AI assessment of the formula, label and price. How scoring works
Nutrient Quality50
Iodine has a favorable identified source, while vitamin D form quality cannot be compared confidently. Vitamin K lacks a clearly disclosed form, limiting a judgment from the label.
Ingredient Transparency88
All nutrient amounts are disclosed, so serving quantities can be compared. Vitamin D and iodine forms are named, while vitamin K is not clearly specified.
Value For Money67
Vitamin K offers favorable value, and iodine is also reasonably priced within the serving. Vitamin D cannot be compared reliably, leaving part of the price assessment uncertain.
Customer Satisfaction94
Customer ratings are very positive across a large review base. The volume gives a broad picture of satisfaction without establishing individual health effects.
Product Focus72
The short formula centers on bone nutrition, with iodine also relevant to low dietary intake. The large vitamin D serving does not establish stronger benefits or broader suitability.
