                                According to the National Institutes of Health, the tolerable upper intake level for adults is 40 mg of zinc per day, and exceeding this amount can lead to adverse health effects. This makes it clear that while zinc is an essential nutrient, taking it every day can be harmful if the dosage is too high and sustained over time. The danger lies in chronic overconsumption, typically from supplements, not from food sources alone.
