Chronically Low Iron in Women: Why It Keeps Happening (and Why You Need to Investigate the Cause)
Feeling tired all the time, dizzy when you stand up, short of breath, or like your brain is running in slow motion?
For many women, chronically low iron is brushed off as “just being a bit low” and treated with a basic supplement.
But if your iron keeps dropping, or never properly improves, there is always a reason.
As a Women’s Health Naturopath, I see this pattern often. Iron deficiency is not just about taking more iron. It is about understanding why your levels are low in the first place.
Why iron is so important
Iron is essential for:
Energy production
Oxygen transport in the blood
Cognitive function and concentration
Mood regulation
Healthy hair, skin, and nails
Exercise tolerance and recovery
When iron is low, everything can feel harder than it should.
Common symptoms of low iron
You may experience:
Fatigue that does not improve with rest
Brain fog or poor concentration
Dizziness or light-headedness
Shortness of breath on exertion
Cold hands and feet
Hair shedding or thinning
Restless legs
Low mood or irritability
Why iron keeps dropping (the root causes)
If iron is chronically low, it is important to investigate why.
1. Heavy or painful periods
One of the most common causes in women.
This may include:
Heavy menstrual bleeding
Endometriosis or adenomyosis
Fibroids or hormonal imbalance
Long or frequent cycles with significant blood loss
If you are losing more blood each month than your body can replace, iron stores will continue to fall.
2. Digestive issues and poor absorption
You may be eating enough iron, but not absorbing it properly.
This can occur with:
Coeliac disease (diagnosed or undiagnosed)
Inflammatory gut conditions
Low stomach acid
IBS or gut dysbiosis
Chronic bloating or digestive discomfort
Iron is absorbed in the gut, so gut health is central to iron status.
3. Inflammation and chronic stress
Inflammation in the body can block iron absorption and affect how iron is used.
Chronic stress can also impact digestion and nutrient absorption, making it harder to restore levels even with supplementation.
4. Poor quality or poorly absorbed supplements
Not all iron supplements are created equal.
Some issues include:
Forms that are poorly absorbed
Doses that are too low or too high
Side effects leading to inconsistent use
Not addressing co-factors needed for absorption (like vitamin C, B vitamins, stomach acid support)
If you have tried iron before and it did not work, it does not necessarily mean iron “does not suit you”.
5. Dietary intake and increased needs
Some women are simply not getting enough iron through diet, particularly if:
Intake of red meat or iron-rich foods is low
You are vegetarian or vegan without adequate planning
You are pregnant, postpartum, or have high physical demands
You have ongoing blood loss or high stress load
A naturopathic approach to low iron
A root cause approach looks beyond just “take iron and retest”.
It may include:
Identifying causes of blood loss (cycle health, endo, hormones)
Investigating gut health and absorption issues
Reviewing full iron studies (not just ferritin)
Supporting stomach acid and digestion if needed
Addressing inflammation and stress load
Choosing the right form and dose of iron
Supporting cofactors like vitamin C, B12, folate, and zinc
The goal is not just to raise a number on a blood test.
It is to restore your energy, clarity, and resilience.
You do not have to stay exhausted
If you keep being told your iron is “a bit low” but nothing changes, it is worth looking deeper.
As a Women’s Health Naturopath, I support women with chronic fatigue, heavy periods, and low iron to uncover and address the root cause so they can actually feel better long term.
