Thorne Research - Vitamin K - Vitamin Supplement - 60 Capsules
Many people think of vitamin K as the vitamin that supports the normal and healthy ability of the blood to clot. But vitamin K also supports strong bones and healthy arteries. Vitamin K “pairs up” with vitamin D in the body, much like magnesium pairs up with calcium. The result is that vitamin K and magnesium can both help keep calcium in the bones and out of the blood vessels and other soft tissues. 3-K Complete includes the clinically studied forms of vitamin K1 and vitamin K2 (as MK-4 and MK-7). 3-K Complete contains significantly more MK-4 than most other multiple-K products on the market, while the MK-7 is MenaQ7 – used in the majority of MK-7 research. The body’s activation of important proteins – via a process known as carboxylation – appears to be at the center of most of vitamin K’s therapeutic benefits. When vitamin K is present as a co-factor, the proteins activated in this vitamin K-dependent carboxylation process include multiple blood-clotting proteins (prothrombin and others), bone mineralization proteins (osteocalcin and calbindin), and the vascular calcification inhibitor protein (matrix Gla-protein). 3-K Complete offers support for bone, cardiovascular, and metabolic health. It also offers nutritional support for oncology patients.
