We offer Primal Dose Colostrum to promote everyday good health for normal, healthy digestive and immune system function.*

This is custom heading element

Colostrum is nature’s first food – provided by all female mammals to their offspring for the first couple of days after birth. Colostrum contains a combination of known immune factors, including Immunoglobulins, naturally occurring growth factors, Lactoferrin and Proline-Rich Polypeptides for immune system modulation to promote the healthy development and function of the immune system at birth.*

As our pets age, the amount of these immune and growth factors present in their bodies begins to decline. As a result, they may feel less energetic, gain unwanted weight, and lose muscle tone – even though your pet exercises regularly and eat a healthy diet.

Colostrum Plus Components

These elements of colostrum have been studied extensively and are present in the guaranteed amounts as labeled on Symbiotics products:

Proline-Rich Polypeptides (PRPs)

PRPs act systemically, modulating the complex immune system so that it can better respond as needed.*

Naturally occurring Growth Factors

Colostrum contains many naturally occurring growth factors. Growth factors are peptides that function as inter-cellular signaling molecules to turn on or turn off production of specific proteins in the target cells. They assist in completing the growth, development and maintenance of a healthy gut wall.*

Immunoglobulins (IgG, IgA, IgE, IgM, IgD)

Immunoglobulins are antibodies. They play a key role in maintaining a healthy immune system and GI tract.*


Lactoferrin is an iron-binding protein found in most immune cells and its receptors have been found on most immune function cells including lymphocytes, monocytes, macrophages and platelets.*
