Colostrum is a form of pre-milk produced in mammals after giving birth. It is naturally thicker than milk, and is packed with the necessary vitamins, minerals and nutrients that help to develop a healthy-functioning immune system and gastrointestinal tract (ie, the gut).

Bovine colostrum, specifically, is a rich natural source of macro- and micro-nutrients, immunoglobulins, and proteins with anti-microbial activity and growth factors. It is recommended as a supplement in humans to support general, digestive and immune health.

Bovine colostrum differs from human colostrum in a few key ways:

Bovine colostrum actually contains less lactose than human colostrum (surprisingly).

The antibodies found in human colostrum consist primarily of immunoglobin A (IgA). Bovine colostrum contains a high concentration of IgA, as well as immunoglobulins G (IgG), E (IgE), D (IgD), and M (IgM). It also contains about 40 times more antibodies total than human colostrum.

Bovine colostrum contains a higher concentration of insulin-like growth factor (IGF) than human colostrum – this compound is used throughout the body in development of bone, muscles, and new tissues. Bovine colostrum also, conveniently, contains special enzymes that prevent growth factors from being digested.

Colostrum can be helpful in aiding the body to address issues that start in the gut. The extra antibodies and other nutrients can help to shore up the health of your gut and immune system. Additionally, the natural growth factors in colostrum are known to promote the regrowth of cells throughout the body – including skin cells.
