What vitamin over-doses would be most harmful to a fifteen-year-old boy? please list as many possible!
5 doctors weighed in across 2 answers
Iron: The most dangerous ones i can think of would be iron and vitamin a, but anything could theoretically be toxic in an extreme dose. If you have any questions please call poison control.

A, D, E, B6, Iron: One can consume too much of the fat-soluble vitamins a, d & e, but one has to take massive amounts to get into trouble. Taking 25, 000 units of a for many months can be toxic. Vit d toxicity has not been reported with doses under 40, 000 iu/day. Doses of e over 1500 iu/day may cause bleeding. B6 over 250 mg/day can cause neuropathy. While not a vitamin, over 1000 mg of elemental iron is dangerous.
