    Vitamin A is one of the most common nutrients that can harm the liver. An excess (typically from supplements) can cause storage of fat in the liver, chronic hepatitis and cirrhosis. Patients with chronic liver disease should consume less than 2500 IU of vitamin A per day in pill form (getting vitamin A through food seems okay).

    A list of other nutrients and supplements that have been shown to have toxic effects on the liver:
    1. Nicotinic acid (niacin; Nicolar)
    2. Pennyroyal oil
    3. Senna fruit extracts
    4. Valerian
    5. Iron
    6. Mistletoe
