MK-7 (Vitamin K2) 150 mcg 100 caps
Vitamin K refers to a family of similar compounds that play a role in blood coagulation and bone health.*  Vitamin K2 (menaquinone) is particularly important for bone mineralization and calcium metabolism.*  Menaquinones work together with vitamin D to direct calcium deposits to bones instead of soft tissues, which is important for both skeletal and cardiovascular health.*  Research shows that menaquinone-7 (MK-7) is more bioavailable and has a longer half-life than other forms of vitamin K.*  MK-7 is formulated with all-natural menaquinone-7, which is derived from fermented soy.Menaquinone-7 (MK7), which is abundant in fermented soybeans (natto), has been demonstrated to stimulate osteoblastic bone formation and to inhibit osteoclastic bone resorption.[100] In another study, use of MK-7 caused significant elevations of serum Y-carboxylated osteocalcin concentration, a biomarker of bone formation. MK-7 also completely inhibited a decrease in the calcium content of bone tissue by inhibiting the bone-resorbing factors parathyroid hormone and prostaglandin E2.It has been hypothesized that vitamin K may reduce neuronal damage and that supplementation may hold benefits to treating Alzheimer's disease, although more research is necessary in this area
