Everything about Eisen
All articles on Eisen — from dosage to timing, explained clearly.
Too much iron: when does it get critical?
Iron has no tolerable upper level — which does not mean harmless, but not derivable. What EFSA and the BfR state instead, and who should wait without a deficiency.
Iron and inulin: why the fibre is in the tablet
Inulin is said to improve iron absorption via the colon. In humans that has been tested three times — and the amounts in a tablet are tiny.
Iron daily requirement: 11, 14, 16 or 27 mg?
Men 11 mg, menstruating women 16 mg, pregnancy 27 mg: what the DGE recommends — and why the label still shows 14 mg as its reference value.
Spotting iron deficiency: ferritin, TSAT or Hb?
Ferritin falls first, haemoglobin last. Which blood values show iron status, which cut-offs apply and why ferritin cannot be read without an inflammation marker.
Iron-rich foods: the table by portion
Liver tops every ranking, parsley sits near the top — neither helps at the shop. What usual portions deliver, and how much of it is absorbed.
Buying iron: price per day, not price per mg
Twice the milligrams is not twice the iron. What actually makes two iron packs comparable: the amount, the compound, the additives and the days covered.

Taking iron: fasting, in the morning, every other day
On an empty stomach in the morning most of it arrives, and every other day beats daily. What is measured on timing, zinc and calcium.
Iron absorption: vitamin C, coffee and tea
Vitamin C with a meal raises iron absorption, black tea cuts it by up to 94 %. What has been measured — and why the gap is usually placed the wrong way round.
