There was a stretch of time when I felt like I was doing everything right—taking the supplement, eating the right foods, staying in rhythm.

And yet… nothing was working.

The symptoms were still there. I was still exhausted. And I started to wonder if supplementation just wasn’t going to work for me at all.

What I didn’t realize was how much more could be going on beneath the surface.

If you’re in that place—doing everything right but still not seeing results—this issue is for you. A few small shifts might be all it takes to help your body actually absorb and use the iron you’re giving it.

Here are some simple, research-backed ways to troubleshoot and start moving forward.

Troubleshooting: What to Do If Your Iron Supplement Still Isn’t Working

Even if you’re taking the right dose at the right time, iron still might not do its job, especially if something else in your body is off balance.

Here are a few of the most common reasons your iron supplement might not be working and what to do about it:

❌ Problem: "I still feel exhausted."

You might be missing other nutrients your body needs to use iron effectively.

• ✅ Check your B12, folate, and magnesium levels. These are essential for energy and iron transport.

• ✅ Consider IV iron. If oral supplements aren’t working, this can bypass absorption issues entirely.

• ✅ Look at your gut health. Inflammation or dysbiosis can block iron absorption altogether.

❌ Problem: "Iron makes me constipated."

Some iron forms, especially ferrous sulfate, are harsh on digestion.

• ✅ Switch to a gentler form, like liquid iron or ferrous bisglycinate.

• ✅ Add magnesium and drink more water. Both can ease constipation.

• ✅ Try alternate-day dosing. This gives your body more time to absorb and reduces side effects.

❌ Problem: "I take iron, but my labs aren’t improving."

Absorption may be the real issue, not dosage.

• ✅ Avoid calcium and coffee. Both block iron absorption if taken around the same time.

• ✅ Try a liquid or sucrosomial iron. Some brands demonstrate better bioavailability than tablets.

• ✅ Get your gut checked. IBS, celiac disease, or other gut imbalances could be the hidden culprit.
