Can we please stop trying to lower a hormone your body desperately needs?
There is a new villain on TikTok.
Apparently, it’s cortisol.
Feeling tired? Cortisol.
Can’t lose weight? Cortisol.
Waking up at 3 a.m.? Cortisol.
Have a little belly? CORTISOL.
Stressed about your cortisol? Better buy the supplement that lowers your cortisol.
And if you happen to wake up in the morning with a perfectly normal, physiologically appropriate rise in cortisol?
Congratulations.
You’re a mammal.
We need to talk.
Cortisol is not the bad guy.
Cortisol is a steroid hormone produced by your adrenal glands. And despite its current reputation as the hormonal equivalent of a toxic ex-boyfriend, cortisol is absolutely essential to keeping you alive.
It helps regulate:
- Blood glucose
- Blood pressure
- Metabolism
- Immune and inflammatory responses
- Energy availability
- Your response to physical stress
- Alertness and wakefulness
Without enough cortisol, you can become seriously ill.
So why does everyone suddenly want to “lower” it?
Because “lower your cortisol” sounds a hell of a lot more marketable than “your endocrine system is complicated.”
HERE’S THE PART TIKTOK LEFT OUT
Cortisol is supposed to have a rhythm.
Your adrenal glands don’t just dump cortisol into your bloodstream at random.
Normally, cortisol begins rising during the latter part of the night and reaches its highest levels in the early morning—generally around the time you wake up.
Then it gradually declines throughout the day, reaching its lowest levels around midnight.
That’s normal physiology.
So when someone tells you:
“Your cortisol is highest in the morning! That’s why you can’t lose weight!”
I have a question.
Compared with what?
Because that’s exactly what your cortisol is supposed to be doing.
Trying to eliminate the normal morning cortisol surge is like trying to eliminate your morning coffee by murdering the coffee plant.
Wrong target.
WHEN CORTISOL REALLY IS A PROBLEM
There absolutely are situations where cortisol is pathologically elevated.
One of them is Cushing syndrome.
And Cushing syndrome is not some vague condition where you feel a little stressed and carry extra weight around your middle.
It is a real endocrine disorder involving prolonged exposure to excessive cortisol.
People with Cushing syndrome can develop findings such as:
- Progressive central weight gain
- Facial rounding
- Easy bruising
- Thin skin
- Wide, violaceous stretch marks
- Proximal muscle weakness
- Hypertension
- Glucose intolerance or diabetes
- Osteoporosis
- Menstrual abnormalities
- Mood and cognitive changes
And here’s something important:
The problem isn’t simply “high cortisol.”
One of the important abnormalities in Cushing syndrome is disruption of the normal cortisol rhythm.
Someone with Cushing syndrome may have cortisol that remains abnormally elevated at night—when it should be very low.
That distinction matters.
Because a single cortisol number does not tell you the whole story.
YOUR 8 A.M. CORTISOL IS NOT SUPPOSED TO LOOK LIKE MIDNIGHT CORTISOL
This seems obvious.
But apparently we need to say it.
If you measure cortisol at 8 a.m. and it’s higher than it would be at midnight, that is not automatically a problem.
It’s supposed to be.
The endocrine system is rhythmic.
We don’t diagnose endocrine disease by taking one random number, declaring it “high,” and then selling you a bottle of capsules.
At least, we shouldn’t.
When Cushing syndrome is actually suspected, clinicians use validated testing designed to assess inappropriate cortisol production or loss of normal regulation.
That may include:
- Late-night salivary cortisol
- 24-hour urinary free cortisol
- A 1-mg overnight dexamethasone suppression test
That’s medicine.
“Take these cortisol-balancing gummies because you have a cortisol belly” is marketing.
AND WHAT THE HELL IS A “CORTISOL BELLY”?
This one deserves its own paragraph.
“Cortisol belly” is not a medical diagnosis.
Abdominal adiposity is real.
Insulin resistance is real.
Menopause-related changes in body composition are real.
Sleep deprivation is real.
Chronic stress is real.
Cushing syndrome is real.
But slapping the word cortisol onto abdominal fat does not magically establish the cause.
Human metabolism is not a one-hormone vending machine.
Weight and body composition are influenced by genetics, age, sex hormones, insulin sensitivity, energy intake and expenditure, sleep, physical activity, medications, medical conditions, and a whole host of other factors.
Could chronic stress contribute to metabolic changes?
Absolutely.
Does that mean every woman with abdominal fat needs a cortisol-lowering supplement?
Absolutely fucking not.
BUT I’M STRESSED. DOESN’T THAT RAISE CORTISOL?
Yes.
And that’s not necessarily bad either.
Your body is designed to respond to stress.
You exercise → cortisol can rise.
You wake up → cortisol rises.
You get sick → cortisol rises.
You have an acute physical stressor → cortisol rises.
Your body needs to mobilize energy and resources when something demands them.
The goal isn’t to live in a state of permanently suppressed cortisol.
The goal is appropriate regulation.
There’s a massive difference between:
“My body mounted an appropriate stress response.”
and
“I have pathological hypercortisolism.”
Those are not remotely the same thing.
SO WHAT ABOUT ALL THOSE “CORTISOL SUPPORT” SUPPLEMENTS?
Here’s where I get cranky.
Because the marketing often sounds incredibly scientific.
“Balances cortisol.”
“Supports healthy cortisol levels.”
“Lowers stress hormones.”
“Helps eliminate cortisol belly.”
“Resets your adrenal glands.”
Sounds impressive.
But here’s the question nobody asks:
What was your cortisol before you took it?
And more importantly:
What problem are we trying to treat?
If someone has documented Cushing syndrome, they need an appropriate endocrine evaluation and treatment.
If someone has normal cortisol physiology but is exhausted, sleeping poorly, gaining weight, feeling anxious, or overwhelmed?
Let’s figure out why.
Maybe they’re not sleeping.
Maybe they’re in menopause.
Maybe they’re under-eating.
Maybe they’re overtraining.
Maybe they’re drinking too much alcohol.
Maybe they’re dealing with depression or anxiety.
Maybe they’re working 60 hours a week.
Maybe they have sleep apnea.
Maybe they’re taking a medication that is affecting them.
Maybe their thyroid function needs evaluation.
Maybe they’re simply exhausted because modern life is fucking exhausting.
Those problems deserve actual attention.
Not a magical “cortisol detox.”
LOWER IS NOT ALWAYS BETTER
This is the part of the supplement industry that drives me absolutely insane.
We’ve somehow decided that every biomarker should be pushed downward.
Cholesterol? Lower.
Glucose? Lower.
Insulin? Lower.
Cortisol? LOWER!
Except biology doesn’t work that way.
There is usually an optimal range and an appropriate physiologic context.
Too little cortisol can be dangerous.
Too much cortisol can be dangerous.
Normal cortisol is not dangerous.
The goal is not to have the lowest cortisol possible.
The goal is to have a properly functioning hypothalamic-pituitary-adrenal axis responding appropriately to the demands placed on your body.
That’s a considerably less sexy marketing slogan.
But it’s science.
AND YES, WOMEN ARE PARTICULARLY VULNERABLE TO THIS SHIT
Because women are already bombarded with messages telling us our bodies are malfunctioning.
Your hormones are “imbalanced.”
Your metabolism is “broken.”
Your estrogen is “toxic.”
Your thyroid is “sluggish.”
Your adrenals are “fatigued.”
Your cortisol is “too high.”
And conveniently, someone has a supplement, powder, tea, tincture, gummy, or $97 monthly subscription that will supposedly fix it.
Your body is not a collection of defective parts waiting for the right supplement.
Sometimes there is a disease.
Sometimes there is a deficiency.
Sometimes there is a hormone disorder.
And sometimes your body is doing exactly what it’s supposed to do.
The trick is knowing the difference.
SO WHAT SHOULD YOU DO ABOUT CORTISOL?
Start with the boring stuff.
The stuff that doesn’t come in a cute little jar.
Sleep.
Move your body.
Eat enough nutritious food.
Get adequate protein.
Don’t chronically overtrain.
Address excessive alcohol use.
Manage chronic stress where you can.
Treat actual medical conditions.
And if you have symptoms that genuinely suggest pathological cortisol excess?
Get evaluated.
Not TikTok-evaluated.
Not supplement-store-evaluated.
Clinically evaluated.
THE BOTTOM LINE
Cortisol has had one hell of a PR problem.
It’s been turned from an essential hormone into a villain because “lower your cortisol” is an extraordinarily convenient thing to sell.
But cortisol isn’t the enemy.
Dysregulated cortisol can be a problem. Cushing syndrome is a real disease.
But a normal morning cortisol rise?
That’s your body doing its job.
So the next time somebody tells you that you need to “lower your cortisol,” ask them a very annoying question:
“Why?”
What is your cortisol actually doing?
What is the evidence that it’s abnormal?
What condition are we treating?
What outcome are we trying to improve?
And what happens if we suppress a hormone your body actually needs?
Because lower isn’t automatically healthier.
And your hormones don’t need to be bullied into submission just because somebody on TikTok figured out how to put the word cortisol on a supplement bottle.
Welcome to Essential Rebellion.
We don’t hate hormones.
We hate lazy explanations.
We hate turning complicated physiology into a sales pitch.
And we’re damn sure not going to let TikTok diagnose your endocrine system.
Ask why.
That’s where the interesting stuff starts.
