It's easy to notice that the drinks in workers' hands have recently become higher in protein. In April 2026, Starbucks China officially launched its high-protein latte Pro series, with a grande size containing 20 grams of protein. It went viral on social media upon release, and 'protein latte' has become a trendy item among fitness enthusiasts. Dairy companies focused on supermarket shelves naturally won't miss this new direction. In May, Mengniu launched M-PLUS Daily Protein Milk, with 15 grams of native milk protein per 250ml bottle, marketed under the slogan 'open and drink, precise replenishment'. Mengniu M-PLUS Daily Protein Milk Long-time rival Yili is not to be outdone, launching Puritime transparent protein water around the same time; Bright Dairy is quietly positioning itself through technical patents. In a short period, dairy giants, coffee chains, and even retail channels have collectively bet on this, causing the high-protein beverage track to heat up suddenly. This is not the first time the beverage industry has 'added new ingredients' to bottles. Over the past few years, beverages have become more like 'fitness supplements': first, there was the '0 sugar 0 calorie' trend, using various sugar substitutes to replace white sugar, targeting 'calorie panic'; then vitamins, from vitamin C lemon tea to B-vitamin functional drinks; then potassium-containing electrolytes, from Pocari Sweat, Alien, to giants like Nongfu Spring and C'estbon, all revitalizing the sports drink concept. Now it's protein's turn. According to Innova Market Insights, the proportion of new beverage products globally claiming 'high protein' in 2025 has risen from 0.5% five years ago to 4.4%. Stratistics MRC predicts that the global protein beverage market will reach $5.3 billion by 2026. A pressing question is: Why are beverages becoming more like supplements? And is this really a good thing? Who is paying for 'protein-containing beverages'? The rise of high-protein beverages first addresses the real pain points of hardcore fitness enthusiasts. Anyone with regular training experience knows the scene: after the last set, muscles are sore, heart rate hasn't fully dropped, and the most important thing is to replenish protein as soon as possible. But the subsequent series of actions—finding water, measuring powder, shaking, and washing the shaker cup—each step drains already depleted willpower. Ready-to-drink protein beverages simplify this entire sequence into 'twisting off the cap'. For the 'golden recovery window' of 30-60 minutes post-exercise, repeatedly emphasized by exercise physiology, this convenience is not just laziness; it genuinely makes 'timely post-workout replenishment' easier to stick with. Image source: Visual China But relying solely on fitness enthusiasts cannot support the giants' ambitions for this track. What truly pushes high-protein beverages to the mass market is the health anxiety of more ordinary people. According to industry analysis, the core audience for Starbucks' high-protein latte PRO is not hardcore fitness enthusiasts, but urban white-collar workers aged 25-35. They may not have regular training habits, but they generally live in a rhythm of 'skipping breakfast, minimalist meals', with a long-term protein intake gap. This group has some awareness of nutritional supplements—they've heard of whey protein and know its importance for maintaining muscle and immunity, but if asked to buy tubs of protein powder and time their shakes like fitness buffs, they simply don't have the time. High-protein beverages hit this psychological gap perfectly. They don't change any consumer habits; they just add an extra serving of protein to daily coffee. Starbucks' communication strategy confirms this: the conversion 'one cup = 3 eggs = a small steak' anchors abstract protein grams to everyday foods, so consumers don't need to understand nutrition to grasp it at a glance. Starbucks High-Protein Latte Pro Series Similarly, Mengniu has set two parallel usage scenarios for M-PLUS: timely replenishment after exercise and nutritional management in daily life. The implication is clear: high protein is not just needed after workouts; it can become part of ordinary people's daily diet. The essence of this approach is that brands try to 'parasitize' their products into consumers' established habits. You don't need to deliberately remember to supplement protein; you can do it while drinking a cup of coffee or a bottle of water. For urban white-collar workers with fast-paced lives and no time to scrutinize nutritional combinations, this 'incidental' approach hits their hidden concerns about their health. A nutrition researcher once observed in an interview: 'People are increasingly willing to pay for "effortless health", even if that "health" is more of a psychological comfort.' Mengniu M-PLUS Daily Protein Milk But between 'incidental' and 'truly needed', there is sometimes a subtle line. Protein, as one of the three macronutrients, has clear daily intake recommendations and broad consumer awareness, which makes it easier to convince ordinary people to buy compared to other functional ingredients. However, when a category starts using the logic of 'grab a bottle and get healthier' in market communication, the boundary between anxiety marketing and genuine need becomes harder to distinguish. How can 'functional beverages become daily' work? If the rise of high-protein beverages is driven by demand, whether they can truly move from niche to daily depends on the other end—whether the supply side can solve three things. First, experience. Any beverage's ultimate question is whether it tastes good. High-protein beverages carry an inherent burden in taste. Regular raw milk has a protein content of about 3.0-3.3g/100ml. To achieve above 6.0g/100ml without relying on externally added protein powder, multi-stage membrane separation technology is needed—ultrafiltration membranes retain protein and fat, nanofiltration membranes handle lactose, and then components are precisely reassembled at low temperatures. A study published this year in the domestic journal 'Food Industry Science and Technology' shows that if any parameter such as operating pressure, temperature, or membrane molecular weight cutoff is improper, the separation effect is greatly compromised; research in the international dairy science journal 'Journal of Dairy Science' confirms the difficulty from another angle: lowering the ultrafiltration temperature from 50°C to 7°C doubles the processing time. The technical complexity ultimately shows up on the palate. The viscous texture from high protein concentration is a physical reality, and to mask the bitterness from enzymatic hydrolysis in lactose-free formulas, sweetness often needs to be increased. After Starbucks' high-protein latte launched, social media saw polarizing reviews: 'very creamy, like melted milk ice cream' versus 'no coffee flavor, too sweet and cloying'. A 2026 survey by iiMedia Research corroborates this industry-wide pain point: one-third of consumers believe 'health and taste are hard to balance'. In other words, consumers want health but are unwilling to compromise on flavor—high-protein beverages have yet to find the optimal solution to this contradiction. Second, standards. Currently, the domestic high-protein beverage market lacks unified classification and access standards. Among products called 'protein water', some follow sports nutrition food standards, some are filed under national standards for flavored beverages, and others use corporate proprietary standards. There is no consensus on category definition, efficacy claim boundaries, or quality control. This creates two levels of problems. For consumers, inconsistent standards mean they can't easily compare products: a product made to sports nutrition standards and one made to flavored beverage standards, even if both are called 'high-protein beverages', may differ significantly in nutritional content and quality control. For the industry, the lack of unified standards means many companies can enter with very low barriers and lower costs, using vague marketing to grab market share, leading to a race to the bottom. For the long-term standardized development of the entire track, this is an unavoidable hurdle. Third, cost. Technical barriers ultimately reflect in price tags. Mengniu M-PLUS is priced around 10-15 yuan per 250ml, while Yili's Puritime protein water is 9.9 yuan per 300ml. Breaking down the protein content, each bottle contains 10-15 grams of protein, translating to a cost per gram of protein of about 0.7 to 1.5 yuan. Yili Puritime Protein Water In contrast, traditional tubs of whey protein powder cost about 0.4-0.6 yuan per gram of protein. In comparison, ready-to-drink high-protein beverages have a clear 'convenience premium'. This premium includes the immediacy of no mixing, the process investment in cold chain or aseptic filling, and the 'open and drink' consumption scenario. But the premium also sets a realistic boundary: a price of 9.9-15 yuan per bottle makes it hard to become a daily 'staple drink'. Stratistics MRC's global market report also notes that the high cost of protein beverages hinders penetration in developing markets, and they are still seen as 'premium health products' for those with higher disposable income. If supply chain maturity and economies of scale don't continuously drive costs down, high-protein beverages will find it difficult to enter the 'daily consumption' logic. These three challenges are essentially a set of interdependent variables: better taste means more complex technology and higher costs; lower costs mean trade-offs in ingredients or processes, which in turn affect taste and nutritional density. Brands are all looking for the optimal solution, but so far, no one has found the right answer. The Many Possibilities of the Trend: Bubble or New Species? Standing at 2026, it's probably too early to judge whether high-protein beverages are a real trend or a passing fad. But the path they've taken shares similarities with sugar-free tea and electrolyte water. When sugar-free tea started, it was also seen as a niche category—bitter, astringent, unsweetened, and no one thought it could compete with iced tea. But after years of category education, technological improvement, and evolving consumer attitudes, sugar-free tea is now a stable multi-billion-yuan track. Electrolyte water is a similar story—the Alien brand started from sports scenarios, gradually penetrated daily hydration, and eventually grew into an independent category. The common feature of these two paths is: initially gaining traction through specific scenarios and groups, then breaking out through product experience optimization, and finally becoming a daily choice through habit formation. High-protein beverages are currently in the first stage. Their most solid foothold remains sports recovery scenarios and niche groups like lactose-intolerant individuals. Mengniu Isolated Whey Protein Drink Whether they can move from the first to the second stage still depends on whether those clichéd issues can be solved: can taste be improved, can standards give consumers stable expectations, and can prices shift from 'try it' to 'drink it daily'. Global market data at least shows that there is real demand underpinning this category, not a fabricated concept. But whether it can replicate the path of sugar-free tea in the Chinese market depends on localization efforts. Worth considering further is that the evolution of this track may not be limited to protein alone. Starbucks has launched high-protein lattes with probiotic fiber in North America, and Mengniu has started adding BCAA and collagen peptides to protein water. The 'beverage supplementization' formula will only get longer. However, protein has a natural advantage—as one of the three macronutrients, its cognitive foundation and daily necessity far exceed other supplement ingredients, making it the most likely to 'break out' first. Maisheng Liquid Protein Drink Of course, we must also calmly see the other side. In the Chinese market, an ordinary office worker earning 8,000 yuan a month spending over ten yuan a day on a 'protein-containing beverage' as a daily expense is a significant conversion challenge. In the end, it probably won't become as ubiquitous as carbonated drinks, but it won't disappear like some internet-famous concepts after a brief hype. A more likely outcome is that it settles into a stable mid-sized market, precisely serving those willing to pay a bit more for convenience and experience. In the final analysis, 'beverage supplementization' is probably not a bubble, but more like a cautious category exploration. The beverage industry hasn't seen a truly new species in a long time. Whether high-protein beverages can become that exception will be seen in the next two to three years. Until then, it has at least made convenience store shelves a bit more interesting—which in itself is a rare thing.
