Swanson High Immunoglobulin Colostrum 500 mg 120 Caps 4 Pack

For a unique way to support your immune system, go back to the beginning with Swanson High Immunoglobulin Colostrum. Colostrum is the first milk produced by a mother for her offspring. It is an amazing source of nutrients including beneficial fatty acids, antibodies, peptides and proteins, vitamins and minerals, all of which contribute to the newborn's ability to thrive. Colostrum is also a source of growth factors, amino acids, oligosaccharides and immune regulators. It has been studied for its ability to support several areas of health, including respiratory, gastrointestinal and metabolic, plus physical performance and healthy aging. We use bovine colostrum sourced from mature USDA dairy cows not treated with antibiotics. It is shipped frozen and then low-heat dried to preserve the proteins, fats and other nutrients. One of the most important nutrients in colostrum is a type of glycoprotein known as immunoglobulins which bind to and destroy unwelcome bacteria or viruses. Among immunoglobulins, type G (IgG) is the most common. IgG antibodies may support the activity of natural killer (NK) cells for a robust immune response. Swanson High Immunoglobulin Colostrum is standardized to a potent 40% IgG content.
