Analysis

The serving provides 24 g casein protein and 580 mg calcium, making it well aligned with slow-release protein and bone-mineral intake. Only 0.5 g fat and a moderate calorie count keep the macro profile reasonably lean.

Nine grams of carbohydrate and 180 mg sodium are manageable but higher than some isolates. Potassium is modest, and the product does not contain dedicated cardiovascular actives.

It fits users who want a filling protein before a long gap between meals or overnight. Milk allergy and individual tolerance to casein are the main practical screens.

Who is it for
  • Adults seeking slow-digesting protein
  • Users prioritizing calcium intake
  • People wanting an evening protein option
Best for
  • Slow-release protein
  • Bone-support nutrition
  • Between-meal satiety

Pros

  • Provides 24 g casein protein
  • Includes 580 mg calcium
  • Low fat
  • Low serving cost

Cons

  • Contains 9 g carbohydrate
  • Moderate sodium
  • Only modest potassium
  • No targeted heart ingredients

Warnings

  • Casein is milk-derived and unsuitable for milk-protein allergy
  • The high calcium serving should be counted when combining with calcium supplements
  • People with kidney-related protein or phosphorus restrictions should review use individually

Nutrient quality

81 Highest impact

The substantial casein serving and high calcium amount strongly support protein intake and bone health. Heart-health alignment is indirect, and most nutrient forms are unspecified.

Ingredient transparency

75 High impact

Macronutrient and mineral amounts are stated with no hidden active blend. Detailed casein composition, directions, and inactive ingredients are not supplied.

Customer satisfaction

71 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

92 Highest impact

A substantial casein dose and high calcium content provide strong utility per serving. The practical recurring cost compares favorably within the protein category.

Calcium · 580 mg

Casein protein supports the organic bone matrix, while 580 mg calcium supplies structural mineral and potassium adds modest acid-balance support. The combination covers both flexible protein framework and hard mineral matrix with strong nutritional evidence.

The protein and calcium amounts are substantial, though the calcium chemical source is not identified. The formula is coherent for bone and muscle nutrition, with sodium and flavoring components adding only limited distraction.

Report overview
Sodium · 180 mg OverallScore60
D- Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyA+ Value

The sodium amount is modest for intense activity and is better suited to lighter use. The sodium source is not identified, which limits confidence in its purity and functional form. Its low serving cost provides strong practical value.

Calcium · 580 mg OverallScore56
F Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyF Value

Calcium reaches an absorption-friendly amount, but the undisclosed chemical form prevents judging how efficiently it may be absorbed. No targeted controversial additive is shown in the supplied details. The high serving cost and protein-focused design make it a weak choice when calcium is the main goal.

View ingredientView products
Potassium · 220 mg OverallScore44
F Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyC- Value
Potassium comes from a food-based powder, but the chemical form is not disclosed. The elemental potassium amount is moderate but remains below the collection median. The moderate potassium contribution is reasonably economical within a broader nutrition powder. The broader casein protein may still provide value beyond potassium alone.
