent intake throughout the month is more important than treating magnesium as something you only think about during menstruation.

Magnesium-rich foods include:

Nuts and seeds
Beans and lentils
Leafy green vegetables
Whole grains
Avocado
Some seafood

A varied diet should be an important source of your daily magnesium.

Using Topical Magnesium Around Your Period

Some women enjoy incorporating topical magnesium into their normal self-care routine around their period.

For example:

Magnesium Oil Spray
Quick and convenient for everyday application.

Magnesium Gel Roll-On
Easy to use when you want targeted application.

Magnesium Bath Flakes
Ideal for adding to a warm bath or foot soak as part of an evening wind-down.

Think of topical magnesium as part of your personal wellness routine, rather than as a treatment for period pain or PMS.

Magnesium During Pregnancy

Pregnancy changes the body's nutritional requirements, making a balanced and nutrient-rich diet particularly important.

Magnesium remains an essential mineral during pregnancy and contributes to normal processes including muscle function, nervous system function, energy metabolism and the maintenance of healthy bones.

Good dietary sources of magnesium include nuts, seeds, legumes, whole grains and leafy green vegetables.

Magnesium While Breastfeeding

Good nutrition remains important after birth, particularly while breastfeeding.

Magnesium continues to contribute to normal muscle and nervous system function, energy metabolism and healthy bones.

A balanced diet containing whole grains, nuts, seeds, legumes and vegetables can help contribute towards daily magnesium requirements.

If you're considering additional magnesium supplements while breastfeeding, take your existing diet and supplements into account and seek professional advice where appropriate.

Magnesium & Perimenopause

Perimenopause is the transitional period leading up to menopause and can begin several years before a woman's final period.

Changing hormone levels during this time can be associated with changes in:

Menstrual cycles
Sleep
Mood
Body composition
Bone health
Muscle mass

This can make perimenopause an important time to pay closer attention to nutrition, exercise, sleep and general wellbeing.

Magnesium remains important because it contributes to normal muscle and nervous system function, psychological function, energy metabolism and healthy bones.

Magnesium & Menopause

Menopause marks an important change in a woman's nutritional and health priorities.

Declining oestrogen levels can influence areas including bone density, muscle mass, body composition and sleep, making healthy nutrition and regular physical activity increasingly important.

Magnesium contributes to several functions relevant during this stage of life.

Magnesium & Bone Health During Menopause

Bone health becomes increasingly important during and after menopause.

The decline in oestrogen associated with menopause can accelerate bone loss, which is why good nutrition and physical activity become particularly important during this stage of life.

Magnesium contributes to the maintenance of healthy bones, but it doesn't work alone.

Bone health is also supported by factors such as:

Adequate calcium
Vitamin D
Sufficient protein
Weight-bearing exercise
Resistance training
Avoiding smoking
Limiting excessive alcohol consumption

Magnesium should therefore be considered as one part of a broader approach to maintaining healthy bones as you age.

Magnesium, Menopause & Sleep

Sleep changes are commonly reported during perimenopause and menopause.

Women may experience difficulty falling asleep, waking during the night or disrupted sleep associated with symptoms such as hot flushes and night sweats.

Magnesium contributes to normal nervous system and psychological function, which is one reason magnesium is frequently incorporated into evening wellness routines.

A simple evening routine might include:

Warm shower or bath → topical magnesium → quiet wind-down time → reduced screens → bed

Magnesium isn't a sleeping medication or treatment for menopausal sleep disturbances, but it can fit naturally into an existing evening routine.

Magnesium, Muscles & Healthy Ageing

Maintaining muscle strength becomes increasingly important as women get older.

Nutrition is only part of the equation. Regular resistance training, physical activity and adequate protein intake are also important for maintaining muscle mass and strength with age.

For active women, topical magnesium can be conveniently incorporated into an existing exercise or evening routine.

Magnesium for Active Women

Magnesium isn't only relevant to particular life stages.

Whether you run, lift weights, play sport, work a physically demanding job or simply enjoy staying active, your muscles and energy systems are constantly at work.

Magnesium contributes to:

Normal muscle function
Normal energy metabolism
Electrolyte balance
Normal protein synthesis

Maintaining an adequate magnesium intake is therefore relevant for women with active lifestyles at virtually every age.

Magnesium, Stress & Busy Lifestyles

Between work, family, exercise and everyday responsibilities, maintaining healthy routines isn't always easy.

Magnesium contributes to normal nervous system function and normal psychological function, but it shouldn't be thought of as a treatment for stress or anxiety.

Instead, focus on the bigger picture:

Eat a varied, nutrient-rich diet
Stay physically active
Prioritise good sleep
Stay adequately hydrated
Make time to unwind
Build routines you can realistically maintain

For women who enjoy topical magnesium, applying it after a shower or before winding down for the evening can simply become another part of that routine.
