Quick Answer: Iron deficiency is one of the most common nutritional gaps in women, largely due to menstrual blood loss, and has been associated with reduced immune cell function. Addressing a genuine deficiency — confirmed by a blood test — is important for both energy and immune health.

Why Iron Deficiency Is So Common in Women
Regular menstrual blood loss means women generally require more dietary iron than men. Pregnancy, heavy periods, and certain dietary patterns (particularly vegetarian and vegan diets, where iron is less easily absorbed) can further increase the risk of deficiency.
The Iron-Immunity Link
Iron is required for the normal function and development of several types of immune cells. Deficiency has been associated with reduced immune responsiveness, on top of its more widely known effects on energy and cognitive function.
Signs to Watch For
- Persistent fatigue
- Pale skin
- Shortness of breath during normal activity
- Frequent minor illnesses
- Brittle nails or hair changes
These symptoms overlap with many other conditions, so a blood test is the only reliable way to confirm iron deficiency rather than self-diagnosing from symptoms alone.
Getting Tested and Treated
A simple blood test through your GP can confirm iron levels and ferritin (iron stores). Treatment typically depends on severity — ranging from dietary changes to supplementation, with your doctor guiding the appropriate dose and duration.
Dietary Sources of Iron
Red meat, poultry and fish provide readily absorbed haem iron. Plant sources like legumes, tofu and leafy greens provide non-haem iron, which is less easily absorbed but can be improved by pairing with Vitamin C-rich foods.
Where Nature's Help Fits In
If a blood test confirms a genuine iron gap, our iron formula is designed to support healthy iron levels as part of a broader nutritional approach — always used alongside your doctor's guidance rather than as a substitute for testing.
FAQs
Why are women more prone to iron deficiency?
Regular menstrual blood loss increases iron requirements, and pregnancy or heavy periods can further increase the risk.
Can low iron affect my immune system?
Yes, iron is needed for normal immune cell function, and deficiency has been associated with reduced immune responsiveness.
How do I know if I'm iron deficient?
A blood test through your GP is the only reliable way to confirm iron deficiency — symptoms alone can overlap with many other conditions.
Should I take iron supplements without testing first?
It's best to confirm a genuine deficiency with a blood test before supplementing, as excess iron can also cause health issues.
What foods help improve iron absorption?
Pairing plant-based (non-haem) iron sources with Vitamin C-rich foods, like citrus, can help improve absorption.
Our Simple Recommendation
If you're feeling persistently run down, get your iron levels checked before assuming or self-treating. A confirmed deficiency is easily addressed with the right guidance from your doctor.
