Optimum Nutrition Debuts Protein Shake With 8g of Prebiotic Fiber
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.
