Frequently Asked Questions About 4Life Research
What are 4Life Transfer Factor products?
4Life's flagship products are Transfer Factor supplements — proprietary extracts from cow colostrum and egg yolks claimed to support immune system function. The technology is patented. However, FDA has not evaluated these claims, and independent clinical evidence is limited.
Is 4Life a legitimate MLM?
4Life is a legitimate MLM company with 26 years in business and real products. However, like most MLMs, the income opportunity is challenging — most distributors earn minimal income after accounting for required monthly product purchases.
How much do 4Life distributors earn?
4Life has an income disclosure but specific average earnings data varies by rank. TINA.org audited 4Life's income claims in 2024 for FTC compliance. As with most MLMs, the vast majority of active distributors earn less than their monthly product purchase requirements.
