What does the label tell you?

The composition review describes liquids, powders, pills and tablets. A capsule count alone does not show whether its daily quantity resembles the product used in a trial. Compare the actual amount of colostrum with the study’s formulation and amount; the literature spans very different quantities. 1 2 3

Immunoglobulin G, often shortened to IgG, is one component of colostrum. Because the product is a mixture and its composition varies, an IgG percentage alone cannot reproduce the clinical evidence for a particular preparation. The adult studies reviewed used different products and control formulations. 1 3
