Analysis

One scoop supplies 19 g of whey protein concentrate, 2 g of fat, and 1 g of carbohydrate. Whey concentrate is a complete protein but generally retains more milk components than isolate.

Vitamin C at 115 mg is substantial, while 110 mg of potassium and 110 mg of phosphorus add modest mineral support. A 70 mg enzyme blend is disclosed, though the individual enzymes and their activities are not provided.

The unflavored version avoids added flavoring and offers a longer supply for food or shake use. It works better as a general protein powder than a heart-health product because it supplies 60 mg of cholesterol and does not target lipids, vascular tone, or blood pressure.

Who is it for
  • Adults seeking a moderate complete-protein serving
  • People who tolerate whey concentrate
  • Users who value an added enzyme blend
Best for
  • General daily protein intake
  • Shake or food use
  • Protein plus vitamin C

Pros

  • Provides 19 g of complete protein
  • Includes 115 mg of vitamin C
  • Lists an added enzyme blend
  • Clearly states major mineral amounts

Cons

  • 60 mg of cholesterol per serving
  • Protein amount is lower than many isolate powders
  • Enzyme activities are not disclosed
  • Potassium and phosphorus are incidental rather than targeted

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.

Nutrient quality

85 Highest impact

Whey concentrate supplies a meaningful protein serving with useful food-derived minerals. Mineral compounds are not identified, so their form quality cannot be judged.

Ingredient transparency

75 High impact

Principal nutrient amounts are stated clearly and no proprietary blend hides the protein serving. Complete use directions and a full other-ingredients list are not included in the supplied facts.

Customer satisfaction

72 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

72 High impact

A substantial protein serving provides fair value despite a middling recurring cost. Whey concentrate is less refined than isolate, and incomplete ingredient disclosure weakens comparison.

Report overview
Phosphorus · 110 mg OverallScore44
F Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyF Value

The phosphorus amount falls within a targeted supplemental range, but its source compound is not disclosed. One scoop is practical, while the milk-derived whey is unsuitable for people with a milk allergy. The high cost per serving weakens its value as a phosphorus source.

Potassium · 110 mg OverallScore33
F Active Ingredient Quality & BioavailabilityD Dose, Safety & Label TransparencyF Value
Potassium comes from a food-based powder, but the chemical form is not disclosed. The elemental potassium amount is low and falls well below the collection median. The small potassium contribution does not compare well with the recurring cost. The broader whey protein may still provide value beyond potassium alone.
