If a patient has elevated homocysteine, it is useful to take folic acid tablets. Generally speaking, it is recommended that patients can take small doses over a long period of time, such as 0.4-0.8 mg once a day, to help reduce homocysteine levels. If homocysteine is only mildly elevated, patients can also improve their lifestyle by eating more fresh fruits and vegetables, especially green leafy vegetables, which are rich in folic acid and can help reduce homocysteine levels. If an elderly person eats less on a regular basis and is not a big fan of fresh fruits and vegetables, the only way to lower homocysteine levels is to take oral folic acid tablets. Some people with H-type hypertension are also advised to take folic acid tablets in combination with antihypertensive medication.
