    My son nearly died of Vitamin A poisoning. He never too handfuls of vitamins — he was 10. He had never previously taken vitamins at all, but that summer, his father gave him a bottle of One-A-Day multiples, so the kid took 1 daily. For HIM, it was a toxic dose. The pills contain the “standard” 5000 units per FDA, but in reality, WE are not standard. What is perfectly okay for YOU may be lethal to me. Where vitamins are concerned please, I beg of you, err on the side of extreme caution. Especially Vitamin A, which can kill you and has a long history of killing people including a of Arctic explorers who ate the liver of animals they killed and then died from Vitamin A overdoses. This is very very serious stuff and the American proclivity for taken LOTS of vitamins and assuming that more is always better is very dangerous. I know from painful, terrifying personal experience.
