Feature Summary
Vitamin K2, D3 and A provides clinically relevant doses of the three fat-soluble vitamins essential to optimal bone health. Although needed for cardiovascular health, blood sugar regulation, immune function, and inflammation control, vitamins A, D, and K2 have complementary physiological bone-related functions, such as modulating gene expression in osteoblasts and carboxylating osteocalcin, an enzyme needed for bone formation.1 This is exemplified by a reduction in undercarboxylated osteocalcin and an increase in bone mineral density (BMD) in postmenopausal women when vitamin K is added to vitamin D supplementation.2,3,4
Vitamin D has diverse and significant functions in multiple body systems, and widespread deficiency magnifies these crucial roles.5,6 Supplementation is associated with a well-established reduction in osteoporotic fracture when taken daily at a clinically relevant dose.7,8 Correcting a vitamin D deficiency is critical when supplementing with vitamin A, as vitamin A appears to promote bone health if vitamin D levels are adequate.9,10,11 Additionally, maternal vitamin A levels during pregnancy have been associated with the peak bone mass and bone strength of their children, highlighting the unrecognized importance of vitamin A for lifelong bone health, in parallel to the effect of vitamin D on peak bone mass.12,13 Vitamin K is now recognized as necessary for the carboxylation of enzymes critical for both bone and blood vessel health.14-18 Indeed, meta-analysis has shown an improvement in vertebral bone mineral density (BMD) and a reduction in fracture among postmenopausal women with osteoporosis, while controlled trial data shows a reduction in the age-related decline in BMD among healthy postmenopausal women.19,20 The naturally derived MK-7 form in Vitamin K2, D3 and A has a longer half-life than any other form.21,22

Drug Interactions
Vitamin K may antagonize the effect of some anticoagulant medications, and concurrent use should be medically supervised. When taken with a thiazide medication (diuretic), vitamin D may increase the risk for hypercalcemia. Also, vitamin D may improve insulin sensitivity and lower blood pressure, requiring a reduction in dosage of hypertension and/or diabetic medications. Vitamin A should not be taken with other synthetic retinoids, such as acitretin or bexarotene.
