Ensuring you get enough vitamins and minerals is crucial for maintaining overall health, but many people don't realize they may be falling short. In the US, poor diets are a mainstream phenomenon. About 75% of Americans don’t consume the recommended servings of fruit and more than 80% don’t consume enough vegetables. When it comes to deficiencies, almost all Americans have some. 94.3% of the US population doesn’t meet the requirement for vitamin D, 52.2% for magnesium, 44.1% for calcium, 43% for vitamin A, and 38.9% for vitamin C. 

Recognizing the signs of these deficiencies can help you take proactive steps to improve your diet and well-being. Here are seven key indicators that you might need more vitamins and minerals in your diet.
