IBCLC Practice Exam 2025 – Complete Preparation Guide

Colostrum is known for its unique composition, which includes a high concentration of immune-protective factors that play a crucial role in the early stages of an infant's life. These factors, such as immunoglobulins (particularly IgA), lactoferrin, and various cytokines, help to provide the newborn with essential immunity against infections during a time when their immune system is still developing. This protective function is one of the primary reasons why colostrum is often referred to as "liquid gold," as it offers significant health benefits to newborns.

The other statements about colostrum do not accurately reflect its characteristics or the scientific understanding of its composition. For example, while it is true that colostrum may not contain traditional medications, its immune-protective components can significantly impact the infant's health, thus making the statement about it containing no medications misleading. Additionally, colostrum is relatively low in fat (lipids) compared to mature breast milk, which provides more energy once the infant grows. Lastly, colostrum is produced before the onset of full milk production, beginning during pregnancy and continuing for a few days post-birth.
