Analysis

Calcium hydroxyapatite provides the mineral base, while D3 and MK-7 support calcium use and bone-protein activation. Magnesium, zinc, copper, manganese, boron, and vitamin C add a broad cofactor network in one capsule.

The design is more complete than calcium-only products, and all active amounts are individually disclosed. Magnesium oxide is a weaker choice than more absorbable forms, while boron and several trace minerals are modest.

It fits adults who want convenient broad bone support rather than a large calcium dose. The hydroxyapatite is animal-derived, and the vitamin K2 requires attention for people using warfarin.

Who is it for
  • Adults seeking broad one-capsule bone support
  • People who prefer moderate calcium with multiple cofactors
Best for
  • Convenient daily bone support
  • Combining hydroxyapatite with D3 and K2

Pros

  • One-capsule serving
  • Includes D3 and MK-7
  • Broad trace-mineral cofactors
  • Clearly stated amounts
  • Strong practical value

Cons

  • Magnesium is mainly oxide
  • Boron amount is modest
  • Calcium is a partial rather than full contribution
  • Animal-derived hydroxyapatite

Warnings

  • Vitamin K2 intake should remain consistent for people using warfarin.
  • Calcium can reduce absorption of thyroid hormone, iron, bisphosphonates, and certain antibiotics.
  • The hydroxyapatite source is animal-derived and will not suit vegetarian or vegan users.

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

Premium microcrystalline hydroxyapatite supplies a clearly disclosed calcium amount. The dose stays below the absorption ceiling, while K2 and other bone cofactors broaden the formula. Efficient serving cost creates excellent value for a specialized bone product.

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

Boron citrate is a suitable organic form, but the serving supplies only 1 mg. The label is reasonably clear while offering no trademarked or independently verified source. A low serving price still becomes expensive when normalized to a useful boron amount.

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>
87 Budget

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>
