Unverified维生素D3与K2应与钙同补，D3促进钙吸收、K2引导钙沉积到骨骼而非血管；单纯补钙不配K2可能增加血管钙化风险97% similarUnverified维生素D3补充首选与维生素K2（MK-7型）复配的产品，K2引导钙沉积到骨骼而非血管，单独补大剂量D3（＞4000IU/天）而无K2有软组织钙化风险96% similarUnverified补钙或补维生素D3时应同时补充维生素K2（MK-7），因D3促进钙吸收而K2引导钙沉积到骨骼、避免钙沉积在血管，二者协同才能真正降低骨质疏松风险96% similarUnverified维生素D3优先选择含K2（MK-7型）的复配产品，K2引导钙沉积到骨骼而非血管，单独大剂量补D3（≥2000IU）而不补K2可能增加动脉钙化风险95% similarUnverified钙需与维生素D3和维生素K2协同才能有效沉积到骨骼：D3促进肠道吸收，K2引导钙进入骨而非血管；单纯大量补钙不配D3/K2既效果差又增加动脉钙化风险95% similar
