Human vs Bovine Colostrum

The first food breasts make is colostrum – a sticky, yellow fluid that contains everything the baby needs after he/she is delivered. 

Commercially available colostrum typically consists of bovine colostrum.  So what does human colostrum and bovine colostrum have in common?  Although different, both have important components that support the body.

Immunoglobulins (antibodies) are found in both human and bovine colostrum. Human colostrum consists primarily of IgA, one of the most common antibodies in an individual’s body. IgA is found in the secretions of the mucosal surfaces, such as tears and saliva.

Both contain growth factors.  Human colostrum contains two unique growth factors, CAGF and CBGF. CAGF serves as an epidermal growth factor, while CBGF promotes platelet differentiation.  Bovine colostrum contains a higher concentration of insulin-like growth factor (IGF) than human colostrum. It also contains special enzymes that prevent growth factors from being digested.

Human colostrum contains a high amount of lactose. While bovine colostrum contains less lactose than human colostrum. Bovine colostrum also includes a higher concentration of casein, a protein that provides the building blocks of muscle, than human colostrum.

Both human and bovine colostrum have the following, same components:

• Contributes to the health of the GI tract*
• Improves occasional diarrhea in children*
• Contains Proline-rich Peptide (PRP) and Lactoferrin
  • Helps balance the immune system*
• Contains Growth Factors (IGF)
  • Supports muscle grown and formation*
• Contains Secretory Immunoglobulin (S-IgA)
  • Anti-bacterial components*
