D3 gets calcium in the door. K2 tells it where to go. Without K2, absorbed calcium can deposit in arteries instead of bones. All three are required for the full bone-protection pathway.
This stack requires two products. The D3 + K2 combo covers two of the three; calcium is taken separately.
D3 + K2 (MK-7) in one softgel. D3 increases gut calcium absorption while K2 activates osteocalcin and Matrix Gla Protein to direct calcium into bone and prevent arterial calcification. Both are fat-soluble.

Coming soonHow to take this stack: Split calcium (500-1,000 mg) into two doses with meals. Take D3 (2,000-4,000 IU) + K2 (90-200 mcg MK-7) together with your fattiest meal. All three with food containing fat. Never take calcium and iron within 2 hours of each other. K2 can interact with warfarin and blood thinners; consult your doctor. This is a long-term bone health strategy; consistency over months matters more than any single dose.
