Comments	The protein concentration of human milk is high during early lactation, the colostrum period. Then it gradually declines to a relatively low level of 0.8-1.0% in mature milk (Table link), particularly when compared to most other species (Hambraeus, 1977). Data in table are means±SD adapted from primary sources.
