What is Transfer Factor?
Tap on the topics below to view detailed information
Overview
Immune system education starts with a mother and a nursing baby. When babies are first born, they have underdeveloped immune systems. When a baby is fed colostrum or “mother’s first milk,” the mother transfers immune knowledge to her baby. This is called “passive immunity” because the mother is “passing” or “transferring” her immunity to her child. The passive immunity helps educate the baby’s inexperienced immune system.
Colostrum is especially rich in proteins that can be transferred from one immune system to another—and from one mammal to another. One type of protein discovered in colostrum is called transfer factor. 4Life Transfer Factor is sourced from cow colostrum and chicken egg yolks. Through innovation, 4Life harnesses transfer factor proteins from these sources to create a product that offers continuing immune system education for you and your family.

Transfer Factor is known to be the only supplement in the world made by the immune system for the immune system. Transfer Factor molecules are completely unique, they contain information that can be transferred from one immune system to another. What it does is it educates, enhances, and balances the immune system which causes a positive domino effect on the entire human body.
How it works
4Life Transfer Factor has three main functions. First, it educates or teaches the immune system cells to recognize different threats or abnormalities inside the body.
Educates
• Help immune cells quickly recognize foreign invaders or other potential threats
• Help the immune system respond more efficiently after an invader has been identified
• Lend a hand in remembering how to tackle each problem your immune system encounters, so your body knows exactly what to do next time
Boosts
Second, it helps stimulate the activity of the immune cells responsible to fight invaders and threats.
Balances
Third, it helps balance the immune system when it is over reactive, a condition wherein good cells fight other good cells due to immune system error.
Technical Description
Transfer factors are proteins and peptides that communicate antigenic immunological information intercellularly between a donor and a recipient. These molecules are polypeptides that consist of 40 to 44 amino acids and are thought to have a conserved region and a variable region. Only Transfer factor molecules that have a molecular weight of less than 3,500 daltons are capable of modulating an immune response.

History
In 1949, Dr. H. Sherwood Lawrence, a New York University researcher and Immunologist, made a very significant discovery that immune information is transferable from one specie to another. The strange molecules attached to the immune cells were the one responsible for transferring of immunity, and so he called them Transfer Factors.
Babies that were not breast-fed during the first three days of birth are more prone to immune invaders. These led to the discovery of Transfer Factors in the first three days of milk called “Colostrum”. In cows, its found within the first five days or first 9 gallons of milk. Chicken egg yolk also contained similar Transfer Factor molecules. After testing these molecules were found to be similar in structure and are non-species specific, meaning they can be transferred from humans to animals and vice-versa. They carry immunity codes or antibodies transferred from mother to baby, which helps the young offspring survive the first six months of life.
4Life Research was at the forefront and hundreds of scientists were challenged to find Transfer Factor in other sources. US$ 42 Million was spent on research.
Through a patented filtration process, 4Life extracts transfer factors from cow colostrum and chicken egg yolks for the foundation of its Transferceutical products. People of all ages can benefit from nature’s first supplement by borrowing immune memory from the strong immune systems of these two animals.
Studies and Patents
Scientists around the world have conducted numerous studies to research the effectiveness of transfer factor molecules. 4Life scientists have continued this legacy by commissioning third-party studies and in-house scientific tests to understand just how well 4Life Transfer Factor products interact with specific immune cells.
Patents reinforce 4Life’s credibility in the wellness industry and demonstrate the company’s long-term commitment to exclusivity and stability. We have currently have 17 US patents, 65 International patents and dozens more pending.
