Introduction
It is acceptable to take cod liver oil during menstruation, but it should be consumed in moderation. Cod liver oil is rich in vitamin A, which supports vision, immune system function, and mucous membrane health. It also contains vitamin D, which enhances calcium absorption, regulates bone health, and participates in immune modulation. Some cod liver oil products contain small amounts of Omega-3 fatty acids, which have anti-inflammatory properties and help regulate blood lipid levels, and generally do not cause increased menstrual bleeding.
Generally speaking, women can take cod liver oil during their menstrual period, but should do so in moderation. The detailed explanation is as follows:
Cod liver oil is rich in vitamin A, which helps maintain vision, immune system function, and mucous membrane health. It also contains vitamin D, which promotes calcium absorption, supports bone health, and participates in immune regulation. Some cod liver oil contains small amounts of Omega-3 fatty acids, which have anti-inflammatory properties and help regulate blood lipids. These components generally do not cause increased menstrual bleeding. If a woman does not experience significant discomfort during her period, such as dysmenorrhea or dizziness, moderate consumption of cod liver oil will not cause adverse effects.
However, it should be taken in moderation. Excessive intake of cod liver oil may irritate the gastrointestinal tract, causing discomfort such as abdominal pain and nausea. For women with heavy menstrual bleeding or abnormal coagulation function, although the Omega-3 content in cod liver oil is relatively low, individual sensitivities vary. If you naturally have heavy menstrual flow or suffer from conditions such as hemophilia or thrombocytopenia, it is recommended to discontinue use during menstruation to avoid potential anticoagulant effects that may worsen bleeding.
In addition to cod liver oil, women should also maintain a healthy diet during their menstrual period, consuming more warm foods such as millet porridge and steamed egg custard. They should avoid cold or cooling foods such as ice cream and crab. It's also important to moderately supplement with nutrients such as iron and protein. If abdominal pain worsens or abnormal bleeding occurs, discontinue use immediately and seek medical attention.
