Iron Deficiency & Anemia

Iron deficiency is the most common nutrient deficiency worldwide. Ferritin under 30 ng/mL indicates depleted stores even before anemia; hemoglobin falls later. A cause — blood loss, malabsorption (celiac, H. pylori) or low intake — should always be sought.

Root-cause chain

Each link carries its own evidence grade
  1. Blood loss (menstrual, gastrointestinal)→Depleted iron storesNA

    Each mL of blood lost removes about 0.5 mg of iron.

    Relationship: Established causal

  2. H. pylori or celiac disease→Iron malabsorptionIA

    Mucosal damage and reduced gastric acid impair non-heme iron absorption; eradication or gluten-free diet restores it.

    Relationship: Established causal

  3. Chronic inflammation→Functional iron restriction via hepcidinIA

    IL-6 raises hepcidin, blocking iron export; ferritin may be falsely normal when CRP is high.

    Relationship: Established causal

  4. Iron deficiency→Fatigue, low mood, restless legsBB

    Iron repletion improves fatigue in non-anemic women with low ferritin (RCTs).

    Relationship: Randomized evidence

iDetection of an exposure does not establish that it caused a disease. This platform separates exposure, association, plausible mechanism, clinical evidence and demonstrated causation.

Fifth Estate considerations

Microbial ecology

H. pylori is a true bacterial cause here — test and treat it when iron deficiency is unexplained.

Protocol Fusion Engine

Six lanes · evidence grade and regulatory status on every entry

Conventional

Oral iron on alternate days; IV iron when oral fails or is not toleratedAFDA-approved

Alternate-day dosing improves absorption (Stoffel 2017); AGA 2020 guideline.

Caution: Find the cause; never give iron without testing — risk of overload in hemochromatosis.

Functional

Evaluate gut causes (celiac, H. pylori)ALifestyle

Treating the cause restores absorption.

Caution: Do not start a gluten-free diet before celiac testing.

Integrative

Manage heavy menstrual bleeding with gynecologyAFDA-approved

Most common cause in premenopausal women.

Caution: Evaluate for fibroids and bleeding disorders.

Orthomolecular

Vitamin C with iron-rich mealsCSupplement

Increases non-heme iron absorption.

Caution: Not a substitute for iron repletion.

Traditional

Cooking in cast-iron cookwareCLifestyle

Modest increases in food iron content.

Caution: Not adequate alone for established deficiency.

No energy modality treats iron deficiencyEInvestigational

Caution: Must not be presented as a treatment.

iLanes are presented side by side so the difference in evidence strength is visible. Nothing here is a prescription, and interactions must be reviewed with your clinician and pharmacist.

iEnergy and physical modalities in this lane are explored further with Tayapulse. Evidence grade and regulatory status still apply: these are adjuncts used only where indicated, never cures or replacements for guideline care.

Diagnostics to consider

  • · Ferritin (with CRP)
  • · CBC: hemoglobin, MCV
  • · Transferrin saturation
  • · Celiac serology (tTG-IgA)
  • · H. pylori testing; GI evaluation for men and post-menopausal women

Monitoring

  • · Ferritin and hemoglobin 8–12 weeks after starting iron
  • · Symptom trend
  • · TOBIN score change over time

Prevention emphasis

  • · Heme-iron foods or legumes with vitamin C
  • · Screen in heavy menstrual bleeding and pregnancy
  • · Avoid tea/coffee with iron-rich meals
