How Breast Milk Fat Composition and Hormones Shift From Colostrum to Mature Milk
This study looked at breast milk from Egyptian mothers at two points in early lactation: colostrum (the first milk) and mature milk (produced later). Researchers measured levels of long-chain polyunsaturated fatty acids (LC-PUFAs) like arachidonic acid (AA) and DHA, along with the activity of genes (FADS1 and FADS2) that help the body convert dietary fats into these longer-chain fatty acids.
What this means for you
This is basic biology research, not a study of a supplement, and it doesn’t test any intervention. It offers a window into how breast milk composition naturally shifts during early lactation, which may be useful background if you’re curious about infant nutrition science, but it doesn’t provide guidance on personal supplementation.
