Downers Grove – September 24, 2026 -- Optimum Nutrition has launched a new ready-to-drink shake combining 30 grams of protein with 8 grams of prebiotic fiber, targeting consumers who want both muscle support and gut health benefits in one product.

Fiber joins protein as a top consumer priority

Roughly 31% of Americans say they're seeking more fiber in their diets than a year ago, according to Ipsos data cited by the brand. Nearly one-third of Americans fall short of the recommended 28 grams of daily fiber, per the International Food Information Council. Optimum Nutrition's new 30G Ultra-Filtered Milk Protein Shake + Fiber aims to close that gap without sacrificing taste.

Ultra-filtered milk delivers a denser protein shake

The shake uses ultra-filtered milk to boost protein density while keeping a smooth, creamy texture. It's gluten-free and made without artificial flavors, colors or sweeteners, and comes in Chocolate, Vanilla and Strawberry flavors.

The launch marks Optimum Nutrition's 40th year in sports nutrition

Dave Lombardi, Senior Brand Manager at Optimum Nutrition, said the shake reflects the brand's effort to evolve alongside shifting consumer priorities while keeping protein at its core. WNBA player Cameron Brink, a brand partner, said she now pays close attention to fiber and gut health alongside protein in her own routine, calling the shake an easy grab-and-go option between practices, games and travel.

Where and how much it costs

A 4-pack sells for $12.99 on Amazon, while a 12-pack costs $39.99 on TikTok Shop and OptimumNutrition.com. The shake is rolling out to additional retailers across the country through the fall.
