What Are Immunoglobulins?
Immunoglobulins, also known as antibodies, are vital components of the immune system[1]. These Y-shaped proteins are produced by specialised white blood cells called B lymphocytes. Immunoglobulins play a crucial role in identifying and neutralising harmful pathogens such as bacteria, viruses, and fungi. They do this by binding to specific molecules on the surface of these invaders, marking them for destruction by other immune cells or by activating complement proteins to facilitate their elimination. Additionally, immunoglobulins can also regulate immune responses and help in the recognition of self and non-self antigens, contributing to the body’s defence against infections and diseases.
Immunoglobulins and Whey Protein
In addition to their crucial role in the immune system, immunoglobulins also have significance in the context of whey protein. Whey protein, derived from milk, is a rich source of bioactive compounds, including immunoglobulins. Whey protein isolate, in particular, contains a higher concentration of immunoglobulins compared to other forms of whey protein. These immunoglobulins, primarily IgG, present in whey protein, may offer additional immune support beyond their nutritional value. Consuming whey protein may thus contribute to bolstering the body’s defences against infections[2], particularly in individuals with compromised immune function or during periods of increased susceptibility to illness. Thus, the inclusion of immunoglobulins within whey protein adds another layer of health-promoting properties to this widely consumed nutritional supplement.
