Product Overview

Microbiome Labs Mega IgG2000 is a serum-derived bovine immunoglobulin concentrate that delivers concentrated IgG antibodies directly to the gut lumen. Unlike colostrum-based IgG products, Mega IgG2000 is sourced from bovine serum — making it dairy-free and suitable for individuals with dairy sensitivities while still providing a highly concentrated immunoglobulin fraction.

Immunoglobulin G (IgG) is the most abundant antibody in the human body and plays a central role in mucosal immune defense. When delivered orally, serum-derived IgG has been clinically studied to support gut barrier integrity, reduce intestinal permeability, bind and neutralize gut antigens, and support a healthy intestinal microflora balance. Mega IgG2000 is widely used in functional medicine protocols for leaky gut, IBS, and immune support.

Frequently Asked Questions

What is IgG, and how does Mega IgG2000 support gut health?

Immunoglobulin G (IgG) is the most abundant antibody class in the human body and plays a central role in immune defense. When delivered orally, serum-derived IgG travels to the gut lumen where it can bind and neutralize antigens, toxins, and pathogens — supporting mucosal immune defense without systemic absorption. Clinically, oral IgG supplementation has been studied for its ability to support gut barrier integrity, reduce intestinal permeability (leaky gut), and promote a healthy intestinal microflora balance.

How is Mega IgG2000 different from colostrum-based IgG supplements?

Most IgG supplements on the market are derived from bovine colostrum or whey, which contain lactose and dairy proteins that can be problematic for individuals with dairy sensitivities or lactose intolerance. Mega IgG2000 is sourced from bovine serum — not colostrum or whey — making it dairy-free while still delivering a highly concentrated immunoglobulin fraction. Serum-derived IgG also tends to have a higher IgG concentration per gram compared to colostrum-based sources.

Is Mega IgG2000 appropriate for leaky gut or intestinal permeability concerns?

Yes — Mega IgG2000 is one of the most commonly recommended immunoglobulin supplements in functional medicine protocols for intestinal permeability (leaky gut). Clinical studies on serum-derived bovine immunoglobulins have demonstrated support for gut barrier integrity and reduction in markers of intestinal permeability. It is often used alongside other gut-supportive supplements such as MegaSporeBiotic and MegaPreBiotic as part of a comprehensive gut restoration protocol. Consult your healthcare provider for personalized guidance.

Is Mega IgG2000 safe for people with dairy allergies or sensitivities?

Mega IgG2000 is dairy-free — it is derived from bovine serum, not from milk, colostrum, or whey, and does not contain lactose or casein. It is generally well-tolerated by individuals with dairy sensitivities or lactose intolerance. However, because it is derived from bovine (beef) sources, individuals with known beef or bovine protein allergies should consult their physician before use.

Can Mega IgG2000 be taken with other Microbiome Labs products?

Yes. Mega IgG2000 is commonly used as part of a comprehensive Microbiome Labs gut health protocol alongside MegaSporeBiotic (spore probiotic), MegaPreBiotic (prebiotic fiber), and HU58 (Bacillus subtilis). The immunoglobulins in Mega IgG2000 work synergistically with probiotics and prebiotics to support a healthy gut environment from multiple angles. It is also compatible with most other dietary supplements.

How should Mega IgG2000 capsules be stored?

Store in a cool, dry place away from direct sunlight, heat, and humidity. Keep the bottle tightly closed when not in use. No refrigeration is required. Refer to the expiration date printed on the bottle for shelf life. Microbiome Labs products are manufactured to strict quality standards and tested for potency and purity.
