The evolution of immune peptides

From the barn… to the garden.

For decades, transfer factor came from two animal sources. Max adds a third — and it changes everything.

Chicken egg

Immune information a hen passes to her chicks through the yolk.

Source 2 · Ultra/NanoFactor®

Cow colostrum

The immune-rich first milk a mother passes to her newborn calf.

Source 3 · PhytoFactor™

Plant seed

From the seeds of Brassica napus — the world's first vegan transfer factor.

🌱 The plant breakthrough

PhytoFactor™: immune wisdom, grown from a seed.

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.
