Food manufacturers compete on the market, introducing innovative products. Functional products, which show a beneficial impact on human health over the one which comes from the basic product component, are becoming increasingly important. Since a few years researchers underline a huge importance of colostrum in this trade. ‘First milk’ is significantly richer in biologically active peptides, immunologic components and growth factors than later milk.In the article an overview of literature concerning the meaning of bovine colostrum in human nutrition and its therapeutic properties was performed.A vast research which was conducted on animals, as well as in strict laboratory conditions (in vitro, in vivo) confirm clinical benefits of colostrum. A number of analyses is still conducted, which additionally refer to the design of the appropriate dose and time of treatment with colostrum. Colostrum is considered a fully safe substance. To this moment, even with very high doses, very few side effects were noted. The main functions of the colostrum are supplying the organism with essential nutrients which strengthen the immune system, stimulation of the immune system response, maintaining the intestinal microflora and tissue regeneration acceleration.Summing up, further use of products based on colostrum both in healthy individuals – prevention, as well as with some diseases is justified. The interest in questioned substance is rising due to vast scientific and clinical research underlining the significance of colostrum in feeding of human beings. Scientists predict that products based on colostrum may play a significant role on the functional products market in the future.
