The PhytoFactor™ Discovery

The biggest innovation in immune science in the last 70 years.

When Dr. H. Sherwood Lawrence first isolated transfer factors in 1949, he was looking inside white blood cells. For decades after, the field grew around two extraordinary sources: cow colostrum and chicken egg yolks. 4Life built an entire industry on getting them right.

Then 4Life Research asked a new question: what about plants?

The answer became PhytoFactor™ — bioactive immune peptides extracted from Brassica napus seeds. 4Life's first vegan source of transfer factor, and the only plant-based transfer factor in the world today.

And while animal-based transfer factors deliver immune information, PhytoFactor™ does something a little different: it has a more direct effect on invading organisms^ and activates the immune cells' response. Two mechanisms. One bottle. Transfer Factor Max.

^In preclinical studies. — 4Life Research

Founded 1998 · The Lisonbee Family

Since 1998. Family-built. Immune-obsessed.

4Life was founded in 1998 by David and Bianca Lisonbee, who saw something the rest of the supplement industry hadn't yet: that transfer factors — the tiny molecules your immune cells use to teach each other — could become a daily wellness ritual.

They started in a small office in Sandy, Utah, with a single product and one obsession: educating, equipping, and empowering immune systems. Twenty-five years later, that same focus runs through every product 4Life makes — including Transfer Factor Max.

The company is still family-led, still immune-obsessed, and still asking the same question David and Bianca asked at the founding: what else can we teach the immune system?

Questions · Answered

Everything you want to know, before you order.

How do I take Transfer Factor Max?

Take four (4) vegetable capsules daily with 240 ml (8 oz) of water. For best results, take with food. One bottle contains 30 servings (120 capsules) — a one-month supply.

What's actually in a serving?

The headline number is 900 mg — the total 4Life Transfer Factor content per daily serving. The interesting part is where it comes from: two-thirds from the animal-based Tri-Factor® blend (colostrum + egg peptides) and one-third from PhytoFactor™, the first plant-based transfer factor ever commercialized. The supporting cast is what makes it "clinical strength" — a clinical dose of IP-6, a Super-Mushroom Blend of four functional mushrooms, and a targeted micronutrient cluster (Vitamin C, high-potency Vitamin D3, and Zinc at 90% of the daily value).

Is Max vegan or vegetarian?

Max is not vegan — it contains animal-based transfer factors from cow colostrum and chicken egg yolks, which are central to the formula. PhytoFactor™ itself is 4Life's first vegan source of transfer factor, but it's blended with the animal-based peptides inside Max. Capsule shells are vegetable-based.

How soon will I notice something?

Max is clinically proven to activate the immune system within two hours of your first serving.* Many customers describe feeling the clearest difference after several weeks of consistent daily use.

What clinical research backs Max?

Three clinical studies: a 2024 feasibility trial published in Current Issues in Molecular Biology (Yu et al.) on rapid immune activation, a 2026 4Life technical white paper on stem cell mobility, and a 2026 clinical report on neutrophil activation. Plus thousands of published studies on its individual ingredients.

Can I stack Max with other 4Life products?

Yes. Max is designed as a foundation and pairs well with RioVida®, the rest of the Transfer Factor line, and 4Life's targeted formulas. Check with your healthcare provider if you're on immunosuppressive therapy.

Pregnancy, breastfeeding, or kids?

Please consult your physician. Max is formulated for adults.

Where is Max made?

In 4Life's NSF and cGMP-certified manufacturing facility. Non-GMO. Every batch is rigorously tested.
