Super K, 2,600 mcg, 90 Softgels, Life Extension

Life Extension Super K — 2,600mcg of total Vitamin K activity per softgel in three complementary forms (K1, K2 as MK-4, and K2 as MK-7) for comprehensive bone density, arterial health, and healthy calcium balance support. Gluten-free, Non-GMO certified. 90 softgels — 3-month supply.

Why

Most people know Vitamin K helps blood clot — but its role in bone and cardiovascular health is just as important, and far less understood. Vitamin K activates proteins that direct calcium to go where it belongs (your bones) and away from where it doesn’t (your arteries). The two main forms — K1 and K2 — have distinct roles and different durations of action in the body. K2 as MK-7 is the longest-acting form, remaining active in the body for days rather than hours, making it particularly effective for supporting vascular and bone health with once-daily dosing. Life Extension Super K delivers all three forms in a single daily softgel: K1 (1,500mcg), K2 as MK-4 (1,000mcg), and K2 as MK-7 (100mcg) — 2,600mcg total Vitamin K activity (2,167% DV). Important: if you are taking warfarin or any Vitamin K antagonist, consult your healthcare practitioner before use.

Key Benefits

• Three forms of Vitamin K in one softgel — K1, K2 MK-4, and K2 MK-7
• 2,600mcg total Vitamin K activity — 2,167% DV
• Supports healthy bone density — Vitamin K activates osteocalcin for calcium incorporation into bone
• Supports heart and arterial health — activates Matrix Gla Protein (MGP) to prevent arterial calcification
• Promotes healthy calcium balance — directing calcium to bones, not arteries
• MK-7 — the longest-acting form of K2, active for days with once-daily dosing
• Vitamin C (10mg as ascorbyl palmitate) — antioxidant support
• Gluten-free | Non-GMO certified
• 90 softgels — 3-month supply at 1 softgel daily

Formula Highlights

• Vitamin K1 (Phytonadione) 1,500mcg — the plant-derived form of Vitamin K; primarily supports blood coagulation factor synthesis in the liver; also contributes to bone and arterial health; shorter half-life than K2 forms
• Vitamin K2 as MK-4 (Menaquinone-4) 1,000mcg — an animal-derived form of K2; activates osteocalcin (bone Gla protein) to incorporate calcium into bone matrix; activates Matrix Gla Protein (MGP) to inhibit arterial calcification; shorter-acting than MK-7
• Vitamin K2 as MK-7 (trans-Menaquinone-7) 100mcg — the longest-acting form of K2, with a half-life of several days; provides sustained activation of osteocalcin and MGP throughout the day; the most bioavailable and clinically studied form for bone and vascular health
• Vitamin C 10mg (as ascorbyl palmitate) — a fat-soluble form of Vitamin C; provides antioxidant protection within the lipid-based softgel matrix
