Plant-based proteins gain ground as formulation advances improve performance

Plant protein is no longer asking shoppers to forgive its flaws. The category is advancing on the exact points that used to hold it back: digestibility, texture, solubility and flavor, with market forecasts pointing to global growth from $23.89 billion in 2025 to $34.97 billion by 2030. That shift matters because the winning products are starting to feel less like compromises and more like polished nutrition systems that fit real routines.

The comeback is being built on performance, not just sourcing

Pea protein has become one of the clearest beneficiaries of that reset because it brings a strong amino acid profile and relatively low allergenicity, two attributes that make it easier to position for mainstream use. At the same time, the pipeline is widening fast, with microalgae, seaweed, crop byproducts and mushroom mycelium adding new options for brands that want a more differentiated story than just another pea or soy blend.

That broader ingredient mix is important because the market is no longer only about finding a plant source. It is about whether the finished protein behaves the way formulators need it to behave in a shake, a water, a snack bar or a ready-to-mix beverage. In practice, that means the category is judged on what consumers actually feel: whether it mixes cleanly, drinks smoothly and delivers a nutrition profile that looks credible beside whey.

Digestibility is the benchmark plant protein has to clear

The biggest technical hurdle remains digestibility, and that is where the story becomes more interesting than the usual plant-versus-dairy debate. Whey isolate approaches 100% digestibility, while many plant proteins still land lower, although pea concentrate and soy isolate compare favorably within the plant category. That distinction matters because it shows the opportunity is not simply to change the source, but to improve how the protein is processed and delivered.

A 2017 British Journal of Nutrition study comparing whey protein isolate, whey protein concentrate and milk protein concentrate with pea protein concentrate, soy protein isolate, soy flour and whole-grain wheat found higher indispensable amino acid digestibility in the dairy proteins. It also warned that PDCAAS-like values in pigs may overestimate the quality of some plant proteins. In other words, not every protein that looks good on paper behaves the same once the body has to work through it.

That is where the quality conversation gets more nuanced. The FDA still uses PDCAAS for protein content claims and the nutrition facts panel, while the broader nutrition literature has long argued that DIAAS can better reflect protein quality in some cases. A 2022 Frontiers in Nutrition review helps explain why soy remains a benchmark plant protein, finding mean PDCAAS of 92.4 after excluding post-processed data and mean DIAAS of 86.0, while also showing that processing and post-processing conditions can raise or lower protein quality.

Processing is now part of the product strategy

That last point is the real hinge for manufacturers. Plant protein innovation is not just about selecting soy, pea or a newer source; it is about how the protein is handled after extraction, because the processing step can make the difference between a gritty, flat-tasting product and one that actually earns repeat purchase. The companies that are winning are treating processing as part of the formulation, not an afterthought.

That is also why new sources are only half the story. If the ingredient cannot deliver a stable drink, a clean label and a usable texture, it stays stuck in ingredient-nerd territory. Successful products are increasingly the ones that combine better texture, better flavor and clearer nutrition positioning, which is a much higher bar than simply being plant-based.

The beverage format is where the category is most visibly maturing

Clear beverages are one of the strongest signs that plant protein has learned how to show up in a more consumer-friendly form. Axiom Foods said demand for its clear pea protein and clear rice protein had doubled production year over year in October 2024, after launching the clear proteins in 2022 for high-acid and low-pH beverages such as coffee, citrus drinks, beer and electrolytes. That matters because acidic drinks are one of the toughest environments for protein, and surviving there opens up a huge range of lighter, more refreshing formats.

Axiom’s founder said clear pea protein had become one of only a couple clear protein options on the market, which tells you how tight the supply is even as demand expands. Still, the direction is clear: plant proteins are moving from opaque shakes into clear protein waters and acidified drinks that can carry up to about 30 grams of protein per serving. That is a meaningful shift because it gives consumers a protein hit without the heavy, milky profile many people still associate with traditional shakes.

The broader beverage market is validating that appetite for functional, easy-to-drink protein. PepsiCo announced Propel Clear Protein on May 6, 2026 as a ready-to-mix powder with 20 grams of whey protein, 3 grams of fiber and electrolytes, sold through Walmart.com, Amazon, Gatorade.com and TikTok Shop. PepsiCo said it was developed with registered dietitians and targeted at consumers including GLP-1 users, which underscores how far protein positioning has moved from bodybuilding toward everyday functional hydration.

Consumer demand is still strong, but knowledge gaps remain wide

The demand side is doing plenty of work here. IFIC’s 2025 Food & Health Survey found that 71% of Americans were trying to consume protein in 2025, up from 67% in 2023 and 59% in 2022. It also found that 35% of respondents increased protein consumption in the last year, which helps explain why protein has remained the most sought-after nutrient among Americans for five consecutive years.

But the same survey also shows why brands still have room to educate. Fifty-three percent of respondents said they were unaware of how much protein they need daily, and another 26% said they were unsure. Among the benefits people associate with protein, 51% pointed to muscle health and strength, 45% to energy and less fatigue, and 35% to overall well-being. That creates a huge opening for products that make the benefit obvious, since consumers may want more protein without fully understanding how to choose the right format or source.

IFIC’s research also shows the scale of the opportunity behind the data. The 2025 Food & Health Survey was its 20th consecutive annual survey, fielded March 13-27, 2025, and its Spotlight Survey on protein perceptions was fielded May 10-13, 2025 with 1,000 U.S. adults. The big message from both is the same: consumer enthusiasm is strong, but consumer understanding is still shaky, which leaves a lot of room for sharper product positioning.

What the next phase looks like

The practical takeaway for manufacturers is that plant protein is increasingly being judged as a platform, not a fallback. It has to solve allergen concerns, support sustainability goals, and still deliver a drink or snack that feels good enough to buy twice. The brands that get this right will not just sell protein from plants; they will sell a cleaner, lighter, easier protein experience that happens to be plant-based.

That is why the category feels more credible now than it did a few years ago. Better digestibility data, stronger formulation tools and more flexible beverage formats are finally addressing the complaints that kept plant protein in a niche lane. If those gains keep compounding, the next wave of growth will come not from the core vegan crowd, but from mainstream shoppers who simply want protein that works.
