Chronic fatigue: what natural solutions are there to regain energy?

Persistent fatigue, not explained by physical exertion or temporary lack of sleep, affects a growing number of adults. When it becomes chronic, it can impact concentration, memory, motivation, and quality of life. Certain studied natural supplements can support a return to physical and mental energy, as a complement – not a replacement – for medical advice if fatigue persists.

What is chronic fatigue?

Chronic fatigue refers to a state of exhaustion that lasts for several months despite sufficient rest. It can be linked to prolonged stress, nutritional deficiency, a sleep disorder, or an underlying pathology that requires a medical diagnosis [1].

Common causes of prolonged fatigue

• Iron, magnesium, vitamin B, or D deficiency [2]
• Chronic stress, anxiety, or burnout [3]
• Chronic fatigue syndrome (myalgic encephalomyelitis), medical diagnosis [4]
• Hormonal imbalances (thyroid, adrenals)
• Poor lifestyle: sedentary behavior, unbalanced diet

Dietary supplements studied for fatigue

Iron and Vitamin B12

Essential for red blood cell production, iron and vitamin B12 support tissue oxygenation. Deficiencies are common in women and vegetarians [2][5].

Magnesium

A magnesium deficiency is associated in the literature with fatigue, sleep disorders, and irritability [6].

B Vitamins

Vitamins B1, B2, B6, B9, and B12 are involved in energy metabolism and nervous system function [7].

Adaptogenic plants: ginseng, ashwagandha

Ginseng and ashwagandha are plants studied for their possible effect on stress resistance and mental fatigue [8].

Practical advice

• Adopt a regular sleep pattern (7 to 9 hours per night)
• Reduce stimulants like coffee, alcohol, or sugar
• Engage in moderate physical activity: walking, yoga, cycling
• Consult a doctor if fatigue persists, to rule out an underlying medical cause
