Natural Remedies for Fatigue

What is Fatigue?

Chronic fatigue is persistent tiredness not relieved by rest that impacts daily functioning. While sometimes related to an underlying condition, many people experience fatigue due to lifestyle factors that respond well to natural interventions.

Prevalence: Fatigue is one of the most common complaints in primary care, affecting about 20-25% of the general population. It is more prevalent in women and increases with age.

Evidence-Based Remedies

Iron-Rich Foods

Strong Evidence

Iron deficiency is one of the most common nutritional causes of fatigue. Increasing dietary iron from both heme (animal) and non-heme (plant) sources can help restore energy levels.

Suggested Dosage

Include iron-rich foods daily: lean red meat, spinach, lentils, fortified cereals. Pair with vitamin C for better absorption.

Safety Warnings

Do not supplement iron without first getting a blood test -- excess iron is toxic. Iron supplements can cause constipation and stomach upset.

Rhodiola Rosea

Moderate Evidence

An adaptogenic herb that may improve energy, mental performance, and exercise capacity by supporting the body's stress response and optimizing neurotransmitter levels.

Suggested Dosage

200-600mg standardized extract daily, taken in the morning

Safety Warnings

May cause insomnia if taken too late in the day. May interact with antidepressants. Start with a lower dose.

B Vitamin Complex

Strong Evidence

B vitamins are essential for energy metabolism. Deficiencies in B12, B6, or folate are common causes of fatigue, especially in older adults and those on restrictive diets.

Suggested Dosage

A quality B-complex supplement daily, or focus on B12 (2.4mcg) and B6 (1.3-1.7mg)

Safety Warnings

B vitamins may turn urine bright yellow (harmless). Very high doses of B6 can cause nerve damage. B12 injections may be needed if absorption is impaired.

Sleep Hygiene

Strong Evidence

Optimizing sleep environment and habits is foundational for fighting fatigue: consistent schedule, dark/cool room, limited screens before bed, and avoiding caffeine after noon.

Suggested Dosage

Aim for 7-9 hours nightly. Maintain consistent sleep and wake times, even on weekends.

Safety Warnings

Sudden changes to sleep schedule can temporarily worsen fatigue. Implement changes gradually. If good sleep hygiene does not resolve fatigue, seek medical evaluation.

Frequently Asked Questions

Can dehydration cause fatigue?

Yes, even mild dehydration (1-2% of body weight) can significantly increase feelings of fatigue, reduce concentration, and worsen mood. Many people mistake thirst for tiredness. Aim for 8 glasses of water daily and more during exercise or hot weather.

Why am I always tired even when I sleep enough?

Several factors can cause daytime fatigue despite adequate sleep hours: poor sleep quality (sleep apnea, frequent waking), nutritional deficiencies (iron, B12, vitamin D), chronic stress, sedentary lifestyle, or underlying medical conditions (thyroid disorders, anemia, diabetes). A medical evaluation can help identify the cause.

Does exercise help with fatigue or make it worse?

Regular moderate exercise actually reduces fatigue by improving cardiovascular fitness, sleep quality, and mood. While you may feel tired immediately after exercise, consistent physical activity (150 minutes per week) leads to increased energy levels over time. Start gently if you are currently sedentary.
