What is Colostrum?

Colostrum is the first milk produced by all mammals after birth and is particularly rich in immunoglobulins, immune supporting peptides (lactoferrin & lactoperoxidase) and other bioactive molecules, including growth factors. Combined, the bioactive natural compounds found in colostrum help promote immune health and support normal gastrointestinal tract health.*

The colostrum used in PROSymbiotics® specifically comes from cows, which have some of the richest colostrum among all mammals on earth. Specifically, the key components found in colostrum include:

  • Immunoglobulins
  • Lactoferrin
  • Proline Rich Polypeptides (PRPs)
  • Growth Factors

Key Components of Colostrum

Immunoglobulins: Specific types of proteins used by the immune system to support overall health:*

  • igA: Plays a critical role in mucosal immunity.*
  • igD: Signals to the cells to take part in the defense of the body.*
  • igE: An antibody class concerned with immediate hypersensitivity reactions.*
  • igG: The most abundant type of antibody, which  is found in all body fluids and provides the broadest immune support of all the immunoglobulins.*
  • igM: Is found mainly in the blood and lymph fluid, it’s the first antibody to be produced for any type of immune support.*

Lactoferrin: The second most abundant protein in breast milk. It’s an iron-binding protein responsible for conferring immunity on newborns in the first few weeks of life. It also limits the availability of iron to certain bacteria in the intestines, which supports healthy bacteria to thrive in the gut.*

Proline Rich Polypeptides (PRPs): Hormones that regulate the thymus gland (bodies central command for the immune system) as well as Cytokines – the intracellular communication system for your body.*

Growth Factors: Growth factors such as IGF-1 and IGF-2, as well as transforming growth factor β and related growth factors, help stimulate cell growth, cellular differentiation and cell maturation. Combined, the bioactive natural compounds found in colostrum help support immune health and normal gastrointestinal tract health.*
