Give superior immune support a “tri!” This advanced formula helps your immune system recognize, respond to, and remember potential health threats, while offering more broad-based immune system support through a proprietary combination of 4Life Transfer Factor® (immune messenger molecules) from cow colostrum, OvoFactor® from chicken egg yolks, and NanoFactor® mini molecules. Recent independent laboratory studies show that 4Life Transfer Factor® Tri-Factor® Formula bolsters Natural Killer (NK) cell activity in the presence of a health threat, while activating a variety of other immune system cells, such as B cells and T cells.† Patents4Life Transfer Factor• 6,468,534 B1• 6,866,868 B1• 10,464,980 B1• 11,203,625 B1• 10,471,100• 11,197,894 1 Clinical study on the rapid immune modulating effects of 600 mg of 4Life Transfer Factor Blend compared to placebo.
