Can Bovine Colostrum Supplements Benefit Your Skin and Gut Health?

In the pursuit of healthier, more resilient skin, researchers continually explore new frontiers. The health benefits of bovine colostrum are numerous, ranging from supporting skin resilience to gut health. One promising avenue is the use of bovine colostrum supplementation, the first milk from cows shortly after giving birth. This nutrient-rich substance is packed with bioactive components that may help support skin health.

The Science Behind Bovine Colostrum and the Immune System

Bovine colostrum contains a plethora of biologically active substances, including growth factors, vitamins, fatty acids, hormones, immunoglobulins, and antimicrobial peptides.(1) Similar to human colostrum, bovine colostrum is rich in bioactive components that support immune function and tissue repair. These elements contribute to its potential for promoting tissue development, repair, and maintaining a healthy immune system.(2)

A recent study published in The FASEB Journal highlights the potential of bovine colostrum in promoting the differentiation of human primary keratinocytes, the predominant cell type in the epidermis. This differentiation is crucial for maintaining skin integrity and function, as it involves the transition of keratinocytes from a proliferative state to a differentiated, stratified form.(1)

Bovine Colostrum Key Findings

Promotion of Cell Differentiation

Bovine colostrum supplementation enhances the expression of differentiation markers such as keratin 1, involucrin, and filaggrin. These markers are essential for the proper formation and function of the skin barrier.(1)

The study showed a significant increase in the number of keratinocytes expressing these markers when treated with bovine colostrum, indicating its effectiveness in promoting skin cell differentiation.(1) Much like human milk, bovine colostrum contains essential nutrients that support cell differentiation and overall skin health.

Stratification and Barrier Function

Bovine colostrum was found to promote not only the differentiation but also the stratification of keratinocytes, leading to the formation of a multi-layered epidermis (aka the outermost layer of skin). Just as bovine colostrum supports gut health by enhancing intestinal cell growth, it also supports skin health by promoting keratinocyte stratification. Why does that matter? This stratification is vital for the skin’s barrier function, protecting against physical, chemical, and biological interference(1) - Essentially, it helps skin do it’s thing! Hyperimmune bovine colostrum has been shown to be particularly effective in treating conditions such as inflammatory bowel distress and respiratory infections.

The study also highlighted the role of calcium and growth factors in this process, suggesting that while calcium contributes to the initial phase of differentiation, the cooperation with growth factors is essential for achieving terminal differentiation.(1)

Practical Implications

Taking bovine colostrum supplements could be a valuable approach for improving skin health, especially for conditions characterized by impaired barrier function. The findings from this study suggest that bovine colostrum could be a valuable ingredient in products aimed at improving skin health, especially for conditions characterized by impaired barrier function, such as psoriasis and atopic dermatitis. Its ability to promote keratinocyte differentiation and stratification can help restore the skin barrier, enhancing its protective functions. Additionally, bovine colostrum has shown promise in managing inflammatory bowel distress, further underscoring its potential health benefits.(3)


The research underscores the potential of bovine colostrum as a natural, bioactive substance that can significantly support skin health. By promoting the differentiation and stratification of keratinocytes, it helps maintain the integrity and functionality of the skin barrier, offering a promising solution for various skin conditions. Overall, oral bovine colostrum offers a promising solution for various skin conditions by promoting the differentiation and stratification of keratinocytes. Moreover, bovine colostrum supplementation may reduce the incidence of upper respiratory tract infections, as suggested by several clinical trials.(4)
