Product analysis
Vegan Plant-Based Calcium 1000 mg offers a vegan way to add calcium, with vitamin D supporting its absorption when intake is low. Unnamed blend ingredients make the complete formula harder to assess.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality38
Vitamin K is clearly identified as MK-7, while calcium and silicon absorption quality remains uncertain. The mineral source names do not establish the specific forms the body receives.
Ingredient Transparency77
All listed amounts and most source forms are disclosed. The unnamed blend contents leave part of the formula unclear.
Value For Money34
The serving cost is relatively high when considered for calcium or vitamin K. Silicon and vanadium comparisons are moderate, while the remaining comparisons are uncertain.
Customer Satisfaction74
Customer feedback is very positive, though the number of ratings is modest. Satisfaction does not establish bone-health outcomes.
Product Focus37
Calcium and vitamin D provide the clearest nutritional link to bone health when intake is low. MK-7 findings are mixed, and this serving is below the daily amount used in the positive trial.
