‘Tired all the time’ is a popular complaint. According to international studies in general practice, 25–30% of the complaints were concerning fatigue. Fatigue is a feeling of constant tiredness or weakness in the form of physical, mental, or a combination of both. On a whole, fatigue may be caused by general well-being issues such as lifestyle, social interaction, and emotion. In fact, fatigue has distinct mental and physical components. Physical fatigue is the somatic sensation of fatigue while mental fatigue is a condition triggered by prolonged cognitive activity. It sends your brain into overdrive, leaving you exhausted, hampering your productivity and overall cognitive function.
Our organs, muscles, and cell metabolism all need various nutrients to support daily function. Nutrients may be directly converted to provide energy, or as coenzymes, that involved in energy production. Nutrient deficiency will negatively impact tissue repair and decrease energy levels which lead to chronic fatigue or diseases. Severe fatigue accompanied by numerous common symptoms such as headache, muscle pain and loss of concentration which last for 6 months or more can lead to chronic fatigue syndrome, a fatigue-specific medical disorder.
