About 4Life

Founded in 1998 by David and Bianca Lisonbee, 4Life began with a clear mission: to make immune system support both accessible and effective through modern science. David discovered research on Transfer Factors, tiny molecules that help “educate” the immune system, and recognized their extraordinary potential. He licensed the technology and worked with leading scientists to develop it in supplement form. Inspired by Bianca’s passion for wellness and global impact, the couple took a leap of faith by mortgaging their home and building their first production facility from the ground up. What started as a breakthrough in scientific literature has grown into a worldwide mission: providing immune support that is rooted in nature and backed by science.

Responsible sourcing, manufacturing and farming practices

Sourcing from bovine colostrum

4Life sources its colostrum from animal friendly dairy farms around the United States. The colostrum is shipped to the 4Life manufacturing plant in Vineyard, Utah, where it is tested, filtered, and used in 4Life Transfer Factor products.

“Cows produce over 6-10 gallons of colostrum, which is far more than the calf will consume.† The calves take what they need … and then some, and then we only collect what’s left over,” said Lisonbee.

Once the calf has had all the colostrum it needs, several litres of excess colostrum get extracted, within 16 hours after birth. The colostrum is quickly frozen, to maintain the bio active components. It is then transported in refrigerated trucks to the processing facility in Utah. All containers are sanitized before and after use, to ensure safety and avoid contamination.

Responsible Farming

4Life partners with dairy farms all over the United States to harvest cow Colostrum. The majority of these farms are family-owned businesses and are “grade A” certified. All dairy farmers associated are in compliance with the pasteurized milk ordinance guidelines by the US FDA. Dr. Richard Bennett, a member of the 4life Health Sciences Advisory Board regularly visits the dairy farms to inspect the colostrum collection process and ensure the implementation of 4Life’s exacting standards of transfer factor production. Since 2023, 100% of 4Life Research’s sourcing farms are FARM certified. FARM stands for Farmers Assuring Responsible Management. This certification ensures that the farmers adhere to the highest standards for Animal care, environment, antibiotics, and biosecurity.

Sourcing from egg yolk

4Life Research also has patented processes to extract Transfer Factors from chicken egg yolk. Our poultry farms operate under the regulations and standards of the USDA. Under these standards, the chickens are not fed any hormones, and federal law requires that all egg products be pasteurized. Farm fresh eggs are transported to a partner processing facility. The eggs are cleaned and sanitized with quality control checks made throughout the process. High speed machines automatically break and separate shells, yolks and whites. Yolks are pasteurized, mixed and refrigerated. Once the egg yolk has gone through a similar filtering and drying process as the cow colostrum, the resulting pure Transfer Factors are ready to be shipped to 4Life’s manufacturing facility. Here the Transfer Factors from chicken egg yolks are blended with cow colostrum ones, to form 4Life’s proprietary Tri Factor.

Manufacturing process

Here you can see a short video about 4Life Research’s manufacturing facility outside Salt Lake City, USA.

When it arrives frozen, the colostrum is transferred to a stainless steel tank where it’s thawed, mixed and tested for quality. When the colostrum reaches the appropriate temperature, it is filtered to remove any impurities. Colostrum is ultra-filtered using a process that is patented and completely unique to 4Life. Non-essential elements like fat and lactose are then taken out of the colostrum, before it gets sterilized to eliminate any contamination. Any remaining liquid is removed from the mixture using a low heat, low-pressure, indirect steam drying process.

This preserves maximum bio-activity and maintains the integrity of Transfer Factor molecules. The result is pure, concentrated Transfer Factor, in a fine, free-flowing powder that can be processed into capsules (or drink solutions, chewing tablets etc).

The capsules are automatically packaged in clean containers, which are labelled, and finally secured with a tamper resistant seal. A lot code is applied to each product, to trace the product all the way through the manufacturing and distribution process.
