I took a health and nutrition class a few years back and remember reading about vitamins. The chapter talked about deficiencies and having too much. I’m trying to remember the word for too much. I don’t think it was toxicity, but they are synonymous.
Too much of one vitamin can cause toxicity, which is almost like poison. It’s an overdose.
Too much of a specific vitamin can put other vitamins out of balance.
I don’t know that I answer that right–oh–I know–if you take too much vitamin A, it’s called hypervitaminosis A. Hyper means too much. It could cause hypovitaminosis of another vitamin. Hypo means too little. It may not cause hypovitminosis of all your other vitamins, just the one it competes with. Vitamins have their own intricate balance.
It’s been years since I studied that, so hypervitminosis A may now be called Avitminosis. Hope I have you one the right track.
