Immune4Life verifies product information through a source hierarchy: current official U.S. product pages and labels first, original research second, authoritative regulatory and public-health sources third, and customer or international sources only for context.

The purpose is to prevent outdated formulas, regional directions, copied claims, and overstated evidence from becoming permanent website content.

Source hierarchy

  1. Current official U.S. product page.
  2. Current U.S. package label.
  3. Official 4Life company and compliance pages.
  4. Original peer-reviewed research.
  5. FDA, FTC, NIH, and other authoritative sources.
  6. Independent reviews and community discussions for language research only.
  7. International and historical sites for topic discovery only.

Product verification checklist

Before publication, editors confirm:

  • exact product name;
  • current U.S. availability;
  • serving size;
  • directions;
  • active ingredients;
  • other ingredients;
  • milk and egg allergens;
  • package count;
  • source date;
  • current official link.

Claim verification

Each claim is classified as:

  • current official product claim;
  • independent scientific finding;
  • company-sponsored research finding;
  • editorial interpretation;
  • customer experience.

These categories should not be blended.

Research verification

The editor checks:

  • exact formulation;
  • study population or model;
  • dose;
  • duration;
  • comparator;
  • endpoint;
  • limitations;
  • funding and conflicts.

Use of Russian-language sources

Russian Transfer Factor sites can reveal:

  • historical products;
  • old terminology;
  • common questions;
  • regional practices.

They do not control U.S. formulas, directions, or claims.

Update dates

Product pages should be reviewed more frequently than general educational articles because formulas, prices, and availability change.

Corrections

A trustworthy correction process includes:

  • contact route;
  • review of the source;
  • correction date;
  • explanation when material;
  • no silent preservation of known errors.

The responsible conclusion

Immune4Life does not treat any single source as sufficient for every claim.

The website’s value depends on matching each statement to the correct current product, source, evidence level, and commercial disclosure.
