Vitamin K2 Interactions

Dietary vitamin K1 from greens complements K2 supplementation for bone and cardiovascular health.

Vitamin K2 activates osteocalcin and matrix Gla protein, which bind calcium and direct it into the bone matrix while keeping it out of arterial walls. Calcium supplementation paired with adequate K2 supports bone density and reduces the risk of misplaced calcium in soft tissue.

Vitamin D3 increases calcium absorption and stimulates production of vitamin K-dependent proteins (osteocalcin, matrix Gla protein) that themselves require K2 for activation. Co-supplementation supports bone density and may reduce vascular calcification compared with D3 alone.

Vitamin K2 helps direct calcium (mobilized by vitamin D) into bones, not arteries
