Liquid Vitamin K2 – Thorne | Liquid MK‑4 for Strong Bones, Vascular Health & Normal Coagulation
Liquid Vitamin K2 contains vitamin K2 in a base of medium-chain triglycerides from palm kernel oil and mixed tocopherols. The liquid form allows for easy dosing. Vitamin K can contribute to the maintenance of normal bones and normal blood coagulation.
Vitamin K2 plays a crucial role in maintaining bone and cardiovascular health. Essential for activating proteins that regulate the body's calcification, K2 helps direct calcium to the bones and teeth, where it is needed, and prevents it from depositing in arteries and other soft tissues, thus preventing arteriosclerosis. In addition to strengthening bone density and reducing the risk of fractures, vitamin K2 promotes arterial flexibility and improves cardiovascular function. Incorporating foods rich in vitamin K2, such as fermented cheeses, natto, and egg yolk, or considering supplementation, can be beneficial for overall health.
Menatetrenone (MK-4) is the most studied form of vitamin K2 in a scientific context. It belongs to the group of menaquinones and acts distinctly from vitamin K1 (phylloquinone), with recognized relevance for bone health. Vitamin K has a functional role in activating vitamin K-dependent proteins involved in bone mineralization and blood coagulation — functions supported by authorized claims under Regulation (EC) No 432/2012.
The product is formulated in medium-chain triglyceride oil, a stable lipid base, and preserved with natural mixed tocopherols, without synthetic preservatives. Each 30 ml bottle contains approximately 1200 individual drops (about 80 doses of 15 drops). The standard dose of 15 mg is far above the EU NRV of 75 µg — this is a targeted use dose, to be used as directed by a healthcare professional.
