For example, too much vitamin A can cause headaches and liver damage, reduce bone strength, and cause birth defects. Too much iron causes nausea and vomiting and can damage the liver and other organs. Too much vitamin C or zinc can cause nausea, diarrhea, and stomach cramps. Excess selenium can cause hair loss, gastrointestinal discomfort, fatigue, and mild nerve damage.
