Life Extension Super K — the ultimate Vitamin K supplement with three forms of K in one daily softgel.
Why you need it
Most people know Vitamin K helps blood clot— but its role in bone and heart health is just as important, and far less understood. Vitamin K is the key that directs calcium to go where it belongs (your bones) and away from where it doesn't (your arteries). Life Extension's Super K delivers a powerful 2,600 mcg of Vitamin K activity per softgel in three complementary forms — K1, K2 as MK-4, and K2 as MK-7 — for comprehensive, all-day support of bone density, arterial health, and healthy calcium balance. Just one softgel a day.
