Calcium and Vitamin K2 are generally complementary — many people take them together. Always combine calcium supplementation with vitamin K2 (MK-7 form, 90–180 mcg/day) to optimize bone deposition and reduce arterial calcification risk, particularly in individuals on long-term calcium therapy.
Co-supplementation directs calcium into bone while reducing vascular calcification risk. Studies show MK-7 supplementation alongside calcium+D3 improves bone mineral density and carboxylated osteocalcin levels compared to calcium+D3 alone.
Vitamin K2 (MK-7) carboxylates osteocalcin, enabling it to bind calcium ions within the bone matrix (hydroxyapatite). K2 also activates matrix Gla protein (MGP), which prevents calcium deposition in arterial walls. Without K2, supplemental calcium may accumulate in soft tissues rather than bone.
What to do: Always combine calcium supplementation with vitamin K2 (MK-7 form, 90–180 mcg/day) to optimize bone deposition and reduce arterial calcification risk, particularly in individuals on long-term calcium therapy.
