Scientists around the world have conducted numerous studies to research the effectiveness of transfer factor molecules. 4Life scientists have continued this legacy by commissioning third-party studies and in-house scientific tests to understand just how well 4Life Transfer Factor® products interact with specific immune cells.

One test shows that 4Life Transfer Factor products can increase the immune system effectiveness of Natural Killer cells (important first responders) by up to 437%.

Another preliminary scientific test suggests that 4Life Transfer Factor® Tri-Factor® Formula strengthens your immune system guard by increasing the number of protective salivary IgA antibodies by up to 73%. And, everyone tested experienced an increase!

4Life’s progressive science and pursuit of patent protection strengthen the business opportunity by giving 4Life distributors the exclusive right to market 4Life Transfer Factor products. Patents reinforce 4Life’s credibility in the wellness industry and demonstrate the company’s long-term commitment to exclusivity and stability.
