Product analysis
Super D-K Calcium Plus Mixed Berry Flavor can help fill mineral gaps and support normal bone maintenance. Its unidentified blend contents make the full formula harder to judge.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality46
MK-7, the folate preparation and potassium bicarbonate are favorable features of the nutrient mix. The calcium and magnesium preparations are less favorable for absorption, while several other quality details remain uncertain.
Ingredient Transparency73
Ingredient amounts and most forms are disclosed, including the vitamin D source. The unidentified blend contents and remaining unspecified forms still limit a complete comparison.
Value For Money38
Potassium contributes favorable value, but calcium, magnesium and vitamin K offer weak value for the serving cost. Value for many of the other nutrients remains uncertain.
Customer Satisfaction70
Customer feedback is positive, but only a small number of ratings supports it. That leaves more uncertainty about typical satisfaction.
Product Focus21
The minerals and vitamin D mainly help fill nutritional gaps relevant to normal bone and energy functions. Broader heart, stress and hormone benefits remain conditional, while unidentified blend contents limit a complete judgment.

Calcium and magnesium supply minerals used in bone, while vitamin D helps calcium absorption when intake or status is low. Vitamin C supports normal collagen formation, chiefly by correcting inadequate intake. The declared MK-7 contributes to bone-protein activation, although its amount is below the principal postmenopausal study exposure; potassium bicarbonate and bamboo cannot inherit evidence for different studied preparations.
How this product is rated for Bone Health
Ingredient fit65
The formula’s relevance depends on its bone-related nutrient roles and how much the declared serving supplies.
Goal fit
Bone-related nutrients sit within a broader formula, so only part of the ingredient mixture is focused on this goal.
Dose adequacy
The counted amounts provide a partial match to the comparison anchors; their nutritional contribution varies by ingredient.
Pathways76
The supplied findings describe which aspects of mineral handling, bone-protein activity and matrix support are represented.
Depth
The strongest supplied finding concerns bone mineral supply, based on the declared ingredients and amounts.
Breadth
The broader findings chiefly cover bone mineral supply, calcium absorption and regulation, with other bone-related processes less represented.
Evidence98
The counted evidence reflects the supplied ingredients and preparation matching, with clinical benefits limited by the context described above.
Evidence strength
Calcium provides the strongest counted evidence, subject to its nutritional or preparation-specific limits described for this product.
Studied preparation
Preparation matching is incomplete for Potassium, limiting transfer of preparation-specific findings.
Formulation logic100
Partner coverage and declared amounts explain the formulation findings; no configured conflict was found.
Partner coverage
The counted ingredients either stand alone in this comparison or have their relevant partner present.

Magnesium provides limited support for blood-pressure regulation; the supplied trials show small, inconsistent effects. Folate and the relevant B vitamins support homocysteine metabolism, but lowering this marker does not generally reduce major cardiac events.

Magnesium provides the strongest nutritional contribution, supporting normal energy and mineral functions when intake is low. Calcium and vitamin D also contribute to bone nutrition, while vitamin B6 and vitamin C contribute to blood-related and antioxidant functions. Several smaller nutrient amounts did not receive a separate contribution in the saved findings; that does not mean they are absent or biologically inactive.

Magnesium contributes to vascular function, although findings for arterial stiffness and blood pressure are inconsistent and more plausible with low magnesium status or elevated blood pressure. Potassium may help blood pressure when habitual intake is low; the supplied serving remains below the exposures in the cited trials. The main connection is mineral support for vascular tone, with limited support for broader cardiovascular effects.
How this product is rated for Cardiovascular Support
Ingredient fit55
The formula has a mineral contribution to vascular support alongside ingredients serving other purposes.
Goal fit
Relevant nutrients share the formula with other actives, so its focus extends beyond cardiovascular support.

Magnesium supports normal nutrition, but the small exercise-related study does not establish higher testosterone in routine, adequately nourished users.
How this product is rated for Testosterone Support
Ingredient fit50
The saved findings recognize the declared nutrients, with broader ingredients and amount differences limiting the formula’s focus.
Goal fit
The formula includes ingredients serving other purposes, reducing its focus on testosterone support.

Only one hormone route reached the coverage criterion, leaving the overall coverage narrow.
Evidence81
The strongest saved ingredient finding remains subject to the population and preparation limits of the supplied human research.
Evidence strength
Vitamin D leads the saved finding, but trials do not establish higher testosterone in adequately nourished healthy men.
Studied preparation
The saved finding recognizes the preparation, without proving a hormone response for routine use.
