Analysis

A 27 g protein serving gives this powder strong protein density. Low fat, low carbohydrate, and no listed cholesterol make the macronutrient profile notably lean.

Sodium is modest, while potassium contributes only limited nutritional support. No additional active ingredient gives the formula meaningful breadth for the stated heart-health goal.

The supplied facts clearly show protein and key nutrients, but the protein source form and inactive ingredients are not identified. That prevents fuller assessment of processing, flavoring, sweeteners, and tolerance.

Who is it for
  • Adults wanting a high-protein powder
  • People limiting fat and carbohydrate
  • Users without dairy or peanut-related allergies
Best for
  • Post-training protein
  • Lean daily supplementation
  • High-protein shakes

Pros

  • Provides 27 g protein
  • Contains very little fat
  • Has no listed cholesterol
  • Keeps sodium modest

Cons

  • Protein source form is unclear
  • Inactive ingredients are missing
  • Potassium is modest
  • Heart-health support is indirect

Warnings

  • The chocolate-peanut-butter flavor may be unsuitable for people with peanut allergy unless the full label confirms otherwise
  • A likely dairy protein base should be checked by users with milk allergy
  • Missing inactive ingredients prevent complete allergen screening

Nutrient quality

89 Highest impact

A substantial complete-protein amount provides the main nutritional strength. Unspecified protein and mineral forms plus limited heart-specific design reduce confidence in quality and intended-use fit.

Ingredient transparency

66 High impact

Protein and basic nutrition totals are clear enough to judge the main serving. Missing source ingredients, mineral forms, full directions, and non-active ingredients prevent complete label assessment.

Customer satisfaction

72 High impact

The supplied average is strong and supported by substantial response volume. No comment-level evidence is available to assess repeated complaints or alignment with the intended use.

Value for money

76 High impact

A substantial complete-protein serving provides practical nutritional value. Incomplete source disclosure and weak heart-specific utility limit the quality case at the stated category cost.

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

The sodium amount is inadequate for strenuous exercise and its mineral source is not disclosed. Potassium offers some breadth but lacks a stated form, while magnesium and buffering compounds are missing. Low carbohydrate content helps, yet the high serving cost buys protein rather than effective electrolyte replacement.

Potassium · 180 mg OverallScore29
F Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyF Value

The 180 mg potassium serving makes a modest contribution but falls well short of the collection benchmark. The unidentified potassium source prevents a clear assessment of absorption quality. Its serving cost is somewhat favorable, yet the low potassium amount keeps value limited.
