Say your level came back low and you were told to start iron. Two things nobody explains: why low iron makes you feel the way you do, and why the pill you were handed is so hard to take.
Iron is part of how you make dopamine
Most people think of iron as the red blood cell mineral. It is, but it does something else too.
Your body builds dopamine from an amino acid called tyrosine, and the enzyme that does the converting needs iron to work. Low iron, less of that conversion. That matters because dopamine is the motivation and drive chemical.
When dopamine runs low, it tends to look like this
– Flat motivation, everything feels like more effort than it should
– Trouble focusing, thoughts sliding away from you
– Fatigue that sleep doesn’t fix
– Low mood, less enjoyment in things you normally enjoy
– Restless legs at night, one of the most iron-linked symptoms there is
That’s why low iron can feel like more than being tired. It can feel like the lights dimmed.
Then you take the iron and your stomach rebels
Most people get handed ferrous sulfate, usually 325 mg. It’s cheap and it’s everywhere. Only a small part of it actually gets absorbed, and the rest sits in the digestive tract. That leftover iron is what causes the nausea, cramping, and constipation. It’s the reason so many bottles end up in the back of a drawer.
Chelated iron is different. The iron is attached to an amino acid, a tiny protein building block the body recognizes, so more of it gets taken in and less is left behind to irritate the gut. People tend to have an easier time staying on it, and staying on it is the whole point.
The labels look confusing. Chelated iron labels often read something like 29 mg next to a 325 mg tablet, which seems weaker. It isn’t the same measurement. What counts is how much your body absorbs and whether you can keep taking it.
Two things worth asking about
Taking iron every other day may absorb as well as taking it daily, whatever form you use, and it’s usually easier on the stomach. Vitamin C alongside it may help absorption too. Both are worth raising with your health care practitioner.
And if you eat little or no meat, low iron is common. Plant iron is a form the body absorbs far less of.
If a gentler option is what you’re after, we carry Iron Glycinate in the IMH shop, a chelated form chosen for tolerability.
