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.

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.

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.

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.

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.

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.

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.

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.

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.
