An optimally functioning immune system prevents unwanted toxins and molecules from disturbing homeostasis. Colostrum, the easily digestible milk produced after birth, is abundant in bioactive molecules, including Igs and antimicrobial peptides, which confer passive immunity. There are five main Ig classes, the most common being IgG, which accounts for 70-75% of all serum antibodies in the body playing a major role in the immune system.

IgG Protect is manufactured using advanced filtration and purification techniques to ensure consistency in potency and purity, and provides 1,000 mg of IgG and 2 g of protein per serving.
