Heme Iron - A Well-Studied Source of Iron
Our products are developed based on research on heme iron and heme iron-enriched interventions - an approach that has proven to be both effective and gentle on the stomach.
Studies show that heme iron-enriched products made with bovine hemoglobin have strong potential to improve iron status and help prevent iron deficiency, making them a natural and well-tolerated way to increase iron intake and enrich the diet with iron.
By building on established scientific knowledge and research findings, combined with advances in modern food technology, we have developed new types of supplements and iron-enrichment products that make it easier to live an iron-rich life - for both children and women.
Throughout this journey, we have been supported by a leading Swedish iron researcher whose work has hundreds of listings on PubMed. On a fully voluntary basis, the researcher contributed their expertise and played a key role in the initial development process. To maintain full independence as a researcher, they have chosen to remain anonymous.
We continue to expand our network and currently have additional contacts within Swedish iron research, which is an important asset in our ongoing product development efforts.
Here is a brief selection of studies within iron research that have contributed to our innovative products:

“In my professional role, I meet many women with iron deficiency. I see great value in iron products based on heme iron for individuals with insufficient dietary iron intake. Heme iron has high bioavailability, is generally well tolerated, and in my experience does not cause gastrointestinal discomfort to the same extent as many other iron supplements.
When it comes to children, iron requirements increase significantly from around seven months of age, and iron is essential for normal brain development. Heme iron powder for children is a flexible and easy-to-use option that makes it simple to enrich a child’s diet with iron. I use it myself for my children and find that it works very well.”
