Transfer factors are nature’s immune wisdom, helping your body recognize, respond to, and remember potential health threats.*

Immune system support
Recognize

potential health threats.*

Recognize

Transfer factors carry important messages to immune cells and help them quickly identify invading threats.*

Respond

faster to those threats.*

Respond

Transfer factors help speed up the immune system’s response to a potential threat after it’s been identified.*

Remember

how to act when those threats return.*

Remember

Transfer factors lend a hand in remembering the specific makeup of the threats your immune system comes across, so the next time they're encountered, your body knows exactly what they are and how to combat them.*
