4Life's most advanced immune formula — 900 mg of peptides from plant, colostrum & egg, powered by PhytoFactor™ and IP-6. The first formula to unlock Repair.
Max brings together all four types of 4Life Transfer Factor and adds two firsts: plant-based PhytoFactor™ and IP-6.
The first-ever plant-based transfer factor — from the seeds of Brassica napus.
Inositol hexaphosphate joins the formula to broaden Max's immune support.
Plant, cow colostrum, and chicken egg — the broadest peptide blend 4Life makes.
Supports the broadest range of immune cell types of any 4Life formula.1Breadth of immune cell types supported, per 4Life clinical white paper (Gardner et al., 2026).
For decades, transfer factor came from two animal sources. Max adds a third — and it changes everything.
Immune information a hen passes to her chicks through the yolk.
The immune-rich first milk a mother passes to her newborn calf.
From the seeds of Brassica napus — the world's first vegan transfer factor.
For 70 years, transfer factor meant colostrum and egg. Then 4Life found the same kind of immune messengers in an unexpected place — the seeds of Brassica napus.
The result is PhytoFactor™: the world's first-ever source of vegan 4Life Transfer Factor. It broadens the immune education your body can borrow — and it's only in Transfer Factor Max.
Evolution, in one line: egg → colostrum → plant. The same idea, taken further than ever.

Classic transfer factor helps your immune system recognize, respond, and remember. Max adds a fourth: it's clinically shown to mobilize stem cells for targeted repair2Clinically shown to mobilize stem cells for targeted repair — 4Life clinical report (Jensen et al., 2026). — a first for the category.
