Take a look a a product called TransferFactor Plus, from a company called 4Life Products.

The knowledge about the immune properties of colostrum - the first milk from the mother after the baby has been born - has been around for years if not decades.

It appears that chicken egg yolks have these amazing immune properties as well. It's these egg-yolk immune properties that have been transferred from chicken eggs to TransferFactor Plus.

Now, there are probably at least a few other companies out there that have done something similar to what 4Life Products has done. See if you can find them, because all these products are worth it, enhancing the immune systems of everyone who uses them.
