During which stage is breastmilk notably yellower?

The colostrum stage is characterized by the production of colostrum, which is the first form of milk produced by the mother following childbirth. Colostrum is typically thicker and has a yellowish color due to its high concentration of beta-carotene, a precursor to vitamin A. This distinctive yellow hue is an indicator of its rich nutrient profile, which is beneficial for the newborn in terms of immunity and nutrition.

Colostrum is produced in small quantities during the first few days postpartum, and its composition is specially tailored to meet the newborn's needs, providing essential antibodies and nutrients that are crucial for the baby's initial growth and development. After this stage, the milk transitions into transitional milk and eventually to mature milk, which has a more bluish color and a different composition. This understanding highlights why the colostrum stage is noted for its yellowness, as it signifies a vital part of the breastfeeding journey.
