An essential mineral involved in hundreds of biological functions — energy production, muscle contraction, nervous-system regulation. And for women, from sleep to stress to pregnancy, research suggests magnesium plays a vital role at every stage of life.
A valuable ally at every life stage — here’s what the research suggests, with the dose ranges and forms our practitioners reach for.*
Polycystic ovary syndrome affects up to an estimated 6 million American women. Research suggests magnesium may influence insulin sensitivity and inflammation, both involved in PCOS — alongside other dietary and lifestyle interventions.
Magnesium is believed to help relax uterine muscles by influencing calcium regulation and prostaglandin synthesis. Some studies show regular supplementation may help reduce the severity of menstrual discomfort.
Studied for its role in mood and fluid balance, magnesium may help ease emotional and physical symptoms of PMS — bloating, irritability, fatigue — especially when paired with vitamin B6.
Magnesium supports reproductive health through hormone regulation and energy metabolism, plays a role in follicular development and ovulation, and is believed to be essential in early pregnancy.
During pregnancy, magnesium supports fetal development and maternal well-being through blood-pressure regulation and healthy muscle and nerve function. Requirements increase, especially in the second and third trimesters.
Alongside calcium and vitamin D, magnesium helps support bone mineral density. Low intake has been associated with increased osteoporosis risk after menopause — part of a broader bone-health strategy.
Magnesium helps regulate muscle function and neuromuscular transmission, and may ease occasional tightness — after exercise, around the cycle, or during pregnancy.
Stress can deplete magnesium stores, and low levels may influence the body’s stress response. Research shows magnesium may support a healthy stress response by modulating the HPA axis and promoting nervous-system balance.
Women experience more sleep disturbance than men, especially through hormonal transitions like perimenopause. Magnesium interacts with GABA receptors that promote relaxation, and may improve sleep quality where levels are low.
Magnesium keeps working with age — muscle function, bone maintenance, cardiovascular health. Absorption declines over time, making intake worth watching later in life. RDA: 350 mg/day (19–30), 360 mg/day (31+).
