NutraBio Classic Whey: 100% Pure WPC80 — Clean, Creamy, Tried & True Since 1996 NutraBio Classic Whey is the protein powder that started it all — a 100% pure Whey Protein Concentrate (WPC80) that has been formulated the same honest way since 1996 without ever being amino spiked, diluted with inferior protein sources, or compromised with fillers, maltodextrin, dextrose, or excipients of any kind. Two decades ago, NutraBio launched a protein so straightforward and transparent that it set the standard the rest of the industry is still trying to meet. Today, it carries the name it earned: Classic Whey. Each 33.46g scoop delivers 25 grams of complete protein sourced entirely from WPC80 — the highest-quality grade of Whey protein concentrate, cross-flow micro- and ultra-filtered to preserve the full natural nutrient matrix, including naturally occurring healthy fats, carbohydrates, immunoglobulins, and bioactive fractions. The result is a richer, creamier shake experience than Whey isolate, with an elite macronutrient profile at 130 calories per serving and award-winning flavors backed by full label transparency. Non-GMO, Kosher Dairy-certified, BSE/TSE-free, and third-party tested — batch-level. This is the protein that never compromises.

These inferior concentrates deliver as little as 34–60% protein by dry weight, padded out with excessive lactose, fat, and fillers. WPC80 is an entirely different tier. At a minimum 80% protein by dry weight, WPC80 is only 10% lower in protein density than the elite WPI90 isolate — while retaining the full natural nutrient matrix that ultrafiltration removes. That natural matrix includes small amounts of healthy fats, immunoglobulins, lactoferrin, and a complete spectrum of bioactive Whey fractions that support immune function, gut health, and muscle recovery. NutraBio's WPC80 is cross-flow micro- and ultra-filtered using a cold-process method that preserves all of these naturally occurring fractions without heat denaturing the protein's native structure. NutraBio Classic Whey contains only WPC80 — no other grade, no blending, no dilution. Not WPC34. Not WPC60. Not sweet Whey. Not a blend of cheaper concentrates marketed as "100% Whey." Just WPC80, fully disclosed, at the exact amount listed on the label. Classic Whey (WPC80) vs. NutraBio Whey Protein Isolate (WPI90) NutraBio offers both WPC80 (Classic Whey) and WPI90 (Whey Protein Isolate) — and they are genuinely different products suited to different goals and protocols. Neither is universally "better" — the right choice depends on what you're optimizing for: Feature Classic Whey (WPC80) Whey Protein Isolate (WPI90) Protein per scoop 25g 25g Calories 130 110 Total fat 2g 0g Total carbohydrates 2g 1g Cholesterol 95mg (31% DV) 3mg (1% DV) Lactose ~97% lactose-free ~99.5% lactose-free Natural bioactive fractions ✅ Preserved (natural fat matrix intact) Largely removed in filtration Texture/mouthfeel Richer, creamier, thicker Lighter, cleaner, more watery Amino spiking ✅ None — verified by 3rd party ✅ None — verified by 3rd party Processing CFM cross-flow micro + ultrafiltration CFM cross-flow ultrafiltration Best for Bulking, general use, maximizing Flavor/creaminess, budget-conscious Cutting, lactose sensitivity, strict macros, keto Kosher certified ✅ Kosher Dairy ✅ Kosher Dairy Price point More economical per gram of protein Premium pricing Nutrition Facts Supplement Facts Serving Size: 1 Scoop (33.46g) Nutrient Amount Per Serving % Daily Value Calories 130 Total Fat 2g 3% Saturated Fat 1g 6% Trans Fat 0g Cholesterol 95mg 31% Sodium 120mg 5% Total Carbohydrate 2g
