Transfer Factor Max is 4Life's most advanced immune-support formula. Each daily serving delivers 900 mg of 4Life Transfer Factor — including 600 mg of the Tri-Factor Blend (UltraFactor XF®, NanoFactor®, OvoFactor®) and 300 mg of plant-based PhytoFactor™ — plus IP-6, a Super-Mushroom Blend, vitamins C and D3, zinc, oats, and baker's yeast. For the full panel with the actual amounts — including which figures 4Life discloses exactly and which sit inside the 843 mg Cordyvant™ proprietary blend — see every ingredient in Transfer Factor Max, dose by dose.

Take four (4) vegetable capsules daily with 8 oz of water. For best results, take with food. One bottle is a 30-day supply (120 capsules · 30 servings). For the longer answer — morning versus night, what kind of meal, whether you can split the four capsules, and what to do about a missed day — see our guide to when to take Transfer Factor Max.

Max contains everything Tri-Factor did, plus: PhytoFactor™ (the new plant-based transfer factor), a clinical dose of IP-6, the four-mushroom Super-Mushroom Blend, and supporting vitamins (C, D3, zinc) and polysaccharides (oats, baker's yeast). See our Why Max page for a side-by-side comparison.

Clinically, immune activation begins within two hours of the first serving.* Subjective effects vary by individual — most customers report noticing the clearest difference after several weeks of consistent daily use.

No. The capsule shell is vegetable-based, but the formula contains animal-derived peptides from cow colostrum and chicken egg yolks. PhytoFactor™ itself is 4Life's first vegan source of transfer factor — if you need fully vegan options, 4Life Super Greens and 4Life Immune Tea both contain PhytoFactor™ without the animal-based ingredients.

No — and it isn't designed to. Max includes vitamin C, high-potency vitamin D3, and zinc at 90% DV, but not the broad vitamin and mineral spectrum of a multivitamin, and no greens, probiotics, or digestive enzymes. If you're weighing Max against a daily greens powder, we compared it directly to the most popular one: Transfer Factor Max vs AG1 — an honest comparison, including who should buy AG1 instead. Weighing it against a cheap vitamin C drink mix instead? See Transfer Factor Max vs Emergen-C. And if you're comparing it to a premium daily multivitamin like Ritual, read Transfer Factor Max vs Ritual — note Ritual's Essential formula contains no vitamin C.*

The manufacturer does not list specific side effects on the product label. Individual responses can vary. Consult your healthcare provider before starting, especially if you have a medical condition or take medication. For a full ingredient-by-ingredient walkthrough — including the milk and egg allergens in the formula and the medication classes worth asking about — see our guide to Transfer Factor Max side effects, safety and drug interactions.

Generally yes. Max pairs well with other 4Life Transfer Factor products and most common supplements. If you take many supplements or are on prescription medication, check with your pharmacist or healthcare provider.

Consult your physician. Max is formulated for adults — 4Life publishes no minimum age for it. For children, 4Life labels three separate transfer factor products by age; we compare all four side by side in Can Kids Take Transfer Factor Max?
