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. Yep — even humans produce it! Colostrum from cows, specifically, has recently made a major splash in the wellness world, as it has been shown to help boost immunity, improve gut health, leave skin glowing and result in longer, thicker, stronger hair.

I have a sneaky suspicion that Bieber’s glazed donut-level glow isn’t only because of her milky Rhode formulas. Cowboy Colostrum definitely plays an important role because it works from the inside out.

Incorporating colostrum into your routine really is as easy as mixing it into your morning coffee, like Bieber demonstrates. However, because the Cowboy Colostrum version comes in a range of flavors — including vanilla and chocolate — you can also mix it into your morning oatmeal, protein shakes and more. If you aren’t a fan of something slightly sweet, the same product is also available in an unflavored version, which is easy to add to water and smoothies.

Like many wellness trends, colostrum has garnered some skepticism, but Amazon shoppers who have tested this pick call it their “secret weapon” for energy, hair growth, recovery and immunity.

“I never thought I’d be raving about cow colostrum, but Cowboy Colostrum powder has completely won me over,” one reviewer wrote. “I’ve been having it daily mixed into a glass of milk for a couple months now, and the difference in my energy, digestion, hair health/growth and overall well-being is undeniable. It’s rare I find a supplement that actually lives up to the hype, but this one absolutely does. It’s become a non-negotiable part of my daily routine.”

This all-in-one Cowboy Colostrum simplifies your wellness routine and can replace a variety of supplements. You might just be able to ditch all of your rogue vitamins and minerals in favor of the powder — but you’ll never know unless you give it a try.
