What Are Trace Minerals and Why Does the Body Need Them?

Introduction

Your body needs many different nutrients to stay healthy, including vitamins, protein, healthy fats, carbohydrates, and minerals. Among these important nutrients are trace minerals.

Although your body only needs trace minerals in very small amounts, they play important roles in normal body functions. They help support processes such as oxygen transport, immune function, thyroid activity, metabolism, antioxidant protection, and the formation of healthy blood cells.

So, what exactly are trace minerals, and why does the body need them?

In this article, we will explain trace minerals in simple terms, look at some of the most important trace minerals, discuss where you can get them, and explain why maintaining adequate mineral intake is an important part of a healthy lifestyle.

What Are Trace Minerals?

Trace minerals are minerals that the human body needs in relatively small amounts compared with major minerals. Minerals are naturally occurring elements that your body uses for many biological processes. Some minerals are required in larger amounts and are commonly called macrominerals, while others are needed in smaller amounts and are called trace minerals.

Common trace minerals include:

• Iron
• Zinc
• Copper
• Selenium
• Iodine
• Manganese
• Chromium
• Molybdenum

Even though the required amounts may be small, these minerals can have important jobs throughout the body. Think of trace minerals like small but essential pieces of a larger puzzle. You may not need a large quantity of each one, but your body still depends on them to perform specific functions properly.

Why Does the Body Need Trace Minerals?

Trace minerals participate in many processes that help keep the body functioning normally.

1. They Help Support Metabolism

Your metabolism involves the chemical processes your body uses to convert food into energy and maintain normal cellular functions.

Certain trace minerals, including chromium, manganese, and molybdenum, are involved in enzymes and metabolic pathways.

A balanced diet that provides essential nutrients helps give your body the materials it needs for these processes.

2. They Support Normal Immune Function

The immune system relies on a variety of nutrients to function normally.

Zinc, selenium, iron, and copper all have roles related to normal immune function.

For example, zinc is involved in numerous cellular processes, while selenium contributes to antioxidant systems in the body.

This is one reason a nutritious, varied diet is important for maintaining overall wellness.

3. They Help With Oxygen Transport

Iron is one of the best-known trace minerals because of its important role in making hemoglobin.

Hemoglobin is a protein in red blood cells that helps transport oxygen throughout the body.

When the body does not have enough iron, it may not be able to produce enough healthy hemoglobin. Iron needs vary depending on factors such as age, sex, and life stage.

4. They Support Thyroid Function

Iodine is an essential trace mineral that the thyroid gland uses to produce thyroid hormones.

Thyroid hormones help regulate important processes throughout the body, including metabolism and energy use.

Both too little and too much iodine can be problematic, which is why more is not necessarily better when it comes to minerals.

5. They Provide Antioxidant Support

Some trace minerals are involved in antioxidant enzymes that help protect cells from oxidative stress. Selenium, copper, zinc, and manganese are involved in different antioxidant systems within the body. This does not mean that taking large amounts of these minerals provides extra protection. The goal is to obtain appropriate amounts through a balanced diet and, when appropriate, supplementation under professional guidance.

How Can You Get Trace Minerals Naturally?

One of the best ways to obtain essential minerals is by eating a varied, nutrient-dense diet.

Consider including a combination of:

• Vegetables and fruits
• Beans and lentils
• Whole grains
• Nuts and seeds
• Eggs
• Dairy products or fortified alternatives
• Seafood
• Lean meats or other protein sources

Eating a variety of foods is helpful because different foods provide different nutrients. For example, seafood can provide iodine and selenium, while beans can provide iron, copper, and manganese.
