Kourtney Kardashian Barker is the latest celeb to capitalize on the craze: Her wellness brand, Lemme, has introduced a new line of colostrum gummies purported to support gut health, promote healthy digestion, manage bloating, and enhance “full-body wellness.” If you’re stuck on the fact that colostrum is a precursor to breast milk, let’s clear something up (and hopefully put your mind at ease in the process): You’re not ingesting a human bodily fluid when you take a colostrum supplement. While mammals of all kinds (humans included) produce colostrum to meet the nutritional and developmental demands of their offspring, the stuff you see in commercial products is bovine colostrum—colostrum that comes from cows.
