Women over 40 often juggle hormonal shifts or, rising stress levels, and even sleep disturbances. Amid these midlife changes, one essential nutrient is frequently overlooked: Magnesium/Mg . This humble mineral plays a starring role in countless bodily functions, yet many women don’t realize they’re not getting enough. When magnesium levels run low, you might experience fatigue, mood swings, restless sleep, or muscle aches without understanding why.
Midlife hormonal changes (like perimenopause and menopause) and a busy lifestyle can actually deplete magnesium levels. In fact, it’s estimated that more than half of adults don’t get the recommended amount of magnesium from diet alone.
So, why is magnesium so important for women in their 40s, 50s, and beyond? And how can you easily restore optimal levels?
Let’s dive into the benefits of magnesium:

Why Magnesium Matters More After 40

As we age, our bodies undergo changes that make getting enough magnesium even more necessary and important. Hormonal fluctuations in perimenopause and menopause can wreak havoc on mood, sleep, and bone health (areas where magnesium is a key player). Magnesium helps regulate neurotransmitters & hormones that influence stress and sleep (such as cortisol and melatonin). Sufficient magnesium can ease the transition through menopause. It’s no wonder magnesium is often called a “menopause superhero” for its ability to alleviate symptoms like insomnia and mood swings.
On top of that, many women reduce their calorie intake in midlife or rely on convenience foods, which can lead to insufficient magnesium in the diet. The result? By your 40s or 50s, you’re at higher risk of running a magnesium deficiency even with a healthy diet. Older adults have relatively low magnesium intakes, and aging bodies may excrete more of this mineral.

Magnesium deficiency symptoms can significantly affect your quality of life. Common signs include 1. constant fatigue, 2. low energy, 3. frequent muscle cramps or spasms (like leg cramps). 4. trouble sleeping or staying asleep, and even 5. mental health changes like irritability, anxiety, or mood swings.
If you often feel exhausted but unable to relax, magnesium insufficiency could be playing a role. Unfortunately, these issues are often written off as just “getting older” or blamed on hormones when really a simple nutrient fix might help.
Next, we’ll look at exactly what benefits magnesium provides for women in this stage of life:

Magnesium’s Health Benefits

Here are some of the top health benefits of magnesium for women over 40:

1. Supports Relaxation & Reduces Stress

Magnesium is often nicknamed the “relaxation mineral” for good reason. It helps calm the nervous system & regulate the body’s stress response. Sufficient magnesium can actually lower cortisol (the stress hormone) by modulating the HPA axis.
Many women report feeling more at ease and less irritable when their magnesium levels are up. If stress relief is a priority (for many of us!), magnesium might be your new best friend.

2. Promotes Restful Sleep

Are you struggling with insomnia or restless nights? Sleep disturbances become more common during perimenopause and menopause.
Magnesium can improve sleep quality in several ways. It helps regulate melatonin, the hormone that controls your sleep-wake cycle and relaxes your muscles so you can drift off more easily. Research has shown that magnesium supplementation can support healthy circadian rhythms and better deep sleep, partly by easing muscle tension.

3. Eases Muscle Cramps & Supports Joint Health

Have you ever woken up with tense neck and shoulder muscles? Magnesium (Mg) is vital for proper muscle function and relaxation. A lack of Mg can lead to muscle cramps, spasms, or twitching. Middle-aged women, especially those staying active or dealing with menopausal changes, often notice more muscle stiffness or achiness. Mg acts as a natural muscle relaxant, helping to prevent cramps and soothe tightness. It also contributes to healthy nerve function.

4. Boosts Energy & Metabolism

Fatigue and slowing metabolism are common complaints after 40. Here’s where magnesium’s role in energy production becomes important. Magnesium is a co-factor in converting the food you eat (carbs, protein, and fats) into usable energy (ATP) at the cellular level.
When magnesium is low, you literally can’t efficiently generate energy, leaving you dragging through the day. Getting enough magnesium supports a healthy metabolism and steady energy levels. It also aids in maintaining normal/healthy blood sugar and insulin sensitivity.

5. Enhances Cognitive Function

Brain fog and memory lapses don’t have to be an inevitable part of aging. Mg (Magnesium), particularly in the form of Magnesium L-Threonate (Magtein®), has exciting benefits for the brain. This special form of magnesium can cross the blood-brain barrier and elevate magnesium levels in the brain, which is linked to better neural function. Studies have found that Magnesium L-Threonate can improve memory, focus, and learning in older adults.

6. Supports Bone & Heart Health

Women over 40 know that bone density and heart health become top concerns as estrogen levels drop. Magnesium is a quiet workhorse in both these areas. About 60% of the body’s magnesium is stored in our bones, and it works hand-in-hand with calcium + vitamin D to keep bones strong. Magnesium deficiency is associated with lower bone density & strength and even osteoporosis risk because low magnesium can impair vitamin D activation and parathyroid hormone. Considering heart disease risk increases after menopause, magnesium is an important part of supporting a healthy heart. It keeps your heart muscle functioning optimally.

    Mag Calm contains Magtein®, the only magnesium compound clinically shown to significantly raise brain magnesium levels. This is the form responsible for those cognitive benefits like improved memory and focus. Mag Calm helps support your brain health along with your body. In one study, adults who took Magtein daily saw significant improvements in cognitive tests, especially among participants.
  • Albion® Magnesium Bisglycinate Chelate {Superior Absorption, Gentle on Digestion}
    Ever take a cheap magnesium supplement and end up with an upset stomach? That won’t happen with Mag Calm ! It uses Albion® Magnesium Bisglycinate, a highly absorbed chelated form of magnesium. Chelation attaches magnesium to glycine, enhancing its absorption by allowing it to move more efficiently through the digestive system. This form is scientifically proven to be easier on the stomach and less likely to cause the laxative effect that some magnesium supplements do. In short, you get more magnesium into your system where you need it without the GI discomfort. So you can stay consistent with your supplement.
  • Calming GABA & L-Theanine Added
    Each serving also provides GABA (a neurotransmitter that promotes a calm + relaxed mood) & L-Theanine (an amino acid that encourages relaxation and smooth focus (from green tea)). GABA directly helps settle your brain’s activity, easing anxious feelings, while L-Theanine boosts alpha brain waves associated with relaxation without drowsiness.

How to Take Magnesium for Best Results

To get the most out of magnesium, consistency and timing are key. This can come from diet, supplements, or a combination of both.
For best results, take Mag Calm in the evening. Magnesium is fantastic for relaxation, so taking it about an hour before bed can enhance its sleep-supporting effects. Vitauthority specifically recommends taking 3 capsules of Mag Calm at night.
If you prefer, you can split the dose (for example, one(1) capsule with dinner and two(2) before bed), but taking the full serving in the evening is easy and effective for most people.
Additionally, try to pair your magnesium routine with other healthy habits: stay hydrated, eat magnesium-rich foods (leafy greens, nuts, etc.), and practice good sleep.
