Colostrum is the nutrient rich pre milk that is secreted by the mammary glands of female mammals to nourish their young during the first 72 hours after giving birth. Colostrum is a breast fluid produced by humans, cows, and other mammals before breast milk is released. It’s very nutritious and contains high levels of antibodies, which are proteins that fight infections and bacteria. Colostrum promotes growth and health in infants and newborn animals, but research shows that taking bovine colostrum supplements may promote immunity, help fight infections, and improve gut health throughout life.
- Lactoferrin. Lactoferrin is a protein involved in your body’s immune response to infections, including those caused by bacteria and viruses.
- Growth factors. Growth factors are hormones that stimulate growth. Bovine colostrum is especially high in two protein-based hormones, insulin-like growth factors 1 and 2, or IGF-1 and IGF-2 .
- Antibodies. Antibodies are proteins, also known as immunoglobulins, used by your immune system to fight bacteria and viruses. Bovine colostrum is rich in the antibodies IgA, IgG, and IgM.
