Analysis

The 27 g protein serving comes with only 0.5 g fat, 2 g carbohydrate, and no listed cholesterol. That lean profile can suit shoppers prioritizing protein density.

Potassium at 180 mg is too small to provide meaningful targeted electrolyte support. Sodium is also low for exercise hydration, and no ingredients specifically support lipids, vascular tone, or cardiac energy.

The nutrition panel is clearly quantified, but the supplied data do not identify the isolate source details, mineral forms, or other ingredients. Only 30 servings and a high serving cost reduce its value despite the lean composition.

Who is it for
  • Adults seeking a lean protein powder
  • People limiting carbohydrate and fat
  • Users who value a cholesterol-free listed serving
Best for
  • Protein-dense shakes
  • Post-workout protein intake
  • Lower-carbohydrate nutrition

Pros

  • Provides 27 g protein
  • Contains only 2 g carbohydrate
  • Lists no cholesterol
  • Very low fat per serving

Cons

  • Only 180 mg potassium
  • High serving cost
  • Mineral forms are not identified
  • Complete ingredient list is not supplied

Warnings

  • Whey isolate is milk-derived and is unsuitable for people with a milk allergy
  • The 120 mg sodium amount is not sufficient for substantial sweat replacement
  • The supplied label does not show sweeteners or flavoring ingredients, which limits screening for individual sensitivities

Nutrient quality

86 Highest impact

The protein amount is meaningful and the macronutrient profile is practical. Incomplete whey-source detail and weak heart-specific coverage are the main limitations.

.

Ingredient transparency

72 High impact

Core nutrition totals are clear enough for basic comparison. Missing complete ingredients, use directions, and detailed protein or blend composition leave notable gaps.

.

Customer satisfaction

69 High impact

Aggregate satisfaction data are favorable. Specific firsthand comments were not supplied, leaving repeated complaints and purpose fit uncertain.

.

Value for money

71 High impact

The protein amount provides fair value for the category. Cost and formulation trade-offs keep it from standing out.

Report overview
Sodium · 120 mg OverallScore52
D Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyD+ Value

The sodium serving is too small for demanding sweat replacement. Potassium adds some electrolyte breadth, but its form and the sodium source are not identified. The protein-focused formula offers only middling value for a dedicated hydration goal.

Potassium · 180 mg OverallScore31
F Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyF Value

The potassium amount offers only moderate support and remains well below the collection median. Its chemical form is undisclosed, making quality and metabolic utility unclear. A near-median serving cost is difficult to justify for potassium-focused use.
