Synergy
What is happening. Vitamin K2 supports directing calcium into bone and away from arteries, complementing strontium's bone-building action within a bone-health regimen.
Mechanism. Vitamin K2 activates osteocalcin (incorporating calcium into bone) and matrix Gla protein (inhibiting vascular calcification), supporting proper mineral handling while strontium stimulates osteoblasts and curbs resorption.
Recommendation. Reasonable to include vitamin K2 alongside strontium for bone support, especially when calcium and vitamin D are also used. They do not compete for absorption.
