What vitamin excess is a specific risk associated with taking high amounts of cod liver oil supplements?
Answer
Vitamin A toxicity
Cod liver oil is highly concentrated in fat-soluble vitamins, specifically Vitamin A and Vitamin D. A significant drawback for consumers taking supplements alongside a diet that already includes fortified foods or cod liver is the potential for excessive intake of Vitamin A. Since Vitamin A is fat-soluble, the body stores the excess amounts rather than excreting them readily, leading to chronic high intake which can cause toxicity symptoms, including nausea, dizziness, and blurred vision, potentially resulting in liver damage over prolonged periods.
