Metabolic Health

Fatigue

ICD: R53.83

Chronic fatigue is one of the most common health complaints, with many possible underlying causes. Addressing nutritional deficiencies (B12, iron, vitamin D) and supporting cellular energy production with CoQ10, B vitamins, and adaptogens can help restore vitality.

Overview

Understanding Fatigue

Fatigue goes beyond normal tiredness—it’s a persistent lack of energy that affects daily functioning and doesn’t improve fully with rest. While often a symptom of another condition, fatigue itself significantly impacts quality of life.

Common Causes of Fatigue

  • Nutritional deficiencies: Iron, B12, vitamin D, magnesium
  • Sleep disorders: Sleep apnea, insomnia
  • Thyroid dysfunction: Hypothyroidism, Hashimoto’s
  • Mental health: Depression, anxiety, chronic stress
  • Chronic conditions: Diabetes, heart disease, autoimmune disorders
  • Medications: Many drugs cause fatigue as a side effect
  • Mitochondrial dysfunction: Impaired cellular energy production

When to Investigate Further

Persistent fatigue lasting more than 2 weeks warrants medical evaluation to rule out underlying conditions. Blood tests can identify many treatable causes.

Natural Approaches

Address Potential Deficiencies First

Vitamin B12
Deficiency is common, especially in vegetarians and older adults. Causes fatigue, weakness, and neurological symptoms. Test levels; supplement sublingual B12 (1000mcg) or methylcobalamin if low.

Iron
Iron deficiency anemia is a leading cause of fatigue, especially in women. Test ferritin (storage iron) and hemoglobin. Supplement only if deficient—excess iron is harmful.

Vitamin D
Low vitamin D strongly correlates with fatigue. Test 25-OH vitamin D; supplement to reach 40–60 ng/mL if low (typically 2000–5000 IU daily).

Magnesium
Involved in over 300 enzymatic reactions including energy production. Deficiency is common. 200–400mg/day glycinate or malate form.

Energy Support

CoQ10
Essential for mitochondrial energy production. Levels decline with age and statin use. 100–200mg/day may improve energy, especially in those over 50 or on statins.

Rhodiola Rosea
Excellent adaptogen for mental and physical fatigue. Multiple studies show improvement in fatigue scores. 200–400mg/day, standardized extract.

B Complex Vitamins
Essential for energy metabolism. High-quality B complex may improve energy and reduce fatigue, especially in those with marginal intake.

Ashwagandha
Helps with stress-related fatigue and improves energy by supporting adrenal function. 300–600mg/day standardized extract.

Lifestyle Factors

  • Prioritize sleep quality (7–9 hours)
  • Regular moderate exercise (actually increases energy)
  • Stay hydrated
  • Limit caffeine (can worsen fatigue long-term)
  • Manage stress
  • Eat regular, balanced meals

Conventional Treatments

  • Treatment of underlying cause: Thyroid medication, CPAP for sleep apnea, etc.
  • Iron supplementation: If deficient
  • B12 injections: For deficiency or absorption issues
  • Stimulant medications: In specific conditions (narcolepsy, ADHD)

This section provides context about standard medical treatments. Consult a healthcare provider for personalized advice.

Compounds That May Help

Vitamin B12

Strong

Vitamin B12 is essential for nerve function, DNA synthesis, and red blood cell formation. It's found almost exclusively in animal products, making supplementation important for vegans. Absorption decreases with age and certain medications. Deficiency can cause irreversible nerve damage if untreated.

Iron

Strong

Iron is essential for oxygen transport (hemoglobin), energy production (cytochromes), and DNA synthesis. Iron deficiency is the most common nutritional deficiency globally and can cause anemia, fatigue, and cognitive impairment. Excess iron is toxic, so supplementation should generally be reserved for documented deficiency.

Vitamin D

Strong

Vitamin D is a fat-soluble vitamin that functions more like a hormone, affecting nearly every tissue in the body. It's synthesized in skin from sunlight but many people are deficient due to indoor lifestyles, sunscreen use, and geographic location. It's essential for calcium absorption, bone health, immune function, and mood.

Coenzyme Q10

Moderate

CoQ10 is a naturally occurring compound essential for energy production in every cell. It is a crucial component of the electron transport chain in mitochondria and is especially important for high-energy organs like the heart. Statin drugs deplete CoQ10, making supplementation particularly relevant for statin users.

Rhodiola Rosea

Moderate

Rhodiola rosea is an adaptogenic herb native to cold, mountainous regions. Traditionally used to increase stamina and mental capacity, modern research supports its use for mental and physical fatigue, stress resilience, and cognitive performance, with some evidence for mood support.

Magnesium

Strong

Magnesium is the fourth most abundant mineral in the body and is involved in over 300 enzymatic reactions. It's essential for energy production, muscle and nerve function, blood sugar control, and blood pressure regulation. Deficiency is surprisingly common (up to 50% of the population) and linked to numerous health issues.

Vitamin B1

Strong

Vitamin B1 (Thiamine) is a water-soluble vitamin essential for carbohydrate metabolism and energy production. It plays a critical role in nerve function and is vital for preventing beriberi and Wernicke-Korsakoff syndrome.

Vitamin B2

Moderate

Vitamin B2 (Riboflavin) is a water-soluble vitamin crucial for energy metabolism and cellular function. It serves as a precursor to flavin coenzymes (FAD and FMN) involved in numerous metabolic reactions. High-dose riboflavin has shown promise for migraine prevention.

Persistent fatigue can indicate serious underlying conditions. See a healthcare provider for evaluation, especially if fatigue is severe, accompanied by other symptoms, or lasts more than 2 weeks.
