THORNE Vitamin K2 (as MK-4) Liquid Drops - Concentrated Drops for Bone, Heart & Blood Vessel Health

Description
Additional Information

Why Your Body Needs Vitamin K2 MK-4

Calcium is essential, but where it ends up matters. Without enough vitamin K2, calcium can accumulate in arteries rather than bones. THORNE's liquid MK-4 (menatetrenone) provides a rapid-acting form of K2 to support proper calcium metabolism. This concentrated formula allows flexible dosing, making it easy to meet your individual needs for bone and cardiovascular health.

Key Benefits of Vitamin K2 MK-4

Bone Health: Helps activate osteocalcin, which binds calcium to bone matrix, contributing to bone density and strength.
Heart Health: Supports arterial flexibility and normal blood vessel function by reducing calcium buildup in vessel walls.
Calcium Metabolism: Works with vitamin D to ensure calcium is deposited in bones and teeth rather than soft tissues.

These benefits are supported by decades of research on MK-4.

What Makes THORNE Vitamin K2 Different?

THORNE uses MK-4 (menatetrenone), the most studied form for bone and heart health. Unlike MK-7 with a longer half-life, MK-4 is quickly used by the body, ideal for consistent support. Each drop supplies 1 mg of MK-4, and the liquid form allows easy dose adjustment. Every batch is tested four times—from raw material through final product—ensuring purity and potency.

Why Choose THORNE for Your Supplement Routine?

THORNE is the #1 most recommended supplement brand by healthcare professionals (2026 independent survey). Used by over 100 professional sports teams, their products are trusted for purity. This liquid vitamin K2 is gluten-free, dairy-free, and soy-free, and third-party tested. Rigorous in-house testing guarantees high quality.

How to Use THORNE Vitamin K2 Liquid

The self-dispensing top delivers a precise drop per press. Place drops under the tongue or mix into a beverage. For best absorption, take with a meal containing fat as vitamin K2 is fat-soluble. Typical dosages range from 1 to 10 mg daily; follow the advice of your healthcare professional. The liquid form is perfect for those who dislike pills or need flexible dosing.

Who Should Consider Vitamin K2 Supplementation?

Anyone wanting to support bone and heart health as they age can benefit. Those with limited dietary K2 (from natto, cheese, egg yolks) may especially need supplementation. It is often paired with vitamin D. If you take blood-thinning medications like warfarin, consult your healthcare practitioner before use, as vitamin K2 can interfere with their action.

What to Look for in a Vitamin K2 Supplement

Consider the form: MK-4 for rapid action or MK-7 for longer effects. Purity and third-party testing are essential to avoid contaminants. Liquid supplements provide dose flexibility and easy absorption, especially for sensitive digestive systems. THORNE's liquid MK-4 meets these criteria with a concentrated, high-quality formula.
