Vitamin K

Thorne’s Vitamin K supplement stands out by including MK-4 and MK-7 MenaQ7®, two highly effective forms of vitamin K2. MK-4 (menaquinone-4) plays a crucial role in activating osteocalcin, a protein needed to bind calcium to the bone matrix, thereby promoting strong and healthy bones. It also supports blood clotting by activating proteins that prevent excessive bleeding. Thorne’s supplement offers a higher concentration of MK-4 than most other products, providing enhanced support for these vital functions. MK-7 (menaquinone-7) is known for its superior bioavailability and is the longest-lasting, most bioactive form of Vitamin K, with MenaQ7® being the only clinically validated, patented version of MK-7 that remains in the bloodstream for up to 72 hours. This combination ensures comprehensive support for healthy bones, arteries, and overall wellbeing, making Thorne’s Vitamin K a standout choice in vitamin K supplementation.

Thorne sets the standard for excellence in the supplement industry. Recommended by over 100 professional sports teams and U.S. National Teams, Thorne offers a curated bundle of clean, science-backed supplements and treats designed to fuel your body naturally and effectively.
