Emerging research highlights the importance of optimal intake of vitamin K and its critical role in maintaining bone and cardiovascular health. Composed of a group of naturally occurring and structurally similar, fat-soluble vitamins, vitamin K is required for the proper utilization of calcium and helps to bind newly absorbed calcium to the bone matrix. Vitamin K helps maintain bone mineral density by decreasing the activity of osteoclasts, cells that break down bone. It also provides critical cardiovascular protection by activating matrix Gla protein (MGP), a potent inhibitor of circulatory calcification. Along with vitamin D, another key nutrient required for overall wellness, these two nutrients act in synergy to support and maintain bone and cardiovascular health. Current research has found high concentration supplementation, at 180 mcg/day, results in improved clinical results compared to lower-dose supplementation.
K-FORCE provides 180 mcg of MenaQ7® PRO, the most widely studied form of vitamin K2 as MK-7, along with 5,000 IU of vitamin D3 for optimal support of bone and cardiovascular health.

Vitamin K Depletion
Calcium and vitamin D are important mediators in bone growth, but vitamin K plays an equally important role. The synthesis of bone growth is dependent on vitamin K, through its carboxylation of osteocalcin, a protein secreted by osteoblasts. Osteocalcin guides calcium into bones and prevents its absorption into organs, joint spaces and arteries. Vitamin K occurs in two main forms: K1 (phylloquinone), derived from foods such as green leafy vegetables and K2 (menaquinone), which is a group of related compounds differentiated by their side chains. Numerous studies have shown that vitamin K2 as MK-7 is the more bioavailable form of the nutrient 7 and more powerfully influences bone building than K1.
Supplementation of K2 has repeatedly been shown to help maintain bone density and strength among women. Research conducted on Japanese populations has found superior bone health among women who more frequently consumed MK-7-rich nattō than those who did not.
Cardiovascular Health and Blood Sugar Balance
Vitamin K also plays a key role in supporting the cardiovascular system and healthy blood sugar balance. In a large population study, those who consumed high amounts of K2 had significantly improved cardiovascular markers compared to those given vitamin K1.
