Transfer factor was discovered in 1949. 4Life brought it to the world in 1998 — and has spent 28 years compounding the science, the patents, and the results ever since.
Where transfer factor came from, what makes it different, and where the science is going next. Pick an episode — or watch them in order.
How a doctor at NYU discovered a class of immune molecules nobody knew existed — and named them transfer factors.
From the moment a transfer factor capsule enters the body — follow its course through digestion, delivery, and the immune cells it speaks to.
The world's first plant-based transfer factor. A new chemistry for vegan, vegetarian, and plant-first lives — without giving up the immune-education science.
Five reasons the flagship Tri-Factor formula has become the gold standard for clinical-strength immune support — and why most users start here.
From a discovery at NYU to a patented category. Here's the short history of transfer factor — and the company that commercialized it.
Dr. H. Sherwood Lawrence at NYU School of Medicine identifies transfer factors — naturally occurring polypeptides that carry immune information between organisms. A new category of immunology is established.
Transfer factors are studied extensively in academic and clinical settings. Thousands of peer-reviewed papers accumulate across universities, hospitals, and research institutions — establishing the rigor the category now stands on.
David and Bianca Lisonbee found 4Life Research and launch the first commercial transfer factor product — sourced from bovine colostrum — transforming a clinical niche into an accessible wellness category.
4Life pioneers the extraction of transfer factors from chicken egg yolks, broadening the immune-information footprint and unlocking new formulation possibilities.
The U.S. Patent on 4Life's proprietary extraction and concentration process makes the category defensible. Competitors can't legally replicate what 4Life makes — a moat that still protects the business today.
4Life launches the world's first formulation combining bovine and avian transfer factors in a single product — delivering complementary immune information that no other company can match.
4Life expands to 50+ countries and crosses billions in lifetime commissions. Manufacturing, research, and distribution infrastructure mature into a truly vertically integrated business.
Peptides become the trend of the decade. For 4Life, it's nothing new — transfer factors are naturally occurring polypeptides, and the company has been delivering immune peptides since 1998. The broader market finally catches up. The portfolio keeps expanding.
4Life launches the world's first plant-based transfer factor. A scientific breakthrough that opens vegan, vegetarian, and plant-first markets previously beyond reach — and proves the science is still just getting started.
For 75 years, transfer factor came from one place: animals. Cow colostrum. Chicken egg yolks. The science worked, the patents held, and millions of people benefited. But a whole population — plant-first, vegan, vegetarian — was outside the door.
PhytoFactor changes that. The world's first plant-based transfer factor — a new peptide chemistry derived from carefully selected botanicals, engineered to deliver the same immune-educating signals through a completely different source.
Three things separate a defensible science business from a me-too supplement line. 4Life is built on all three.
U.S. patents cover the Transfer Factor E-XF extraction process. The molecules, the concentration method, the formulation — all proprietary. When you share 4Life, you're sharing something no competitor can legally make.
Decades of peer-reviewed publications, clinical partnerships, and an active Scientific Advisory Board. 4Life has built a research record the way pharmaceutical companies do — patiently, over years.
4Life owns its intellectual property, its extraction processes, and its manufacturing facility. From molecule to bottle, nothing is outsourced — which is why the supply chain has never disrupted a commission cycle.
Most wellness brands are marketing companies with an overseas co-packer. 4Life isn't. We own our manufacturing in Utah and produce our own products from start to finish.
It's a harder, slower, more expensive way to run a wellness company. It's also the reason the product on your customer's counter is the same product the scientists designed — and the reason commissions have never missed a cycle in 28 years.
Raw material sourcing, extraction, blending, encapsulation, and packaging — all owned and operated by 4Life in Utah.
Good Manufacturing Practices certification ensures pharmaceutical-grade process control and documentation.
Every batch is tested in-house for identity, potency, and purity before it ever leaves the building.
The same Utah-made product ships to customers in 50+ countries — one standard, everywhere.
Transfer Factor — the original natural immune peptide. PhytoFactor — the world's first plant-based transfer factor. 28 years of naturally occurring peptide leadership, and the roadmap keeps expanding.
Transfer factors are naturally occurring polypeptides — small protein chains that carry immune information. 4Life extracts them from bovine colostrum and avian egg yolk with a patented process no competitor can legally replicate. The anchor product that built the company and still anchors the affiliate line today.
Transfer factors are naturally occurring polypeptides — and 4Life has been delivering immune peptides since 1998. While the wellness industry is just discovering the category, 4Life has 28 years of research, patents, and real-world results behind it.
A scientific breakthrough and a commercial one. PhytoFactor opens vegan, vegetarian, and plant-first markets that Transfer Factor couldn't fully serve — and 4Life is first to it.
When products actually work, customers come back. When patents protect them, competitors stay out. When a company owns its science, it controls its future — and yours.
A product line competitors can't legally replicate is a product line customers can't easily leave.
A peer-reviewed record makes the pitch easy and the belief real — for you and the people you share with.
Owned manufacturing means products ship, commissions pay, and your business never waits on someone else's factory.
From 1949 to PhytoFactor, the story keeps unfolding. Your product line stays fresh because 4Life keeps inventing.
