Magnesium<\/span><\/a> is an essential mineral used for many functions in the body, and is key for nervous system, heart, and muscle function. Not getting enough magnesium may affect your risk of developing certain diseases, including high blood pressure, cardiovascular disease, Type 2 diabetes, osteoporosis, and migraine headaches. For women in particular, magnesium can play a role in hormone regulation and in preventing osteoporosis in postmenopausal women.\u00a0<\/span><\/p>\n

Though we get most of our magnesium from our dietary sources, some might wonder about <\/span>magnesium supplementation<\/span><\/a> and its benefits. Magnesium can come in forms such as magnesium oxide, magnesium citrate, and magnesium glycinate. Each of these forms may be recommended for a different reason. In this article, learn about magnesium\u2019s function in women\u2019s health, the different forms of magnesium available, and when healthcare providers may recommend them.\u00a0<\/span><\/p>\n

Best magnesium supplement for women<\/span><\/h2>\n

There\u2019s no single best magnesium supplement for all women, but some forms may be better than others. Studies show that all <\/span>magnesium supplements can raise magnesium levels<\/span><\/a> in the body; however, magnesium glycinate, citrate, malate, and L-threonate are generally better absorbed than forms like magnesium oxide. Better absorption means fewer digestive side effects and more reliable benefits.<\/span><\/p>\n

For many women, <\/span>magnesium glycinate<\/span><\/a> is a popular and accessible choice. It\u2019s well absorbed, gentle on the stomach, and widely used for stress, sleep, muscle tension, and overall supporting magnesium levels in the body. <\/span>Magnesium malate<\/span><\/a> may be considered when fatigue or muscle soreness is a concern, while <\/span>magnesium citrate<\/span><\/a> is more often used when constipation is part of the picture. Magnesium L-threonate is typically chosen for its potential neurological benefits.<\/span><\/p>\n

Be cautious with \u201cbuffered\u201d magnesium glycinate products. These usually combine magnesium glycinate with magnesium oxide. Although the label may list a high amount of magnesium, the oxide portion is poorly absorbed, which can limit its effectiveness.<\/span><\/p>\n

Talk with your healthcare provider before starting magnesium supplements. Magnesium can interact with certain medications. For example, antacids that contain magnesium oxide can <\/span>significantly reduce gabapentin absorption<\/span><\/a> if taken at the same time. Your healthcare provider can take into account your individual health conditions and medication history to guide your supplement choices.\u00a0<\/span><\/p>\n

Best magnesium supplement for women over 50<\/span><\/h2>\n

One major concern for women over 50 is <\/span>bone health<\/span><\/a> after menopause. <\/span>Magnesium citrate<\/span><\/a> has been used in studies supporting magnesium\u2019s bone health benefits in postmenopausal women, particularly due to its role in calcium balance and activating vitamin D. For this reason, healthcare professionals may recommend magnesium citrate for postmenopausal women as part of their <\/span>bone density<\/span><\/a> support plan.\u00a0<\/span><\/p>\n

Bone health may not be the only consideration for women over 50. Clinicians may recommend other forms of magnesium depending on their patients\u2019 individual concerns. Choosing the right form depends on symptoms and overall health goals, health status, and other medications, says <\/span>Rupa Salwan<\/span><\/a>, ND, naturopathic doctor and Clinical Director of Wildflower Health and Wellness in Bolton, Ontario, Canada. \u201cFor women over 50, the decision isn\u2019t just about age; it\u2019s about kidney function, medications, and stool patterns. I\u2019m especially careful with dosing and timing when patients are taking thyroid medication, antibiotics, or osteoporosis drugs.\u201d<\/span><\/p>\n

Types of magnesium supplements explained<\/span><\/h2>\n

Not all magnesium supplements work the same way. The form of magnesium can affect how well it\u2019s absorbed, its side effect profile, and which systems in the body it may best support. Here are a few common forms of magnesium supplements and how they compare to each other.<\/span><\/p>\n

Magnesium glycinate<\/span><\/h3>\n

Magnesium glycinate<\/span><\/a> is magnesium chelated with (bound to) the amino acid glycine. It absorbs well in the gut and is generally gentle on the stomach, which is why healthcare providers may recommend it for people who experience digestive problems with other forms of magnesium. \u201cMagnesium glycinate is well absorbed, has calming effects, and is less likely to cause gastrointestinal discomfort, making it suitable for people with sensitive digestion and for long-term use,\u201d says <\/span>Jennifer Pallian<\/span><\/a>, RD, registered dietitian, food scientist, and recipe developer at Foodess.\u00a0<\/span><\/p>\n

Glycine has some effects on the <\/span>nervous system, muscles, and metabolic system<\/span><\/a>. Though more human studies are needed, magnesium glycinate supplements reduced <\/span>anxious behaviors in studies with mice<\/span><\/a>. For these reasons, your provider may recommend magnesium glycinate to support sleep quality, stress, anxiety, or muscle tension.\u00a0<\/span><\/p>\n

Magnesium citrate<\/span><\/h3>\n

Magnesium citrate<\/span><\/a> is a magnesium that\u2019s combined with citric acid or citrate. While it <\/span>does get absorbed<\/span><\/a> through the gut, it can draw water into the intestines, which can lead to a laxative effect or loose stools in higher doses. For this reason, healthcare providers may recommend magnesium citrate for short-term constipation relief. In studies with postmenopausal women, magnesium citrate has been used to support bone density as well.\u00a0<\/span><\/p>\n

Magnesium oxide<\/span><\/h3>\n

Magnesium oxide<\/span><\/a> supplements aren\u2019t generally absorbed well compared to forms such as magnesium glycinate and citrate. Most of the magnesium stays in the gut rather than being absorbed. \u201cIt is mainly used for constipation or acid indigestion rather than for correcting a deficiency,\u201d Pallian says.<\/span><\/p>\n

Because magnesium oxide can neutralize stomach acid, healthcare providers may recommend magnesium oxide-containing antacids (e.g., <\/span>Mylanta<\/span><\/a>) for heartburn. Magnesium oxide may also be used to support regular bowel movements since it can have a laxative effect similar to magnesium citrate.\u00a0<\/span><\/p>\n

Magnesium malate<\/span><\/h3>\n

Magnesium malate is similar to magnesium citrate, where magnesium is combined with malic acid to form magnesium malate. Malate is a compound involved in cellular energy production. \u201cMagnesium malate is best suited for muscle function and has evidence to support its use for those with fibromyalgia,\u201d says Dr. Salwan. In studies with mice, magnesium malate was found to be absorbed more into the brain and muscle cells. Clinicians may consider magnesium malate for people with fatigue, muscle soreness, or conditions such as <\/span>fibromyalgia<\/span><\/a>.\u00a0<\/span><\/p>\n

Magnesium L-threonate<\/span><\/h3>\n

Magnesium L-threonate is a form of magnesium chelated with the amino acid L-threonate. \u201cIt\u2019s the only magnesium that is able to cross the blood-brain barrier and therefore most helpful with mental health issues, including anxiety disorders,\u201d says Dr. Salwan. This form of magnesium has been studied for its effects on brain health, focus, <\/span>sleep<\/span><\/a>, and neurological support. Healthcare providers may consider it for its brain-related benefits on <\/span>memory and cognition<\/span><\/a>.\u00a0<\/span><\/p>\n

Why women need magnesium<\/span><\/h2>\n

Magnesium is involved in more than 300 enzymatic reactions in the body, and many can affect women\u2019s health across different life stages. \u201cBecause it supports so many systems, even marginal deficiency can show up as fatigue, poor sleep, muscle tension, or headaches,\u201d Dr. Salwan says.\u00a0<\/span><\/p>\n

Magnesium levels in women<\/span><\/a> can be significantly influenced by hormonal fluctuations in life stages. \u201cFor women in perimenopause and menopause, magnesium often comes up in conversations about sleep quality, body stiffness, palpitations, and stress resilience. It also plays a supporting role in bone and cardiovascular health as estrogen levels decline in early <\/span>menopause<\/span><\/a>,\u201d Dr. Salwan explains.<\/span><\/p>\n

Hormone balance<\/span><\/h3>\n

Magnesium is a cofactor in many reactions that regulate hormones, for example, thyroid hormones, cortisol (a stress hormone), adrenal function, and estrogen and progesterone metabolism. All of which can impact menstruation cycles, pre-menopausal syndrome (PMS) symptoms, and <\/span>perimenopausal changes<\/span><\/a>, Pallian says.<\/span><\/p>\n

In turn, the different life stages that a woman goes through <\/span>can change their magnesium requirements<\/span><\/a>, which can potentially impact their risk of developing other conditions. For example, low magnesium levels have been associated with inflammatory conditions such as <\/span>polycystic ovarian syndrome (PCOS)<\/span><\/a> and endometriosis, and symptoms of <\/span>depression<\/span><\/a> in postmenopausal people.\u00a0<\/span><\/p>\n

Magnesium also has a role in blood sugar regulation through its effects on the hormone insulin, which can impact women with or at risk of Type 2 diabetes.\u00a0<\/span><\/p>\n

Stress and sleep support<\/span><\/h3>\n

People with low magnesium may experience more irritability, fatigue, and sleep disturbances. Magnesium helps regulate the nervous system by supporting neurotransmitters involved in relaxation. \u201cIt plays a role in neurotransmitter regulation that supports mood stability and neuromodulation,\u201d Pallian explains.<\/span><\/p>\n

Also, magnesium impacts how the body responds to stress through regulating levels of the hormone cortisol. This makes it relevant for women experiencing chronic stress, anxiety, or <\/span>trouble sleeping<\/span><\/a>.\u00a0<\/span><\/p>\n

Bone health<\/span><\/h3>\n

Osteoporosis<\/span><\/a> is a condition that affects mostly women after menopause and puts them at <\/span>higher risk for bone fractures<\/span><\/a> in older adulthood. Though most people think of calcium for bone health, magnesium is also important in <\/span>regulating calcium and vitamin D levels<\/span><\/a>, factors that are key in maintaining bone density.\u00a0<\/span><\/p>\n

\u201cLow serum magnesium is associated with low bone density in both pre- and postmenopausal women, and osteoporotic postmenopausal women have lower magnesium levels than non-osteoporotic women,\u201d Pallian shares.\u00a0<\/span><\/p>\n

Muscle and nerve function<\/span><\/h3>\n

Magnesium is required for proper muscle contraction and relaxation, in addition to nerve signaling. Low levels of magnesium can contribute to muscle cramps, restless legs, twitching, or migraine headaches. Women who exercise regularly, are pregnant, or experience menstrual cramps may have higher magnesium requirements because of the increased muscular demand.\u00a0<\/span><\/p>\n

Heart health\u00a0<\/span><\/h3>\n

Magnesium supports normal blood pressure regulation and blood vessel function. This is important because <\/span>cardiovascular disease (CVD) is the leading cause of death in U.S. women<\/span><\/a>, and their risk for developing CVD increases significantly after menopause. Though stronger studies are needed to make the connection between magnesium supplementation and its effect on blood pressure, there is a strong relationship between low magnesium and poor blood pressure control.\u00a0<\/span><\/p>\n

How much magnesium do women need?<\/span><\/h2>\n

The recommended dietary allowance (RDA) for magnesium ranges from 30 to 400 mg for women, and it changes based on their life stage. An RDA is the average daily amount needed to meet the nutrient requirements of most healthy individuals. Here are the RDAs for magnesium based on a woman\u2019s age:<\/span><\/p>\n
