★ For Tired Moms

Dear Moms, The short fuse isn't you.
It's your cortisol.

The 3am wake-ups. The afternoon crash. The voice that snaps before your brain can stop it. You're running low on the one mineral your brain can't function without.

What Happens After You Start Prime Mag™
Day 7 Awaken
  • Brain starts to rehydrate with bioavailable magnesium
  • First night of uninterrupted sleep by day 4-5
  • The 3am wake-ups begin to space out
  • Afternoon energy feels more stable
Day 30 Restore
  • Brain fog lifts, mornings feel sharp again
  • The 2pm crash stops showing up
  • Cortisol response softens, mood evens out
  • Your partner says "you seem different"
Day 90 Bloom
  • New baseline locked in, sleep scores trending up
  • Deep sleep averaging 1hr 20min nightly
  • HRV climbing, resting heart rate dropping
  • You feel like yourself again
How long until I see results?
Week 1: subtle shifts in sleep quality. Many report sleeping through the night by day 4-5. Month 1: brain fog clears, the 2PM crash stops. Month 2: stress response improves, people around you notice. Month 3: new baseline locked in.
What's inside and why does it work?
Prime Mag contains four clinically-dosed forms of magnesium plus active Vitamin B6 (P-5-P). L-Threonate (2,000mg) crosses the blood-brain barrier. Bisglycinate (550mg) for sleep and cortisol. Malate (300mg) for cellular energy. Taurate (100mg) for cardiovascular support.
How is this different from glycinate I'm taking?
Your glycinate is helping your muscles relax. But it can't reach your brain. The blood-brain barrier blocks most magnesium forms. Prime Mag includes Bisglycinate (so you keep what glycinate gives you) plus L-Threonate, the only form with a published RCT showing it crosses the blood-brain barrier.
How does the subscription work?
Your first bottle ships immediately. A fresh bottle auto-ships every 4 weeks at $49.95 with free shipping every time. You can skip, pause, or cancel from your account portal anytime with one click.
Can I cancel anytime?
Yes. One click from your account dashboard cancels or pauses your subscription instantly. No retention team, no hold music, no hoops to jump through.
What's the 90-Day Guarantee?
Try Prime Mag for 90 nights. If you don't feel a difference, send it back (even empty) for 100% of your money back. No forms, no questions, no hassle.
Who is Prime Mag for?
Moms, women over 30, and anyone with high cortisol, poor sleep, brain fog, or who's tried other magnesiums and still can't get past the 3am wake-ups. If you're pregnant, breastfeeding, or on medication, consult your doctor first.

"Finally sleeping through the night."

I'm 42 and had been waking at 3am every single night for two years. Tried magnesium glycinate, melatonin, CBD. Nothing worked. Prime Mag changed everything by week 2. I wake up at 6am naturally now.

★ ★ ★ ★ ★
"The afternoon crash stopped."

Every day at 2pm I'd hit a wall. Needed coffee just to function until dinner. Two weeks on Prime Mag and the crash just... didn't happen. I'm getting through workdays without the second coffee.

★ ★ ★ ★ ★
"Oura sleep score jumped 20 points."

Data doesn't lie. 18 days in and my sleep score went from 68 to 86. Deep sleep averaging 1hr 40min. First magnesium that actually moved my biometrics.

"I'm not snapping at my kids anymore."

The short fuse was the worst part. I hated who I was becoming. Three weeks in and I actually have patience again. My husband said "you're back."

★ ★ ★ ★ ★
"Brain fog is gone."

I'm a project manager and was losing words mid-sentence. Doctor said my bloodwork was "normal." Turns out blood tests only check 0.3% of your body's magnesium. Two weeks on Prime Mag and I'm sharp again.

From a Mom to Moms

"I tried every magnesium on the shelf. I still woke up at 3am with my heart pounding."

Seven forms of magnesium exist. Six of them never reach your brain. They settle in your gut, do a small job, and leave through the bathroom. You pay for expensive pee.

The seventh form was developed by scientists at MIT. It's the only one small enough to slip past the blood-brain barrier. It raises magnesium inside the brain by 15%. That's where the sleep lives. That's where the calm lives. That's where you live.

We built Prime Mag™ around it. No fillers. No cheap oxide. No hidden "proprietary blends." Just the form your brain has been begging for, at the dose the research actually used.

Emma Collins
The Problem

Your magnesium is feeding your body. Your brain is still starving.

45% of Americans are magnesium deficient. But here's what most people miss: even if you're supplementing, the form you're taking probably can't reach the organ that needs it most.

Your body can only absorb so much at once. Take too much of one form and most of it never makes it into your cells. It just passes through.

But that's not the real problem.

Your brain is protected by the blood-brain barrier. Most magnesium forms get stopped at the gate. Your legs feel better. Your cramps ease up. But the fog at 2PM, the anxiety that won't shut off, the 3AM wake-ups all originate in your brain. Your magnesium never arrived.

Stress makes it worse. Cortisol burns through magnesium. Lower magnesium means higher cortisol sensitivity. The cycle accelerates until sleep, focus, and mood all break down together.

Blood brain barrier
The Fix

I'm 62. My daughter thought I was getting dementia. I wasn't.
Customer photo
I was forgetting names. Losing my car in parking lots. My daughter gently suggested I see a neurologist. That scared me more than anything has in years. Apparently most magnesium doesn't even get to your brain. Last week I remembered my new neighbor's name, her husband's name, and what she did for work three days after our first conversation. My daughter saw my face. She looked relieved.

Oura sleep score: 68 to 86 in 18 days
Customer photo
I track everything. My sleep score had been stuck in the mid-60s for months. Day 4: first night of uninterrupted deep sleep over 1hr 40min. By day 18 my sleep score hit 86. HRV went from 34 to 51. The L-Threonate is the differentiator. This is the first magnesium that made my brain feel different, not just my muscles.

The 3PM brain fog just... stopped
Customer photo
I'm a project manager. The past year I've been losing words mid-sentence. My doctor said everything was fine. But "normal" blood tests only check 0.3% of your body's magnesium. Two weeks in and I'm reading reports without re-reading the same paragraph. The 3PM fog that used to roll in like clockwork just didn't show up one day. I cried in my car that week. Because I realized how much I'd been losing without knowing it.

ER nurse. The only thing that's helped my cortisol.
Customer photo
12-hour night shifts for 6 years. My cortisol is always high. I've tried ashwagandha, L-theanine, CBD. Nothing touched it. I'm a nurse. I read the studies, not just marketing. Six weeks in: resting heart rate is 71. That's a 7 BPM drop. My coworkers asked what I changed. I told them magnesium and they laughed. They're not laughing anymore.
