Product analysis
Calcium Citrate Mini-Tablets combines calcium with vitamin D to help fill low intake and support normal bone mineral formation.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality42
Calcium uses a favorable citrate form for absorption. Several other ingredient descriptions lack preparation details, limiting comparison of the full formula.
Ingredient Transparency78
All declared amounts are disclosed, making servings easier to check. Calcium and vitamin D forms are named, while some supporting ingredient forms are not consistently specified.
Value For Money35
Calcium offers moderate value at the serving price. Boron is relatively costly for the amount supplied, while value for the other supporting ingredients remains uncertain.
Customer Satisfaction64
Customer ratings are positive. The small review base limits how broadly that feedback can be applied.
Product Focus88
Calcium and vitamin D support bone mineral formation and can help address low intake. Added horsetail and boron have less clear benefits for bone strength.

Calcium · 800 mgVitamin D · 20 mcgBoron · 2.4 mg
Calcium supplies bone mineral and vitamin D supports absorption and normal mineralization, helping address low intake. The 800 mg calcium serving contributes mineral, while 20 mcg vitamin D matches a nutritional reference rather than establishing routine fracture prevention. Horsetail does not establish the defined silicon preparation studied for bone markers, and boron's mineral-metabolism rationale does not demonstrate a reliable bone-density benefit.
How this product is rated for Bone Health
Ingredient fit83
Relevant bone nutrients sit within a broader formula, with some small or unresolved contributions. The serving receives partial recognition against the saved amount references, without representing a minimum effective dose.
Goal fit
Relevant bone nutrients sit within a broader formula, with some small or unresolved contributions.
Dose adequacy
The serving receives partial recognition against the saved amount references, without representing a minimum effective dose.
Pathways80
The strongest saved contribution concerns calcium absorption and regulation. The saved breadth finding covers mineral supply and calcium absorption.
Depth
The strongest saved contribution concerns calcium absorption and regulation.
Breadth
The saved breadth finding covers mineral supply and calcium absorption.
Evidence100
Calcium leads the saved evidence finding for nutritional mineral supply; fracture outcomes are mixed.
Evidence strength
Calcium leads the saved evidence finding for nutritional mineral supply; fracture outcomes are mixed.
Studied preparation
The saved finding recognizes the qualifying preparation declarations, without demonstrating superior bone outcomes for their forms.
Formulation logic100
The credited nutrients can contribute alone or have the required partner present. All credited ingredients meet the saved minimum amount criterion, which is not a proven fracture-prevention threshold.
Partner coverage
The credited nutrients can contribute alone or have the required partner present.
Conflicts
No listed ingredient conflict was triggered by the supplied facts.
Effective doses
All credited ingredients meet the saved minimum amount criterion, which is not a proven fracture-prevention threshold.

Calcium (Calcium Citrate) · 800 mg OverallScore64
Each serving provides 800 mg of calcium from calcium citrate, a large amount to take at once. The evaluation identifies a flow agent, and a whole-product serving costs about $0.57.
How this ingredient is rated
Active Ingredient Quality & Bioavailability86
The declared calcium amount is clear, and calcium citrate is the identified source.
Calcium Form & Absorption Potential
Calcium citrate is the identified calcium source.
Elemental Calcium Transparency
The declared 800 mg is the calcium amount per serving.
Dose, Safety & Label Transparency48
A large amount of calcium in one serving may be absorbed less efficiently, and a flow agent is identified.
Absorption-Optimized Serving Dose
A serving supplies 800 mg of calcium; absorption may be less efficient with such a large amount at once.
Formulation Purity & Additives
A flow agent is identified in the evaluation; the saved facts do not name it.
Value50
About $0.57 per whole-product serving falls in the middle of the evaluated prices.
Price Per Serving Efficiency
About $0.57 per whole-product serving falls in the middle of the evaluated prices.
Boron · 2.4 mg OverallScore60
Horsetail · 40 mg OverallScore29
