Colostrum is the pre-milk fluid produced by mammalian mothers during the first few days after giving birth. (It is not milk, so those with milk allergies need not worry.) The purpose of colostrum is to transfer immunity and protection against disease from a mother to her newborn. It is said to contain high levels of protein and antibodies. Colostrum naturally contains a broad range of amazing immune boosters. These include immunoglobins, the body's first line of defense; hormones; enzymes; growth factors; peptides; and nucleotides. Colostrum simply is perfect nutrition for the skin. Its immune and healing components promote healthy skin and protect it from environmental aggressors, providing an impermeable protective barrier against toxins and pathogens.
