What are the Side Effects of Vitamin E Overdose ?
In November, 2004, the American Heart Association stated that high amounts of vitamin E can be harmful. Taking 400 IU per day, or higher, may increase the risk of death. Taking smaller amounts, such as those found in a typical multivitamin, was not harmful. High doses have also been reported to cause (or may theoretically cause) the following vitamin E side effects: * Nausea * Diarrhea * Intestinal cramping * Fatigue and weakness * Headaches * Blurred vision * Any unusual bruising or bleeding (vitamin E can increase the risk of bleeding) * Signs of gastrointestinal bleeding, such as: o Black, tarry stools o Bright-red blood in the stool o Vomiting of blood * Signs of a hemorrhagic stroke (bleeding in the brain), such as: o Vision or speech changes o Weakness or numbness in an arm or leg o Severe headache. Some people may experience irritation or allergic reactions when vitamin E is applied to the skin.
