PepsiCo has announced a new protein portfolio strategy, unveiling three scientifically informed beverage innovations set to launch in early 2026. The move marks a shift away from the industry’s fixation on “grams of protein” and toward what the company describes as “outcome-based nutrition” – offering the right formulation for the right consumer, at the right time.

Tara Glasgow, PepsiCo’s Global Chief Science Officer, said the company’s approach is rooted in both consumer insight and nutritional science. “Most people don’t realise that it’s not just how much protein you consume – it’s when and what type of protein that matters,” she explained. “Your body can only use so much at once, so spreading protein throughout the day helps maximise its benefits. That’s why our innovations are designed to deliver protein and other functional ingredients in the right form, at the right time, for the right person.”

Propel, Muscle Milk and Starbucks Coffee + Protein each target distinct consumer needs

The new product range spans three major brands: Propel, Muscle Milk and Starbucks (through the North American Coffee Partnership). Each line is tailored to distinct needs—from hydration and muscle maintenance to morning wellness.

Propel Clear Protein introduces a new dimension to functional hydration. The powder mix features a proprietary blend of whey protein, fibre and electrolytes to support muscle health, digestion and hydration. Each serving provides 20g of protein, 3g of fibre and added electrolytes, with no artificial flavours, sweeteners or colours. Designed for active consumers, it’s also positioned as a supportive option for GLP-1 users who benefit from supplemental protein and fibre. Flavours include Pear Apple, Watermelon Mint and Peach Ginger.

Muscle Milk—a long-standing brand for athletes and active individuals—has undergone a complete reformulation. The new recipe integrates ultra-filtered milk for improved texture and taste, while removing artificial ingredients and added colour. The range will feature two variants: Muscle Milk Base (26g protein) and Muscle Milk Pro (42g protein), each with 3g sugar, 200 calories per serving, and added calcium and vitamins A and D. The update will also include modernised packaging to reflect the cleaner formulation.

Meanwhile, the Starbucks Coffee + Protein line aims to extend the morning coffee ritual into the wellness space. The beverage combines 100 percent Arabica coffee with 22g of protein, 5g of prebiotic fibre and five essential vitamins and minerals – all with only 2g of sugar. Available in Classic Caffé and Caffé Mocha flavours, the drink targets consumers seeking both performance and balance.

Ram Krishnan, CEO of PepsiCo Beverages North America, said the new strategy redefines how protein fits into daily life. “We’re focused on delivering protein in ways that work with the body, not just adding grams,” he explained. “Whether it’s muscle maintenance with Muscle Milk, hydration and digestive support with Propel Clear Protein, or morning wellness with Starbucks Coffee + Protein, each brand is designed with precision to meet unique physiological and emotional needs.”

With its 2026 protein portfolio, PepsiCo is betting that consumers will increasingly prioritise functionality, flavour and science-backed nutrition over simple macronutrient counts – signalling a new phase in the evolution of functional beverages. This news follows Starbucks introduction of a new range of protein coffees in stores for September.
