The Primary Benefit Is: Immune Support

Immune support involves helping the body's natural defences function normally through components derived from cow colostrum. This product provides a Transfer Factor Complex concentrated from fractionated bovine colostrum to support immune system health.

This form emphasises the transfer factor complex within fractionated colostrum as the active component, designed to support immune function and resilience in the body.

How Does This Support Immune Health?

Transfer Factor Complex helps maintain immune function and contributes to normal immune response, supporting the body's defence systems as part of routine hormonal and immune regulation.

In line with evidence on immune modulation, these factors are associated with supporting immune system integrity and lymphocyte activity, contributing to overall immune readiness.
