Life Extension Super K Vitamin K Supplement, 2000 mcg K1 + K2 (MK-4 & MK-7) — Once-Daily, 90 Softgels for Heart & Bone Support

Life Extension Super K is a once-daily multiform vitamin K softgel blend designed to support healthy arterial function and help maintain proper calcium distribution in the body.

This formula combines vitamin K1 and two bioavailable forms of vitamin K2 into one convenient softgel so adults can add targeted support for cardiovascular and bone health to their daily routine. Each softgel delivers multiple K compounds along with manufacturing standards that emphasize purity: non-GMO ingredients, gluten-free formulation, and production in the USA with quality testing.

How does Super K support heart and arterial health?

Vitamin K participates in pathways that help regulate where calcium is deposited in the body. Higher intakes of K2 have been associated with markers of cardiovascular health in population research, and providing K1 plus K2 offers complementary activity.

• Contains multiple K forms to address different biological roles.
• K2 (MK-4 and MK-7) included for sustained and tissue-specific activity.
• Supports vascular function by helping keep calcium out of arterial walls.

What specific vitamins and doses are in each softgel?

Super K supplies multiple forms of vitamin K to deliver a broad activity profile. The blend is calibrated to provide substantial K activity per serving for once-daily use.

• Provides vitamin K1 plus two vitamin K2 forms in each softgel.
• Formulation balances short-acting and longer-acting K2 variants for steady support.
• Packaged as 90 softgels for a multi-week supply at a single softgel daily dose.

How should I take these softgels for best results?

Take one softgel each day with food for improved absorption, since vitamin K is fat-soluble. Pairing the softgel with a meal containing dietary fat supports uptake of K1 and K2 into circulation.

• Take one softgel daily, ideally with a meal that contains fat.
• Consistent daily use delivers steady vitamin K activity over time.
• Consult a healthcare provider if you use anticoagulant medications.

Are there quality or ingredient assurances I should know about?

Life Extension emphasizes ingredient quality and independent testing. Products are non-GMO, gluten-free, and made in the USA from globally sourced ingredients with Certificates of Analysis available for transparency.

• Non-GMO and gluten-free formulation.
• Manufactured in the USA under quality controls and testing.
• Certificates of Analysis available for those who want batch-level details.

Who is this for: Adults seeking a comprehensive, once-daily vitamin K supplement to support cardiovascular and bone health may benefit from Super K. It’s aimed at people who want a multi-form K formula (K1 plus two K2 types) in a simple softgel, those looking for non-GMO and gluten-free options, and anyone wanting a product manufactured with quality testing.
