What is Human Milk Lactoferrin?Updated 15 hours ago

Lactoferrin is a multifunctional iron-binding glycoprotein found in high concentrations in human breast milk—especially the early milk known as colostrum. It is part of the innate immune system, designed by evolution to protect and program the infant microbiome, immune system, and gut barrier from birth.

While lactoferrin exists in both human and bovine milk, human milk lactoferrin (hmLF) is uniquely bioactive, with structural differences that significantly enhance its function and compatibility with the human body. Until now, this exact human-identical form has only been available through breastfeeding. We’ve changed that.

At kēpos, we are the first and only company to commercialize human-identical lactoferrin for daily use in adults, created using precision fermentation. This is not bovine lactoferrin. It’s human-equivalent. That distinction matters.
