THE PROTEIN THAT WORKS AS HARD AS YOU DO
Day One ISOLATE is a high-protein, low-carbohydrate, low-fat formula with an absorption rate that outperforms even Whey Protein Isolate (WPI).
Crafted with hydrolyzed NiHPRO® protein isolate and 100% free from dairy and lactose, it delivers fast, efficient protein uptake without the digestive drag. Fortified with advanced digestive enzymes and 7 billion CFU of gut-supporting probiotics, ISOLATE sets a new benchmark in protein absorption, gut health, and recovery. From digestion to muscle repair, ISOLATE keeps working long after your shaker is empty.
Each serve delivers 25g of high-purity protein with clinical-grade absorption, zero allergens, and a rich, satisfying texture. ISOLATE supports faster recovery, deeper satiety, and better gut health in one clean, uncompromising formula. Whether you’re training hard, eating clean, or simply demanding more from your fuel, ISOLATE is built to elevate performance—inside and out.
WHY USE DAY ONE ISOLATE?
Advanced Digestion & Uptake
ISOLATE uses multi-phase protease enzymes that stay active across all pH levels—breaking down protein from stomach to small intestine for full absorption. It also includes 7 billion CFU from Weizmannia coagulans, L. plantarum, and B. subtilis to improve digestion, nutrient uptake, immune function, and gut balance. The result: more usable protein, less waste, and no digestive drag.
Superior Protein Quality
Each serve delivers 25g of protein with 85%+ purity (dry basis) and 80.87% as-is, verified by third-party testing. With 1.0 PDCAAS and 116 DIAAS, ISOLATE ranks among the highest-quality proteins available. It’s rich in leucine and EAAs, helping drive muscle growth and recovery.
Delicious flavours & Creamy texture
ISOLATE shakes are naturally thick, creamy, and smooth—designed to keep you full, without grit or bitterness. Its indulgent texture and flavours (Vanilla Custard Slice, Strawberry Sundae, Spiced Caramel Biscuit) make it a protein you’ll actually enjoy, every day.
Gut-Friendly & Allergen-Free
ISOLATE is 100% free from dairy, lactose, soy, gluten, and all top 24 allergens. It’s also FODMAP-friendly and non-GMO—clean, safe, and ideal for anyone with sensitivities or gut concerns. No bloating, no compromise.
Unmatched Transparency & Testing
We list protein content on an “as-is” basis—no inflated dry-weight numbers. Every batch is third-party tested, and through our Check My Batch program, you can verify the protein and amino profile of your exact tub. Transparency is standard, not optional.
Low Impact. High Integrity.
ISOLATE is produced using MPi™ hydrolyzation and has a lower carbon footprint than dairy or soy proteins. Manufactured in globally certified facilities, it delivers on quality without compromising the planet.
ISOLATE isn’t just another protein—it’s the next evolution of performance nutrition. Built for those who train with purpose, fuel with intention, and demand more from every scoop, ISOLATE goes beyond macros to deliver real-world results backed by real-world science. It’s clean. It’s complete. And it’s trusted by those who know that greatness isn’t found in shortcuts—it’s earned through consistency, effort, and the right tools.
