Breastfeeding is a natural process, yet many new mothers face challenges with milk supply. While factors like stress and nutrition are well-known contributors, emerging research highlights the significant role of breast-milk production genetics, including prolactin gene variants, in influencing lactation success.

The Genetic Influence on Lactation

Recent studies have identified specific genetic variations that can impact milk production. For instance, mutations in the prolactin receptor (PRLR) gene can disrupt the hormonal signals necessary for milk synthesis. Similarly, variations in genes like MFGE8 have been associated with lactation difficulties in some women.

Understanding these genetic factors is crucial, as they can help identify underlying causes of low supply and guide effective interventions.

The Role of Prolactin and Its Receptor

Prolactin is a hormone essential for milk production. It binds to its receptor on mammary gland cells to stimulate milk synthesis. Variants in the prolactin receptor gene can impair this binding, leading to reduced milk output. Recognising these prolactin gene variants can be key in addressing lactation issues.

Personalised Nutrition and Lactation Support

Genetic insights can inform personalised nutrition strategies to support lactation. For example, understanding one’s genetic predisposition can help tailor dietary plans that include milk-boosting foods rich in essential nutrients. This personalised approach ensures that mothers receive the specific support they need based on their unique genetic makeup.
