Raise Your Immune I.Q.

4Life Transfer Factor Classic has been recognized for years as the best colostrum-based Transfer Factor product for daily immune system support. It contains our original Transfer Factor XF® ingredient for safe and proven immune support.
What makes this product unique?

Transfer factors are tiny messenger molecules that transmit immunity information from one entity to another, such as between a mother and her breastfeeding infant.
• In an independent study, 4Life Transfer Factor Classic increased the Natural Killer (NK) cell activity 204 percent above normal immune response. Natural Killer cells are on the front lines of your immune system.
