Immunoglobulins bind, recognize, and destroy bacteria, toxins, viruses, and other antigens. The body produces antibodies to fight off antigens. Then, the next time an antigen enters the body, it stimulates the production of identical antibodies.
The importance of immunoglobulins is key to understanding why bovine colostrum supplementation may be critical to human health. Immunoglobulins and other active immune components in bovine colostrum have been shown to help reduce the risk of autoimmune, infectious, and idiopathic (unknown cause) conditions, including: Chicken pox， Hepatitis， Measles.
Raw, fresh bovine colostrum contains several different types of immunoglobulins: IgA, IgG, IgM, IgE, IgD
immunoglobulin g (IgG): Used to address immune system problems and infections. Bovine colostrum contains more IgG than any other immunoglobulin.
What is IgG?
Antibodies are major components of humoral immunity. IgG is the main type of antibody found in blood and extracellular fluid, allowing it to control infection of body tissues. By binding many kinds of pathogens such as viruses, bacteria, and fungi, IgG protects the body from infection. These antibodies protect you against infection by “remembering” which germs you’ve been exposed to before.
The normal level IgG, serum IgG levels are usually less than 200 mg/dL, and IgM and IgA levels are less than 20 mg/dL. Peripheral blood CD19+ B-cell counts are commonly less than 0.1%.
IgG is the only human immunoglobulin to pass from mother to fetus to transfer immunity.
