Can I take vitamin B complex during my menstrual period?
Generally, it is acceptable to consume B-complex vitamins in moderation during menstruation, but their use should be guided by a physician. The detailed explanation is as follows:
B-complex vitamins are water-soluble vitamins and essential nutrients that include various components such as vitamins B1, B2, B6, and B12. These vitamins play important physiological roles in the human body.

During menstruation, women's bodies are in a special physiological state, and moderate supplementation of B-complex vitamins offers many benefits. B-complex vitamins are involved in energy metabolism and can alleviate fatigue commonly experienced during menstruation. Vitamin B6 helps regulate hormone levels in the body and can relieve emotional anxiety or breast tenderness associated with premenstrual syndrome. Vitamin B12 and folic acid can help prevent anemia and are especially suitable for women with heavy menstrual flow.
Although B-complex vitamins benefit women during menstruation, excessive intake may cause adverse effects. Overconsumption of B-complex vitamins may burden the gastrointestinal tract, causing symptoms such as bloating, abdominal pain, nausea, and other gastrointestinal discomforts. It may even lead to skin allergies. Therefore, these vitamins should be taken under medical supervision or according to the recommended dosage on the product label.
During menstruation, women should maintain a balanced diet and prioritize obtaining B-complex vitamins from food sources such as whole grains, lean meats, and leafy green vegetables. If additional supplementation via medication is needed, it is advisable to consult a physician to avoid blindly taking medications that may disrupt normal physiological conditions.
