Colostrum is sometimes called “first milk” as it is the milk that is produced by mammals right after they give birth and before the breast milk comes in. In general, colostrum has a higher amount of protein than regular milk. It also contains a number of essential nutrients like vitamin A, sodium chloride, and more, which is one of the reasons it is essential when you are younger. It also offers babies support for digestive system health and development.
Colostrum also contains lactoferrin (helping with your body's immune response), growth factors (stimulating growth), and antibodies (immunoglobulins that your immune system uses to fight bacteria and viruses). Colostrum may also offer support for digestive system health in adults when taken as a supplement. Many athletes also choose to take a colostrum supplement because it supports the maintenance of lean muscle mass and promotes overall muscle health. It also works to support a healthy recovery after exercise.
A major source of colostrum supplements are from bovine colostrum which is loaded with nutrients that fight disease and promote growth. It may be able to boost immunity, treat infections, and offer more related benefits in humans throughout life also.
