Colostrum is known as “liquid gold” in the pediatric world, It is the milk produced by mammals in the first days postpartum. This thick, golden yellow liquid is packed with nutrients and antibodies crucial to the development of newborns’ immune systems.
The importance of colostrum in child development is indisputable but in the field of nutrition, the so-called “Superfoods” such as colostrum powder have captured the attention of the market, driving companies to create products to meet this demand. However, questions arise about the effectiveness and benefits of colostrum powder. To clarify this, we turned to nutrition experts.
Unlike fresh colostrum, powdered colostrum intended for adults comes in dry form. Melissa Groves Azzaro, registered dietitian and owner of The Hormone Dietitian, notes that the nutritional composition of supplemental bovine colostrum varies depending on the brand and form of the supplement.
In the EatingWell article, the specialist highlights that bovine colostrum is noticeably richer in proteins, immunoglobulins and antimicrobials than normal cow’s milk. However, these differences are seen in its liquid form, not powder.
A major limitation is the paucity of research on colostrum powder and its nutrients. Taylor Wallace, a professor at George Mason University, explains in the same article that the manufacturing process for bovine colostrum involves heat treatment, which alters key nutrients such as lactoferrin, a protein with antiviral and antibacterial properties.
Additionally, stomach acid can affect the active components of the supplement, making it uncertain which nutrients are actually absorbed by the body and how they impact health.
Given the lack of conclusive data on powdered colostrum, both Wallace and Azzaro advise caution with its use. Review of 28 studies on bovine colostrum suggests it could be recommended to improve the microbiome in the future and digestive health, although there is currently not enough evidence to support these claims.
Natural colostrum has a well-documented effect on the immune system of newborns, but its impact on adults is still uncertain.
Azzaro says that, although research is limited, colostrum could benefit adults because much of the immune system resides in the intestines. Additionally, the vitamin D present in colostrum may influence the immune response, although this research is preliminary.
Unless under medical supervision, Azzaro does not recommend adding colostrum supplements to the diet. “It’s not appropriate for everyone,” he says, stressing that the lack of data makes it difficult to justify its purchase, questioning whether it is really worth the cost or whether it would be a waste of money.
In conclusion, while colostrum in its natural form is crucial for newborns, the powdered version for adults requires more research to determine its effectiveness and safety. Before considering its inclusion in the diet, it is essential to consult with a health professional to evaluate its suitability and avoid possible risks.
