Colostrum is the only natural product to contain active immune factors such as antibodies. Antibodies are a key part of the immune system, which is a system of biological structures and processes that works to protect against disease and eliminate pathogens. Antibodies are crucial to the body's natural defensive system secreted from the immune cells called B-cells. Other immune cells of the immune system include T-cells, natural killer cells, plasma cells, stem cells and a range of chemical messengers that help recognise and destroy disease causing agents.
When we get sick, usually an infection by bacteria or virus, specialised immune cells recognise them from the body and target them for elimination. The invaders are recognised by features on their cell surface called antigens - which are markers on the cell surface indicating they're "invaders". Chemical messengers and other immune cells sends a message to B-cells and Plasma cells about the invasion and these cells start producing antigen-specific antibodies to eliminate bacteria or virus from the body.
The active antibodies are Y shaped proteins called immunoglobulins, there are various classes of immunoglobulins such as immunoglobulin G (IgG), IgA, IgM IgE and IgD. Each have a slightly different immune function in the body. IgG is the predominant antibody that provides the majority of antibody-based immunity against invading pathogens. Antibodies work through tailored sticky ends which bind to the antigens on the invading pathogen. This binding prevents pathogens from attacking body cells and essentially inactivating their invasion.Most pathogens enter the body through the mouth and the gut. By providing active antibodies through ingestion, protection against bacteria and virus can be achieved.
There are many factors in our daily lives that can affect the immune system in a negative way. Factors such as stress, poor diet, illness, antibiotics, age, exercise, and even genetics can alter balance of our immune system and result in lowered immunity which in turn increases illness.
