What are transfer factors?

They are small molecules (peptides) found naturally in colostrum —the first milk mothers give their young— and in egg yolk. 4Life concentrates them with its own filtration processes and offers them in capsules. They are not a vitamin, a mineral or an herb: 4Life describes them as support that “educates” immune cells.*

The three “R”s 4Life uses to explain how they work:
🔍 Recognize potential health threats.
⚡ Respond to them.
🧠 Remember them for next time.*
