Who it is for

For when your numbers and your days do not add up.

  • Your ferritin is “in range” and you still feel flat.
  • Your periods are heavy, and you want to know what they cost you.
  • You have taken iron for months and your ferritin has barely moved.
  • You eat little or no meat and want to get plant iron right.
  • You want to understand your results before your next appointment.
  • You want the whole plan on paper, not another app.

What is inside

Nine parts,
drawn as well as written.

  1. 1

    Why iron

    How iron turns oxygen into energy, the signs of running low, and what each period costs in iron.

  2. 2

    How iron moves

    The four players that decide how much iron gets in, and why inflammation locks the door.

  3. 3

    Your numbers

    How to prepare for a blood test, how to read it in five steps, and a goal for every marker.

  4. 4

    Food that counts

    Heme and plant iron, the keys and the blockers, and a whole day of iron timing drawn as a clock.

  5. 5

    The 7-day ferritin menu

    21 recipes built on one plate formula, liver made easy, and a shopping list.

  6. 6

    Taking iron well

    Three ferritin paths, why every other day works better, period week, forms and side effects.

  7. 7

    Rechecks

    When and what to retest, a realistic timeline, and how to read the result when it comes.

  8. 8

    When ferritin is stuck

    An eight-step checklist: timing, inflammation, stomach acid, blood loss, thyroid, vitamin D, protein.

  9. 9

    Your situation

    Teenagers, pregnancy, plant-based eating, training, partners, menopause and hair.

What it is not

Plain about
its limits.

  1. 01

    Not a diagnosis.

    A blood test diagnoses. The guide helps you prepare for one and understand the result.

  2. 02

    No doses.

    Your dose comes from your doctor. The guide explains how iron is taken well, not how much to take.

  3. 03

    Goals, clearly marked.

    Several goals are stricter than standard lab ranges, and the guide says so wherever they appear.

  4. 04

    Written in English.

    The guide is in English for now. Other languages may follow.

Questions

Before you buy.

Contact: hello@ferritin.ai

What do I get?

A 73-page illustrated PDF in US Letter size. It reads well on a phone, a tablet or a computer, and the trackers at the back are made to print.

How do I get it after paying?

Checkout gives you a download link straight away and sends it to your email as well.

Is it in my language?

The guide is written in English. Other languages may follow.

Is it the same as the app?

The guide explains the thinking. The app does the counting: it estimates the iron in each period you log, times your iron around coffee and tea, and keeps your lab results on one timeline. Many people read the guide first.

Will it tell me how much iron to take?

No. It explains how iron is taken well: how often, at what time and what to keep away from it. Your dose comes from your doctor.

Is it right for me if I am pregnant or under 18?

The food chapters suit nearly everyone, and the guide has a section on pregnancy and teenagers. In both cases, lab tests and supplements go through your doctor or midwife.

Where does the content come from?

From a ten-week coaching program for women with low ferritin, rewritten in plain words, drawn, and listed with its sources at the back.

Can I share it?
