Fatigue… it’s not always a sign of lack of rest or overwork. In many cases, that constant feeling of exhaustion can be related to an imbalance in the body’s vitamin and mineral levels. In this article, we’ll explain how to identify if your fatigue may be due to a vitamin deficiency and what laboratory tests can help you understand your health status.

What is chronic fatigue?

The chronic fatigue it’s a state of physical and mental fatigue that doesn’t improve with rest and can last for weeks or even months. It’s often confused with occasional fatigue, but when it becomes constant and interferes with your daily activities, it could indicate an underlying health problem.

Among the most common causes of chronic fatigue are:

• Sleep disorders
• Prolonged stress
• Anemia
• Thyroid problems
• Diabetes
• Infections
• Nutritional deficiencies

How do vitamins affect your energy levels?

Vitamins and minerals are essential for the proper functioning of the metabolism, the nervous system, and cellular energy production. When they are deficient, the body begins to show symptoms, fatigue being one of the most common.

Some of the vitamins related to the feeling of exhaustion are:

• Vitamin B12: It is essential for the production of red blood cells and the functioning of the nervous system. Deficiency can cause anemia, muscle weakness, difficulty concentrating, and severe fatigue.
• Vitamin D: It helps maintain strong bones and modulates the immune system. Low levels can be associated with fatigue, muscle aches, and low mood.
• Iron: Although it is not a vitamin, it is crucial to mention it, since its deficiency (iron deficiency anemia) is one of the main causes of fatigue in women and children.
• Folic acid (vitamin B9): Its deficiency can cause megaloblastic anemia, which reduces cellular oxygenation and causes fatigue.
• Magnesium: It supports energy metabolism and neuromuscular balance. A deficiency can cause exhaustion, cramps, and stress.

How do you know if your fatigue is due to a nutritional deficiency?

Although some symptoms may suggest a deficiency in certain vitamins, the only reliable way to determine this is through clinical laboratory tests. These tests allow blood micronutrient levels to be assessed and thus accurately detect deficiencies.

At La Trigaleña Clinical Laboratory, we recommend some of the following tests:

1. Vitamin Profile

Evaluates levels of B vitamins (B1, B6, B12), vitamin D, and folic acid. It is ideal for patients with symptoms such as weakness, loss of appetite, neurological disorders, or mood swings.

2. Vitamin B12 and Folic Acid Dosage

Key to energy and red blood cell production. Their measurement helps rule out hematological causes of fatigue.

3. Vitamin D Levels

Especially useful for people who spend little time in the sun. Low levels may be related to chronic fatigue.

4. Complete Blood Count

It detects anemia, infections, or general hematological disorders. It is a basic but very useful test.

5. Ferrokinetic Profile (iron, ferritin, transferrin)

It determines if there is an iron deficiency in the body, a common cause of exhaustion, especially in women.

6. Serum Electrolytes and Magnesium

Mineral balance is essential for physical and mental performance.

When should you get these tests done?

If you experience any of the following symptoms for more than two weeks, it is advisable to see a specialist and have laboratory tests done:

• Persistent fatigue with no apparent cause
• Difficulty concentrating or remembering things
• Muscle weakness or frequent cramps
• Dizziness or palpitations
• Irritability or depression with no clear cause
• Paleness or dry skin
• Changes in appetite or weight
