8 daily habits that seem healthy, but do more harm than good

They’ll keep you and your family healthy, right? Maybe not. Too much iron can cause nausea and vomiting, and if you overdo the vitamin C, it can lead to nausea, diarrhea, and stomach cramps. Too much vitamin A can cause vision problems, among other things. Excess vitamin D can make muscles weak, and it can even lead to heart problems. And vitamins K and E can cause bleeding issues. You and your family should stick to the daily dose, and nothing more.
