Thorne Vitamin D + K2 Liquid - Bone & Immune Support in Convenient Drops

Superior Bone Health & Calcium Metabolism: Vitamin D3 enhances calcium absorption in the intestinal tract, while vitamin K2 (MK-4) activates osteocalcin, the protein matrix that binds calcium into bone tissue. This synergistic combination ensures calcium reaches your bones rather than accumulating in soft tissues, supporting healthy bone density and reducing fracture risk throughout all life stages, particularly important for postmenopausal women and aging adults.

Cardiovascular Protection & Arterial Health: Vitamin K2 activates matrix Gla-protein (MGP), which inhibits calcium deposition in arterial walls and soft tissues. By directing calcium away from blood vessels and toward bones, this formula helps maintain arterial elasticity and supports healthy cardiovascular function. The MK-4 form of vitamin K2 has been clinically studied for its powerful influence on vascular health, working synergistically with vitamin D3 to provide comprehensive cardiovascular support.

Enhanced Immune System Function: Vitamin D3 plays a crucial role in modulating both innate and adaptive immune responses, supporting the production of antimicrobial peptides and regulating inflammatory pathways. Maintaining optimal vitamin D levels throughout the year helps support your body's natural defense mechanisms, promotes healthy immune cell function, and contributes to overall immune system resilience during seasonal challenges and periods of increased stress.

Premium Liquid Delivery & Bioavailability: Formulated in medium chain triglyceride (MCT) oil and preserved with natural mixed tocopherols (vitamin E), this liquid formula offers superior absorption compared to tablets or capsules. The metered-dispenser bottle ensures accurate, individualized dosing without measuring, while the liquid format can be easily added to food or beverages. The MK-4 form of vitamin K2 used is the most extensively researched menaquinone, providing confidence in efficacy and clinical validation.
