Abstract
A bone reinforcing agent comprising a basic protein fraction or a basic peptide fraction derived from milk as an effective component is described. The basic protein fraction is obtained by passing milk or a raw material derived from milk over a cation exchange resin and eluting the adhered fraction. The basic peptide fraction is obtained by hydrolyzing the basic protein fraction with a protease. The basic protein fraction and basic peptide fraction of the present invention promote the growth of osteoclasts and suppress the resorption of osteoclasts, and thereby strengthening bone when administered orally. The invention is useful for treating or preventing bone diseases such as osteoporosis.
