What happens if you have too much micronutrient?

Excessive intake of micronutrients can lead to toxicity, which varies depending on the specific nutrient. For example, too much vitamin A can cause liver damage and vision problems, while excessive iron can result in organ failure. Symptoms of micronutrient overdose may include nausea, headaches, and digestive issues. It's essential to maintain a balanced diet to avoid both deficiencies and excesses of these vital nutrients.
