Contains B vitamins, minerals, and fiber
Complete protein with all 9 essential amino acids and PDCAAS of 1.0
Gluten Free, Allergen Free, Sustainable Protein
The YESTEIN® Advantage
Supports Muscle Recovery
Yeast Protein is high in Branched Chain Amino Acids, which when broken down are converted into glucose, preventing muscle loss and promoting muscle recovery after exercise. 1
Experimental results showed that Yeast Protein contains ≥ 20.0% BCAA, higher than PPI and comparable to WPC.
YESTEIN® is an excellent protein for sports nutrition and an aging population, to support muscular recovery and reduce muscular fatigue/loss.

What is YESTEIN®?
YESTEIN® is a complete, fermentation-derived yeast protein (Saccharomyces cerevisiae) with a PDCAAS of 1.0 and a full essential amino acid profile that rivals traditional whey. Purpose-built for protein-fortified foods, beverages, and dietary supplements, it is a high-performance, dairy-free alternative that delivers on both quality and nutrition.
How does YESTEIN® compare to whey protein?
YESTEIN® matches whey protein in PDCAAS (both score 1.0) and provides a complete amino acid profile, including at least 20% BCAAs. The primary distinction is that YESTEIN® is fully vegan and fermentation-derived, making it appropriate for plant-based product positioning where whey is not suitable. Whey digests faster, while YESTEIN® offers a more sustained release profile.
How does YESTEIN® compare to pea protein?
Compared to pea protein, YESTEIN® offers a higher protein quality score (PDCAAS 1.0 vs. approximately 0.82 for pea), a more complete essential amino acid profile, and a different flavor and texture profile. Pea protein is often limited in methionine and cysteine, while YESTEIN® meets all essential amino acid requirements without blending. Both can be used independently or in combination.
Can YESTEIN® be used in a blended protein system?
Yes. YESTEIN® works well alongside other proteins including pea, rice, soy, hemp, and whey. Blending offers several practical advantages. It can strengthen the overall amino acid profile of the system, improve texture and mouthfeel, and give formulators flexibility to hit protein content targets while managing cost and label positioning. With a PDCAAS of 1.0, it functions as a quality anchor in any blend, raising the overall protein quality of the system rather than diluting it.
Does NURA offer technical support for formulation and application development?
Yes. NURA provides technical application support to assist customers with formulation, processing guidance, sensory evaluation starting points, and documentation for regulatory and quality purposes. Technical support is available through the NURA innovation team.
What applications work best?
YESTEIN® performs across a wide range of food, beverage, and supplement formats. It is especially well suited for protein powders, bars, meal replacements, savory snacks, crackers, soups, and sauces, where its mild savory flavor profile and good dispersibility translate well into finished products. The NURA technical team can support application testing and formulation trials across any of these formats.
What does YESTEIN® taste like?
YESTEIN® has a mild savory protein profile that can work well in both savory and certain sweet applications, depending on the flavor system and use level. Final sensory performance will depend on the formulation, processing conditions, and target application.
How does YESTEIN® perform in terms of solubility and texture?
YESTEIN® disperses cleanly in powder and bar applications with no special handling required. A key functional advantage is its low viscosity, which keeps beverage and liquid applications smooth and easy to process, without the thickening or gelling issues common with some plant proteins.
Can YESTEIN® support GLP-1 or weight management trends?
Yes. GLP-1 users eat significantly less, creating a real nutritional gap around protein intake, muscle preservation, and satiety, and YESTEIN® is built to address all three. Its PDCAAS of 1.0 and complete essential amino acid profile support muscle protein synthesis, its slower digestion rate extends satiety, and its clean dispersibility and mild flavor make it easy to incorporate into the high-protein, low-volume bars, powders, and meal replacements this consumer is actively seeking.
Is YESTEIN® allergen-free?
Yes. YESTEIN® is free from all major recognized food allergens. It contains no milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, or soy, and is gluten-free. As a fermentation-derived yeast protein, it offers a clean allergen profile that simplifies label compliance and broadens the consumer base for finished products targeting allergy-conscious or restricted-diet markets.
