The global landscape of alternative proteins is experiencing a profound transformation, driven by surging consumer demand for sustainable, nutrient-dense, and highly functional nutritional products. In a major milestone for the burgeoning food technology sector, Canadian wellness brand Landish has officially introduced an advanced five-plant protein powder. This innovative formulation prominently incorporates Rubisco, a revolutionary protein derived from duckweed, supplied by the United States-based biotechnology pioneer Plantible Foods.
By combining Plantible’s proprietary Rubi Protein with four other carefully selected plant-based ingredients—fava beans, alfalfa, hemp seeds, and spirulina—Landish has created a complete amino-acid profile product designed to meet the rigorous standards of modern health-conscious consumers. Delivering 20 grams of complete protein per 24-gram serving, the launch underscores a broader industrial shift away from traditional, resource-intensive animal proteins and toward scalable, climate-resilient alternatives.
The Chronology of Innovation: From Aquafarms to Mainstream Retail
The commercial debut of Landish’s five-plant protein powder follows a rapid sequence of strategic developments for Plantible Foods, highlighting the accelerating momentum of duckweed-derived ingredients in the North American market.
In February, Plantible achieved a critical regulatory milestone when it secured a "no questions" letter from the United States Food and Drug Administration (FDA). This federal acknowledgment officially permitted the startup to supply its duckweed-derived Rubisco ingredients to food manufacturers for formulations containing up to 5 percent of the component.
Building on this regulatory clearance, Plantible completed a major financial round in August, securing $35 million in combined loan and equity funding. Led by X-Caliber Rural Capital—a specialized licensed lender working in conjunction with the United States Department of Agriculture (USDA)—the capital infusion brought Plantible’s total funding raised to date to $92 million.
The company immediately earmarked these funds to exponentially scale its manufacturing infrastructure. Plantible is currently expanding its flagship 100-acre enclosed aquafarm facility, located in Eldorado, Texas, by constructing up to 50 new greenhouses. This strategic expansion is projected to multiply the facility’s production capacity fivefold, elevating annual output from its initial 100-tonne baseline to over 1,000 tonnes of pure protein. This state-of-the-art production model relies on a controlled crop cycle designed to insulate the supply chain from seasonal agricultural volatility and extreme weather events, while simultaneously generating stable, year-round employment for rural communities.
Understanding Rubisco: The Most Abundant Protein on Earth
To comprehend the significance of this product launch, it is essential to examine the unique scientific and nutritional profile of Rubisco. Formally known as ribulose-1,5-bisphosphate carboxylase-oxygenase, Rubisco is widely recognized as the most plentiful protein on the planet, existing within the green leaves of virtually every plant on Earth. Despite its ubiquity, isolating and utilizing Rubisco efficiently for human consumption has historically presented formidable technical challenges.
Plantible Foods surmounted these hurdles by utilizing duckweed—specifically Lemna, commonly referred to as water lentils. These free-floating freshwater aquatic plants form a vibrant green carpet across aquatic surfaces and have a historical precedent of human consumption in Southeast Asia spanning centuries. In recent decades, however, agricultural scientists and food technologists have reexamined duckweed through the lens of modern sustainability and nutrition.
Duckweed boasts the title of the fastest-growing plant in the world, exhibiting a phenomenal doubling rate of just two to three days. Crucially, its cultivation requires zero arable farmland and causes no deforestation. Plantible cultivates its lemna in highly controlled aquafarms where freshwater is systematically recycled and refreshed, resulting in a water footprint that is approximately ten times lower than that of conventional soybeans.
When harvested, the lemna is milled, filtered, and dried, allowing processors to extract pure Rubisco protein from the leaves. The resulting output demonstrates extraordinary efficiency: Plantible’s Rubisco boasts a nutritional yield of 70 percent, vastly outperforming traditional protein sources such as soy (46 percent), pea (28 percent), and beef (27 percent). Furthermore, the ingredient achieves a Protein Digestibility-Corrected Amino Acid Score (PDCAAS) of 1.0, the highest attainable score, signifying that it provides all nine essential amino acids in optimal proportions for human physiological needs.
Nutritional Synergy: The Five-Plant Formulation
Landish engineered its new protein powder not merely to leverage the novelty of duckweed, but to establish a holistic wellness product through the synergistic combination of five distinct plant sources. Alongside Plantible’s Rubi Protein, the blend incorporates fava beans, alfalfa, hemp seeds, and spirulina.
Each component contributes specialized functional and nutritional attributes to the final blend:
- Fava Beans: Renowned for their rich content of L-Dopa, a natural compound that supports healthy dopamine production, fava beans also supply valuable bioactive peptides possessing pronounced antioxidant and anti-inflammatory properties.
- Alfalfa: A nutrient-dense botanical source that delivers essential amino acids, critical trace minerals, and bioactive compounds instrumental in supporting cellular repair and maintaining long-term cardiovascular health.
- Hemp Seeds: Packed with balanced omega fatty acids, dietary fiber, and antioxidants, hemp seeds contribute effectively to sustained muscle maintenance, increased satiety, and comprehensive micronutrient intake.
- Spirulina: This nutrient-dense blue-green microalga is exceptionally rich in protein, B-complex vitamins, phycocyanin, and prebiotic polysaccharides. It aids in natural energy production, promotes optimal gut and immune health, and assists in mitigating oxidative stress.
To ensure maximum digestive comfort and nutrient bioavailability, Landish formulated the blend without added sugars, artificial sweeteners, or synthetic flavorings. Instead, the mixture is integrated with a specialized protease enzyme derived from the controlled fermentation of Aspergillus oryzae. This enzyme actively breaks down complex proteins into smaller peptides and amino acids, thereby enhancing intestinal absorption, improving overall digestibility, and virtually eliminating common post-consumption issues such as bloating.
Market Implications: Addressing Structural Vulnerabilities in Global Food Supply Chains
The strategic collaboration between Landish and Plantible Foods arrives at a critical juncture for the broader food and beverage industry. Global agricultural markets have faced severe disruptions, marked by ongoing price volatility and supply shortages affecting traditional protein commodities such as whey and eggs. These economic pressures have accelerated the search for scalable, functional, and cost-effective alternatives capable of meeting industrial manufacturing requirements.
Plantible’s Rubisco protein offers functional characteristics that directly rival animal-derived ingredients. Beyond its flagship Rubi Protein powder, the company produces specialized derivatives such as Rubi Whisk, which provides structural integrity, moisture retention, and oil-binding properties tailored for egg-free and gluten-free baked goods like macarons, cookies, and delicate tarts. Additionally, its Lemna Leaf Greens product offers a mild-tasting, nutrient-rich powder optimized for ready-to-mix beverages, functional nutrition bars, and specialized dietary supplements.
The commercial application of Rubisco is rapidly gaining traction across the marketplace. Beyond Landish’s integration of the protein into its new five-plant powder and existing matcha latte mixes, other major industry players are adopting similar technologies. For instance, ingredient giant ICL Food Specialties has incorporated Plantible’s technology into its Rovitiras Binding Solution, designed specifically for advanced meat and seafood alternatives.
Concurrently, the wider competitive landscape is witnessing parallel innovations. In the United States, competitors such as Fudi Protein have secured early-stage venture funding to commercialize alfalfa-derived Rubisco proteins as direct substitutes for dairy and egg whites. Meanwhile, retail chains like the San Francisco Bay Area-based Palmetto Superfoods have introduced consumer-facing offerings such as the "Blade Smoothie," which features alfalfa-based Rubisco sourced from New Zealand food-tech innovator Leaft Foods.
Industry analysts suggest that these developments signal a permanent structural evolution in the nutritional supplement and packaged foods sectors. As biotechnology startups successfully scale production capacity and secure broad regulatory approvals, plant-based proteins are systematically transitioning from niche dietary alternatives into foundational pillars of mainstream global nutrition. For brands like Landish and ingredient innovators like Plantible Foods, the successful commercialization of duckweed-derived Rubisco represents a vital step toward a more secure, sustainable, and nutritionally robust food future.
