Optimum Nutrition has launched its 30G Ultra-Filtered Milk Protein Shake + Fiber, a ready-to-drink format that stacks 30g of ultra-filtered milk protein with 8g of prebiotic fiber per serving — a formulation move that directly addresses two of the fastest-growing consumer priorities in functional nutrition. The product is now available as a 4-pack ($12.99) on Amazon and as a 12-pack ($39.99) on TikTok Shop and OptimumNutrition.com, with a broader retail rollout planned through fall.
The Formulation Case
Ultra-filtration concentrates milk protein by removing water, lactose, and minerals, yielding a more protein-dense base than conventional whole or skim milk — a process documented in peer-reviewed dairy science literature. The resulting finished formulation is gluten-free and contains no artificial flavors, colors, or sweeteners, positioning it squarely in the clean-label segment of the protein and functional beverage category. The 8g prebiotic fiber dose is meaningful given that structure-function claims for gut microbiome support typically require a minimum effective dose; at 8g per serving, the product provides roughly 29% of the 28g daily recommended fiber intake, addressing what a 2026 International Food Information Council report identifies as a widespread shortfall — nearly one-third of Americans consume less than the recommended daily value.
Market Timing
The dual protein-plus-fiber positioning reflects a real shift in consumer intent. A May 2026 Ipsos survey found that 31% of Americans are actively seeking products with more fiber compared to a year prior — a statistic that tracks alongside sustained growth in the sports nutrition RTD segment, where brands are under pressure to differentiate beyond protein grams alone. Optimum Nutrition, a Glanbia Performance Nutrition brand ranked as the world's number-one sports nutrition brand by retail value share per Euromonitor International's 2025 Consumer Health edition, is using the launch to signal category evolution rather than simple line extension. Dave Lombardi, Senior Brand Manager at Optimum Nutrition, framed it as a deliberate response to consumers who increasingly expect multi-benefit functionality from a single SKU: "Protein will always be core to who we are as a brand, but we are committed to growing and evolving with our consumers as their needs and routines change."
Retail and Athlete Strategy
The launch is available in Chocolate, Vanilla, and Strawberry variants — each formulated around ultra-filtered milk for a creamy, milk-forward sensory profile rather than the chalky texture often associated with high-protein RTDs. Distribution through TikTok Shop alongside Amazon reflects a broader industry trend of sports nutrition brands meeting younger, fitness-focused consumers on social commerce platforms where product discovery and purchase happen in the same session. WNBA athlete Cameron Brink serves as a brand partner, lending the launch an on-court performance narrative that reinforces the dual muscle-and-gut positioning for active consumers. The product's 40th-anniversary timing for the Optimum Nutrition brand adds category credibility to what is, structurally, a gut health and prebiotic play embedded inside a sports nutrition format — a crossover increasingly common as the gut-health market matures and bleeds into mainstream functional beverage SKUs.
