Research Progress on the Association between Vitamin,Calciumand Combined Intake and the Risk of Primary Osteoporosis
Studies have shown that vitamin and combined calcium intake is associated with osteoporosis(OP),but there is a lack of effective integration of relevant research evidence.This paper reviews the correlation between vita-min,calcium combined intake and the risk of primary OP by combing relevant literature.The analysis found that diet-ary or serum vitamin D,E,K,C and B levels were associated with OP,but there was no consistent association be-tween vitamin A and OP risk.Combined intake of multiple vitamins,synergistic intake of calcium and vitamin D,and synergistic intake of calcium,VD and VK have protective effects on OP.Relevant health policies and clinical guide-lines stipulated the reference intake or therapeutic dose of each vitamin,but there is a lack of relevant health policies that"adapt to local conditions".
