Calcium Magnesium plus Boron can help fill calcium and magnesium gaps that matter for normal bone and muscle function. The mineral blends do not disclose their proportions, so their listed forms give an incomplete picture of likely absorption.

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

Nutrient Quality41

Calcium and magnesium combine forms with different absorption potential, but the proportions are undisclosed. The presence of citrate therefore does not show how well either whole blend will be absorbed.

Ingredient Transparency80

The mineral amounts and forms are stated, helping you compare the serving with other sources. The shares of the calcium and magnesium forms are omitted, so their individual contributions remain unclear.

Value For Money65

Calcium provides good value at the serving cost, while boron is moderately priced. Magnesium offers a less clear value advantage because the blend includes oxide without disclosing its share.

Customer Satisfaction84

Customer feedback is favorable across 1,130 ratings. The substantial review base gives useful satisfaction context without proving health benefits.

Product Focus70

The clearest purpose is filling mineral gaps relevant to normal bone, muscle and energy function. Broader stress, hormone and cardiovascular effects are more uncertain and depend on individual circumstances.

Magnesium · 400 mgBoron · 3 mg

Magnesium contributes to normal energy and mineral functions, while calcium helps fill a dietary gap relevant to maintaining bones. The calcium contribution is most useful when intake is inadequate. Boron has limited, context-specific evidence on mineral metabolism, which does not establish broad health benefits for routine use.

Magnesium · 400 mgCalcium · 1000 mgBoron · 3 mg

Calcium supplies material for normal bone mineralization, while magnesium contributes to normal bone metabolism. The 1,000 mg calcium and 400 mg magnesium per serving can make substantial contributions when dietary intake is low; total daily needs include food as well as supplements. Boron's role in mineral metabolism does not establish an additional bone-density benefit. Vitamin D is absent, limiting the formula's paired calcium-and-vitamin-D coverage.

How this product is rated for Bone Health

Ingredient fit91

The formula contains several bone-related nutrients with clearly declared amounts.
Goal fit
The included nutrients relate to bone support, though the product is associated with broader goals.
Dose adequacy
The declared calcium and magnesium amounts provide substantial mineral intake; larger servings do not establish extra bone benefit.

Pathways80

Mineral supply is the strongest aspect, alongside calcium regulation.
Depth
Bone mineral supply is the strongest represented aspect.
Breadth
Mineral supply and calcium regulation are represented; bone-protein activation and matrix formation receive little or no contribution.

Evidence100

Calcium supplies the strongest supporting evidence for nutritional gap-filling; fracture outcomes remain mixed.
Evidence strength
Calcium provides the strongest evidence, supporting intake adequacy with mixed fracture-trial findings.
Studied preparation
The included preparations are accepted in the supplied findings; this does not establish superior bone outcomes for particular mineral salts.

Formulation logic94

Calcium lacks its expected vitamin D companion, though the included amounts meet the minimum criterion. No assessed conflict was found.
Partner coverage
Vitamin D is absent, so calcium lacks its expected companion.
Conflicts
No assessed ingredient conflict was found.
Effective doses
All included contributors meet the minimum amount criterion; that does not establish a clinically effective dose for every nutrient.
