Magnesium: The Mineral Most Women Are Deficient In (And Don't Know It)

If there's one nutrient I talk about more than almost any other in my coaching practice, it's magnesium. Not because it's trendy — though it has certainly had its moment in the wellness spotlight — but because the evidence for its importance is overwhelming, the deficiency is genuinely widespread, and the symptoms of low magnesium are so common that most women have simply accepted them as normal.

They are not normal. And once you understand what magnesium actually does in your body, you'll understand why getting enough of it is one of the most foundational things you can do for your health.

What Magnesium Does (The Short Version)

Magnesium is involved in over 300 enzymatic reactions in the human body. That's not a typo — three hundred. It plays a role in energy production, protein synthesis, muscle and nerve function, blood glucose regulation, blood pressure regulation, and the synthesis of DNA, RNA, and the antioxidant glutathione. It is also required for the activation of vitamin D — which means that if you're taking vitamin D supplements but are magnesium deficient, you may not be absorbing that vitamin D effectively.

For sleep specifically, magnesium regulates the neurotransmitter GABA (gamma-aminobutyric acid), which is the brain's primary calming chemical. Low magnesium means low GABA activity, which means a nervous system that struggles to downshift into rest mode — regardless of how tired you feel.

Why So Many Women Are Deficient

The modern food supply is significantly lower in magnesium than it was 50–100 years ago, primarily due to soil depletion from industrial farming practices. Whole grains, leafy greens, nuts, and seeds are the richest dietary sources — but many women eat diets that are low in these foods and high in processed foods that contain virtually no magnesium.

Several common factors actively deplete magnesium from the body: chronic stress (the adrenal glands burn through magnesium at a rapid rate when we're stressed), alcohol consumption, caffeine, certain medications (including proton pump inhibitors, diuretics, and some antibiotics), and high sugar intake. This means that the very lifestyle factors most associated with modern stress and fatigue are also the ones most likely to drain your magnesium stores.

For women in perimenopause and menopause, the picture is even more complex. Declining estrogen levels affect magnesium absorption and distribution in the body, making older women particularly vulnerable to deficiency.

Signs You May Be Low in Magnesium

The symptoms of magnesium deficiency are so common and so varied that they often get attributed to other causes — or simply accepted as "just how I feel." Watch for these signs:

Muscle cramps and spasms (especially leg cramps at night) are one of the most classic signs. Magnesium is essential for muscle relaxation — calcium causes muscles to contract, and magnesium causes them to release. Without enough magnesium, muscles can't fully relax.

Poor sleep and insomnia are strongly associated with low magnesium, particularly difficulty staying asleep and waking in the early hours. Anxiety and a sense of being "wired but tired" — unable to relax even when exhausted — is another hallmark. Headaches and migraines have been linked to low magnesium in multiple studies; some neurologists now routinely check magnesium levels in migraine patients. Constipation, heart palpitations, sensitivity to noise, and a general sense of tension or tightness throughout the body can all point to magnesium insufficiency.

Food Sources First

Before reaching for supplements, let's talk about food. The richest dietary sources of magnesium include pumpkin seeds (the single highest food source — one ounce provides about 37% of the daily value), dark leafy greens like spinach and Swiss chard, almonds and cashews, black beans and lentils, avocado, dark chocolate (70% or higher), whole grains like quinoa and brown rice, and bananas.

A practical goal: aim to include at least two or three magnesium-rich foods in your diet every day. A handful of pumpkin seeds on your morning yogurt, a big spinach salad at lunch, and a square of dark chocolate in the evening is a genuinely pleasant way to support your magnesium levels.

When to Consider Supplementation

For many women, food alone may not be sufficient — especially if you're dealing with chronic stress, sleep problems, or muscle tension. Magnesium supplements are generally very safe and well-tolerated, but the form matters enormously.

Magnesium glycinate is my top recommendation for most women. It's highly bioavailable, gentle on the digestive system, and particularly effective for sleep, anxiety, and muscle tension. Magnesium malate is excellent for energy and muscle pain. Magnesium citrate is effective but has a laxative effect at higher doses — useful for constipation, but not ideal for sleep support. Avoid magnesium oxide, which is poorly absorbed and primarily useful as a laxative.

A typical therapeutic dose for sleep and relaxation is 200–400mg of magnesium glycinate taken 30–60 minutes before bed. Always start at the lower end and work up gradually. Consult your healthcare provider if you have kidney disease, as magnesium is processed by the kidneys.

A Gentle Invitation

If you've been living with muscle cramps, restless nights, anxiety, or that persistent sense of tension that never quite releases — please don't accept that as your baseline. Your body may simply be asking for more of this essential mineral. Start with food, add a quality supplement if needed, and give it 4–6 weeks to notice the difference.

You deserve to feel genuinely relaxed in your own body. Magnesium is one of the most accessible paths there.
