Mía launches high-fiber protein shake with digestive enzymes and adaptogens

In the advent of “fibermaxxing” and GLP-1 weight loss, Mía has launched its Fiber-First Shake, a high-fiber protein shake formulated to address a major nutritional gap.

According to the brand, many protein shakes marketed as “high fiber” contain around 3–10 g. Its own product delivers 22 g of fiber and 27 g of protein per serving, plus adaptogens, digestive enzymes, “supergreens,” and more than 15 vitamins and minerals in 15 servings per pack.

“I created Mía after finding no shake that prioritized fiber without giving up the protein. I didn’t want to compromise one thing to get another. For anyone on-the-go who can’t take twenty different things, this shake delivers consistency and results,” says Jennifer Holt, founder of Mía.

Critical nutrition gap

Citing data from the journals Molecular Nutrition & Food Research and American Journal of Lifestyle Medicine, Mía outlines that 95% of US consumers are not ingesting enough fiber. 

In the US, daily intake averages just 14–16 g. However, Mía stresses that women need 25–30 g and men need 38 g.

For consumers on GLP-1 medications eating less overall, the fiber gap becomes even harder to close. Without sufficient fiber, high-protein diets shift gut microbiota toward protein fermentation, producing harmful byproducts.

“Fiber isn’t just an add-on. It’s what makes protein work better,” states Mía.

Mía Fiber-First Shake contains acacia gum fiber, organic pea and rice protein, and a FOS (fructooligosaccharides) prebiotic blend.The Fiber-First Shake contains dietary fiber from acacia gum and organic pea and rice protein, along with a FOS (fructooligosaccharides) prebiotic blend.

The product offers 17 digestive enzymes for gut comfort and absorption, as well as functional mushrooms including lion’s mane, cordyceps, and chaga.

For “supergreens,” the formula features spirulina, chlorella, barley grass, and wheat grass. Antioxidant fruits include camu camu, maqui berry, and pomegranate.

Each sugar-free serving has 200 calories per serving and comes in a chocolate flavor sweetened with monk fruit.

Fiber-forward formulations

According to Innova Market Insights data, the market for fiber-rich products is saturated, especially in the functional beverages category, prompting manufacturers to refine their messaging, claims, and packaging strategies to engage overwhelmed consumers.

The global market researcher stresses that brands that highlight the overall health advantages, not just gut health, of prebiotics and fiber, in addition to educating consumers, are more likely to succeed in the market. As such, innovative fiber formulations are becoming more refined to encompass broader health target areas.

Earlier this year, Momentous launched Fiber+, a “triple-action” fiber supplement designed to go beyond digestion and to support gut health, metabolic balance, and a whole-body recovery. The company leveraged the latest science on fermentable fibers, resistant starch, and the production of short-chain fatty acids. The supplement contains psyllium husk, rice bran, potato starch, and cinnamon bark.

Meanwhile, recent research that was partly funded by ingredient supplier Tate & Lyle revealed that daily soluble corn fiber significantly improves cognition and focus in healthy middle-aged and older adults, while also boosting gut bacteria that may support brain function.
