Ferrous sulfate, iron bisglycinate, liposomal or sucrosomial iron: the choice can be confusing. A suitable preparation should be effective, tolerable and something you can actually take in daily life.

Traditional ferrous salts

Ferrous sulfate and other traditional iron salts are well studied. With an appropriate indication, they can be effective and are often inexpensive. However, nausea, abdominal pain, constipation or diarrhoea can make intake difficult.

Iron bisglycinate

In this form, iron is bound to glycine. It may offer an alternative for some people with tolerability problems. This does not establish general superiority for every deficiency or dose. Differences in the evidence and the respective target group must be considered.

Liposomal and sucrosomial iron

These offer iron in special formulations. They may be of interest in certain situations. However, the evidence is not the same for all products, doses and patient groups. Terms on the packaging do not replace checking elemental iron amount, indication and progress.

Do not compare doses by tablet size

Two preparations may contain different amounts of elemental iron. The number “100 mg” alone is not always comparable without reference to the iron amount. Recommendations from hepcidin studies with traditional iron salts also cannot be transferred in every detail to every newer form.

What is the practical decision?

A preparation you tolerate well and can take reliably is often more useful than frequent changes without follow-up. If values remain low, blood loss and absorption problems must also be considered. A higher price does not guarantee a better ferritin increase.

The AGA finds no general superiority of one oral formulation. Instead of a blanket product recommendation, we therefore discuss the starting situation, tolerability and treatment goal.

The iron tablets check lets you review preparation type, dose information and schedule together.
