The subjects with hyperhomocysteinemia (plasma homocysteine >15 ？gmole/L) and normal vitaminB6, B12 status will invite to this intervention. The exclusion criteria are: B-vitamin supplement use, serum creatinine concentration >=1.5 mg/dl. All blood samples collected and measure the concentration of homocysteine, folate, B6 and riboflavin. The association of the status these B vitamins in CVD patients will be investigated.葉酸維生素B2同半胱胺酸中風白內障folatevitB2homocysteinestrokecataract
