- Is there any information about the safety of transfer factors?
In 1980, the FDA approved the use of bovine colostrum, which was then followed by the approval of bovine transfer factor for human use in 1985. Throughout its use, there have been no reports of adverse reactions, even when clinically administered in excess or when normal doses have been given over many years.
