How is colostrum made?
Colostrum is typically derived from the first 50 litres of mother's milk post-birth of the calf. The calf itself only requires mothers milk for the first 10 or so litres thereafter its immune system is in place. A percentage of the excess milk can then be used to produce colostrum. Colostrum is produced in the first 12 hours, when milk is at its most nutrient dense. The product comes from dairy farms in Europe and is ethically sourced, i.e. production of this product is restricted to ensure ample supply of milk remains for the calf.
What is IgG?
IgG is an abbreviation of Immunoglobulin G, a type of antibody. The IgG content of proto-col colostrum is measured by radial immunodiffusion (RID) to ensure the 30% refers to active IgG. Many colostrum products on the market are far lower in IgG and don’t differentiate between active and denatured IgG content. As well as IgG, proto-col colostrum has been shown to increase salivary IgA levels (Immunoglobulin A). Colostrum 30%+ Active IgG uses a low heat spray drying process to ensure the product's integrity.
