Affordable calcium citrate is the clear strength of this simple tablet. Vitamin D3 is lightly dosed, so it works better as a calcium top-up than as a complete vitamin D or bone formula.

Analysis

The tablet provides 315 mg of calcium as citrate, a useful form for people who want a moderate supplemental amount. Vitamin D3 is clearly identified as cholecalciferol, but 200 IU contributes only modestly.

A two-ingredient active profile is easy to understand and avoids unnecessary additions. It also means the product offers little beyond calcium, and no fat carrier is shown for the vitamin D3.

One tablet per listed serving and a low cost make the formula practical for topping up dietary calcium. Full excipients and daily directions are not supplied, so users still need the retail label to assess fit.

Who is it for
  • Adults needing a moderate calcium top-up
  • Users who prefer calcium citrate
  • People seeking a simple low-cost formula
Best for
  • Calcium citrate intake
  • A small active-ingredient list
  • Budget-friendly maintenance support

Pros

  • Uses calcium citrate
  • Clearly identifies vitamin D3 as cholecalciferol
  • Provides a moderate calcium amount
  • Uses a convenient one-tablet serving

Cons

  • Vitamin D3 is supplied at only 200 IU
  • No fat carrier is shown
  • Full excipients are not provided
  • The formula offers limited nutrient breadth

Warnings

  • Calcium can reduce absorption of levothyroxine, iron, and some antibiotics; follow the specific spacing instructions for those products.
  • People with recurrent calcium-based kidney stones or high blood calcium should confirm whether extra calcium is appropriate.
  • Calcium citrate can still cause constipation, nausea, or bloating in sensitive users.

Calcium (Calcium Citrate) · 315 mg OverallScore87
A- Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyA+ Value

Calcium citrate offers reliable absorption even when stomach acid is low. The 315 mg serving provides a useful amount but may require another daily dose for higher needs. Calcium can reduce absorption of levothyroxine and tetracycline or quinolone antibiotics, so doses should be separated.

Vitamin D (Cholecalciferol) · 200 IU OverallScore51
B- Active Ingredient Quality & BioavailabilityD- Dose, Safety & Label TransparencyF Value

The preferred D3 form is present, but its amount is too small for a strong standalone vitamin D option. The dry caplet has no stated lipid carrier, and the D3 source is not identified. Calcium may be useful for shoppers seeking both nutrients, yet the vitamin D efficiency and verification evidence remain weak.
