What does “bioactive” mean as applied to whey and colostrum?
Bioactivity [bahy-oh-ak-tiv-i-tee] refers to any nutrient that has an effect on, or creates a response from, living tissue. Such a nutrient is called bio-active. Undenatured whey and colostrum have many bioactive peptides and proteins. Some, like immune globulins, confer passive immunity. Others, like PRPs, actively modulate (balance) immune function.
