Taking large doses of certain vitamins and minerals can cause toxicity, warns WebMD. Vitamins A, E and K, and the minerals selenium and iron are most likely to cause toxicity if taken in excess. Vitamin B-6 can also cause neuropathy if taken in excess. The upper tolerable limit of vitamin A is 10,000 international units per day, and taking more than that can cause serious health problems and possibly death.
Symptoms of vitamin A toxicity include nausea, fatigue and swelling of the brain, says Mayo Clinic. Chronic consumption of excessive amounts of vitamin A can lead to psychiatric changes and osteoporosis. In severe cases of vitamin A toxicity, liver damage and death may occur.
