Analysis

A 25 g hydrolyzed whey-isolate serving offers complete protein in a lean package. The low calorie, fat, and carbohydrate profile suits users who want protein without a meal-replacement format.

Sodium and cholesterol stay relatively modest, which may help some users comparing whey products. Potassium is low and the formula does not include a meaningful heart-focused active.

Clear identification of hydrolyzed isolate is helpful, but the supplied label data stops short of listing inactive ingredients. Flavoring, sweeteners, and other tolerance-related details therefore remain unknown.

Who is it for
  • Adults seeking fast-mixing whey isolate
  • People limiting fat and carbohydrate
  • Users without dairy allergy
Best for
  • Post-training protein
  • Lean daily protein intake
  • Simple high-protein shakes

Pros

  • Delivers 25 g protein
  • Contains no listed fat
  • Keeps carbohydrates minimal
  • Uses hydrolyzed isolate

Cons

  • Contains little potassium
  • Inactive ingredients are undisclosed
  • Value per serving is limited
  • Offers no focused cardiovascular ingredient

Warnings

  • Milk-allergic users should avoid whey isolate
  • Hydrolysis does not make whey safe for a dairy-protein allergy
  • Missing sweetener and flavor details may matter to sensitive users

Nutrient quality

87 Highest impact

A lean, substantial protein dose provides useful nutritional depth. Missing source detail and very low electrolyte amounts leave the formula narrow for the configured purpose.

Ingredient transparency

65 High impact

Protein and basic nutrition totals are clearly stated. Missing protein source, mineral forms, preparation guidance, and non-active ingredients leave important disclosure gaps.

Customer satisfaction

72 High impact

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

Value for money

60 Moderate impact

A substantial lean protein dose provides useful serving value. High category cost and incomplete source disclosure weaken competitiveness.

Report overview
Sodium · 100 mg OverallScore51
D Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyD+ Value

The 100 mg sodium serving is too low for robust replacement during intense or prolonged exercise. The sodium source is not identified, which limits confidence in mineral quality. Its serving cost is relatively high for a formula aimed mainly at broader nutrition or performance rather than hydration.

View ingredientView products
Potassium · 100 mg OverallScore30
F Active Ingredient Quality & BioavailabilityD Dose, Safety & Label TransparencyF Value

The potassium appears to come from food ingredients, but its chemical form is not identified. The 100 mg amount is low, and the label does not fully separate compound weight from elemental yield. Potassium-focused value is poor at this serving cost, so the broader protein powder must justify the purchase.
