Transfer Factor Core Products: The Complete Line-Up

Every core 4Life Transfer Factor® formula, what makes each different, and who each one fits.

The core line at a glance

4Life's core immune products all share the same foundation — Transfer Factor® peptides that help educate your immune system to recognize, respond, remember, and repair.* They differ in concentration, added ingredients, and delivery format.

Transfer Factor® Classic

The original single-source formula — colostrum-derived transfer factors only. The right starting point for purists and first-timers who want the foundational product.*

Transfer Factor® Tri-Factor®

The modern everyday standard: UltraFactor®, OvoFactor®, and NanoFactor® combined. Daily immune education in its most balanced form.*

Transfer Factor Plus®

The best seller. Tri-Factor® Formula plus a Cordyvant™ blend of mushrooms and botanicals (maitake, shiitake, cordyceps, beta-glucans and more) for the most robust everyday immune support in the line.*

Transfer Factor® Max

The newest flagship — now formulated with 300 mg of plant-based PhytoFactor™ alongside Tri-Factor®, plus zinc and vitamin C.* See how it compares in Plus vs Max vs Tri-Factor.

RioVida® — the drinkable option

Tri-Factor® Formula in an antioxidant superfruit juice (açai, pomegranate, elderberry, blueberry). Also available as Burst gel packs, Chews, and Stix.

Transfer Factor® Chewable and Immune Sprays

Tablet-free formats — chewables for those who dislike capsules, sprays for on-the-go support.* A practical choice for families; kids and teens also have RiteStart® Kids & Teens.

How to choose

A simple rule of thumb: Classic for the original, Tri-Factor® for daily maintenance, Plus for maximum everyday support, Max for the newest science, RioVida® if you prefer drinking to swallowing capsules.* For a deeper walkthrough, read How to Choose the Right 4Life Product or the full side-by-side comparison.
