One popular brand boasts the supplement can ‘revive whole body health’. But can an aesthetically packaged powder actually achieve that?

Wellness influencers have a new obsession: bovine colostrum. Goop and Poosh (Kourtney Kardashian’s version of Goop) have covered it, and celebrities Sophia Richie and the Kid Laroi include it in their signature Erewhon smoothies .

But what is it? Colostrum is a form of milk that mammals produce in the days after they give birth. What does this mean for the body? According to one popular brand , their bovine colostrum supplement can “strengthen your skin, lung and gut barriers, rebuild your microbiome, and activate cellular health and performance to revive whole body health”.
