How common is iron deficiency in women, really?

More common than most women realize: a 2025 national analysis found that roughly 27% of non-pregnant, reproductive-age women in the United States have iron deficiency, and a 2025 review notes this is one of the most consistent sex-based health disparities in adult medicine, driven largely by monthly menstrual blood loss. Because the symptoms, fatigue, brain fog, feeling "just tired all the time", are easy to attribute to a busy schedule or poor sleep, iron deficiency without full anemia often goes unrecognized.

Always consult your healthcare provider before starting any new supplement, especially during pregnancy, breastfeeding, or while managing a medical condition.

Why this is so under-recognized

Part of the issue is screening. According to a 2025 review of sex- and gender-based inequities in iron deficiency, there's no formal consensus on routine iron deficiency screening for asymptomatic, non-anemic reproductive-age women in the United States, even though this group is known to carry a disproportionate share of the burden due to menstrual blood loss. In other words, unless you happen to get a ferritin test, iron deficiency without anemia can go unnoticed for a long time, even while it's affecting how you feel day to day.

"I think so many things can be avoided if there's just prevention."

— Dr. Samantha Ess, ND, Naturopathic Doctor specializing in hormone health and fertility

Dr. Ess's point is exactly the gap here. Iron deficiency is preventable and correctable, but only if it's identified. The NIH's Office of Dietary Supplements notes that even iron deficiency without anemia is associated with fatigue and reduced cognitive and physical performance, which means the "I'm just tired" feeling many women write off may have an identifiable, addressable cause.

What to do with this information

If fatigue, brain fog, or a general sense of running low has been a persistent pattern, ask your healthcare provider about checking ferritin and hemoglobin levels rather than assuming it's unavoidable. On the nutrition side, our prenatal with methylated folate and gentle iron is formulated with iron bisglycinate chelate, a form intended to be gentler on digestion than standard ferrous sulfate, to support healthy iron status.†

Amy has spoken about wanting women to feel equipped, not just told to push through. Total Prenatal, designed for preconception through breastfeeding, is third-party tested at ISO 17025 accredited labs and manufactured in cGMP-certified facilities, part of the standard behind Pink Stork's 50,000+ verified Amazon reviews.

Frequently asked questions

How many women actually have iron deficiency?

A 2025 national analysis found that roughly 27% of non-pregnant, reproductive-age women in the U.S. have iron deficiency, primarily linked to menstrual blood loss.

Why doesn't my doctor automatically test for this?

There's currently no formal U.S. consensus recommending routine iron deficiency screening for asymptomatic, non-anemic reproductive-age women, so it isn't always tested unless you ask or have symptoms flagged.

What are signs of iron deficiency without full anemia?

Fatigue and reduced cognitive or physical performance have been linked to iron deficiency even before it progresses to anemia. A blood test measuring ferritin is the most direct way to check.

Why does Total Prenatal use a different form of iron?

It uses iron bisglycinate chelate (Ferrochel), formulated to be gentler on digestion than standard ferrous sulfate, which can cause constipation in some people.†

Is iron deficiency only a concern for women trying to conceive?

No. It's primarily driven by monthly menstrual blood loss, which affects any menstruating woman regardless of pregnancy plans.
