- Where are transfer factors found?
In the blood and in the first milk (colostrums) after a mother gives birth.
- What is colostrum?
Colostrum is the “first milk” that a mother produces immediately after giving birth.
- What prompted scientists to look for transfer factors in colostrum?
Through observation, it was noticed that when calves were not allowed to nurse, they often died within a short time—in spite of an abundance of food. Infection by common organisms was generally the cause. Research established that the mother was providing transfer factors to the offspring.
- What are advantages of using cow colostrum as a source for 4Life Transfer Factor®?
Transfer factors are not species specific, meaning they can transfer immunity to humans even if the original source is from a different species. Cattle have heroic immune systems, which allow them to survive in highly unsanitary conditions. These heroic immune systems produce potent forms of transfer factors.
