Your morning coffee just got swole. Starting September 29, Starbucks will roll out protein-boosted lattes and cold foams across all U.S. and Canadian locations, delivering between 15 to 36 grams of protein per grande serving. This isn’t some half-hearted wellness play—it’s a direct response to market research showing 70% of Americans want more protein in their diets, according to the IFIC Food & Health Survey, and the protein shake industry now pulling in over $6 billion annually.
The menu expansion breaks into two camps: protein lattes packing 27 to 36 grams through specially formulated protein-boosted milk, and protein cold foams adding about 15 grams to any cold coffee, tea, or Refresher. The cold foams come in eight flavors including:
- Banana
- Vanilla
- Chocolate
- Matcha
- Seasonal options like pumpkin and pecan
You can also customize any cold drink with protein-boosted 2% milk for an extra 12 to 16 grams. The protein boost comes from added protein powder formulated specifically for Starbucks beverages, though the company hasn’t specified whether it’s whey-based or plant-derived protein.
“We’re modernizing the menu with hype-worthy products that will resonate with customers,” says Tressie Lieberman, Starbucks’ global chief brand officer. The timing makes sense—high-protein drink launches have jumped 122% since 2020, riding the wave of functional wellness trends that TikTok influencers have pushed into mainstream culture. This isn’t just about fitness fanatics anymore; it’s busy professionals seeking convenient nutrition and anyone tracking their daily macros.
Starbucks developed these offerings through their Starting 5 innovation program, where new drinks get tested at select locations for feedback before nationwide rollout. The protein cold foams mark the first Starting 5 product to earn permanent menu status. Both product lines include sugar-free and unsweetened options, acknowledging that not everyone wants their protein delivery sweetened to dessert levels.
The question isn’t whether people want more protein—they clearly do. It’s whether powder-enhanced coffee represents smart nutrition or just convenient marketing. Registered dietitians consistently emphasize balancing supplemental protein with whole food sources like lean meats, legumes, and eggs. Your latte can boost your daily numbers, but it shouldn’t replace actual meals.
