Chronic Fatigue: What Actually Helps
Beyond "just take B12" advice
TL;DR
First: rule out medical causes (thyroid, anemia, sleep apnea). Then: address common deficiencies (D, B12, Iron, Magnesium). Consider: CoQ10 (cellular energy), adaptogens (stress-induced fatigue). Skip: energy drinks and stimulant-heavy supplements (band-aids, not solutions).
Editor's note: Chronic fatigue can signal serious medical conditions. This guide is for unexplained fatigue after medical causes are ruled out.
Medical Causes First
Before supplementing, get tested: thyroid function (TSH, T3, T4), iron and ferritin, B12, vitamin D, basic metabolic panel. Many "unexplained" fatigue cases have identifiable causes. No supplement fixes hypothyroidism. Don't guess. Test.
Key Takeaway: Test before you supplement. Medical causes need medical treatment.
The Big Four Deficiencies
Four deficiencies commonly cause fatigue: Iron (especially in menstruating women), B12 (absorption issues, vegetarian diets), Vitamin D (indoor lifestyles), Magnesium (chronic stress). If any is low, correcting it often dramatically improves energy. But supplementing when NOT deficient usually doesn't help.
Key Takeaway: Deficiency correction works. Random supplementation doesn't.
CoQ10 and Cellular Energy
CoQ10 is essential for mitochondrial energy production. Levels decline with age and statin use. Some chronic fatigue patients show low CoQ10. Supplementing with 100-200mg ubiquinol (better absorbed form) may help, especially in older adults. Takes 4-8 weeks to notice.
Key Takeaway: CoQ10 supports cellular energy. Consider if over 40 or on statins.
Adaptogens for Stress Fatigue
If your fatigue correlates with chronic stress, adaptogens may help. Ashwagandha has best evidence (reduces cortisol over time). Rhodiola may help acute fatigue and mental exhaustion. Both need weeks of consistent use. Neither works for fatigue from sleep deprivation.
Key Takeaway: Adaptogens help stress-induced fatigue. Not all fatigue.
What Doesn't Work
Energy drinks: temporary stimulation, then crash. High-dose B vitamins when not deficient: expensive urine. "Adrenal fatigue" supplements: adrenal fatigue isn't a real medical diagnosis. Random herbal energy blends: usually underdosed or unproven ingredients.
The Uncomfortable Truth
Sometimes fatigue isn't fixable with supplements. It's fixable with sleep, exercise, stress management, or addressing underlying depression. No pill replaces 7-8 hours of sleep. No herb compensates for zero exercise. Sometimes the answer isn't in a bottle.
Key Takeaway: Supplements can't fix lifestyle causes.
Real Talk
The supplement industry loves fatigued people. You're desperate. You'll try anything. But desperation makes you vulnerable to products that promise energy and deliver caffeine (or nothing). Real solutions address causes. Band-aids just delay real fixes.
What To Do About It
- Get medical testing first (thyroid, iron, B12, D)
- Correct any identified deficiencies
- Consider CoQ10 if over 40 or on statins
- Try adaptogens for stress-related fatigue
- Fix sleep, exercise, and stress before adding supplements
- Avoid stimulant-heavy "energy" products
The Bottom Line
Fatigue supplements work when they address the cause. Otherwise, they're expensive disappointment.
