What are Micronutrients?

Micronutrients are small but very important nutrients like vitamins and minerals. They help our body do many things. This includes making energy, staying healthy, growing, and fighting off sickness.

A good way to think of the difference is that macronutrients (like proteins and fats) are the main parts of our diet. But micronutrients are like the small pieces we need for our bodies to work well.

The Importance of Micronutrients

Micronutrients are the essential building blocks that support the body’s various physiological functions.

Think of vitamins as the helpers that keep our bodies running smoothly. They make sure our metabolism works right and help with many other processes. There are two types of vitamins: those that mix with water and the ones that mix with fat.

The water-soluble vitamins include vitamin C and the B vitamins. Since our bodies don’t store these, we need them from our daily diet. Fat-soluble vitamins, like A, D, E, and K, can be stored in our body fat.

Now, minerals are basically the rocks our bodies need for different things. They help keep our cells strong and working well. There are big minerals, called macrominerals, and little minerals, called trace minerals. We need both types for our health.

Macrominerals, found in larger amounts, do things like keep our bones strong and help our nerves. Trace minerals, needed in small doses, do other important jobs. For instance, they help carry oxygen in our blood and support our immune system.

Recommended Intakes

How much of each micronutrient we need changes with age, gender, and our health. It’s key to get enough of these nutrients, or we might get sick.

Research Findings

Several research studies have shown the positive impact of adequate micronutrient intake on health.

Studies on vitamins A and C suggest they can lower the chance of some cancers¹. Getting enough iron and copper might slow down Alzheimer’s¹. Low selenium can up the risk for heart issues¹. But raising selenium levels might lower the heart disease risk by 24%¹.

To stay healthy, make sure you get all the micronutrients you need. Eating a mix of healthy foods is the best way to do this. This keeps our bodies in good shape.

Types of Micronutrients

Micronutrients are vitamins and minerals that the body needs in small amounts. There are four main types: water-soluble vitamins, fat-soluble vitamins, macrominerals, and trace minerals.

Water-soluble Vitamins

Vitamins like C and B-complex vitamins dissolve in water. The body doesn’t store them, so it’s essential to get them from food often. Here’s how much you should aim to have every day:

• Vitamin B1 (thiamine): 1.1-1.2 mg
• Vitamin B2 (riboflavin): 1.1-1.3 mg
• Vitamin B3 (niacin): 14-16 mg
• Vitamin B5 (pantothenic acid): 5 mg
• Vitamin B6 (pyroxidine): 1.3-1.7 mg
• Vitamin B7 (biotin): 30 mcg
• Vitamin B9 (folate): 400 mcg
• Vitamin B12 (cobalamin): 2.4 mcg
• Vitamin C (ascorbic acid): 75-90 mg

Fat-soluble Vitamins

Fat-soluble vitamins are stored in the body’s fat. Some fat in your diet is needed to absorb these vitamins. They stay in the body longer and can cause problems if you have too much. Aim for these amounts daily:

• Vitamin A: 700-900 mcg
• Vitamin D: 15-20 mcg
• Vitamin E: 15 mg
• Vitamin K: 90-120 mcg

Macrominerals

Macrominerals are needed in larger amounts than trace minerals. They help keep your body’s structure and fluids in balance. Here’s how much you should get each day:

• Calcium: 1000-1200 mg
• Phosphorus: 700 mg
• Magnesium: 310-420 mg
• Sodium: 1500 mg
• Chloride: 1800-2300 mg
• Potassium: 2600-3400 mg

Trace Minerals

Though you need them in small amounts, trace minerals are crucial for many body functions. They include iron, manganese, copper, zinc, iodine, fluoride, and selenium. Here’s what you should get each day:

• Iron: 8-18 mg
• Manganese: 1.8-2.3 mg
• Copper: 900 mcg
• Zinc: 8-11 mg
• Iodine: 150 mcg
• Fluoride: 3-4 mg
• Selenium: 55 mcg

Each micronutrient type is important for your health. It’s best to eat different foods to get all these nutrients.

Functions of Micronutrients

Micronutrients are key players in our body’s functions. They aid in energy creation and keep our immune system strong. Without them, our health would suffer.

Water-soluble vitamins, like B vitamins, work with energy and cell tasks. They take the food we eat and turn it into the energy our body needs. B vitamins are a group that supports this process. Adults need different amounts of thiamine, riboflavin, niacin, and others. Their needs change based on their age and sex¹.

Fat-soluble vitamins A, D, E, and K are crucial for vital body tasks. Vitamin A helps with vision and growth. Vitamin D is essential for bones and the immune system. Vitamin E is an antioxidant, protecting our cells. Vitamin K is key for bloods to clot and healthy bones. Adults require different amounts of these vitamins. This depends on their age and gender¹.

Macrominerals are needed in bigger amounts than micronutrients. They are crucial for muscle function, nerve signals, and bone health. This group includes calcium, phosphorus, and more. Their roles are vital for our health. Adults have specific daily needs for these minerals based on their sex and age¹.

Trace minerals are equally essential but needed in smaller doses. They include iron, copper, and more. These minerals aid in oxygen circulation, hormone production, and defense against disease. They are key for growth, a strong immune system, brain development, and other crucial tasks in the body. The exact amounts needed differ for each trace mineral¹.

On the whole, micronutrients are vital for top-notch health and the smooth operation of our bodies. They are key for making energy, keeping our immune system working, maintaining bone health, helping blood clot, and more¹.
