Mega IgG2000 is a dairy-free immunoglobulin concentrate that supports healthy digestion and maintains healthy 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 maintaining healthy gut barrier function. The serum immunoglobulin in Mega IgG2000 has been the subject of over 10 published human clinical trials.
How Mega IgG2000 Works
Prebiotics feed. Probiotics populate. IgG clears the battlefield.
While probiotics add beneficial bacteria and prebiotics feed them, immunoglobulins handle a different job entirely — binding and neutralising the harmful agents that damage your gut lining.*
Neutralise harmful agents
IgG antibodies bind a wide variety of pathogens — bacteria, viruses, fungi, and their toxic by-products — directly in the gut lumen, reducing the toxic burden on your body.*
Strengthen the gut barrier
By neutralising LPS endotoxins and other harmful agents, Mega IgG2000 reduces the damage that triggers intestinal permeability, helping maintain the integrity of your mucosal barrier.*
Reduce immune activation
By stopping harmful antigens before they can breach the gut barrier, Mega IgG2000 helps decrease unnecessary immune activation and supports a calmer inflammatory response.*
Broad-Spectrum Binding
IgG binds what's attacking your gut.
Immunoglobulin G doesn't just target one pathogen — it binds a broad range of harmful organisms and their toxic by-products. These antibodies are unaffected by antibiotics, so they keep working even during treatment protocols.
Each serving delivers 900mg of IgG — a concentrated dose of pre-formed antibodies that go to work immediately, without requiring your immune system to expend energy producing its own.
LPS Endotoxins
Binds lipopolysaccharides — the inflammatory toxins produced by gram-negative bacteria that drive metabolic endotoxemia.*
Pathogenic Bacteria
Binds E. coli, Salmonella, Staphylococcus, H. pylori, and other harmful bacteria, neutralising them for safe removal.*
C. difficile Toxins
IgG binds C. diff. toxins A and B, improving infection symptoms and helping resolve diarrhoea.*
Viruses, Fungi & Mycotoxins
Provides broad protection against viral and fungal agents, including mycotoxins produced by certain moulds.*
The Difference
The dairy-free alternative to colostrum.
Most immunoglobulin supplements are derived from milk (colostrum) — which can increase gut inflammation in people with dairy sensitivities. Mega IgG2000 uses ImmunoLin®, isolated directly from bovine blood serum, not milk.

Answers
Frequently asked questions.
What is Mega IgG2000 and how is it different from probiotics?
Mega IgG2000 is a concentrated immunoglobulin supplement — it delivers pre-formed antibodies (IgG, IgM, IgA) that bind and neutralise harmful pathogens and toxins in your gut. Probiotics add beneficial bacteria, and prebiotics feed them. Mega IgG2000 handles a complementary task: clearing the harmful agents that damage your gut lining. They work best together.*Is Mega IgG2000 dairy-free?
Yes. Unlike most immunoglobulin supplements that are derived from milk (colostrum), Mega IgG2000 is derived from bovine serum — making it completely lactose-free, casein-free, and β-lactoglobulin-free. However, it is bovine-based, so it should not be consumed by anyone with a beef allergy.Should I choose capsules or powder?
Both formats deliver the same ImmunoLin® ingredient and the same dose of immunoglobulins per serving. Capsules are convenient and easy to take (4 capsules = 1 serving, ages 8+). The powder format has no other ingredients — just pure ImmunoLin® — and is suitable for ages 2+, making it ideal for younger children or anyone who prefers mixing into water.Can I take Mega IgG2000 with antibiotics?
Yes. The immunoglobulins in Mega IgG2000 are unaffected by antibiotics or antimicrobial remedies. This makes it an excellent companion during and after antibiotic treatment, when the gut is especially vulnerable to harmful organisms and toxin accumulation.*When should I take it?
Capsules can be taken between meals, before bedtime, or as directed by your practitioner. The powder can be taken with or without food. Many users notice initial improvements within days, with more consistent results building over 4–6 weeks of regular use.*What should I pair it with?
Mega IgG2000 pairs especially well with a spore-based probiotic. While a probiotic reconditions the gut with beneficial bacteria, Mega IgG2000 handles the cleanup — binding and removing the harmful agents that work against your microbiome. Many practitioners recommend using both as part of a comprehensive gut restoration protocol.*
