Colostrum: Not Just For Babies

Colostrum is the name of the first milk produced after birth. It is provides hormones, growth factors, immune globulins and immunity modulators while also helping to grow the GI tract microbiome. Research shows that the beneficial components of colostrum are 100-1000 times more concentrated in bovine (cow) colostrum than in that of a human.

Beneficial Components of Colostrum
  • PRPs, proline-rich polypeptides, from colostrum increase the key repair molecule brain derived neurotropic factor (BDNF) and as a result they improve the ability to learn in younger adults, enhance the ability to concentrate and reaction time in middle adults and improve the efficiency of memory processes in older adults.
  • Lactoferrin, a protein found in the highest quantity in colostrum, supports a healthy immune defense and can encourage intestinal growth of beneficial bacteria.
  • Lysozyme is an immune factor that attacks pathogenic bacteria.
  • Colostrum is high in IgG an antibody that is vital for preventing infections. It also contains other immunoglobulins.
  • Serum derived bovine immunoglobulin (SBI) is an isolated protein that contains high levels of immunoglobulins, especially IgG, but it does not contain dairy.


Additional Colostrum Benefits in Research
  • Bovine colostrum (BC) supplementation in male athletes was linked to a reduced incidence of upper respiratory illness and a reduction in the number of symptomatic days. Gut permeability also improved.
  • Infants and toddlers with acute diarrhea who received colostrum experienced less vomiting, diarrhea and fever after 48 hours and by 7 days, none of the BC children were experiencing symptoms. In another study involving children ages 1-6 with recurrent upper respiratory infections, BC reduced the number of infections and hospitalizations.
  • In older adults, BC increased leg strength and reduced bone resorption suggesting that BC may support bone health.
  • A topical BC formula improved vaginal dryness.
  • BC provided protection against NSAID use intestinal damage.
