Can I drink matcha during my menstrual period?
Generally speaking, it is acceptable to consume matcha during menstruation, but moderate intake is recommended. The detailed explanation is as follows:

Matcha is rich in various trace elements, such as iron, potassium, protein, and vitamin C. Moderate consumption can help supplement essential nutrients and enhance immunity. The chlorophyll and dietary fiber in matcha aid intestinal motility and digestion, which can help alleviate potential loss of appetite in women during their menstrual period.
Matcha contains relatively high levels of caffeine; excessive intake may affect the central nervous system, leading to discomforts such as insomnia and anxiety. Additionally, overconsumption of matcha may cause gastrointestinal issues like abdominal pain and diarrhea. Therefore, it's important to consume matcha in moderation.
During menstruation, maintaining healthy eating habits and consuming more foods rich in iron and fiber can help alleviate menstrual discomfort. It's also important to eat more fresh vegetables and fruits to support overall health.
