Introduction
Cod liver oil and vitamin D generally should not be taken together. Cod liver oil mainly contains vitamin A and vitamin D3. Common forms of vitamin D include vitamin D2 and vitamin D3. Taking them simultaneously may lead to excessive intake of vitamin D3, causing toxicity, resulting in gastrointestinal discomfort or urinary system symptoms, and in severe cases, adverse respiratory reactions.
Fish liver oil and vitamin D generally should not be taken together, as this may lead to excessive intake of vitamin D and result in toxicity. The details are as follows:
Fish liver oil is a medication used to treat night blindness, rickets, and infantile tetany, with its main components being vitamin A and vitamin D3. Vitamin D comes in various forms, the more common ones being vitamin D2 and vitamin D3. Taking both simultaneously may cause an excessive intake of vitamin D3, leading to symptoms of poisoning such as loss of appetite, nausea, constipation, and other digestive discomforts, or increased urination, thirst, and hematuria affecting the urinary system. In severe cases, it may even trigger respiratory adverse reactions such as coughing and difficulty breathing.
It is advisable to choose only one of these supplements and strictly follow medical instructions regarding proper method and dosage, which helps enhance the drug's effectiveness.
