Vitamin K2 Liquid: A High-Potency MK-4 for Bone and Heart Health

Thorne’s Vitamin K2 Liquid offers a high-potency, easy-to-use form of vitamin K2 as MK-4 (menatetrenone). This essential nutrient is a crucial director for calcium in the body, helping to ensure it is deposited in the bones and not in the arteries and other soft tissues. The convenient liquid dropper format provides a potent 1 mg of K2 per drop, allowing for flexible dosing. It’s a foundational supplement for individuals seeking to support both bone density and cardiovascular wellness.*

How It Works: The “Calcium Director” Vitamin

Vitamin K2’s primary role is to activate specific proteins that are essential for bone and cardiovascular health.

Building Stronger Bones
This formula features the MK-4 form of vitamin K2. It is the most well-researched form of K2 for supporting bone health. K2 activates osteocalcin, a protein that acts like a structural glue, binding calcium into the bone matrix. Therefore, a sufficient amount of K2 is essential for building and maintaining strong, healthy bones.*

Promoting Flexible Arteries
In addition to its role in bone health, vitamin K2 also activates matrix Gla protein (MGP). MGP is a powerful inhibitor of soft tissue calcification. By activating MGP, K2 helps to keep calcium out of the arteries, which promotes blood vessel elasticity and supports overall cardiovascular health. The formula is preserved with mixed tocopherols and suspended in a base of medium-chain triglyceride oil for enhanced absorption.*
