7 Signs Your Body Is Low in Magnesium After 40 (And Why It's Easy to Miss)
Most women think it’s “just age” — but one simple mineral plays a bigger role in stress, sleep, and calm than people realize.
1. You feel “tired but wired” at night
You’re exhausted… until you actually get into bed.
Your mind won’t switch off. Your body feels restless. You toss, turn, and stare at the ceiling.
Many women assume this is hormonal...
But stress slowly drains magnesium, the mineral that helps your body relax in the evening.
2. You sleep lightly, wake up during the night, and can’t fall back asleep
This is one of the most overlooked signs of low magnesium.
Women describe it as:
“My brain just turns back on.”
When magnesium levels dip, it becomes harder for the nervous system to stay calm through the night.
3. You feel more anxious or irritable than you used to
Not “clinical anxiety” — just a lower stress threshold.
You snap quicker.
You feel overstimulated.
Little things set you off.
It’s not personality change. It’s not “just age.”
Low magnesium = less emotional resilience.
4. Your muscles feel tense, tight, or achy
Stiff neck in the morning. Tight shoulders.
Random twitches. Jaw tension.
Magnesium is involved in how muscles relax — so when levels drop, tightness becomes more common.
5. You feel mentally foggy or less patient
Women often describe this as:
- “I’m not the same woman I used to be.”
- “I feel dimmer.”
- “Everything overwhelms me faster.”
Emotional burnout + magnesium depletion creates this “slowed-down” feeling.
6. Your PMS or perimenopause symptoms feel stronger
Magnesium plays a supportive role in mood, tension, and irritability.
When levels are low, monthly symptoms can feel amplified — even if nothing else in your routine changed.
This is one reason so many women 40+ think they’re “just getting older” when it’s often deeper nutrient depletion.
7. Women Over 40 Lose More Magnesium
Cumulative stress:
Your body uses magnesium to calm the nervous system.
The more stress you deal with, the faster you burn through it.
Hormonal changes:
Perimenopause, PMS, sleep shifts — all increase magnesium needs.
Modern diets:
Most diets today have minimal magnesium, far less than what you need.
Here’s the part nobody tells you:
Magnesium comes in different forms and store bought magnesium is the cheapest one: magnesium oxide.
Oxide is cheap, absorbs poorly, and gives little of the benefits you actually need.
So you try it, feel nothing, assume it doesn't work and give up.
You're missing out on all the benefits that could....
That's where Numi comes in. Formulated with 12 active magnesium types:
Magnesium glycinate → deeper sleep and calm
Magnesium malate → energy and fatigue support
Magnesium citrate → digestion and regularity

And 8 other forms for replenishment and better absorption.
