Product analysis
Organic Plant Calcium supplies calcium and vitamin D that support normal bone nutrition when dietary intake is low. Its unnamed blend contents make the added ingredients difficult to assess.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality41
Vitamin K is supplied in the favorable MK-7 form. Algae identifies the mineral source without resolving calcium's exact form, and other quality details remain limited.
Ingredient Transparency76
Serving amounts and most ingredient forms or sources are disclosed. The unnamed blend contents leave part of the formula unclear.
Value For Money31
The calcium and vitamin K comparisons indicate limited value for the serving. Other contributions lack enough information for a dependable price comparison.
Customer Satisfaction89
Customer feedback is very positive across a large number of ratings. The broad review base supports confidence in the satisfaction picture, without proving bone-health benefits.
Product Focus39
The formula's main ingredients have clear nutritional roles in bone mineral supply and calcium handling. Undisclosed blend contents limit confidence in the full mix, and these nutrient roles do not establish fracture protection.
