Magnesium in Midlife: The Unsung Hero of Women’s Health
Anna Harrelson • July 12, 2025
Why this mighty mineral matters for your mood, metabolism, muscles, and more—especially in perimenopause and beyond.

You know how people say, "Just drink some water and take a magnesium supplement" like it’s the answer to everything? Well… they’re not totally wrong. But like most good advice, the devil is in the details.
Magnesium is one of the most essential minerals in the body, involved in over 300 enzymatic reactions, yet it remains one of the most commonly overlooked deficiencies in midlife women.
And no, your annual bloodwork probably didn’t catch it.
So What Does Magnesium Actually Do?
Think of magnesium as a multitasking background assistant—it keeps the lights on and the gears turning across nearly every body system:
- Brain & Mood: Regulates GABA and NMDA receptors, supporting calm, focus, and resilience against anxiety and overstimulation.
- Muscles: Prevents cramping and twitching, supports strength and recovery, and reduces restless legs.
- Sleep: Plays a role in melatonin production and nervous system regulation.
- Bowel Function: Helps pull water into the colon to prevent constipation.
- Cardiovascular Health: Regulates blood pressure and helps with vasodilation.
- Hormone Balance: Assists in estrogen metabolism and combats insulin resistance.
In short:
if you’re exhausted, bloated, moody, foggy, tense, or irregular in your gut or cycle—magnesium deserves a spot on your radar.
Why Is Magnesium So Important in Midlife?
Estrogen and progesterone both influence magnesium levels. As hormone levels decline or fluctuate during perimenopause and menopause, so does your ability to retain and utilize magnesium.
Add to that:
- Chronic stress (which depletes magnesium)
- Modern diets (often low in magnesium-rich whole foods)
- Medications like PPIs, diuretics, or certain antibiotics
- High caffeine, sugar, or alcohol intake (all increase magnesium excretion)
And suddenly, a "borderline magnesium issue" becomes a perfect storm.
Why Your Blood Test Might Not Show It
Serum magnesium tests only reflect ~1% of total body magnesium. Most magnesium is stored in bone and tissue. So it’s very possible to have "normal labs" and still be clinically deficient.
In practice, we go by symptoms, risk factors, and therapeutic response.
Common Signs of Suboptimal Magnesium
- Trouble falling or staying asleep
- Anxiety or nervous system overactivation
- Fatigue or burnout that doesn’t resolve with rest
- Muscle cramps, spasms, or eye twitches
- Constipation
- Menstrual migraines or tension headaches
- Joint stiffness or tightness
- Sugar cravings or blood sugar crashes
Best Food Sources of Magnesium
Magnesium-rich foods include:
- Dark leafy greens (spinach, chard)
- Nuts and seeds (especially pumpkin seeds and almonds)
- Avocados
- Legumes
- Dark chocolate (yes, really!)
- Whole grains like quinoa and oats
That said, many of us still fall short even with a healthy diet, especially during high-stress seasons or if absorption is impaired.
Supplements: Which Type of Magnesium Is Best?
Not all magnesium is created equal. Here are the forms we most often recommend:
- Magnesium Glycinate: Best for sleep, anxiety, and muscle relaxation. Gentle on the stomach.**
- Magnesium Citrate: Useful for constipation, but can cause loose stools at higher doses.
- Magnesium Threonate: May support cognitive function and brain health.
- Magnesium Malate: Good for energy and muscle pain, often used in fibromyalgia.
We generally avoid magnesium oxide unless constipation is the only concern, as it’s poorly absorbed.
**Mag Glycinate is generally my go to recommendation and what we take at our house
Also, BLENDS can be good- but generally more expensive
Dosing & Timing
- Most women benefit from 200–400 mg daily, depending on needs.
- Take it in the evening if you're targeting sleep or relaxation.
- Divide doses if taking more than 300 mg (e.g. AM + PM).
- Always start low and go slow, especially with citrate forms to avoid urgent bathroom visits.
Final Thoughts
If magnesium had better marketing, it would be a top-tier wellness darling. But because it’s quiet, essential, and boring on paper, we tend to overlook it.
Yet for so many midlife women, magnesium is the missing link that helps all the other systems and strategies finally click.
So if you're doing "everything right" and still feel off? It might be time to start taking magnesium!

"Is Ozempic safe?" "Do I have to be diabetic to use it?" "Will I regain weight if I stop?" "I eat well, lift weights, sleep, take hormones—and I still can't lose weight. What's going on?" These are some of the most common questions I hear from women in midlife. And they’re incredibly valid. For decades, the conversation around weight and health has been riddled with shame, assumptions, and surface-level advice. But we’re finally shifting into a new era—one that recognizes obesity as a chronic, complex disease, not a personal failure. One that looks at metabolism through the lens of hormones, inflammation, genetics, stress, and brain chemistry, not just calories in and out. And at the center of this shift is an exciting class of medications known as GLP-1 receptor agonists. What Are GLP-1 Medications? GLP-1 stands for glucagon-like peptide-1, a hormone your body naturally produces in the gut. It helps regulate blood sugar, insulin, and satiety (your sense of fullness). GLP-1s also slow gastric emptying and signal your brain to reduce appetite. Medications like semaglutide (Ozempic, Wegovy), liraglutide (Saxenda, Victoza), and tirzepatide (Mounjaro) mimic this hormone and have been revolutionary for treating type 2 diabetes—and more recently, for metabolic syndrome and obesity. These drugs are not stimulants or fad diet tools. They are hormone-based medications with powerful metabolic and anti-inflammatory effects. Why Are GLP-1s So Relevant for Midlife Women? Midlife is a time of massive hormonal transition. Estrogen, progesterone, and testosterone levels shift dramatically in perimenopause and menopause. This impacts insulin sensitivity, body composition, lipid metabolism, sleep, inflammation, and brain function. Even women who have optimized their lifestyle—dialing in nutrition, strength training, sleep, and hormone therapy—may find themselves stuck. GLP-1 medications can be the missing piece for women who: Have insulin resistance or prediabetes that isn’t budging with lifestyle alone Carry weight disproportionately in the visceral (abdominal) area Are at increased cardiovascular risk due to family history, labs, or existing conditions Are experiencing significant inflammation or joint pain related to metabolic dysfunction Have a history of PCOS or gestational diabetes Are postmenopausal and noticing rapid changes in weight or metabolism These medications work synergistically with hormone therapy and can reduce inflammation, improve insulin sensitivity, and help shift body composition. For some women, they are as life-changing as starting estrogen. It’s Not Just About Weight Loss GLP-1s are being studied for NAFLD (fatty liver), cardiovascular protection, neurodegenerative disease, PCOS, and even addiction and mood regulation. The benefits go far beyond the scale. That said, when stubborn weight is a major barrier to living fully—whether due to physical discomfort, comorbidities, or psychological toll—helping a woman reduce weight safely and effectively can open the door to movement, joy, and hope. So, Who Should Consider a GLP-1? I don’t believe in prescribing these meds as a first-line for someone who hasn’t addressed the basics. That’s not judgment—it’s strategy. If you haven’t worked on: Blood sugar balance through real food Resistance training and daily movement Addressing sleep and circadian rhythms Managing stress and nervous system regulation Optimizing hormones, micronutrients, and gut health … then you’re not giving yourself the best shot at lasting change. But if you have done the work and still feel like your body is working against you—or you have serious metabolic risk factors— then GLP-1 therapy might be a wise and evidence-based next step. Some women use it briefly to reset. Others may need it long-term, just like hormone therapy. It’s not a crutch. It’s a tool. And for the right woman, it can be life-changing. Common Questions I Hear "Will I gain the weight back if I stop?" Maybe—but not always. If the lifestyle foundations are in place, many women maintain progress even after discontinuing. But some women have chronic conditions that benefit from ongoing use. That’s not failure—that’s biology. "Are there side effects?" Yes. The most common are nausea, constipation, or bloating early on. Starting slow, staying hydrated, and eating smaller portions helps. Rare but serious risks exist, including pancreatitis. A good clinician will walk you through these carefully. "Will I lose muscle?" You can—unless you’re strength training and eating enough protein. We talk a lot about this at Wondercreek. Protecting lean muscle is critical. "Is this forever?" Not necessarily. Some women use these meds to reduce inflammation, restore insulin sensitivity, and break a cycle. Others stay on them longer due to underlying metabolic dysfunction. Every plan is individualized. Final Thoughts GLP-1 medications aren’t for everyone. But they are not cheating, shameful, or lazy. They’re a legitimate, science-based treatment for a serious, chronic condition. In my practice, we focus on healthspan—not just lifespans. That means preserving function, preventing disease, and helping you feel energized, sharp, and resilient for as long as possible. For some women, GLP-1 therapy is one of the most powerful tools we have to get there.

You’ve probably seen it popping up in wellness podcasts, health stores, or even your friend's supplement cabinet: bovine colostrum. Marketed for gut health, immune support, and recovery, this early-life nutrient source for calves is now showing up in adult wellness routines. But is it worth your time and money? As a lifestyle medicine physician focused on women’s midlife health and longevity, here’s what I want you to know before you jump on the colostrum bandwagon. Let’s Start With the Basics: What Is Colostrum? Colostrum is the first form of milk produced by mammals (including humans) in the first few days after giving birth. It’s loaded with antibodies, growth factors, and immune-modulating compounds designed to jumpstart a newborn’s immune system and line the gut. Bovine colostrum—from cows—is the form used in most supplements. It's freeze-dried and packaged into powders or capsules, and often promoted for: Gut barrier support ("leaky gut") Immune system priming Exercise recovery Anti-aging benefits But let’s be honest: just because something has growth factors doesn’t mean it belongs in your Amazon cart. Does the Science Support It? Evidence in humans is limited— but not nonexistent. Some small clinical studies have shown potential benefits: Gut health: In people with NSAID-induced intestinal permeability ("leaky gut"), bovine colostrum has been shown to reduce damage and symptoms. Immune function: Some data in athletes suggests reduced upper respiratory infections. Exercise recovery: A few studies report improvements in performance, gut comfort, or muscle soreness—especially in endurance athletes. But these benefits aren’t guaranteed. And the quality and dosage of colostrum varies widely, with no standardized formulation across brands. So Should You Take It? Here’s where my clinical voice kicks in: Before you reach for colostrum, ask yourself: Have you addressed the basics? Are you sleeping? Managing stress? Eating fiber and whole foods? Getting enough protein? Building muscle? Moving your body? Supporting your gut with real food (not just powders)? If the answer is no—then colostrum is not your next step. You’re throwing powdered fuel on an engine that’s missing spark plugs. Do you have dairy sensitivity? Colostrum is a dairy product. Even if it's low in lactose, it may not be tolerated by everyone. Are you already taking quality foundational supplements? Vitamin D, omega-3s, magnesium, creatine, iron (when needed), and probiotics have stronger bodies of evidence for many women in midlife. When Might It Be Worth Trying? Colostrum might be a reasonable add-on if you: Have mild gut symptoms (especially post-infectious or stress-related) Are recovering from illness or antibiotics Train hard and experience frequent upper respiratory issues Want to support your immune system during travel or stress Even then, I recommend: A 2–3 month trial only after dialing in basics Choosing a third-party tested brand Tracking symptoms and benefits Cost, Hype, and the Bigger Picture Many women I work with are overwhelmed by supplement costs. Colostrum can run $50–100/month —and that adds up. So here’s what I tell my patients: Just because something is trending doesn’t mean it’s essential. And just because it works for someone on TikTok doesn’t mean it’s the right tool for your body right now. Your body is an incredible machine. When you give it rest, movement, nourishment, and support—it can do amazing things. Colostrum is not magic. It’s just one tool in a very big toolbox. Bottom Line Colostrum may hality sources. You’re not broken. You might just need a reset—not another powder.
