Answer

Folic acid supplements won't relieve heavy periods. The problem with having heavy periods is that you can develop anemia — a condition in which you don't have enough healthy red blood cells to carry adequate oxygen to your tissues.

Many types of anemia exist, including ones related to vitamin deficiencies. But the type that's most commonly associated with heavy periods is iron deficiency anemia. With iron deficiency anemia, heavy periods lead to blood loss over a long time, which depletes your body's iron stores.

If your doctor suspects that you have anemia as a result of heavy periods, your doctor may recommend:

  • A blood test, to check your iron level and confirm that the cause of your anemia is iron deficiency.
  • An iron supplement, to rebuild you body's iron stores. Your doctor may recommend also taking a daily vitamin containing folic acid, vitamin C, vitamin B-12 and other vitamins that help build red blood cells.

A number of conditions can cause heavy menstrual bleeding. Hormonal imbalance, uterine fibroids or certain types of intrauterine devices are just a few.

If you have heavy menstrual bleeding, talk with your doctor for more information and guidance.
