Is There an IgI Colostrum Supplement Not Derived from Bovine Blood Serum?

Question: I'm looking for an IgG supplement that is not derived from bovine blood serum. Is there such a thing?

IgG (immunoglobulin) supplements are highly popular this winter as consumers are discovering how really great they defend against all kinds of microscopic predators. For those who want an IgG supplement derived from something other than blood, we recommend colostrum, and our most potent product is item Swanson High Ig Colostrum,which has a 40% immunoglobulin content.

Check out all of our colostrum supplements.
