Mega IgG2000TM is a dairy-free immunoglobulin concentrate that supports healthy digestion, neutralizes microbial and environmental toxins, while improving gut barrier function. Unlike other milk-derived immunoglobulins on the market, Mega IgG2000 is derived from bovine serum, making it lactose-free, casein-free, and β-lactoglobulin-free.

This unique alternative to bovine colostrum supports a healthy mucosal immune system by decreasing unfavorable immune activation in the mucosal layer, lowering toxic burden and strengthening gut barrier function. The serum immunoglobulin in Mega IgG2000 has been the subject in over 10 published human clinical trials on inflammatory and infectious bowel conditions. It is made by the same company that makes MegasporeBiotic.

Immune Response

When an antigen enters the body, it elicits a response from the innate and adaptive branches of the immune system. The adaptive immune response utilizes B and T lymphocytes to find foreign antigens, neutralize them, and eliminate them from the body. B lymphocytes do this by producing antibodies, or immunoglobulins, that can bind to unwanted antigens and remove them from the system.

Immunoglobulin G (IgG), the most abundant antibody in the system, can be found in blood and extracellular fluid, allowing it to control infections in the body. IgG antibodies can bind a variety of pathogens, including bacteria, viruses, and fungi, as well as their toxic by-products. Binding these toxins will neutralize them and allow the immune system to safely remove them from the body.


Ages 2+. Take 4 capsules daily with or without a meal, or as directed by your healthcare professional. If you are sensitive, it may be wise to start at a low dose and slowly increase as tolerated.

Mega IgG2000 is a beef-derived product that does not contain any dairy, lactose, or casein. Do not consume if you have an allergy to beef.
