What are the 5 nutrient deficiencies that cause fatigue?

There are five nutrients that are essential for good health, and each of them can be a source of fatigue. When your body doesn’t have enough of one or more of these nutrients, it can lead to fatigue.

The five nutrients that cause fatigue are:

Iron: Iron is important for energy production and tissue growth. If your body doesn’t have enough iron, you may experience fatigue due to anemia.

Magnesium: Magnesium is involved in many chemical reactions in the body and is needed for nerve function and muscle contractions. Magnesium deficiency can lead to fatigue due to magnesium deficiency anemia.

Zinc: Zinc is important for the production of insulin, testosterone, and other hormones. If your zinc levels are low, you may experience symptoms such as fatigue and poor immune system function.

Copper: Copper is responsible for connecting different chemicals in the body and helps to form connective tissue. Copper deficiency can lead to fatigue due to copper deficiency anemia.

What are the symptoms of these deficiencies?

There are many different nutrient deficiencies that can cause fatigue. Some of the symptoms of these deficiencies include:

  1. Weakness

  2. Low energy levels

  3. Difficulty concentrating

  4. Poor performance at work or school

It is important to get tested for these deficiencies if you are feeling fatigued. If you have any of these symptoms, it is important to see a doctor determine the source of your fatigue and find the best way to improve it.

Foods to improve your natural nutrient levels

One of the most common causes of fatigue is nutrient deficiency. If you are not getting the nutrients your body needs, you will experience fatigue.

There are many foods that contain nutrients that can help improve your natural levels of these nutrients. Some of the most common foods that contain nutrients that can help to improve fatigue include eggs, fish, leafy greens, fruits, and vegetables.

Eggs are a great source of protein and choline, which are two important nutrients for improving fatigue. They also contain vitamins B12 and D, which can help to support your mood and energy levels.

Fish is another great source of nutrients that can improve your fatigue. Not only do they provide important omega-3 fatty acids, but they also contain vitamin B12, choline, and zinc.

Leafy greens are a good source of antioxidants and other essential vitamins and minerals.

Fruits are also good sources of nutrients that can improve your fatigue. They contain antioxidants, fiber, vitamins, minerals, and other essential nutrients.

Who is most at risk for these deficiencies?

  • Certain deficiencies are most often seen in people who have difficulty digesting food or who have poor absorption rates for those nutrients.

  • People who are overweight or obese also tend to suffer from more nutrient deficiencies due to their increased body weight.

  • Other people who are at risk for nutrient deficiencies include pregnant women, people who are taking certain medications, and people who are fasting or abstaining from food for religious reasons.

It is important to speak with a health professional if you suspect you may have a deficiency in any of these nutrients. He or she can test you for the deficiency and recommend treatments if necessary.


If you're feeling chronically exhausted, there is a good chance that you are deficient in some key nutrients. Deficiencies can lead to fatigue, lack of energy, and even mood swings. If you don't feel like your diet gives you the nutrients your body needs, make sure to include a variety of nutrient-rich foods in your daily routine.
