I was recently reading about nutritional or dietary supplement medicines or pills most of them contain wide range of vitamins and minerals essential for well being of a human being and are used to treat and prevent vitamin and mineral deficiency in body.
But I also noticed that they are having their side effects also, like nausea, vomiting, diarrhoea and an upset stomach.
So the question is why do these supplement medicines are having their side effects? although they are temporary. Is it because sudden intake of all the vitamins and minerals or any other reason?
