Mía launches fiber-first protein shake for GLP-1 consumers

Mía is making a clear bet that fiber, not protein alone, is the next big sell in functional nutrition. Its new Fiber-First Shake delivers 22 grams of fiber and 27 grams of protein per serving, a combination aimed squarely at consumers using GLP-1 medications and at shoppers chasing the fibermaxxing trend.

The company is also leaning hard into the gap it says most competitors miss. Mía says many protein shakes marketed as high fiber contain only 3 to 10 grams of fiber, which leaves a wide opening for a product built around digestive support and fullness as much as muscle maintenance. The shake also includes adaptogens, digestive enzymes, supergreens, and more than 15 vitamins and minerals, all packaged in a 15-serving format that signals everyday use rather than a one-off recovery drink.

The timing fits where the conversation around GLP-1 nutrition has gone. On May 30, 2025, the American College of Lifestyle Medicine, the American Society for Nutrition, the Obesity Medicine Association, and The Obesity Society issued a clinical advisory on nutritional priorities for GLP-1 therapy. The guidance emphasized baseline nutritional assessment, managing gastrointestinal side effects, preventing micronutrient deficiencies, and keeping protein intake high alongside strength training to preserve lean mass. Mía’s pitch tracks that logic, but shifts the emphasis toward fiber as the missing macro for people who are eating less and trying to make each calorie work harder.

That focus also matches the broader fiber problem in the United States. The U.S. Dietary Guidelines recommend roughly 22 to 34 grams of fiber a day for adults, depending on age and sex, yet nutrition groups and studies say only about 5% to 10% of Americans meet those targets. UCLA Health added fuel to the trend on January 6, 2026, when it explained how fibermaxxing had gone viral, even as experts cautioned that high-fiber eating should still be approached sensibly.

Mía is entering a field that is already crowding around GLP-1-friendly nutrition. todo has pushed ready-to-drink shakes with 26 grams of protein and 6 grams of prebiotic fiber. BOOST Advanced Nutritional Shake offers 35 grams of protein and 4 grams of prebiotic fiber. Oikos has also moved into the category with a GLP-1-weight-loss-journey shake focused on muscle support during weight loss. Mía’s launch shows where the aisle is heading: less about protein grams alone, more about a bundled answer to appetite suppression, satiety, digestion, and the practical reality of eating smaller meals.
