  • Dairy-Free Bovine Immunoglobulin Concentrate - Unlike a traditional milk-derived IgG supplement, Mega IgG2000 is derived from serum bovine immunoglobulin, making it lactose-free, casein-free, and B-lactoglobulin-free.
  • Immune & Gut Support - Bovine IgG is designed to support a healthy gut and GI detox. This unique alternative to bovine colostrum capsules supports a healthy mucosal immune system by maintaining healthy gut barrier function.*
  • Clinically Trialed Ingredient - The serum immunoglobulin in Mega IgG2000 has been the subject in over 10 published human clinical trials.* The dairy-free immunoglobulin supplement can help support healthy digestion, detoxification, and gut barrier function.*
  • Suitable for Kids and Adults - Take 4 capsules daily with or without a meal, or as directed by your healthcare professional.
  • Available in Two Formats - Mega IgG2000 can provide a dairy-free alternative to your usual colostrum supplement capsules and is available in either a powder or capsule form. Both are suitable for children ages two and up, and designed for daily use.

Evidence & sources

The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.

Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

How to read the Evidence dimension

  • 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
  • 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
  • 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
  • 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
  • 0–19: No credible evidence base or unverifiable claims.
