Vitamin K2 (MK-7), 45 mcg, Life Extension is a dietary supplement designed to support the correct utilization of calcium in the body, thereby supporting the health of bones, teeth and blood vessels. The product contains vitamin K2 in the form of trans menaquinone-7 (MK-7), 45 mcg per serving, which represents 38% of the reference nutritional value. The MK-7 form is recognized for its high bioavailability and prolonged half-life in the body, enabling sustained action on K-dependent proteins involved in calcium metabolism.
Calcium is essential for bone and dental structure, but amount alone is not enough — equally important is where the calcium is deposited. Vitamin K2 plays a role in activating key proteins (such as osteocalcin and Matrix Gla Protein – MGP) that direct calcium to where it is needed (in bones and teeth) and prevent excessive deposition in soft tissues or blood vessel walls. Thus, K2 acts as a "guide" for calcium, complementing the effects of vitamin D and mineral intake.
As we age, the risk of bone demineralization increases, joints and the spine are more stressed, and maintaining vascular elasticity becomes increasingly important. In addition, modern diets are often low in natural sources of vitamin K2 (traditional fermented foods, certain aged cheeses), making supplementation a useful option for many people. Vitamin K2 (MK-7), 45 mcg, Life Extension offers a balanced dose that is easy to integrate into a daily routine to support the osteo-articular and cardiovascular systems.
Vitamin K2 (MK-7) is essential for activating osteocalcin, a protein produced by osteoblasts (bone-forming cells) that binds calcium to the bone matrix. Without sufficient vitamin K2, osteocalcin remains inactive and cannot effectively fix calcium in bone. Supplementation with K2 supports osteocalcin activation, promotes incorporation of calcium into bone structure, and helps maintain strong, well-mineralized teeth.
Calcium is beneficial in bones but can be problematic when it accumulates in blood vessel walls or other soft tissues. Here Matrix Gla Protein (MGP), another K-dependent protein, helps control calcium deposits in soft tissues. Vitamin K2 (MK-7) supports MGP activation, helps maintain vascular flexibility, and promotes a healthier distribution of calcium in the body.
Over time, bone mineral density is influenced by calcium intake, vitamin D, vitamin K2 and hormonal balance. K2 (MK-7) works together with these factors by supporting bone remodeling processes (formation vs. resorption), contributing to efficient mineralization of the bone matrix and supporting resistance to mechanical stress and daily microtrauma.
Bones, joints and intervertebral discs work together to support body weight and mobility. A well-mineralized bone provides a more stable support for joints and the spine. By promoting calcium deposition in bone, vitamin K2 indirectly contributes to structural stability of the spine and load-bearing bones, supports correct posture and reduces long-term impact of repetitive mechanical stress.
The need for vitamin K2 is relevant across life stages, not just for the elderly. In children and adolescents it can be important during growth when bone mass is formed; in adults to maintain bone mass and resistance to stress; and in older adults to slow density loss and maintain mobility.
Calcium metabolism concerns not only bones but also muscle and nerve function. Calcium is essential for muscle contraction and relaxation, nerve impulse transmission and blood coagulation. Vitamin K2 helps ensure correct use of calcium, supporting a better balance between bone mineralization and muscular functions.
Through all these effects – activation of osteocalcin and MGP, directing calcium to bones and teeth, protecting blood vessels, supporting bone density and skeletal structure – Vitamin K2 (MK-7), 45 mcg, Life Extension is positioned as an essential supplement for those who want to care for their osteo-articular and cardiovascular systems intelligently, by optimizing calcium metabolism in the body.
