PhytoFactor™ by 4Life — Plant-Based Transfer Factor Peptides

Discover the Power of Plant-Based Transfer Factor Peptides

Meet PhytoFactor™, 4Life's innovation in immune support. After decades of pioneering Transfer Factor science, 4Life has taken a major leap forward with the discovery of plant-based transfer factor peptides—naturally occurring immune messengers found in the seeds of Brassica napus.

Backed by research, supported by peer-reviewed publications, and protected by patents pending, PhytoFactor™ brings a modern, sustainable, and scientifically advanced approach to immune wellness.*

What Is PhytoFactor™?

PhytoFactor™ is a proprietary blend of plant-derived transfer factor peptides—small molecules that help educate your immune system, supporting its ability to recognize, respond, and adapt to everyday challenges.* Traditionally sourced from colostrum and egg yolk, transfer factors now have a plant-based origin thanks to 4Life's breakthrough discovery.

With PhytoFactor™, you get:

• Plant-based immune intelligence*

• Naturally occurring peptides from Brassica napus seeds

• Sustainable, renewable sourcing

• A vegetarian-friendly immune support option

• A next-generation extension of 4Life's Transfer Factor technology

Why PhytoFactor™ Matters

1. A New Era of Plant-Based Immune Support

PhytoFactor™ offers a clean, sustainable, plant-powered option with immune-educating activity comparable to traditional animal-based transfer factor sources.*

2. Supported by Real Science

4Life partnered with researchers to screen over 100 high-protein plants, identifying unique peptides capable of supporting immune function.* This research has been featured in scientific journals and is part of 4Life's long-term investment in evidence-based nutrition. Read more about the underlying science on our Transfer Factor Immune Science page.

3. Designed for Synergy

Rather than replacing traditional Transfer Factor, PhytoFactor™ is crafted to complement it. Combined, plant-based and animal-based transfer factors provide a broader range of immune support.*

4. Sustainability Without Compromise

As demand for plant-based options grows, PhytoFactor™ offers a way to support immunity without relying on animal-derived ingredients—an eco-friendly choice.*

How PhytoFactor™ Works

PhytoFactor™ interacts with immune cells by:

• Helping immune cells communicate more effectively*

• Supporting the body's natural ability to recognize potential threats*

• Supporting overall immune readiness*

• Promoting balanced, intelligent immune function*

These plant-based transfer factor peptides act like tiny messaging molecules—helping your immune system respond smarter, not louder.*
