Analysis

Each scoop supplies 25 g of whey protein isolate, a complete dairy protein suited to increasing daily protein intake and supporting recovery. The serving has 1 g of carbohydrate and 0 g of fat, keeping the macronutrient profile relatively lean.

Potassium at 179 mg and phosphorus at 67 mg contribute modest mineral amounts. Those nutrients do not make the powder a targeted heart product, and the formula does not address blood pressure, lipids, or vascular function directly.

The large container provides many servings for regular users. The supplied cholesterol unit appears implausible and should be checked against the package before use.

Who is it for
  • Adults seeking a lean complete-protein powder
  • Active people supporting recovery or daily protein intake
  • Users who prefer Dutch chocolate flavor
Best for
  • Increasing daily protein
  • Post-exercise or meal protein support
  • Low-carbohydrate whey isolate

Pros

  • Provides 25 g of complete protein
  • Keeps carbohydrate to 1 g per serving
  • Uses whey protein isolate
  • Sunflower lecithin may support mixing

Cons

  • Potassium amount is modest
  • Phosphorus amount is small for targeted use
  • Not designed around heart-support pathways
  • The large package supports repeated use but carries a premium serving cost

Warnings

  • Whey is milk-derived and is not appropriate for people with a milk-protein allergy.
  • People with lactose intolerance may still need to test tolerance because whey products can retain small amounts of lactose.
  • Anyone following a prescribed protein, phosphorus, or potassium restriction for kidney disease should account for the full serving.
  • The cholesterol entry uses an implausible gram unit in the supplied data; verify the package label rather than relying on that figure.

Nutrient quality

84 Highest impact

Whey isolate supplies a substantial, protein-focused serving with little carbohydrate or fat. A likely unit error in the cholesterol entry reduces confidence in the supplied label data.

Ingredient transparency

67 High impact

Most nutrient amounts are stated, but one implausible unit creates a material label inconsistency. Complete use directions and a full other-ingredients list are not included in the supplied facts.

Customer satisfaction

69 High impact

The supplied average rating is strong and the review volume is sufficient for a useful broad signal. No detailed comments are provided to assess repeated complaints or whether experiences match the intended use.

Value for money

71 High impact

A substantial protein serving provides fair value despite a middling recurring cost. Whey isolate quality helps justify the cost, though incomplete ingredient disclosure limits comparison.

Magnesium · 25 mg

The moderate potassium amount offers a limited contribution to vascular tone and sodium balance. Its chemical form is not disclosed, reducing confidence in its quality.

Small magnesium and mineral amounts add little cardiovascular depth. The formula is primarily a protein product rather than a targeted heart-health option.

Report overview
Potassium · 179 mg OverallScore31
F Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyF Value

The 179 mg potassium amount provides moderate support within a protein-focused formula. The missing chemical form prevents a confident assessment of absorption quality. The serving cost is relatively high for the moderate potassium contribution.

Phosphorus · 67 mg OverallScore30
F Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyF Value

The 67 mg phosphorus amount is below the preferred supplemental range and appears secondary to the whey protein. The label gives an exact amount but does not identify a phosphorus compound. A high serving cost further limits phosphorus-specific value.
