🩸 Iron, Ferritin & Hormones: The Midlife Energy Triangle Nobody Warned You About

🩸 Iron, Ferritin & Hormones: The Midlife Energy Triangle Nobody Warned You About

🌸 Is It Your Hormones, Your Iron… or Both?

You are exhausted.

Not “I stayed up too late scrolling” exhausted.

I mean the kind of tired where your body wakes up at 30% battery and somehow expects you to run meetings, answer emails, exercise, cook dinner and still remember why you walked into the kitchen.

Then your hair starts shedding.

Your concentration disappears.

You feel cold.

Your workouts suddenly feel harder.

Maybe there are headaches, restless legs, breathlessness or heart palpitations.

And because you are somewhere in the wonderfully unpredictable world of perimenopause, everyone immediately points at your hormones.

And yes—your hormones may absolutely be involved.

But so might low iron and low ferritin.

And sometimes the answer is:

Both.

Heavy menstrual bleeding is a recognised cause of iron deficiency, and perimenopause can bring significant changes in bleeding patterns.

So before we throw every symptom into the “just menopause” basket, we need to understand another important midlife relationship:

Hormones + iron + ferritin.

Because your body is not malfunctioning randomly.

It is communicating.

And those symptoms may be giving us valuable healing opportunities.

🧬 First Things First: Iron and Ferritin Are NOT the Same Thing

This distinction causes plenty of confusion.

🩸 Iron

Iron is an essential mineral your body uses to make haemoglobin, the protein inside red blood cells that transports oxygen.

Iron also contributes to energy production, neurological function and numerous enzyme systems.

Think of iron as the cargo your body needs delivered.

🚚 Transferrin

Transferrin is one of the proteins that transports iron through the bloodstream.

Transferrin saturation, or TSAT, helps tell us how much of that transport capacity is actually carrying iron.

🏦 Ferritin

Ferritin is primarily an iron-storage protein.

Think of ferritin as your iron savings account.

You can therefore have haemoglobin that has not yet dropped into an anaemic range while your iron reserves are already becoming depleted.

That is why someone may experience iron-related symptoms before developing full iron-deficiency anaemia.

But ferritin comes with a plot twist.

Ferritin is also affected by inflammation and infection. It can rise when the immune system is activated, meaning a normal or elevated ferritin does not always guarantee that iron is readily available to the body. WHO recommends interpreting ferritin alongside the inflammatory picture when inflammation or infection is present.

Which brings us to one of my favourite sayings:

Never marry one laboratory marker.

We look at the whole pattern. 😏

---

🚦 Meet Hepcidin: Your Iron Traffic Controller

Now we need to talk about a fascinating little hormone called hepcidin.

Hepcidin is produced primarily by the liver and plays a major role in regulating how much iron enters and circulates through your bloodstream.

When hepcidin rises, it reduces the activity of ferroportin, the protein that helps move iron out of intestinal cells and storage cells into circulation.

In simple English:

Higher hepcidin:

🚫 “Hold the iron.”

Lower hepcidin:

✅ “Release the iron.”

Chronic inflammation can raise hepcidin, making iron less available even when stored iron is present. This is sometimes called functional iron deficiency or iron restriction.

And yes…

Your reproductive hormones interact with this system too.

---

🎢 Estrogen, Progesterone & Iron: Midlife Gets Interesting

Estradiol appears to influence iron regulation partly through its relationship with hepcidin.

Human research has demonstrated reductions in circulating hepcidin when endogenous estrogen rises substantially, which provides one potential mechanism connecting reproductive hormones and iron availability.

But—and this is important—the relationship between ovarian hormones and iron is more complicated than:

“Estrogen good for iron. Progesterone bad for iron.”

The menstrual cycle affects iron physiology through several overlapping mechanisms, including hormonal fluctuations, hepcidin regulation and—most importantly—actual menstrual blood loss.

So I would not start timing your entire iron strategy around your luteal phase because somebody made a colourful Instagram graphic about progesterone. 😏

Perimenopause adds even more variability because ovulation may become inconsistent and estrogen and progesterone patterns become less predictable.

Then comes the really important piece…

---

🩸 The Perimenopause Iron Drain: Heavy Bleeding

For many women, the strongest relationship between perimenopause and low iron has nothing mysterious about it.

She is losing blood.

During the menopause transition, cycles may become:

• heavier

• longer

• shorter

• closer together

• more unpredictable

• occasionally prolonged

Conditions such as uterine fibroids, adenomyosis and endometrial polyps can also contribute to heavy menstrual bleeding.

And blood contains iron.

If you repeatedly lose more iron than you are replacing, ferritin can gradually drop.

NICE recommends assessing women with heavy menstrual bleeding according to their bleeding pattern, symptoms and possible underlying uterine causes.

This is why simply telling a woman with heavy periods to:

“Take some iron.”

may only address half the problem.

If the drain is open, we need to find out why.

---

🕵🏾‍♀️ Low Iron & Low Ferritin: What Else Could Be Behind It?

Heavy periods are common.

They are not the only cause.

When ferritin repeatedly drops despite supplementation or an iron-rich diet, I want to widen the investigation.

🩸 Chronic Blood Loss

Iron can be lost through:

• heavy menstrual bleeding

• gastrointestinal bleeding

• stomach or intestinal ulcers

• inflammatory bowel disease

• haemorrhoids

• some gastrointestinal conditions

• frequent blood donation

• surgery or significant previous blood loss

After menopause, unexplained iron-deficiency anaemia becomes particularly important to investigate because monthly menstrual blood loss is no longer the obvious explanation.

🥗 Not Getting Enough Iron

Low intake may occur with:

• chronic dieting

• under-eating

• poor appetite

• very restrictive eating patterns

• limited food variety

• poorly planned plant-based diets

A well-planned whole-food, plant-based diet can absolutely provide iron.

But simply being plant-based does not automatically make the diet nutritionally complete.

Plant-forward needs to be plant-smart.

🌾 Poor Absorption

Sometimes there is enough iron coming in.

The gut simply is not absorbing it well.

Potential contributors include:

• coeliac disease

• inflammatory bowel disease

• intestinal disease

• previous gastrointestinal or bariatric surgery

• reduced stomach acidity

• certain long-term medications

Gastroenterology guidelines specifically recognise dietary insufficiency, malabsorption and gastrointestinal pathology among causes of iron-deficiency anaemia.

🦠 H. pylori

Helicobacter pylori, a bacterium that colonises the stomach, has also been associated with iron deficiency and iron-deficiency anaemia in some people.

It may influence iron status through chronic gastritis, altered stomach physiology, impaired absorption or gastrointestinal blood loss.

A 2024 study involving women found an association between H. pylori infection and both iron deficiency and iron-deficiency anaemia, although finding H. pylori does not automatically prove that it caused someone's low ferritin.

🪱 Parasitic Infections

And yes—parasites belong on the list when the exposure history and symptoms make sense.

Hookworm is a classic example.

Hookworms attach to the intestinal lining and feed on blood. More substantial infections can produce chronic intestinal blood loss, leading to iron loss and anaemia.

This becomes more relevant when there is a history of travel or residence in endemic areas, exposure to contaminated soil, persistent gastrointestinal symptoms, unexplained eosinophilia or recurrent unexplained iron deficiency.

But low ferritin does not automatically equal parasites.

Please don't see ferritin of 20 and immediately order wormwood, clove and black walnut. 😂

Test, don't guess.

🔥 Chronic Inflammation & Infection

Here is an important distinction:

Inflammation does not necessarily make ferritin low.

It may do the opposite.

Inflammation can increase hepcidin and trap iron inside storage cells while simultaneously pushing ferritin upward.

That means someone can have poor iron availability with ferritin that looks perfectly respectable—or even high.

That is one reason ferritin should never be interpreted alone.

🔬Fun Fact Science Bar+

Did you know iron is needed for more than making red blood cells? Iron also supports dopamine production, because the enzyme involved in making dopamine depends on iron. When iron stores are low, some women may notice more brain fog, reduced concentration, restless legs, low motivation or that frustrating “my brain knows what it wants to do, but apparently nobody told my energy levels” feeling. 🧠🩸

👉🏾 Translation: Midlife fatigue and poor concentration are not automatically “just hormones.” Low ferritin, changing hormones, sleep disruption, thyroid function, stress and nutrient status can overlap and create a lovely little Metabolic Chaos® committee meeting nobody scheduled. 😅

✨ Healing Opportunity: Instead of chasing symptoms, look at the pattern. Consider iron studies alongside B12, folate, thyroid markers, inflammation, diet, menstrual blood loss and digestive health. Nourish with iron-rich foods paired with vitamin C, protect sleep, move appropriately and test before automatically adding iron supplements.

✝️ Faith Element: A clear mind and well-nourished body help us better fulfil the work God has given us. Caring for the brain, blood and nervous system through nourishment, rest, temperance and wise investigation is part of good stewardship. 🌿🙏🏾

😵‍💫 “But Those Symptoms Sound Exactly Like Perimenopause!”

They certainly can.

Iron deficiency may contribute to:

• fatigue

• weakness

• reduced exercise tolerance

• breathlessness

• headaches

• heart palpitations

• hair shedding

• restless legs

• difficulty concentrating

• feeling unusually cold

Several of those overlap beautifully—or rather, annoyingly—with perimenopause.

So imagine a woman experiencing:

Hormonal fluctuations.

Poor sleep.

Heavy menstrual bleeding.

Low ferritin.

Blood-sugar instability.

Stress.

Digestive dysfunction.

And now perhaps thyroid changes too.

One symptom may have several contributing mechanisms.

That is what I call Metabolic Chaos®.

Everyone keeps arguing over which symptom belongs to which box…

while your body is standing there saying:

“Excuse me, we are all connected.”

---

🔄 Then Menopause Changes the Iron Story Again

Here is something women are rarely told.

Once menstruation permanently ends, monthly iron loss stops.

Iron status may subsequently begin moving in the opposite direction.

A 2025 longitudinal study following 1,885 women through natural menopause found increases in ferritin, serum iron and transferrin saturation around the final menstrual period, with ferritin continuing to increase afterward.

That means our concern can gradually shift from:

“Why is she losing so much iron?”

during menstruating perimenopause…

to:

“Why is her ferritin increasing?”

after menopause.

But again:

High ferritin does not automatically mean iron overload.

Ferritin can also rise alongside inflammation, metabolic dysfunction and liver abnormalities. WHO likewise cautions that elevated ferritin requires interpretation in context rather than being treated as a stand-alone measure of iron stores.

So:

Low ferritin deserves investigation.

High ferritin deserves investigation.

And even “normal” ferritin deserves context.

---

🧪 Test, Don't Guess: The Laboratory Puzzle

If a woman is experiencing fatigue, hair shedding, heavy bleeding, restless legs, palpitations or reduced exercise tolerance, the starting point is generally conventional blood chemistry.

Depending on the clinical picture, that may include:

• full blood count/CBC

• haemoglobin

• haematocrit

• MCV

• MCH

• RDW

• ferritin

• serum iron

• transferrin or TIBC

• transferrin saturation

• CRP or other inflammatory markers where appropriate

• vitamin B12

• folate

• thyroid markers

• liver and kidney chemistry

Ferritin is particularly useful for identifying depleted iron stores, but when inflammation is present, additional iron indices become increasingly important.

And then we ask:

What caused the pattern?

This is where targeted functional testing may sometimes add useful context.

---

🔬 Where Functional Testing Can Fit

Functional testing should complement good clinical assessment—not replace it.

🧬 DUTCH

DUTCH can provide information about sex hormones and their metabolites as well as cortisol and related adrenal hormone patterns.

It does not diagnose iron deficiency, but it may help us understand the hormonal terrain surrounding symptoms such as menstrual changes, poor sleep, stress or other midlife complaints.

🧬 DNAlife Hormones & DNA Mind

Genetic testing such as DNAlife Hormones and DNA Mind can provide another layer of information about inherited tendencies involving hormone metabolism and neurological or nutrient-related pathways.

But genes are tendencies.

They are not current hormone levels.

And they are certainly not your destiny.

🩸 Functional Blood Chemistry Analysis — FBCA

This is where looking at conventional blood work as a pattern can become particularly useful.

Instead of staring at ferritin by itself, we can consider iron indices alongside:

• red-cell markers

• thyroid patterns

• glucose regulation

• inflammation

• liver function

• nutrient status

Now we are looking at the orchestra rather than blaming the flute. 🎻

🦠 GI-MAP

When persistent bloating, altered bowel movements, digestive complaints or suspected gastrointestinal contributors are part of the picture, GI-MAP may provide additional information about selected organisms, including H. pylori, bacteria and certain parasites, as well as digestive and inflammatory markers.

However, no single stool panel identifies every possible parasite or gastrointestinal disease.

When a true infection, bleeding disorder, coeliac disease or other pathology is suspected, conventional medical testing may still be needed.

🍽️ MRT

In selected cases, MRT may form part of a structured nutrition strategy when food-related symptoms are being investigated.

But MRT does not diagnose iron deficiency and should never become an explanation for low ferritin without investigating the established causes first.

That is the difference between:

Testing everything because we can

and

Testing strategically because we have a question.

That is test, don't guess.

---

🌸 And About Hormone Testing During Perimenopause…

Here is another important distinction.

Women over 45 do not usually need standard hormone blood testing simply to prove that they are in perimenopause.

Current NICE guidance recommends identifying perimenopause in otherwise healthy women aged 45 or older primarily through symptoms and menstrual-cycle changes rather than routinely using tests such as estradiol to diagnose the transition.

That does not mean laboratory information is useless.

It means we ask:

What clinical question are we trying to answer?

Hormone testing for additional context?

Iron testing for suspected deficiency?

GI testing for digestive complaints?

Blood chemistry to investigate fatigue?

Different question.

Different tool.

---

🥗 Feed the Iron Factory

Food matters, particularly when rebuilding or protecting iron stores.

For a whole-food, plant-forward approach, regularly include foods such as:

🌱 lentils
🌱 black beans
🌱 chickpeas
🌱 tofu and tempeh
🌱 pumpkin seeds
🌱 sesame and tahini
🌱 quinoa and amaranth
🌱 leafy green vegetables
🌱 iron-fortified foods where appropriate

Pair plant iron with vitamin C-rich foods such as peppers, citrus, kiwi, berries, tomatoes or broccoli to help improve non-haem iron absorption.

Tea and coffee can reduce iron absorption when taken close to iron-rich meals or supplements, so timing may matter when someone is actively trying to rebuild depleted stores.

And remember:

If you are bleeding heavily or failing to absorb iron, no amount of spinach deserves responsibility for fixing the entire situation.

Food supports the body.

Root causes still matter.

---

🏋🏾‍♀️ Exercise: Strong, Not Depleted

Movement is still one of our greatest midlife allies.

Think:

💪🏾 resistance training
🚶🏾‍♀️ walking
❤️ appropriate cardiovascular exercise
🤸🏾‍♀️ mobility and recovery work

But exercise should match the woman standing in front of us.

If you suddenly cannot complete workouts that previously felt manageable, your heart rate feels unusually high, you are breathless, dizzy or profoundly fatigued, that deserves investigation.

The answer is not always:

“Push harder.”

Sometimes the body is asking:

“Could we perhaps have some oxygen first?” 😏

---

😴 Sleep: Your Body Does Repair Work Here

Sleep will not magically increase ferritin.

But inadequate sleep can amplify many symptoms that already overlap with iron deficiency and perimenopause:

• fatigue

• brain fog

• irritability

• cravings

• poor recovery

• anxiety

• difficulty regulating appetite

Protect your evening routine.

Get daylight in the morning.

Allow time for rest.

Keep your room cool and dark.

Meditate on Scripture or read something calming rather than giving your nervous system another three hours of doom-scrolling.

Midlife is not the season to brag about functioning on four hours of sleep.

Your nervous system would like to unsubscribe.

---

💊 Supplements: Please Don't Throw Iron at Every Tired Woman

Iron supplementation can be extremely useful when iron deficiency is established.

But iron is not a casual “just in case” supplement.

The appropriate form, amount and duration depend on:

• your laboratory results

• severity of deficiency

• menstrual blood loss

• absorption

• gastrointestinal tolerance

• medications

• medical history

• why the deficiency developed

Some women tolerate forms such as iron bisglycinate better than traditional iron salts, while others may require different approaches.

Vitamin C-rich foods can help support non-haem iron absorption.

And depending on testing, nutrients such as B12, folate, vitamin D or magnesium may need individual attention—but they cannot substitute for treating genuine iron deficiency.

Most importantly:

Do not keep increasing iron indefinitely because ferritin refuses to stay up.

That is when the question changes from:

“How much more iron do I need?”

to:

“Why am I not keeping it?”

There may be another healing opportunity hiding underneath the number.

🚫 Three Midlife Iron Myths We Can Retire

❌ “My haemoglobin is normal, so my iron must be fine.”

Not necessarily.

Iron stores can become depleted before anaemia develops.

❌ “My ferritin is high, so I definitely have plenty of available iron.”

Not necessarily.

Inflammation and infection can raise ferritin and alter iron availability.

❌ “I'm in perimenopause, so all these symptoms are hormonal.”

Maybe some are.

But menopause does not receive custody of every symptom after age 40. 😂

---

🚨 When the Bigger Picture Needs Medical Investigation

Some patterns should not simply be managed nutritionally.

These include:

• very heavy or prolonged menstrual bleeding

• new bleeding after menopause

• recurrent or unexplained iron-deficiency anaemia

• black or bloody stools

• significant breathlessness

• fainting

• chest pain

• rapidly worsening palpitations

• unexplained weight loss

• persistent vomiting

• significant or persistent gastrointestinal symptoms

In particular, unexplained iron-deficiency anaemia after menopause deserves investigation because gastrointestinal blood loss and gastrointestinal disease become important considerations.

Root-cause care includes knowing when another professional needs to join the team.

🌿 From Metabolic Chaos® to Healing Opportunities

This is the part of functional health that I love.

Your body is not a collection of unrelated organs.

Your gut influences nutrient absorption.

Your liver produces hepcidin.

Your blood transports oxygen.

Your ovaries produce hormones.

Your thyroid influences metabolism.

Your nervous system influences sleep and stress.

Your nutritional status influences all of them.

So one woman may have:

heavy bleeding → depleted ferritin → fatigue

while another has:

gut dysfunction → poor absorption → low iron

another:

inflammation → elevated hepcidin → poor iron availability

and another:

perimenopause + low iron + poor sleep + blood-sugar instability

Same complaint.

Different pattern.

Different healing opportunities.

That is why personalised naturopathy and functional nutrition should never be:

“You are tired? Take these twelve supplements.”

We investigate.

We connect the dots.

We support what actually needs supporting.

---

✝️ Midlife Is a New Chapter—Not the Last Chapter

Perimenopause can make you wonder when your body changed the passwords without telling you.

But this transition is not the end of your vitality, femininity, usefulness or purpose.

It is a new season.

And new seasons sometimes require a different way of caring for ourselves.

There is beautiful wisdom in many of the foundational principles that have long been part of the Adventist health message:

🌱 nourishing food
🚶🏾‍♀️ movement
☀️ appropriate sunlight
💧 hydration
🌿 temperance
😴 restorative rest
🙏🏾 trust in God

Simple does not mean insignificant.

And science continues to show us how beautifully interconnected the systems of the human body really are.

You are not finished because your hormones are changing.

Your body may simply require different support than it did at 25.

There is still strength to build.

Health to steward.

Wisdom to gain.

Purpose to fulfil.

And plenty of life left in this chapter. 🌸
