Analysis

Microcrystalline hydroxyapatite supplies calcium, while D3 and MK-7 support absorption and bone-protein function. Magnesium, zinc, copper, manganese, potassium, boron, and vitamin C broaden the mineral network.

All active quantities are visible, and the formula avoids proprietary blends. Magnesium oxide is less appealing than better-absorbed alternatives, and boron remains a supporting amount.

It suits adults who want a fuller bone formula without an extreme calcium serving. The two-capsule format is manageable, though animal-derived hydroxyapatite and K2 narrow suitability for some users.

Who is it for
  • Adults seeking multi-nutrient bone support
  • People wanting moderate calcium with D3 and K2
Best for
  • Broad daily bone-health support
  • Calcium with mineral and vitamin cofactors

Pros

  • Hydroxyapatite calcium
  • Includes D3 and MK-7
  • Broad mineral cofactors
  • Transparent quantities
  • Strong serving value

Cons

  • Magnesium oxide form
  • Low boron amount
  • Two-capsule serving
  • Animal-derived calcium source

Warnings

  • Keep vitamin K2 intake consistent with warfarin.
  • Separate calcium from thyroid hormone, iron, bisphosphonates, and certain antibiotics.
  • Hydroxyapatite is animal-derived and will not suit vegetarian or vegan users.

Nutrient quality

86 Highest impact

Hydroxyapatite, vitamin D3, and vitamin K2 are favorable, while magnesium oxide is a weak form. Calcium is practical and cofactors add breadth, but boron and several trace minerals are modest.

Report overview
Calcium (Microcrystalline Hydroxyapatite) · 333.3 mg OverallScore90
A+ Active Ingredient Quality & BioavailabilityB- Dose, Safety & Label TransparencyA+ Value

A premium hydroxyapatite source provides a useful and clearly disclosed calcium amount. Its serving is efficiently sized and accompanied by K2 and bone-supporting minerals. Low serving cost makes the focused formula an excellent value.

View ingredientView products
Boron (Boron Citrate) · 1 mg OverallScore52
C Active Ingredient Quality & BioavailabilityD+ Dose, Safety & Label TransparencyF Value

Boron citrate offers a suitable organic source, but only 1 mg is delivered per serving. Compound and amount are stated clearly enough for routine label use, while premium source verification is absent. The low dose makes the normalized boron value expensive despite a modest serving cost.

Ultra BoneUp

Jarrow Formulas
<p>Calcium, vitamin D3, magnesium, MK-7, silicon, boron, and cartilage collagen cover more bone pathways than the original formula. Magnesium oxide and modest secondary amounts remain limitations, but silicon, collagen, and broader cofactor coverage add useful depth.</p>

Calcium Hydroxyapatite Caps

NOW
<p>Hydroxyapatite supplies calcium with naturally paired phosphorus in a simple, clearly dosed capsule. It omits vitamin D, vitamin K2, magnesium, and boron, but the focused calcium form is stronger and easier to assess than a formula partly reliant on magnesium oxide.</p>
90 Performance

Cal/Mag 500 mg/250 mg

NaturesPlus
<p>Chelated calcium and magnesium provide balanced core minerals with stronger form quality than the original product’s magnesium oxide. Vitamin D, vitamin K2, and boron are absent, but the simple formula offers a clear foundation for users who obtain those cofactors elsewhere.</p>

Calcium Citrate +D3 Petites

21st Century
<p>Calcium citrate and vitamin D3 provide a focused bone-support base at a lower serving cost. Magnesium, vitamin K2, and boron are missing, but the clearly identified calcium form is more refined than the original product’s magnesium oxide component.</p>
84 Budget

Citracal Petites Calcium Citrate +D3

Bayer Citracal
<p>A moderate calcium amount with vitamin D3 comes in a long-supply format at a lower serving cost. The supplied details do not confirm the calcium form named in the title, and magnesium, vitamin K2, and boron are absent.</p>
82 Budget

Calcium Citrate 600 mg

Spring Valley
<p>A meaningful calcium amount and long supply provide a much lower-cost bone-mineral option. The supplied ingredient details do not verify the citrate form, and the focused product lacks the original formula’s vitamin D, vitamin K2, magnesium, and trace minerals.</p>
91 Value

Calcium Citrate Pure Powder

NOW
<p>A substantial calcium citrate amount provides a well-absorbed, simple option at a lower serving cost. It lacks vitamin D, vitamin K2, magnesium, and boron, but the focused powder offers strong form quality and avoids paying for weaker secondary forms.</p>
85 Value

600+D3

21st Century
<p>Calcium and vitamin D3 provide a direct bone-maintenance pairing at a very low serving cost. Carbonate is less flexible than citrate and the formula omits magnesium, vitamin K2, and boron, but the economical, focused design delivers good basic value.</p>
88 Value

Boron 5mg

Best Naturals
<p>Boron citrate provides a defined organic form at a meaningful maintenance amount and very low serving cost. It does not replace the original calcium, magnesium, vitamin D, or vitamin K2, but it addresses the original product’s lightly dosed boron more effectively.</p>
