Quality and Labs

Many of 4Life products undergo hundreds of analytical tests before being released for distribution. Extensive testing ensures that each specification is evaluated and reported to maintain quality throughout a product’s lifecycle. To certify each 4Life Transfer Factor product, 4Life spent over one million dollars on state-of-the-art laboratory equipment to create one of the most advanced analytical labs in the direct selling industry.

4Life runs its own manufacturing facility and oversees each step of the manufacturing process. This includes, but is not limited to, batching, blending, encapsulating, and packaging.
