Analysis

The isolate supplies 25 g protein in a lean serving, making it well suited to users who want protein without much carbohydrate or fat. Sunflower lecithin supports mixing without changing the main nutritional role.

Potassium, magnesium, and phosphorus occur at modest food-level amounts rather than targeted supplemental doses. The product therefore supports general nutrition and muscle maintenance, not lipid management, vascular tone, or cardiac energy.

The supplied cholesterol entry uses an implausible unit and should be checked against the package before purchase. Ingredient disclosure beyond the isolate and lecithin is not complete enough to assess all flavoring and sweetener choices.

Who is it for
  • Adults seeking lean protein
  • Users who prefer whey isolate
  • People wanting a large protein-powder supply
Best for
  • General protein intake
  • Post-exercise nutrition
  • Muscle maintenance

Pros

  • Provides 25 g complete protein
  • Very low carbohydrate
  • Uses whey isolate
  • Includes sunflower lecithin for mixing

Cons

  • Not designed for heart support
  • Mineral amounts are modest
  • Non-active ingredients are incompletely supplied
  • Cholesterol data appear inconsistent

Warnings

  • Contains milk-derived whey and is unsuitable for people with a milk-protein allergy.
  • The supplied cholesterol unit appears inconsistent with a nutrition label and should be verified on the package.

Nutrient quality

77 High impact

Whey isolate provides a substantial amount of complete protein in a lean format. The implausible cholesterol entry and unnamed mineral forms reduce safety and form confidence.

Ingredient transparency

63 Moderate impact

The whey source and main nutrient amounts are disclosed without a hidden protein blend. The cholesterol unit, mineral forms, directions, and full non-active ingredient list remain unclear.

Customer satisfaction

64 Moderate impact

The aggregate rating is favorable but the response base is modest. No review text is supplied, so repeated complaints and specific product experiences cannot be verified.

Value for money

77 High impact

The substantial protein serving gives the formula useful practical value. The ongoing cost and incomplete label detail keep it from being a clear category leader.

Magnesium · 22 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
Sodium · 102 mg OverallScore58
D Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyB- Value

The sodium dose is clearly stated but too small for meaningful athletic replenishment. Potassium and magnesium broaden the mineral profile, though their forms and the sodium source remain unspecified. Low carbohydrate content limits additive concerns, while the protein-isolate format makes the serving cost high for hydration alone.

Potassium · 158 mg OverallScore31
F Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyF Value

The 158 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 · 63 mg OverallScore30
F Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyF Value

The 63 mg phosphorus amount is likely incidental to the whey protein and is below a meaningful targeted range. Elemental quantity is clear, but no phosphorus compound is identified. The high serving cost makes it inefficient for someone primarily seeking phosphorus.
