Is Omega-3 Index useful for Müdigkeit?

The Omega-3 Index measures EPA and DHA levels in red blood cells and is primarily validated for cardiovascular risk assessment. For fatigue (Müdigkeit), the evidence is limited and mixed. Some observational studies suggest that low omega-3 levels are associated with higher fatigue, especially in inflammatory or autoimmune conditions. However, interventional trials have not consistently shown that raising the index reduces fatigue in the general population. Therefore, while the Omega-3 Index may provide supportive information in specific clinical contexts (e.g., chronic fatigue syndrome, depression), it is not a standard diagnostic tool for fatigue. Lifestyle factors such as sleep, stress, and nutrition are more impactful. Evidence: human-moderate. Caveat: do not use the index alone to diagnose or treat fatigue without medical guidance.
