“Transfer factor is a science-based product with excellent data from a variety of researchers.”

“4Life has proven itself to be a company that provides sound dietary supplements, in keeping with the latest research. This committment to providing revolutionary natural products is one that I am excited to help develop. I am particularly struck with the potential that exists for the transfer factor. Transfer factor is today where vitamins and herbs were 15 years ago.”
