In addition to these benefits, vitamin D3 also promotes calcium absorption.*.

It is important for optimal bone, cardiovascular, and immune health.*.

Vitamin D3 functions as a hormone, a chemical messenger with widespread effects in the human body.* This product is specially formulated to contain both vitamin D3 and vitamin K2.These findings indicate that combined administration of vitamin D 3 and vitamin K 2, compared with calcium administration, appears to be useful in increasing the BMD of the lumbar spine in postmenopausal women with osteoporosis. Two-way ANOVA with repeated measurements showed a significant increase in BMD in the D and K groups compared with that in the C group ( P < 0.05 and P < 0.001, respectively), and a significant increase in BMD in the DK group compared with that in the C, D, and K groups ( P < 0.0001, P < 0.05 and P < 0.01, respectively).

One-way analysis of variance (ANOVA) with repeated measurements showed a significant decrease in BMD in the C group ( P < 0.001).

There were no significant differences in age, body mass index, years since menopause, and initial BMD among the four groups. BMD of the lumbar spine (L2–L4) was measured by dual energy X-ray absorptiometry at 0, 1, and 2 years after the treatment started. Ninety-two osteoporotic women who were more than 5 years after menopause, aged 55–81 years, were randomly divided into four administration groups: vitamin D 3 (1α hydroxyvitamin D 3, 0.75 μg/day) (D group n = 29), vitamin K 2 (menatetrenone, 45 mg/day) (K group n = 22), vitamin D 3 plus vitamin K 2 (DK group, n = 21), and calcium (calcium lactate, 2 g/day) (C group n = 20). The effect of the combined administration of vitamin D 3 and vitamin K 2 on bone mineral density (BMD) of the lumbar spine was examined in postmenopausal women with osteoporosis.
