Even though calcium is one of the most important as well as the most abundant minerals in the body, the proper function of our bodies heavily depends on other minerals as well. This article presents the 7 often overlooked minerals, the reason they are so important, and the best dietary sources.

1. Magnesium

Besides supporting bone health, magnesium is important for a transmission of nerve impulses and maintaining normal muscle function. Muscle cramps and irregular heartbeat are the most common symptoms of deficiency in this mineral and people with GI problems, such as Crohn`s and celiac disease, are most prone to magnesium deficiency.

Best sources:  Seafood, spinach, soy milk, nuts, yogurt, and black beans.

2. Iodine

Iodine is non-metallic trace element and it is needed for the production of thyroid hormone. Deficiency in iodine leads to goiter, commonly known as an enlarged thyroid gland. The body does not make iodine, so it is an essential part of your diet.

Best sources: Seafood, iodized table salt, and sea vegetables like kelp.

3. Selenium

Selenium is yet another important dietary mineral, and we require a small amount of it in our diet. It has antioxidant properties, which makes it very effective at reducing inflammation. Selenium deficiency is linked to various health issues, including male infertility and heart disease.

Best sources:  Fruits, vegetables and grains grown in selenium-rich soil, shellfish, and meat.

4. Potassium

This mineral is important for helping your muscles contract and maintaining a steady heartbeat. It also promotes nerve cell function and it is included in chemical processes.  Potassium deficiency causes fatigue, feeling fait, or heart palpations.

Best sources:  Avocados, bananas, orange juice, honeydew melon, and potatoes.

5. Zinc

From a food standpoint, zinc may be a less familiar dietary mineral than calcium or potassium, but it is no less important to our metabolism. It assists in many activities, including nutrient metabolism, insulin function, and digestion. It is needed for normal development in children and it boosts the immune system as well.

Best sources: Yogurt, beef, pork, and oysters.

6. Chromium

Chromium is an essential mineral that plays a role in how insulin helps the body regulate blood sugar levels. Besides helping with a regulation of blood sugar, it also helps with metabolism of lipids and carbohydrates.

Best sources: Apples, grape juice, broccoli, whole-grain products, and meat.

7. Iron

Iron is a component of hemoglobin, a protein molecule which is found in red blood cells and carries oxygen from the lungs to body`s tissues. Deficiency in iron is linked to anemia and symptoms like headaches, fatigue, and weakness.

Best sources: Shellfish, red meat, greens like Swiss chard and spinach, tofu, and poultry.
