Prolactin

Definition

Prolactin is a hormone produced by the pituitary gland that primarily promotes lactation (milk production) in mammals after childbirth.

Scientific / Technical Definition

Prolactin is a peptide hormone synthesized and secreted by the lactotroph cells of the anterior pituitary gland. It plays an essential role in lactogenesis by stimulating the mammary glands to produce milk postpartum. Additionally, prolactin influences reproductive and metabolic processes, modulates the immune system, and helps regulate osmotic balance.

Benefits

• Stimulates breast milk production after childbirth.
• Supports the immune system functionality.
• Involved in reproductive health, affecting behaviors and functions.

Examples

• Although prolactin is a hormone and not obtained through food, its production can be influenced by dietary intake, stress levels, and physiological changes during pregnancy and postpartum.

Additional Information

• Effects: Prolactin has various regulatory effects, including promoting milk production, influencing behavior and metabolism, and impacting reproductive functions.
