NutraBio - Natural Whey Protein Isolate

NutraBio Natural Whey Protein Isolate delivers 25 grams of pure, complete protein per serving from a single, high-quality source — no artificial ingredients, no added sugars, and nothing to hide. It starts with cold-processed, cross-flow microfiltered WPI90, one of the purest and most complete protein sources available. This filtration process removes excess fat, lactose, and impurities without the use of harsh chemicals, preserving the protein's natural integrity and full amino acid profile. The result is 25g of complete protein, 5.3g of naturally occurring BCAAs, 11.7g of EAAs, and 2.6g of leucine per serving, at just 120 calories, zero added sugar, and zero fat. Every flavor is sweetened with Stevia Leaf Extract and flavored with natural flavors only — no artificial flavors, colors, or sweeteners anywhere in the formula. Mix 1 scoop with 6oz of cold water and adjust to your preferred consistency. Made in the USA. Third-party tested on every batch. Available in Creamy Vanilla, Gourmet Chocolate, and Strawberry Ice Cream.†

Cold Cross-Flow Microfiltration — Why This Process Matters

Not all protein sources are created equal, and not all protein products are made with the transparency your body deserves. Natural Whey Protein Isolate starts with cold-processed, cross-flow microfiltered WPI90 — a filtration method that removes excess fat, lactose, and impurities without relying on harsh chemical processing. This gentler filtration preserves the protein's natural molecular integrity and full amino acid profile, rather than denaturing it the way more aggressive filtration or ion-exchange methods can. The "90" in WPI90 reflects that at least 90% of the finished powder's content is pure protein, with minimal residual fat and carbohydrate — meaning very little of each scoop is filler.†

Truly Natural — No Artificial Flavors, Colors, or Sweeteners

NutraBio Natural Whey Protein Isolate is flavored with natural flavors and sweetened with Stevia Leaf Extract. There are no artificial flavors, no artificial colors, and no artificial sweeteners anywhere in the formula, making it one of the cleanest natural protein options available. This is a genuinely different formulation approach from most whey isolate products on the market, which typically rely on Sucralose or Acesulfame Potassium for sweetness — NutraBio's stevia-only approach reflects the brand's broader clean-label positioning.†

2.6g Leucine — The Muscle Protein Synthesis Trigger

Leucine is the specific branched-chain amino acid that directly activates the mTOR pathway — the primary cellular signaling cascade responsible for initiating muscle protein synthesis. At 2.6g of naturally occurring leucine per serving, Natural Whey Protein Isolate provides a dose within the range most commonly associated with maximizing this signal, without requiring any added, isolated leucine beyond what the whey protein itself naturally contains.†

120 Calories, Zero Fat, Zero Added Sugar — Built for Lean Nutrition Goals

With 25 grams of protein, zero fat, zero added sugars, and only 120 calories per serving, Natural Whey Protein Isolate supports lean body composition goals by helping you stay fuller longer, preserve muscle during a calorie deficit, and maintain a healthy metabolism. Protein is the most satiating macronutrient, meaning this formula's high protein-to-calorie ratio makes it a particularly efficient choice for anyone managing daily calorie intake while still prioritizing adequate protein.†

NutraBio's Quality Standard — Full Transparency, Every Batch Tested

Fully transparent labels, no proprietary blends, and third-party testing on every batch — so you always know exactly what you're getting. NutraBio's own comparison highlights specific advantages over many competing brands: 100% premium WPI90 protein (not always included elsewhere), cold cross-flow micro- and ultra-filtration (not always included elsewhere), and third-party batch testing (not always included elsewhere) — while naturally sweetened flavoring and easy digestibility are shared standards across quality brands in the category.†
