Can ARMRA Sell A Second 12-Pack Of Colostrum Soda?

It was probably only a matter of time before colostrum ended up in a can with bubbles. The first milk mammals produce after birth has long been called “liquid gold,” packed with antibodies, proteins and other nutrients. Bovine colostrum has spent the past few years moving out of bodybuilding circles and into premium supplement jars, single-serve sticks and social-media morning routines. Now ARMRA, a physician-founded brand best known for its colostrum powders, wants to give the ingredient a spot in the beverage aisle.

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

The timing is reasonable. Functional sodas have already become a hot category, and the 2025 Poppi deal—PepsiCo paid $1.95 billion for the prebiotic soda brand—gave the whole aisle a jolt. The promise of a drink that tastes like a treat while doing something functional is now a proven retail template. ARMRA’s bet is that colostrum can follow the same arc, moving from niche supplement to cold, convenient beverage.

Sarah Rahal, MD, ARMRA’s founder and CEO, is clear about what the soda should compete with. “Nothing, and that’s not a dodge.” The company’s powders, she says, are for the repetitive parts of a day—like a skincare routine or a morning cold plunge. The can is for everything in between. “Discipline already had a product,” she says. “Desire didn’t.” It is tidy brand language, but it also explains the opportunity: ARMRA isn’t just adding colostrum to soda. It wants people to feel the same pull toward colostrum that they might feel toward an ice-cold Diet Coke.

Whether that works depends on the drink itself. I tried all four flavors. Pomelo Basil was the best of the bunch; the basil note was assertive and the pomelo tasted fresh rather than artificial. It was crisp and tart, closer to an Italian soda than a typical wellness drink. Pear Ginger was softer, with a pleasant heat from the ginger. Spicy Lime should appeal to fans of Mountain Dew or spicy margaritas—or, ideally, both. Huckleberry was the one that gave me pause. I’m not sure what a huckleberry is supposed to taste like, but I’m fairly certain it isn’t this. All four were properly fizzy and had a subtle creaminess in the texture.

That texture did not come easily. Rahal describes ARMRA’s unflavored powder as “mild and biscuity, closer to a shortbread than to anything sweet or sour.” In flat water, it works. Carbonation changes the equation. “Acid and bubbles pull any tang forward, so instead of hiding it under fruit, we built each flavor to sit alongside it,” she says. Mouthfeel was harder. “Colostrum is protein-forward, and protein in an acidic, carbonated system doesn’t always stay smooth; it can turn thin or slightly chalky if you don’t manage it correctly.” The company spent two years on R&D, much of it aimed at getting a clean, soda-like body.

ARMRA also chose to avoid the conventional high-heat process that gives most shelf-stable beverages a long life, because it can deactivate some of colostrum’s beneficial properties. Rahal says that is why much of the functional drink aisle is “a flavor story wrapped around an ingredient that stopped being active somewhere in the process.” ARMRA spent years developing a proprietary cold-chain process instead. That is the technical explanation for how the product exists. It doesn’t fully answer the larger question hanging over the category: what one gram of colostrum does for a healthy adult.

The research is still limited. Some clinicians and researchers note that many colostrum studies use daily doses of 10 grams or more, and a single ARMRA can contains one gram. This isn’t another effort to litigate every wellness claim. The more useful question is whether packaging colostrum as a soda changes behavior. Can a supplement ingredient become a daily habit the way a soft drink can?

So far, ARMRA has offered signals, not proof. The brand says teasing the soda on social media lifted engagement by 44 percent, but it didn’t provide a baseline or timeframe. The cans are in specialty grocers like Sprouts and Erewhon, where shoppers are already primed to buy based on function. ARMRA says it has secured 10,000 retail doors nationwide across its entire portfolio, though that is not a soda-specific figure. It did not share sales, reorder or repeat-purchase numbers. Social media engagement, after all, is not the same as habit.

Rahal says she is watching the metric that matters. “Trial only tells you the idea was interesting. Reorders tell you it’s in the routine.” By that logic, a true colostrum-drink category doesn’t exist yet. It will emerge, she says, only when retailers build a shelf set for colostrum drinks, shoppers stop needing the ingredient explained, and repeat purchases carry the business.

That doesn’t mean the soda is a gimmick. It is a live experiment in what the functional beverage aisle can ask people to accept—not just a new flavor, but a new reason to drink soda. ARMRA has proven that colostrum can be made shelf-stable, put in a familiar-looking can and placed alongside Olipop and Recess Mood. It has generated curiosity. The real test isn’t another retail rollout or viral post. It is whether anyone goes back for a second 12-pack.
