You want your family protected. Not just today, but for years to come 🌱
That desire isn’t new. Our founder David Lisonbee felt it too.
He was a husband and father who found groundbreaking research about immune health and couldn’t let it go. In 1998, he started 4Life Research from his living room with one goal: bring that discovery to families who needed it most.
He understood what you’re looking for, because he was looking for it too.
That’s why for 70+ years, 4Life has never stopped developing solutions:
✅ 1998 — 4Life Transfer Factor Classic, made from cow colostrum
✅ Transfer Factor Plus — the next step forward
✅ OvoFactor — sourced from egg yolk
✅ NanoFactor + the Tri-Factor Formula
✅ PhytoFactor — the first plant-based transfer factor
✅ NOW: 4Life Transfer Factor MAX — combining plant-based PhytoFactor, the Tri-Factor Formula, and other immune nutrients
Today, that same mission is in your hands, and 4Life keeps innovating to bring you the best in science 💪🏼
