Chronic Fatigue: Causes, Natural Solutions, and Recommended Products

Chronic fatigue affects more and more active adults, causing a decrease in productivity, motivation, and daily energy. When it persists despite rest, it becomes essential to seek its causes and consider scientifically studied natural solutions, in addition to medical advice if it persists beyond a few weeks.

What is chronic fatigue?

Chronic fatigue is defined as a persistent feeling of mental and physical exhaustion that does not disappear after rest. It can be linked to deficiencies, hormonal imbalance, chronic stress, or other medical causes that require professional diagnosis.

Common causes of chronic fatigue

  • Iron or vitamin B12 deficiency [1]
  • Magnesium deficiency [2]
  • Non-restorative sleep or sleep apnea
  • Chronic stress or professional burnout
  • Thyroid problems (hypothyroidism) [3] — to be screened by a doctor
  • Chronic fatigue syndrome (ME/CFS), a medical diagnosis

Studied food supplements

Ginseng

An adaptogenic plant, some studies suggest its effect on stress resistance and feelings of fatigue [4].

Magnesium

Involved in energy metabolism and neuromuscular relaxation. Often insufficient in stressed individuals [2].

Vitamin B12 and iron

Essential for red blood cell formation and tissue oxygenation. A deficiency can lead to significant fatigue [1].

Practical tips to combat fatigue

  • Adopt a diet rich in vegetables, oilseeds, and whole grains
  • Engage in moderate exercise (30 min/day)
  • Limit refined sugar and stimulants
  • Improve sleep quality: avoid screens 1 hour before bed
  • Consult a doctor if fatigue persists beyond a few weeks
