Though we often only hear about calcium, our bodies actually require a variety of minerals to function properly. From digestion to supporting thyroid health to building strong bones, they play a role in just about everything. Here are 7 that are often overlooked, why they’re so important and the best dietary sources.
Like calcium, magnesium is also needed to support bone health and is quite critical for normal muscle function and transmission of nerve impulses. If you’re deficient, symptoms include muscle cramps and an irregular heartbeat. People with GI problems (like celiac and Crohn’s disease) are more at risk of being deficient in this crucial mineral.
Best sources: Spinach, black beans, nuts, soy milk, yogurt, and seafood.
Potassium is essential for maintaining a steady heartbeat and helping your muscles contract. It also assists chemical reactions and promotes nerve cell function. A drop in your potassium level can lead to heart palpitations, fatigue, or feeling faint.
Best sources: Orange juice, bananas, potatoes, honeydew melon, and avocados.
Iodine is a component of the thyroid hormone thyroxine and is crucial for normal function of your thyroid. Profound iodine deficiency is commonly associated with goiter, or an enlarged thyroid gland.
Best sources: Iodized table salt, seafood, and sea vegetables like kelp.

Iron is a critical component of hemoglobin, which is found in red blood cells. Hemoglobin carries oxygen from the lungs to tissues throughout the body. Iron deficiency is associated with anemia and symptoms like weakness, fatigue, and headaches.
Best sources: Red meat, poultry, tofu, greens such as spinach and Swiss chard, and shellfish.
Zinc is required for the function of many enzymes, which are the workhorses of all cells. Some of these critical activities include digestion, insulin function, and nutrient metabolism. It also helps boost the body’s immune system and is required for normal development in children.
Best sources: Oysters, beef, pork, and yogurt.
Best sources: Meat; shellfish; and fruits, vegetables, and grains grown in selenium-rich soil.
Chromium helps with the metabolism of carbohydrates and lipids, as well as the regulation of blood sugar. As a result, chromium is often marketed as a weight-loss supplement, although clinical data to support those claims is lacking.
Best sources: Meat, whole-grain products, broccoli, grape juice, and apples.
