Product analysis

59 out of 100

Bone Boost may help fill calcium and magnesium gaps that matter for normal bone health. Some mineral forms are favorable, although unclear proportions and silicon details make ingredient quality uneven.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality59

Magnesium, copper, boron and vitamin K use favorable forms, but quality is uneven across the formula. Unknown calcium proportions and an unclear silicon form limit confident comparison of those ingredients.

Ingredient Transparency75

All ingredient amounts and most forms are listed, making the main nutrients easy to identify. Missing proportions for the calcium and vitamin D sources leave part of the formula unclear.

Value For Money45

The available comparisons suggest moderate value for the main minerals, with boron less competitive. Value for several other ingredients remains uncertain.

Customer Satisfaction84

Customers generally rate the formula positively across a substantial review base. Their satisfaction does not establish stronger bones or other health outcomes.

Product Focus33

Bone nutrition is the clearest purpose, with calcium and magnesium helping fill dietary gaps. The small vitamin D contribution and a milk-protein amount below the studied amount limit parts of the formula, while its wider health benefits are less certain.

Calcium and magnesium can help fill dietary gaps needed for normal bone mineralization and metabolism. MK-7 adds a limited bone-protein-related contribution, while milk basic protein has small-trial findings for bone density and turnover markers. Its 20 mg serving is below the 40 mg daily amount studied. Silicon's amount is unresolved, and the small vitamin D amount limits this formula's contribution to calcium regulation.

How this product is rated for Bone Health

Ingredient fit63

Several bone-related ingredients are present, but small amounts and unresolved silicon limit their contribution.
Goal fit
Several bone-related ingredients are present, but small amounts and unresolved silicon limit their contribution.
Dose adequacy
Calcium, magnesium, MK-7 and milk basic protein contribute partially; silicon is unresolved and several smaller nutrient amounts are excluded.

Pathways50

Calcium absorption and regulation receives the strongest saved finding. These functional areas do not establish clinical bone outcomes.
Depth
Calcium absorption and regulation is the strongest represented area in the saved finding.
Breadth
Calcium regulation alone meets the criterion; mineral supply, protein activation, matrix formation and remodeling do not.

Evidence100

Calcium leads the saved evidence finding. The supporting evidence has nutritional, preparation or population limits and does not establish fracture prevention.
Evidence strength
Calcium supplies the leading saved evidence contribution; this is not a measure of clinical benefit.
Studied preparation
The retained ingredients receive preparation recognition in the saved finding, without establishing superiority or equivalent clinical outcomes across forms.

Formulation logic92

Calcium's partner requirement is not fully met, reducing that part of the finding; no evaluated conflict was identified.
Partner coverage
Calcium's partner requirement is not fully met in the saved finding.
Conflicts
No evaluated ingredient conflict was identified.
Effective doses
Five included ingredients meet the minimum amount criterion; silicon does not because its amount is unresolved.

Calcium and magnesium provide the main contribution to bone and mineral nutrition, at 300 mg and 125 mg per serving. Vitamins D and K also relate to mineral physiology, though their smaller amounts contribute little in the saved findings. Benefit depends on whether the supplement fills a dietary gap.

Magnesium at 125 mg and vitamin C at 90 mg help meet nutritional needs related to normal energy metabolism and tiredness. Their contribution is most meaningful when intake is inadequate, rather than as an immediate energy boost.
