IgG Colostrum Milk

I saw a few pharmacies carrying IgG Colostrum Milk.

Under "Nutritional Facts" according to the Food Safety & Quality - Labeling Department, the IgG level or even the antibody level is not permitted to be on the box. I know as I have done a few of these registration cases for Colostrum Milk.

Antibodies are proteins of more than 1,000 amino acids and the new baby could not possibly get them through the mother's milk which went into the baby's body through the mouth and stomach. The antibodies are digested into amino acids and can never be absorbed into the blood as a complete ANTIBODY. The intestines can only absorb peptides of 15-30 amino acids long.


The basic unit of each antibody is monomer. An antibody can be monomeric, dimeric, trimeric, tetrameric, pentameric etc. The monomer is a "Y"-shaped molecule that consists of two identical heavy chains and two identical light chains connected by disulfide bonds.

There are five types of heavy chain: γ, δ, α, μ and ε. They define classes of immunoglobulins. Heavy chains α and γ have approximately 450 amino acids, while μ and ε have approximately 550 amino acids.

There are only two types of light chain: λ and κ. In humans they are similar, but only one type is present in each antibody. Each light chain has two successive domains: one constant and one variable domain. The approximate length of a light chain is from 211 to 217 amino acids.
