Advanced Calcium Complex combines minerals and vitamins that can help fill dietary gaps relevant to bone maintenance. The proportions of its calcium and magnesium sources are not disclosed, making the blends harder to compare.

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

Nutrient Quality59

Copper and vitamin K have clearly identified forms, while calcium and magnesium mix several sources. Unknown blend proportions limit a precise judgment of the main minerals’ quality.

Ingredient Transparency77

All ingredient amounts and most forms are listed. Missing calcium and magnesium blend proportions leave their individual source contributions unclear.

Value For Money42

Value varies across the formula, with vitamin K offering better value than magnesium or boron. Calcium, copper and manganese fall in the middle, while some other ingredients remain uncertain.

Customer Satisfaction90

Customer ratings are very positive. Thousands of ratings give a substantial picture of customer satisfaction.

Product Focus63

Bone maintenance is the clearest purpose, especially when mineral intake is low. Wider claims for hormones, calm and energy have more limited or conditional support.

Calcium supplies material for bone mineralization, vitamin D supports calcium absorption, and magnesium contributes to normal bone metabolism, particularly when intake is inadequate. The 1,000 mg calcium serving is a substantial mineral contribution, rather than a universal supplemental target. MK-7 supports bone-protein activation, but its 65 mcg serving is below the exposure used in the favorable postmenopausal trial, and fracture prevention is not established. Copper also supports collagen cross-linking when intake is low.

How this product is rated for Bone Health

Ingredient fit78

Calcium, vitamin D and magnesium give the formula a clear mineral focus; MK-7 and copper add narrower roles.
Goal fit
The relevant ingredients are focused on bone mineral supply and its supporting functions.
Dose adequacy
Calcium and magnesium make substantial contributions; the smaller MK-7 and copper servings provide more limited coverage.

Pathways80

Mineral supply and calcium regulation dominate; bone-protein and collagen contributions are smaller.
Depth
Calcium and magnesium make mineral supply the strongest represented route.
Breadth
Mineral supply and calcium regulation are substantially represented; bone-protein activation and collagen-matrix functions are less covered.

Evidence100

Calcium provides the strongest nutritional foundation, while MK-7 findings remain preparation- and population-specific.
Evidence strength
Calcium anchors the evidence for nutritional intake-gap support; this does not establish fracture prevention for every user.
Studied preparation
The included preparations match those recognized in the supplied findings, including explicitly identified MK-7.

Formulation logic100

The included ingredients have their required partners and no configured conflict.
Partner coverage
Calcium and vitamin D are both present at amounts that satisfy the supplied pairing.
Conflicts
No configured conflict was identified, and vitamin D does not trigger the high-amount condition.
Effective doses
All included ingredients meet the inclusion threshold; the smaller zinc serving is excluded.

Calcium helps fill a dietary gap relevant to bone maintenance, while magnesium, vitamin D and vitamin K contribute additional mineral-related nutrition. Magnesium also contributes to energy-related processes. Their mixed forms and the presence of D with K do not establish superior effects or an added combination benefit. Amount coverage is uneven, and the small zinc amount is excluded from the saved contribution; adequate nutrition does not imply further benefit from supplementation.

How this product is rated for Everyday Health

Ingredient fit75

Several minerals and vitamins contribute with partial overall amount coverage; low zinc is excluded.
Goal fit
The counted nutrients give the formula a focused nutritional purpose, alongside links to other goals.
Dose adequacy
Calcium and magnesium reach full saved amount coverage; D, K and boron receive partial coverage.

Pathways80

Magnesium, D and K cover energy-related processes and mineral metabolism.
Depth
Energy-related processes and mineral metabolism both reach full coverage.
Breadth
Two categories meet the coverage threshold: energy-related processes and mineral metabolism.

Evidence86

Magnesium leads the evidence finding, with conditional usefulness for dietary gaps.
Evidence strength
Magnesium supplies the leading evidence contribution without establishing additional benefit above adequate nutrition.
Studied preparation
All counted declarations receive full preparation recognition; mixed minerals and MK-7 receive no automatic superiority.

Formulation logic100

Partner checks are satisfied and no configured conflict was found.
Partner coverage
No counted ingredient lacks a required partner; this does not establish D/K or mineral synergy.

Vitamin K · 65 mcgMagnesium · 500 mgVitamin D · 25 mcg

Magnesium provides limited support for blood pressure and vascular tone, with small and inconsistent effects in the supplied evidence. The identified MK-7 preparation has limited arterial-stiffness evidence from selected populations and longer daily use, while its 65 mcg serving is below the cited 180 mcg/day exposure. Vitamin D does not establish routine cardiovascular prevention, and no added benefit from combining vitamins D and K is supported.

Magnesium · 500 mgZinc · 5 mgVitamin D · 25 mcgBoron · 2 mg

Zinc helps maintain normal testosterone when zinc intake is low; replenishing a deficiency can restore levels, but extra zinc has not shown the same benefit when intake is adequate. Magnesium supplies an essential mineral, but its testosterone findings come from a small exercise-related study. The supplied information does not establish a routine increase in testosterone or free testosterone from these forms and amounts. Boron has inconsistent short-term hormone findings rather than established lasting benefit.

How this product is rated for Testosterone Support

Ingredient fit60

The ingredients and declared amounts provide a nutritional connection to this goal, with the limits described below.
Goal fit
The formula includes goal-related nutrients alongside ingredients aimed at other nutritional needs.
Dose adequacy
Some present nutrients do not enter the amount comparison; the counted ingredients have varying amounts relative to its reference ranges.

Pathways70

The saved findings cover specific hormone pathways, with limited transfer from the supplied human evidence.
Depth
The saved finding centers on free-testosterone availability; magnesium evidence remains tied to specific exercise conditions.
Breadth
Only one tracked hormone pathway reaches the coverage threshold; the other aspects remain uncovered.

Evidence81

The strongest included evidence and preparation matches have different meanings: a match alone does not establish routine hormone benefit.
Evidence strength
Vitamin D leads the included evidence, with benefits dependent on population and initial nutrient status.
Studied preparation
The counted preparations receive a study match in the saved findings, without proving that every listed form independently raises testosterone.

Formulation logic100

The counted ingredients meet the saved companion and amount checks; the configured zinc concern is considered separately.
Partner coverage
No required companion is missing for the counted ingredients; this does not imply an added benefit from combining them.
Conflicts
Copper is present, so the high-zinc-without-copper concern does not apply.
Effective doses
All counted ingredients clear the saved minimum amount threshold, which is a comparison cutoff rather than a proven effective testosterone dose.

Magnesium has limited, inconsistent support for blood-vessel function and arterial stiffness. This product also identifies vitamin K as MK-7, which has limited arterial-stiffness evidence in postmenopausal women; its 65 mcg serving is below the studied 180 mcg daily exposure. Vitamin D does not establish added cardiovascular protection or a D3/K2 combination benefit.

How this product is rated for Cardiovascular Support

Ingredient fit56

Magnesium is a key ingredient in the saved cardiovascular-related findings. Support from the disclosed amounts is uneven.
Goal fit
The cardiovascular-related ingredients sit within a broader formula that includes ingredients serving other purposes.

The strongest saved coverage concerns blood-vessel tone and mineral balance; this does not establish a clinical outcome.
Breadth
The routes meeting the breadth criterion are blood-vessel tone and mineral balance. Other routes receive less or no coverage.
