Analysis

The capsules combine 300 mg of calcium, 150 mg of magnesium, and 3 mcg of vitamin D3. Those amounts provide balanced general mineral support without forcing an oversized calcium dose.

Calcium citrate and magnesium glycinate improve the blend, while calcium carbonate and magnesium oxide are less consistently absorbed. The supplied data repeats the same elemental amounts under both forms, so the exact form split is unclear.

Two capsules per serving offer practical dosing and good value. The vitamin D3 contribution is small, and vitamin K is absent, so the formula is useful but not complete for broad bone support.

Who is it for
  • Adults seeking moderate calcium and magnesium together
  • People who want to avoid a very large calcium dose
  • Users who prefer a two-capsule serving
Best for
  • General calcium and magnesium supplementation
  • Moderate mineral gap coverage
  • Users prioritizing balanced doses over maximum potency

Pros

  • Pairs calcium with 150 mg of magnesium
  • Includes citrate and glycinate forms
  • Uses a manageable 300 mg calcium amount

Cons

  • Also relies on carbonate and oxide forms
  • Duplicate entries obscure the exact form split
  • Vitamin D3 is modest and vitamin K is absent

Warnings

  • Magnesium oxide may cause loose stools or stomach discomfort in sensitive users.

Nutrient quality

90 Highest impact

Useful calcium and magnesium amounts pair with supportive vitamin D3. Carbonate and oxide make the otherwise favorable form profile less consistent.

Ingredient transparency

78 High impact

All active totals are disclosed without a proprietary blend. Individual form contributions, full directions, and inactive ingredients remain unclear.

Customer satisfaction

66 High impact

The aggregate rating is exceptionally favorable despite a modest evidence base. Specific experience details are unavailable, leaving complaint patterns and purpose fit uncertain.

Value for money

89 Highest impact

Balanced mineral dosing and a reasonable serving cost support good value. Mixed forms keep it below the strongest category options.

B Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyB+ Value

A citrate-and-carbonate blend improves on carbonate alone but does not match a fully chelated form, while the 300 mg amount supports general supplementation but may not cover high needs alone. The elemental amount is clear, and no artificial color, sweetener, or whitening agent appears in the supplied ingredients. The serving provides good value relative to the collection median.
