Study Links B12 and Folate Deficiency to Chronic Fatigue in U.S. Population
A recent study has identified a potential link between deficiencies in vitamin B12 and folate (vitamin B9) and chronic fatigue, a condition affecting over 3 million people in the United States. Chronic fatigue is characterized by persistent tiredness that interferes with daily activities, and it is more prevalent in women than men. The study, published in Nutrients, suggests that individuals with elevated levels of homocysteine, a biomarker indicating deficiency in these vitamins, are more likely to experience fatigue and lack of motivation. While the study does not establish causation, it highlights the importance of maintaining adequate levels of B vitamins to potentially reduce fatigue-related outcomes. Experts believe that chronic fatigue may follow viral infections or extreme physical stress, such as major surgery.
