K2Quest® MK-7
LAST UPDATED JULY 05, 2026
K2Quest® is a branded, stabilized form of vitamin K2 as menaquinone-7 (MK-7) — the longest-acting, best-studied form of vitamin K2.
Why MK-7
Vitamin K2 activates the proteins that direct calcium into bones and away from arteries. The MK-7 form stays active in the body far longer than MK-4 or K1, making once-daily dosing meaningful.*
Why it's paired with D3
Vitamin D3 increases calcium absorption; K2 tells that calcium where to go. Supplementing them together is the logic behind our combined formula.*
