Hailey Bieber has a sneaky wellness trick that enhances her glow. . . and it's something she stirs into her coffee every morning. In a recent "day in the life" video posted on TikTok, the Rhode founder revealed that she keeps her morning routine simple and effective by making a latte at home. But instead of just adding a dash of milk, she mixes in Cowboy Colostrum for added benefits. What exactly is colostrum, though? This nutrient is produced by mammals immediately after giving birth and is meant to nourish their offspring.
