The lipids contained in raw colostrum are only found in a reduced form in bovine colostrum products, as they are difficult for humans to digest and also have a relatively strong impact on the shelf life of the product. Although they have a certain protective function for immune factors, bind various ingredients and ensure good dissolution and distribution, the defatting doesn’t have much of an effect on the vital substances. For these reasons, defatted bovine colostrum is preferable for the finished end product.
