Bovine colostrum is the pre-milk fluid excreted by the heifer cow for a period of 72 hours after calving. It is at its most concentrated and potent for the first 24 hours and contains large amounts of immunoglobulins, growth factors, amino acids, vitamins and minerals in a uniquely balanced complex. Its antibodies and immune factors are almost identical with those found in human colostrum while the amount of immune factors is four times higher. Bovine colostrum is also non species specific, which makes it highly suitable and useful for human consumption.
The important contents that make up colostrum can be broken down into the following groups
- Growth factors
- Metabolic factors
- Amino acids
- Minerals and trace elements

However, colostrum in its raw, natural state, also contains high levels of fat, casein, albumin and other contaminants, which need to be removed. This will allow the natural connecting structures between the active substances of colostrum to remain intact. It also contains large protein molecules which bind essential nutrients and make it difficult for these to be absorbed. If the full benefit of bovine colostrum is to be made available, it is therefore of great importance to eliminate the fat and casein and to separate all the essential nutrients from the large protein molecules without damaging the components: in other words, to make available all the essential elements in a free form.
