Vitamins and minerals are micronutrients that allow our body to function and live. They affect things from vision and bone strength to blood clotting.
Vitamins are organic, meaning they are carbon-based compounds. Our bodies can make some vitamins, but to get proper amounts, we need to eat or take in the 13 essential vitamins.
Dietary minerals are not created by living organisms. Calcium, phosphorus, potassium, sodium, and magnesium are the 5 major minerals. The 8 trace minerals, including iron used in our blood, have specific and important roles on a smaller scale.

3 tips to make sure you're getting enough vitamins and minerals:
1) Eat a variety of colors in your 5 daily servings of fruits and vegetables
2) Read nutrition labels to learn which foods are good sources
Though taking a multivitamin can help you reach micronutrient needs, they are often unnecessary, and it is harder to oversupplement with food sources alone. Ask your doctor if you should be taking a multivitamin.
