Iron for Menopause

What it is

Iron is a mineral essential for making hemoglobin — the protein in red blood cells that carries oxygen throughout your body. When iron is low, every cell in your body gets less oxygen, which is why the primary symptom of iron deficiency is exhaustion. Iron is especially relevant during perimenopause, when menstrual cycles can become unpredictable and heavier.

How it helps with menopause

Low iron is one of the most common and most overlooked causes of fatigue in women — especially during perimenopause when periods can become heavier and more frequent before stopping altogether. Iron deficiency doesn't just cause tiredness; it can worsen brain fog, mood instability, and even heart palpitations. Many women assume their exhaustion is just part of menopause, when it might be a simple iron deficiency that's easily correctable. Getting your ferritin levels tested is one of the highest-value medical tests during perimenopause.

Dosage & timing

Don't supplement iron without getting your levels checked first — unlike most supplements, too much iron is harmful. If your ferritin is low (below 30ng/mL), your doctor may recommend 25–65mg of elemental iron daily. Take on an empty stomach with vitamin C (which dramatically improves absorption). Don't take iron within 2 hours of calcium, coffee, or tea — they block absorption.

What to look for

Iron bisglycinate (also called iron glycinate) is the gentlest form on the stomach and well-absorbed. Ferrous sulfate is cheaper but commonly causes constipation and nausea. Heme iron supplements (from animal sources) are well-tolerated but more expensive. Always choose a supplement with a clearly stated amount of elemental iron, not just total weight.
