For many years, health care practitioners have been hearing a great
deal about bovine colostrum, a dietary supplement intended to optimize
the immune systems of both healthy and chronically ill individuals.
Much of the excitement about colostrum has been generated by
testimonials, anecdotal reports as well as the marketing efforts of
several new supplement manufacturers and distributors. This web site is
intended to provide reliable information about colostrum, its
attributes and the research conducted about them. The past 20 years
has also witnessed the publication of over 2000 research papers
strongly supportive of both colostrum and its numerous components, and
the goal of this website is to provide updated overview of this body of
research and some insights applicable for educated practitioners and
consumers.
Colostrum Rediscovered Historically, Ayurvedic physicians have
used bovine colostrum therapeutically in India for thousands of
years. In the US and throughout the world, conventional doctors
used it for antibiotic purposes prior to the introduction of sulfa
drugs and penicillin. In the early 1950's, colostrum was prescribed
extensively for the treatment of rheumatoid arthritis. In 1950,
even Dr. Albert Sabin, the polio vaccine developer, discovered
that colostrum contained antibodies against polio and recommended
it for children susceptible to catching polio.
What is Colostrum? Colostrum is the first mammary secretion
that a mammal provides for its newborn for the first 24-48 hours.
It contains numerous immune system and growth factors as well as
essential nutrients, trypsin and protease inhibitors that protect
it from destruction in the GI tract. It is estimated that colostrum
triggers at least fifty processes in the newborn. Bovine colostrum
is biologically transferable to all mammals, including man and is
much higher in immune factors than human mother's colostrum. Laboratory
analyses of immune and growth factors from bovine colostrum are
identical to those found in human colostrum except for the fact
that the levels of these factors are significantly higher in the
bovine version. For example, human colostrum contains 2% of IgG
while cow colostrum contains 86% of IgG, the most important of the
immuno-globulins found in the body. Bovine colostrum contains a
blocking hormone to prevent the calf from becoming sensitized to
its own mother's immune factors. Studies indicate that all species,
including man, benefit from the immune boosting properties of bovine
colostrum with no reports of allergic or anaphylactic reactions
to date. It is in a very limited supply because colostrum is only
available for a day or two after calving. The needs of the newborn
calf must be met first and only high quality colostrum is taken
from cows that have been certified free of antibiotics, pesticides
and synthetic hormones. Colostrum must be processed at low temperatures
so that the immune and growth factors remain biologically viable.
