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
What is Immulox?
This is the brand name for colostrum with a high concentration of Proline-Rich Polypeptides (PRPs), the small proteins naturally occurring in colostrum. PRPs help to regulate the immune system for normal balance.*
For an overactive immune response PRPs help calm the immune system, for an underactive immune response PRP’s help stimulate the immune system.*
Immulox is featured in Symbiotics to provide more PRPs per serving, contributing to the overall balancing power of our colostrum.
