Milk is made up of protein, fat, carbohydrate, water, minerals and vitamins. These components are packaged inside cells within the mammary gland and are released from the cells by two different pathways of secretion.

• Merocrine secretion
  proteins, lactose, minerals and water are released without disruption of the cell.

• Apocrine secretion
  milk fat is enveloped by the cell membrane before being pinched off from the cell. In this process some of the cell components are also released into milk.

Unlike cows, goats have the same secretion method as humans. More bioactives are secreted with goat milk, such as Epidermal Growth Factor (EGF), Polyamine, and Free Amino Acids. The level of natural nutrients like Nucleotides, Taurine, as well as Glutamic Acid are even 3 times higher than cow milk's, helping to enhance protection from within and build solid foundation for mental and physical development.
