Vitamin K2 is a fat-soluble vitamin belonging to the menaquinone family. Unlike vitamin K1, which is mainly involved in blood clotting, Vitamin K2 plays a critical role in calcium metabolism, cardiovascular health, bone health, and dental health. It is widely used in dietary supplements, functional foods, infant nutrition, and animal feed.
Main Applications & Benefits
1. Bone Health Support
Regulates calcium deposition in bones
Activates osteocalcin, a key protein that binds calcium to the bone matrix, improving bone mineral density and strength.
Prevents age-related bone loss
Helps reduce the risk of osteoporosis and fragile bones, especially in the elderly and postmenopausal women.
Supports healthy bone development
Used in pediatric and adolescent nutrition to promote normal skeletal growth.
2. Cardiovascular Health
Directs calcium away from blood vessels
Activates matrix Gla protein (MGP), which inhibits calcium buildup in arterial walls, helping maintain vascular elasticity and normal blood circulation.
Supports healthy arterial function
Reduces the risk of vascular calcification, one of the main factors linked to cardiovascular aging.
3. Dental Health
Supports tooth enamel and dentin formation
Promotes healthy mineralization of teeth and may help reduce the risk of cavities and periodontal issues.
Maintains healthy gum tissue
Contributes to overall oral structural health.
4. Blood Clotting & Normal Coagulation
Assists in the synthesis of coagulation factors in the liver, supporting normal blood clotting and wound healing.
Essential for maintaining hemostasis, especially in infants and individuals with fat malabsorption.
5. Antioxidant & Anti‑aging Support
Exhibits mild antioxidant properties, protecting cells from oxidative damage.
Supports healthy cellular aging and overall vitality.
6. Functional Foods & Beverages
Added to milk, yogurt, nutritional drinks, protein powders, and fortified cereals.
Commonly combined with Vitamin D3, Calcium, and Magnesium for synergistic bone and cardiovascular support.
7. Infant & Clinical Nutrition
8. Animal Feed & Aquaculture
Common Forms in Commercial Products
MK‑4 (Menatetrenone): Fast-acting, widely used in pharmaceuticals and some supplements.
MK‑7 (Menaquinone‑7): Long half-life, high bioavailability, the most popular form for dietary supplements.
Key Advantages
High bioavailability: Especially MK‑7, which remains active in the body much longer than K1.
Dual benefit: Supports both bone and cardiovascular health simultaneously.
Synergistic effect: Works strongly with Vitamin D3 and Calcium to maximize calcium utilization.
Safe profile: Well-tolerated within recommended daily intake levels.
