Analysis

The 100-calorie serving delivers 25 g protein with no fat or carbohydrate. Calcium, potassium, magnesium, phosphorus, and added vitamins provide more micronutrient coverage than a basic isolate.

Sodium at 240 mg is reasonable for many active users but does not make the powder specifically heart focused. Most vitamin and mineral forms are not identified, limiting assessment of quality.

It suits users who prioritize very lean protein and creamy vanilla flavor. The small package is better for trial use than ongoing supplementation.

Who is it for
  • Adults seeking zero-carb protein
  • Users watching calorie intake
  • People trying a vanilla whey isolate
Best for
  • Lean protein intake
  • Low-carbohydrate diets
  • Post-activity protein

Pros

  • Provides 25 g protein
  • Zero carbohydrate and fat
  • Only 100 calories
  • Includes calcium, potassium, and magnesium

Cons

  • Only fifteen servings
  • Most nutrient forms are unspecified
  • Contains 240 mg sodium
  • Heart-health positioning is indirect

Warnings

  • Whey protein is milk-derived and unsuitable for milk-protein allergy
  • People with kidney-related mineral restrictions should account for the potassium and phosphorus content

Nutrient quality

71 High impact

The substantial protein serving and useful amounts of calcium, potassium, and phosphorus support general nutrition. Unspecified vitamin and mineral forms limit absorption confidence, and the profile is only indirectly aligned with heart health.

Ingredient transparency

73 High impact

Specific amounts are shown for the protein, vitamins, and minerals, with no hidden active blend. Most ingredient forms, daily-use directions, and inactive ingredients are not fully supplied.

Customer satisfaction

72 High impact

The aggregate rating is strong and supported by a meaningful review count. No specific review comments were supplied, so repeated complaints and purpose-related experiences cannot be verified.

Value for money

74 High impact

The meaningful protein dose supports practical value in each serving. Broad micronutrient coverage helps, though incomplete form details keep the formula from leading its category.

Potassium at 370 mg and magnesium at 100 mg give the fortified protein powder some cardiovascular relevance. The protein format is not designed as a focused heart supplement.

The potassium and magnesium forms are not identified, which limits assessment of absorption and functional quality. Low-dose B vitamins, vitamin K, and selenium add general fortification without meaningful cardiovascular depth.

Report overview
Sodium · 240 mg OverallScore67
D Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyB- Value

The sodium source and supporting mineral forms are not fully identified, limiting confidence in ingredient quality. The sodium amount fits the lower replenishment band rather than the preferred range. The higher serving cost is partly explained by substantial non-electrolyte nutrition.

View ingredientView products
Chloride · 360 mg OverallScore54
D- Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyF Value

The chloride amount is meaningful for electrolyte support. The source salt is not identified, leaving a notable transparency gap. The dissolvable delivery is practical, but the serving cost is high.

View ingredientView products
Calcium · 340 mg OverallScore49
F Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyF Value

The exact calcium form is not disclosed, preventing an absorption-quality assessment. The 340 mg calcium amount offers a useful supplemental dose below the single-dose absorption ceiling. Protein is the main value of the powder, while its high serving cost makes it inefficient as a calcium supplement.
