25-hydroxyvitamin D + menaquinone-7

This is a combination dietary supplement containing two active ingredients: 25-hydroxyvitamin D (commonly known as vitamin D3 or cholecalciferol) and menaquinone-7 (MK-7), a form of vitamin K2. The supplement is designed to address deficiencies in both vitamins, which play complementary roles in bone and cardiovascular health. Vitamin D3 enhances calcium absorption from the gut and supports bone mineralization, while MK-7 activates proteins involved in calcium transport and inhibits vascular calcification by promoting carboxylation of matrix Gla-protein. This combination is marketed for individuals with low levels of both vitamins to support bone strength and potentially reduce arterial calcification risk[1][2][5]. It is available over-the-counter as an oral supplement.
