Vitamin B12 and folate deficiency can be one of the main reasons for chronic fatigue in individuals. This deficiency is increasing for various reasons, and specialists have been examining it. Chronic fatigue is one of the most common symptoms for which individuals seek medical attention. Research shows that the deficiency of these two B vitamins, namely vitamin B12 and folate (B9), may play a larger role in the occurrence of this problem than previously thought.
The Role of Vitamins in Physical and Mental Health
Vitamin B12 and folate play a role in a wide range of metabolic processes in the body. These substances are essential for DNA synthesis, tissue growth and repair, as well as the production of certain neurotransmitters in the brain that are related to mood and motivation. However, in many cases, diagnosing fatigue is not straightforward, and doctors usually focus on iron deficiency or diabetes.

According to doctors, nearly any illness can somehow cause feelings of fatigue. Pregnancy, depression, carbon monoxide poisoning, and chronic fatigue syndrome are among the possible causes. The British medical guidelines for investigating fatigue also include testing B12 and folate levels in the list of potential examinations; however, these tests are usually not the first tests prescribed for a person suffering from fatigue.
Challenges in Diagnosis and Treatment
Blood tests for measuring B12 and folate do not always provide an accurate picture of the body's status, as the levels of these substances in the blood do not necessarily reflect their amounts in the body's tissues. Testing for a substance called 'homocysteine' may provide more accurate information. Homocysteine plays a role in the same metabolic processes that depend on B12 and folate, and in individuals with a deficiency of these vitamins, blood homocysteine levels typically increase. However, general practitioners often do not have the ability to directly request this test, and it usually must be prescribed by a hospital doctor.
A new study in Japan has further illustrated the complexity of this relationship. Researchers examined over 600 individuals regarding physical fatigue and what could be termed 'mental fatigue.' The results showed that higher levels of homocysteine, which can be a sign of B12 or folate deficiency, were associated with more severe fatigue in men. In women, this condition was linked to decreased mental motivation for activities.
However, researchers emphasize that this study does not prove that the deficiency of these vitamins directly causes fatigue in individuals. They believe that for individuals suffering from chronic fatigue, exploring the possibility of treatment with supplements of these vitamins could be valuable. Even when blood test results are normal or near the lower limit, a doctor may suggest treatment if symptoms and risk factors are present.
Prevention and Management of Symptoms
B12 deficiency is not limited to fatigue. Mouth sores, tingling sensations in the legs, memory problems, and 'brain fog' can also be symptoms. These symptoms usually develop gradually, and some individuals may attribute these changes to the natural aging process. Nutrition can play a role in preventing the deficiency of these vitamins. Meat and fortified food products, including some breakfast cereals, are suitable sources of B12. Folate is also found in legumes, beans, and leafy green vegetables.
Experts ultimately recommend that chronic fatigue should not be ignored. If feelings of fatigue persist for a long time, consulting a doctor can help identify the underlying cause; as behind this seemingly simple symptom, there may be a treatable problem.
