ARMRA Made A Colostrum Soda. Will Anyone Buy A Second 12-Pack?

It was probably only a matter of time before someone put colostrum in a can and gave it bubbles.

Colostrum, the nutrient-rich first milk mammals produce after giving birth, is often touted as "liquid gold" for the concentrated antibodies, proteins and other nutrients it delivers to newborns. Since drinking human breast milk as adults presumably felt too weird even for the wellness-obsessed— taint tanning notwithstanding—supplement makers did the next most logical thing: turned to cows.

Bovine colostrum has spent the past few years migrating from bodybuilding circles into expensive jars, single-serve sticks, and GRWM social media morning routines. Now, ARMRA , a physician-founded supplement brand best known for its bovine colostrum powders, has put it in a 12-ounce can and suggested we make it our afternoon treat.

Introduced in late April 2026, ARMRA Colostrum Soda comes in four flavors: Spicy Lime, Huckleberry, Pomelo Basil and Pear Ginger. Each sugar-free can contains one gram of ARMRA's bovine colostrum concentrate and retails for $3.99 at Sprouts ; a 12-pack is $49.99 online before shipping. ARMRA isn't asking customers to trade their jar of powder for a can of pop. The brand wants them to make room for both.

This can be a lucrative proposition. Functional soda has already shown that an ingredient story can create a new fridge favorite. PepsiCo paid $1.95 billion for prebiotic soda brand Poppi in 2025. ARMRA's bet is that colostrum can follow this perpetual path to personal optimization and go from niche supplement to cold, convenient beverage.

Asked what ARMRA expected the soda to compete with in the refrigerator, Sarah Rahal, MD, ARMRA's founder and CEO, is blunt: "Nothing, and that's not a dodge." The company's jarred colostrum powders fit the parts of the day that repeat—like a skincare routine or a morning cold plunge—while the can is meant for everything in between. "Discipline already had a product," she says. "Desire didn't."

It is tidy brand language, but it helps explain the opportunity: ARMRA is not merely adding colostrum to soda. It wants consumers to see colostrum itself as something they might crave, like an ice-cold Diet Coke.

This premise only works if the beverage in the can is enjoyable, with or without the liquid gold promise.

Out of curiosity—presumably because I was formula fed as a baby and wanted to know what I'd missed—I tried the sodas myself. The Pomelo Basil was easily my favorite; the basil note was satisfyingly assertive, while the pomelo tasted fresh and true rather than artificial. It was crisp and tart, like a refreshing Italian soda. The Pear Ginger was milder, but the ginger brought a fun hit of heat. Spicy Lime should appeal to fans of Mountain Dew or spicy margaritas, or, ideally, both. Huckleberry gave me the most pause. I'm not sure what a huckleberry is supposed to taste like, but I'm fairly certain I've never encountered a fruit that tastes like this soda. All four were properly fizzy, with a subtle creaminess to the texture.
