I have been taking 1mg of folic acid since beginning march this year. planning of a pregnancy. is the amount of folic acid enough? and should i take any other vitamins?

Sounds ok, but...: Depending on local issues (such as how much folate is added to foods) the recommended dose for women's folate supplements are ~400 mcg/day for those who might become pregnant, 400-600 mcg/day for those already pregnant, and 4-5 mg/day (10 times more) for women at high risk for getting a baby with a neural tube defect. One can ask her primary care or Ob-Gyn doctor for advice and details.
