What Vitamins Can Be Toxic to the Liver

Although vitamins are good in their recommended dosages, vitamins in excessively large quantities can be toxic and cause damage to the body. There are several kinds of vitamins that can cause vitamin toxicity. Symptoms include gastrointestinal disturbances, headache, fatigue, muscle and joint pain, dry skin, weight loss and more.

  1. Vitamin A

    • Vitamin A toxicity will show itself in various signs and symptoms. Some of these include rashes, drowsiness, nausea, vomiting, irritability, headache and abdominal pain. In some cases, peeling skin is also an issue.

    Vitamin B3

    • Dosages of Vitamin B3 in amounts of over 500 mg per day can damage the liver. Prolonged ingestion must occur before symptoms manifest.

    Vitamin C

    • Although it is rare, Vitamin C in amounts that exceed 2,000 mg per day can be toxic and affect the liver. Toxicity symptoms include diarrhea, bleeding gums, dry hair, delayed wound healing and dry skin.

    Vitamin D

    • Vitamin D toxicity, otherwise known as hypervitaminosis D, causes hypercalcemia. Hypercalcemia occurs when high levels of calcium are stored in the body. Some symptoms of Vitamin D toxicity include a decreased appetite, constipation, kidney stones, weakness confusion, and heart rhythm disturbances.

    Vitamin E

    • Nausea, weakness, fatigue, abdominal pain, diarrhea, headache and gas are all symptoms of too much Vitamin E in your system which is a potential cause of liver damage.
