Vitamin K2: Bone Health Support, Vascular Calcium Regulation, Dietary Sources, and Supplementation Strategies
Vitamin K2 is an essential nutrient involved in activating proteins that regulate calcium placement in the body, directing it into bones and teeth while preventing deposits in arteries and soft tissues.
Unlike Vitamin K1, which is found in leafy greens and primarily supports blood clotting, Vitamin K2 plays a crucial role in skeletal and cardiovascular health.
Its key functions include stimulating osteocalcin to support bone mineralization and activating matrix GLA protein to prevent arterial calcification. Vitamin K2 works synergistically with Vitamin D3 and magnesium to promote strong bone structure, making it vital in osteoporosis prevention, especially in aging populations and postmenopausal women.
Dietary sources include natto (fermented soybeans), aged cheese, egg yolks, organ meats, and fermented foods. Supplements are available in MK-4 and MK-7 forms, with MK-7 offering longer activity in the body. Consistent intake supports bone density, reduces fracture risk, and may contribute to heart health.
Research explores its potential benefits in dental health, joint health, metabolic function, and immune support. Individuals taking blood-thinning medications should consult healthcare providers before supplementation due to its role in clot-related pathways.
Healthy lifestyle, nutrition planning, and regular screening support optimal bone and cardiovascular function, especially in older adults.
