If you’re wondering “Should I take melatonin” read this…
Most of the time?
Melatonin isn’t the real issue.
It’s not that it’s “bad.”
It’s that it’s rarely the root cause of why you’re not sleeping.
In fact, I can count on one hand the number of times I’ve included melatonin in a client’s plan.
Before you add it in, increase the dose, or add another sleep gummy to the lineup, let’s talk about what melatonin actually does — and what it doesn’t.
What Melatonin Actually Does
Melatonin is a hormone.
Its job is simple:
It signals darkness.
That’s it.
When light goes down, melatonin rises.
It tells your brain, “It’s nighttime. Time to sleep.”
It does not:
Override high cortisol
Stabilize blood sugar
Fix progesterone drops
Calm a wired nervous system
If your body is in stress mode, melatonin can’t force it into sleep.
Which brings me to a story.
Years ago, during early labor, a hospital nurse offered me Ambien thinking it would stop contractions.
You can probably guess how that went.
If the body is in a process — whether that’s labor or stress physiology — sedating it doesn’t stop the process.
It just misses the point.
Melatonin works the same way.
Why Melatonin Doesn’t Work for Many Women
When someone says, “Melatonin doesn’t work for me,” I don’t think:
“Let’s increase the dose.”
I ask:
Why is your body still on?
Here are the most common reasons melatonin fails.
1. Cortisol Is Still High at Night
Cortisol and melatonin are opposites.
Cortisol should gradually decline throughout the day so melatonin can rise at night.
If cortisol is still elevated at 9pm… 10pm… 11pm…
Melatonin literally cannot dominate.
Common contributors:
Working late under bright light
Scrolling in bed
Intense TV right before sleep
Chronic stress
Overtraining
Undereating
Hormones run on patterns.
If you repeatedly stimulate your nervous system at night, your body adapts to expect it.
And it will keep producing cortisol accordingly.
No supplement overrides a pattern you rehearse daily.
2. Blood Sugar Is Dropping Overnight
If you fall asleep fine but wake up wired in the middle of the night, melatonin isn’t your fix.
Stabilizing your blood sugar often is.
When glucose drops too low overnight, the body releases adrenaline and cortisol to raise it.
Adrenaline wakes you up.
Melatonin can’t compete with adrenaline.
That’s not a dosing issue.
That’s physiology.
3. Progesterone Is Declining
Especially in early perimenopause.
Progesterone supports GABA — your calming neurotransmitter.
When progesterone drops, GABA often drops too.
Which looks like:
Tired but wired
Waking at every sound
Nighttime anxiety
Light, fragile sleep
You can add melatonin…
But if progesterone and GABA support are low, the system is still unstable.
4. You’re Trying to Sedate a Nervous System That Doesn’t Feel Safe
This is the piece most people miss.
Sleep is not something you force.
It’s something your body allows.
If your nervous system is in subtle survival mode — jaw tight, shoulders up, breath shallow — melatonin doesn’t fix that.
The body won’t fully rest if it doesn’t feel safe.
When Is Melatonin Helpful?
Melatonin can be useful for:
Jet lag
Shift work transitions
Short-term circadian rhythm resets
Delayed sleep phase
It can also be helpful in low doses for certain individuals under practitioner guidance.
But it’s not a long-term solution for chronic insomnia driven by stress, hormones, or blood sugar instability.
Is Melatonin Safe?
Melatonin is generally considered safe short-term.
However, potential side effects can include:
Morning grogginess
Vivid dreams
Headaches
Hormonal disruption at high doses
More isn’t better.
And more importantly:
Correcting the signal isn’t the same as correcting the system.
The Better Question to Ask
Instead of:
“How much melatonin should I take?”
Ask:
Why is my body not winding down naturally?
Is it:
Light exposure?
Cortisol rhythm?
Blood sugar?
Hormone shifts?
Nervous system tone?
When we identify the bucket, address what’s getting in the way, and create the conditions, sleep inevitably improves.
Not because we forced it.
Because the body finally feels supported and safe enough to rest.
My Approach to Fixing Sleep
When I work with clients, we start with separation.
Are you struggling with:
Falling asleep?
Staying asleep?
Or early morning waking?
They’re different problems.
They have different drivers.
They require different strategies.
We look at:
Morning light exposure
Evening light hygiene
Stress patterns
Nutrient status
Hormone shifts
Blood sugar stability
And then we adjust upstream.
I’ve seen it over and over:
When sleep improves, everything improves.
Energy.
Mood.
Cravings.
Hormones.
Resilience.
We stabilize the foundation before repainting the walls.
Frequently Asked Questions About Melatonin
Should I take melatonin for insomnia?
Melatonin can help regulate circadian rhythm, but it does not address stress hormones, blood sugar instability, or hormone imbalance — which are common drivers of insomnia.
Why doesn’t melatonin keep me asleep?
If you’re waking during the night, cortisol spikes or blood sugar dips are often involved. Melatonin does not override adrenaline.
Is it bad to take melatonin every night?
Short-term use is generally considered safe, but long-term reliance without addressing root causes may delay proper treatment of underlying issues.
What’s a natural alternative to melatonin?
Instead of replacing melatonin, focus on:
Morning sunlight exposure
Evening light reduction
Stable blood sugar
Nervous system regulation
Supporting progesterone and GABA when appropriate
Ready to Go Deeper?
If you’re reading this thinking, “Okay… this is me,”
Your next step is identifying which bucket your sleep issue falls in — is it falling asleep? staying asleep? or light or not restful sleep?
Then we identify the right levers.
And once you do, sleep stops feeling like a battle.
If you’re ready to stop guessing and finally figure out what’s keeping you up at night…
