Did you know…If you have iron deficiency anemia (IDA) and your numbers aren’t improving…
it may not be the dose.
Iron absorption depends on stomach acid.
When stomach acid is low, iron (especially the non-heme type found in most supplements) may not convert into its absorbable form. That means you can take iron consistently and still struggle to raise ferritin or hemoglobin.
Before automatically increasing your dose, consider:
• Are you taking acid-reducing medications?
• Do you have chronic bloating or digestive symptoms?
• Are you taking iron with coffee, tea, or calcium?
• Are you spacing it correctly from other supplements?
Iron needs:
✔️ An acidic environment
✔️ Proper timing
✔️ The right form
✔️ Adequate vitamin C
Sometimes improving digestion and absorption makes more difference than simply taking more iron.
And if levels still aren’t improving, it’s important to rule out:
• Ongoing blood loss
• Celiac disease
• H. pylori
• Inflammatory conditions
• Heavy menstrual bleeding
Iron deficiency anemia is common — but persistent anemia always deserves a deeper look.
More iron isn’t always the answer.
Better absorption and identifying the root cause is.
