New studies are looking at the synergistic effects of vitamin K (specifically, vitamin K2) and vitamin D in the area of both cardiovascular health and bone strength. There are many studies that add weight to the argument that we should all watch our intake of both of these vitamins. As many as 60 percent of the UK population is vitamin D deficient and low levels have been linked to serious health problems in later life. Similarly, many experts now believe that a subclinical vitamin K deficiency, that is, one that is not great enough to hinder blood clotting capacity, could be wide-spread and could contribute to osteoporosis, and other age-related diseases. Lamberts® Vitamins D3 and K2 provides a full 1000iu (25µg) of natural vitamin D3 cholecalciferol) as well as an impressive 90µg of vitamin K2 in the form of Menaquinone (MK-7).

Those on anti-coagulant medication (blood thinners), that wish to take levels of 100µg of Vitamin K or more, should consult with their doctor first.
