Protein is no longer just for bodybuilders. Today, ready-to-drink (RTD) protein beverages are one of the fastest-growing segments in the functional beverage market, appealing to athletes, busy professionals, and everyday consumers looking for convenient nutrition. The protein beverage market has exploded in recent years, and innovation shows no signs of slowing down.
At Bernick’s, we’ve seen firsthand how protein beverage trends have shifted from niche products to mainstream must-haves. Whether it’s plant-based options, clear protein formats, or added functional benefits, protein drinks are redefining what people expect from their beverages.
The Protein Beverage Boom: Market Size & Growth
The growth trajectory of protein drinks is remarkable.
- The global protein beverages market is projected to grow from approximately $16.8 billion in 2025 to $25 billion by 2035.
- North America leads the charge, with RTD sports and protein drinks valued at around $2.24 billion in 2025, expected to reach $3.08 billion by 2030.
- More broadly, the U.S. functional beverage category — which includes protein drinks — is on track to hit $320 billion by 2028.
This isn’t just a passing trend. It’s a shift in how people view nutrition, wellness, and convenience.
Why Ready-to-Drink Protein Drinks Appeal to Both Wellness & Workplace
The convenience of protein beverages has expanded their audience well beyond gyms and sports fields.
- Consumer focus on health: In 2025, 85% of Americans reported actively increasing protein intake.
- Mainstream adoption: Even major coffee chains are joining in. Starbucks recently launched a cold foam topping with 15g of added protein, proving protein has gone mainstream.
- Workplace wellness: RTD protein drinks fit perfectly into micro markets, vending machines, and workplace wellness programs, giving employees an easy way to fuel their day.
- Aspirational lifestyle: Premium wellness brands have positioned protein drinks not just as fuel, but as part of a healthy, on-the-go lifestyle that consumers feel good about.
For operators, stocking protein drinks is more than offering a snack — it’s meeting employees, visitors, and customers where their wellness goals already are.
Plant-Based, Clear, & Clean: Protein Formats That Sell
Not all protein drinks look (or taste) the same anymore. Today’s consumers want options that align with dietary preferences and lifestyles.
- Plant-based protein – Pea, soy, rice, and hemp proteins are fueling demand among flexitarians and vegans. Many brands now blend different plant proteins for better amino acid balance and smoother taste.
- Clear protein – A lighter, juice-like format that is lactose-free, refreshing, and easy to digest. Perfect for people who dislike the heaviness of traditional shakes.
- Clean labels – Consumers are reading labels more closely. Products without artificial sweeteners, dyes, or fillers — and those that highlight natural flavors and simple ingredients — win trust.
These formats not only broaden the consumer base but also increase trial and repeat purchases.
Flavor + Function: Innovation in Protein
The days of chalky vanilla or basic chocolate are long gone. Today’s protein beverage trends combine bold flavors with added functional benefits to meet consumer demand.
Popular Functional Add-Ins
- Fiber – For satiety and digestive health
- Probiotics – Supporting gut health and immunity
- Adaptogens – Natural stress-relievers like ashwagandha and reishi
- Collagen – For skin, hair, and joint health
- Electrolytes – Supporting hydration and recovery
Trending Flavors
- Salted caramel – Dessert-inspired indulgence without the guilt; coffee-based protein drinks are evolving, too
- Matcha-coconut – A blend of energy and wellness
- Tropical fruits – Pineapple, passionfruit, and mango for refreshment
- Dessert blends – Cookie dough, s’mores, and birthday cake for fun flavor experiences
This “flavor + function” trend is pushing protein beverages beyond utility and into everyday enjoyment, making them a staple in more consumers’ lives.
