NutraBio built its reputation on full-disclosure labels and no proprietary blends, and that same philosophy carries over to its Clear Whey Protein Isolate. It’s one of the more budget-friendly clear whey options on the market, using a cold-processed isolate and third-party testing to back up its claims. Here’s whether the lower price comes with any real tradeoffs.

Quick verdict

NutraBio Clear Whey Isolate is a strong value pick in the clear whey category: 20 g of protein, under 80 calories, less than 1 g of carbs, and zero added sugar, all from a cold-processed WPI90 isolate that’s third-party tested and made without proprietary blends. At roughly $2 per serving it undercuts several bigger-name competitors while matching or beating them on transparency. The tradeoff is a smaller, less mainstream flavor lineup and a brand that’s less of a household name than Isopure or Ghost.

NutraBio Clear Whey Isolate at a glance

  • Protein type: Cold-processed, cross-flow ultra-microfiltered whey protein isolate (WPI90)
  • Protein per serving: 20 grams
  • Calories: Under 80 per serving
  • Carbs / sugar: Under 1 gram carbs, 0 grams added sugar
  • Flavors: Fruit Punch, Strawberry Lemonade, Blue Raspberry, Watermelon Breeze, Mango Mist, Pineapple Splash
  • Price checked: Approximately $42.99 per container (roughly $2 per serving based on a 20-serving tub)
  • Certifications: GMP certified facility, third-party batch tested, Kosher and Halal certified, made in the USA

What we like

  • Strong value. Roughly $2 per serving for 20 g of third-party-tested isolate is competitive with, and often cheaper than, bigger-name clear whey brands.
  • No proprietary blends, full label disclosure. NutraBio has built its whole brand identity around this, which is reassuring for anyone who’s been burned by vague “protein blend” labeling elsewhere.
  • Low calorie and low carb. Under 80 calories and under 1 g of carbs per serving is genuinely light, useful for anyone tracking intake closely.
  • Third-party tested. Independent batch testing adds a layer of quality assurance that not every clear whey brand offers.

What to consider

  • Smaller flavor lineup than bigger brands like Isopure, and less widely available in physical retail stores — mostly a direct-to-website and specialty-retailer product.
  • Less brand recognition. If you specifically want a name you already trust from decades of use, NutraBio is a newer entrant to this format than Isopure.
  • Servings per container can vary by listing — always check the current listing’s serving count before comparing price per serving, since retailers occasionally list different tub sizes.

How it compares

Gram for gram, NutraBio Clear Whey Isolate is priced competitively against Isopure Clear Protein while offering third-party testing that Isopure doesn’t advertise on this line. Isopure counters with more flavor variety and stronger name recognition. Both land at 20 g of protein per serving, which is on the lower end of the clear whey category — if maximizing protein per serving matters more to you than price or testing, it’s worth comparing against 25–28 g options as well.

Who it’s for

Good for: value-focused buyers who want third-party-tested clear whey without paying a premium for brand name, and anyone who prioritizes full ingredient transparency. Less ideal for: shoppers who want to buy in person at a big-box store, or who are chasing the highest possible protein-per-serving number.

Bottom line

NutraBio Clear Whey Isolate is one of the better value plays in the clear whey category — third-party tested, fully disclosed, low in calories and carbs, and competitively priced. It won’t win on flavor variety or brand recognition, but for anyone comparing clear whey purely on substance over marketing, it’s worth a look.
