Analysis

The 1,000 mg ingredient is calcium HMB, a compound used mainly for muscle maintenance rather than as a conventional calcium source. Only 140 mg elemental calcium is supplied, so it cannot close a large dietary calcium gap.

Muscle maintenance can indirectly support mobility and skeletal loading, but that differs from direct bone-mineral support. Vitamin D, vitamin K, magnesium, and collagen-matrix nutrients are absent.

The capsule fits users seeking HMB more than those shopping for calcium. The product name and compound weight should not be interpreted as providing 1,000 mg of elemental calcium.

Who is it for
  • Adults specifically seeking HMB
  • Users focused on muscle maintenance
  • People not relying on it for calcium repletion
Best for
  • HMB supplementation
  • Muscle-maintenance support
  • Indirect mobility support

Pros

  • Clearly states HMB compound amount
  • Discloses elemental calcium
  • Simple focused formula
  • Large capsule supply

Cons

  • Only 140 mg elemental calcium
  • Poor fit for primary bone support
  • No vitamin D
  • No magnesium or vitamin K

Nutrient quality

55 Moderate impact

Calcium HMB is intended mainly to deliver HMB rather than a conventional calcium source. The 140 mg elemental calcium amount is low for a dedicated supplement.

.

Ingredient transparency

81 Highest impact

Active ingredients generally have stated amounts and no proprietary blend hides the doses. Missing other ingredients and complete intake directions leave important label details unresolved.

.

Customer satisfaction

66 High impact

The supplied average rating is strong and the rating volume provides a useful aggregate signal. No comment-level evidence is provided to assess recurring complaints or confirm how experience matches the intended purpose.

.

Value for money

51 Moderate impact

The usable calcium contribution is weak for the product positioning. Format ingredients or non-calcium actives reduce its value for dedicated calcium use.

Calcium · 140 mg OverallScore63
D- Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyA+ Value

The small elemental calcium amount makes this a weak choice for primary calcium supplementation. Calcium is supplied through an HMB compound intended mainly to deliver HMB rather than a conventional calcium form. Label amounts are clear and the cost per serving is low, but those strengths do not address the limited calcium dose.
