Folic acid can delay menstruation

Taking folic acid generally does not cause delayed menstruation. The menstrual cycle is affected by many factors. As a water-soluble vitamin, folic acid usually does not interfere with the endocrine system at normal doses.

Folic acid is an essential B vitamin for the human body and participates in physiological processes such as DNA synthesis and red blood cell production. The usual supplement dosage is 0.4-0.8 mg/day, and no direct effect on the menstrual cycle has been found in this dosage range. Delayed menstruation is more likely to be related to factors such as stress changes, weight fluctuations, work and rest disorders, or gynecological diseases. When women preparing for pregnancy or during pregnancy take folic acid as directed by their doctor, if they experience menstrual abnormalities, they should promptly investigate other causes.

In rare cases, long-term use of high doses of folic acid may interfere with zinc metabolism and indirectly affect hormone levels. However, such effects may only occur if daily supplementation exceeds 1 mg, and ordinary meals and regular supplements are well below this threshold. If menstrual irregularities persist after taking folic acid, it is recommended to check for potential diseases such as polycystic ovary syndrome and thyroid dysfunction.

Maintaining a regular schedule and a balanced diet can help maintain a normal menstrual cycle. It is recommended to consume 400 micrograms of folic acid every day and pay attention to supplementing iron-rich foods such as animal liver, spinach, etc. Avoid excessive dieting or strenuous exercise, manage emotional stress, and keep track of changes in your menstrual cycle. If menstruation is delayed for more than 7 days or is accompanied by symptoms such as abnormal bleeding and abdominal pain, you need to seek prompt medical treatment for hormone level testing and gynecological examination.
