The PhytoFactor family: three formats, one ingredient

PhytoFactor™ is 4Life Research’s trade name for a plant-based source of the immune-supporting proteins and peptides the company markets as 4Life Transfer Factor®, obtained from the seeds of Brassica napus and sourced from Canada. It appears in three products, and only three: 4Life Transfer Factor Max, 4Life Super Greens and 4Life Immune Tea. 4Life prelaunched all three at its 2026 convention and made them available on July 1, 2026, describing PhytoFactor in the same announcement as the biggest transfer factor breakthrough in seventy years.

Most writing about this range treats it as a tiering exercise — the strong one, the daily one, the gentle one — and invites you to buy up the ladder. That framing is wrong in a way that costs the reader real information. These are not three strengths of one product. They are one declared ingredient placed into three formats that differ in what they disclose, how long a package lasts, who the label says may use it, and what has been studied.

The useful thing about a product family is rarely the overlap. It is the boundary: knowing exactly what is in the set, what is outside it, and which questions each member of the set can and cannot answer. That is what this page is for.

What PhytoFactor is, in one paragraph

4Life describes PhytoFactor as bioactive immune proteins and peptides derived from Brassica napus seeds — the species most people know as rapeseed or canola, a member of the cabbage and mustard family. It is the company’s first vegan source of 4Life Transfer Factor, sitting alongside three animal-derived sources it has used for years: UltraFactor® from ultrafiltered cow colostrum, NanoFactor® from nanofiltered cow colostrum, and OvoFactor® from chicken egg yolk. If you want the molecule rather than the product line, our explainer on what PhytoFactor is and the account of how 4Life came to work with Brassica napus cover that ground; this page stays on the shelf rather than in the laboratory.

The three formats, side by side

Everything in the table below is taken from 4Life’s own published product information. The column that repays the most attention is the third one, because it is the column where the three products stop being parallel.

Transfer Factor Max is the only one of the three that is a supplement in the conventional sense: a capsule, taken to a schedule, with a bottle that lasts a calendar month. It is also the only one carrying the rest of the formula — zinc at 90% of the daily value, vitamins C and D, IP-6, oats, baker’s yeast and the four fungi of the Super-Mushroom Blend. PhytoFactor is one ingredient among many in it.

Super Greens is a food-format beverage that happens to declare PhytoFactor. The bulk of the stick pack is greens, grains and roots — alfalfa sprouts, kale, spinach, broccoli, spirulina, chlorella, bell pepper, Italian parsley, pumpkin seed, rosehips, cocoa, flaxseed, quinoa, astragalus, beet, carrot, sweet potato — with inulin as a prebiotic fibre. Our piece on how Super Greens delivers 300 mg in a stick pack goes into the format question properly.

Immune Tea is the outlier, and deliberately so. It is a ritual object rather than a dose: caffeine-free, six organic botanicals — elderberry, ginger, astragalus root, rosehips, hibiscus and lemon peel — 35 mg of vitamin C per serving, sweetened with organic honey flavour and stevia, and the only product in the family that 4Life says is suitable for ages six and up. Our botanical-by-botanical guide to Immune Tea takes the ingredient list apart.

The number only one of them publishes

Here is the finding that made this page worth writing, and it is the kind of thing that only turns up when you read three product pages next to each other rather than one at a time.

The three products disclose PhytoFactor in three different ways. Super Greens states the amount outright: 300 mg per stick pack, in 4Life’s own feature list, alongside the claim that it is the only plant-based greens beverage in the world containing it. Transfer Factor Max publishes a combined figure — 900 mg of 4Life Transfer Factor per four-capsule serving — drawn from all four sources together, with PhytoFactor named as one of them. Immune Tea confirms that PhytoFactor is in the formula and does not publish a milligram figure at all.

Three consequences follow, and all three are practical.

The first is that you cannot add these numbers up. A reader who drinks a stick pack and takes four capsules has not consumed 1,200 mg of anything coherent; one figure counts a single source and the other counts four. The second is that you cannot compare the tea to either of the others on this axis, because the tea has no number on that axis. The third, and the one worth sitting with, is that the absence is not evidence of a small amount. It is simply an absence. Reading a missing number as a hidden number is a habit that gets supplement buyers into trouble in both directions.

This page could estimate the tea’s PhytoFactor content by analogy with Super Greens. It will not, because that estimate would be a fabrication with a plausible surface, and this site would rather leave a hole in a table than fill one in with an invention.

Why a plant source exists at all

A reasonable question sits underneath the whole family: 4Life already had three transfer factor sources that worked commercially. Why go looking for a fourth in a seed?

4Life’s own stated reasoning is the most interesting sentence the company has published about the ingredient, and it is worth quoting closely. Plants, it points out, cannot run away from threats the way animals can. That constraint gives them what 4Life calls a “stand and defend” form of immunity — a defensive biology shaped by having nowhere to go, and therefore different in kind from the immunity of an organism that can flee.

Whatever one concludes about the product, that is a genuinely different argument from the one usually made for a vegan alternative. The standard case for a plant-derived version of an animal-derived ingredient is substitution: same benefit, fewer objections, often lower cost. The case 4Life makes is addition — that plant immune material is not a stand-in for colostrum and egg but another category of material altogether, which is why Transfer Factor Max carries all four sources rather than swapping one for another.

It is a claim about biology, and like every claim about biology it is worth holding at the distance the evidence supports. But it explains the shape of the family. Super Greens and Immune Tea carry PhytoFactor alone and are vegan; Max carries PhytoFactor plus the three animal sources and is not. If PhytoFactor were simply a substitute, that arrangement would make no sense.

What is not in the family

This is the section most likely to save somebody money, and it is the one no competing page writes.

4Life has sold transfer factor products since 1998 and the catalogue is long. Transfer Factor Classic, Transfer Factor Tri-Factor®, Transfer Factor Plus® Tri-Factor Formula, Transfer Factor Chewable, RioVida® and the various targeted formulas all contain transfer factor. None of them contains PhytoFactor. Their transfer factor comes from the colostrum and egg-yolk sources — UltraFactor, NanoFactor, OvoFactor — in various combinations. In 4Life’s own product comparison, PhytoFactor appears in exactly one capsule product, and that product is Max.

So the two phrases circulating online are not interchangeable:

• A 4Life transfer factor product is a large set, most of it predating 2026, all of it animal-sourced.
• A PhytoFactor product is a set of three, all of them launched on the same day in July 2026.

Anyone shopping specifically for the plant-based ingredient — because they are vegan, because they avoid dairy or egg, or simply because they read about it and want that — needs the second list, not the first. Buying a well-reviewed older transfer factor product in the belief that it contains PhytoFactor is an easy and entirely avoidable mistake. Our primer on transfer factor sets out the wider category, and the pieces on colostrum and UltraFactor and OvoFactor cover the animal sources that the rest of the catalogue runs on.

What the family does not claim

Three products sharing one declared ingredient creates a specific temptation, and it is worth naming before someone else exploits it: the temptation to let evidence migrate.

The published research associated with this range sits on the Transfer Factor Max formula — the 2024 feasibility trial by Yu and colleagues in Current Issues in Molecular Biology, together with two 2026 company reports. Those studies examined a finished capsule formulation with a specific composition. They are not studies of a greens beverage, and they are not studies of a tea. Our plain-English guide to the three studies sets out what each one measured and on what.

A shared ingredient does not carry a result across a product line. This is not a technicality; it is the whole logic of testing finished products rather than ingredient lists. Dose differs, format differs, matrix differs, and what a person actually absorbs from a capsule taken with food is not established to be what they absorb from a hot infusion. Anyone who tells you that Immune Tea is “clinically proven” because Max was studied has made a claim that no published document supports.*

Nor does this page claim that the three products are equivalent, interchangeable or additive, that more formats produce more effect, or that any of them affects any disease, symptom or laboratory value.* They are dietary supplements. Each has its own label, and the label is the instruction. If you want the practical question of how to fit more than one of them into an ordinary day, our piece on building a daily PhytoFactor ritual handles it as habit architecture rather than pharmacology.

The shape of the thing

One ingredient. Three formats: a capsule built for a month, a beverage built for nutrition, a tea built for a ritual and cleared for children. One number published, one number pooled, one number withheld. One research base, attached to one of the three.

That is the honest map of the PhytoFactor family as 4Life publishes it in September 2026. It is less tidy than a three-tier ladder, and considerably more useful — because the gaps in it are real, and a reader who knows where the gaps are is better equipped than one who has been handed a diagram with no gaps at all.
