Calm your cortisol, one hour of the day at a time
Six changes women are making, from the first coffee to lights out. The first one comes first for a reason.

Which of these sounds like you?
Tap the ones that fit. If two or more do, cortisol is a good place to look.
Show me what's going onStress and magnesium feed each other
Cortisol is your main stress hormone. It's meant to peak in the morning and be low by bedtime. Stress keeps it switched on, and stress also uses up magnesium. Low magnesium then makes stress harder to switch off.2 So the more stressed you are, the less you have left to calm down with.
That's why this list starts with magnesium. The five changes after it are about holding on to what you've got, hour by hour.
Take magnesium bisglycinateThe mineral your body uses to calm the stress response. Everything else on this list protects it. This is the one that puts it back.
In a small placebo-controlled trial in older adults, magnesium improved sleep and lowered cortisol.7 The catch is the form. Most magnesium on the shelf barely gets in.
Tried magnesium and felt nothing?
Check the label for one word: oxide. It's the cheapest form, and in one study only about 4% of it was absorbed.4

Many older adults in the US aren't getting enough magnesium from their diet alone. Thankfully, two of these gummies can provide a full day's serving.
Eat breakfast before coffeeCaffeine on an empty stomach works against you
Coffee nudges cortisol up, and caffeine sends more magnesium out through your kidneys for a few hours after each cup.8,9 First thing, with nothing else in your stomach, that's a rough start for a body that's already running low.
Swap some HIIT for walks and strengthVery hard workouts burn through magnesium
Hard, high-intensity sessions push cortisol up, and training hard raises how much magnesium you lose through sweat and urine.10,11 When you're already stretched, more intensity can work against you.
Starting with change 1?
Most women give it 90 nights. 3 bags, a free D3 + K2, from $1.17 a night.
Start my 90 nightsCut the 4 pm sugar fixSugar spikes cost you magnesium
The afternoon sweet hit feels like a lift, then the crash feels a lot like stress. Sugar also raises how much magnesium your kidneys let go.12
Put magnesium on your plateHelpful, but rarely enough on its own
Pumpkin seeds, almonds, spinach, black beans and dark chocolate are all good sources.1 Worth adding. But many adults already eat less magnesium than they need, and stress keeps spending what's there.1,2
Protect your wind-down hourIt's when cortisol is meant to drop
Cortisol should be at its lowest around bedtime. A short night keeps it higher the next evening, and the loop starts again.6
And this is where change 1 lives: two gummies, 30 to 60 minutes before bed. Then the day starts again. Back to change 1
Five changes protect your magnesium. One puts it back.
Start with the gummies, then add the change that feels easiest. Give it 90 nights. The goal: calmer days, less bloating, and a belly that finally starts to respond.
"I wish someone had told me years ago."
from 12,470+ reviews and 120K+ customers
SPNutrition survey of 1,200 customers taking 2 gummies daily for 2 weeks. Self-reported.
My bloodwork was normal. I felt anything but. My doctor told me it was just stress. Falling asleep before 11pm for the first time in years. I wish someone had told me years ago.
On really stressful days, it helps me wind down and sleep like a rock. Best decision ever!
Tried magnesium THREE times. Then I learned about oxide vs bisglycinate. First week on SPNutrition? Sleeping through the night. I feel like myself again.
I had tried two magnesium pills and felt nothing. Within three weeks of switching, brain fog was almost gone. I went from surviving to functioning.
I switched from magnesium citrate and the difference is night and day. These gummies are so gentle I forget I'm even taking a supplement.
From waking up four times a night for two years, to sleeping until the alarm. I did not know how much I missed feeling rested.

Give it 90 nights
Give it 30 nights before you judge it, and three months to see what it really does. That's why most women go with 3 bags.
Feel calmer, or it's free
If you don't notice a difference, email us. We'll refund every penny, and you keep the bags. Less than 2% of customers ever ask.
Before you start
Will this help me lose weight?
It isn't a weight-loss product, and no gummy melts belly fat. Magnesium supports the stress-and-sleep side of the picture, which is what this list is about. The other five changes help with the rest.
Do I have to do all 6?
No. Start with change 1, then add the one that feels easiest. One small habit you keep beats a perfect week you can't repeat.
Can I take it with HRT?
Hormone therapy isn't among the known magnesium interactions, and many women take both. Magnesium can affect how some other medicines are absorbed, including certain osteoporosis drugs, antibiotics, diuretics and acid reducers, so check timing with your doctor or pharmacist if you take any of those.1
How soon will I notice something?
Give it 30 nights before you judge it, and three months to see what it really does. Magnesium works by topping up what your body is short on, so it builds with daily use.
Who should check with a doctor first?
Anyone with kidney disease, or anyone on prescription medication, should talk to their doctor before starting magnesium.
